Protecting the environment

ENVIRONMENTAL NOTE Environmental damage due to operating conditions and personal driving style

The pollutant emission of the vehicle is directly related to the way you operate the vehicle.

Operate your vehicle in an environmentally responsible manner to help protect the environment. Please observe the following recommendations on operating conditions and personal driving style.

Operating conditions:

Make sure that the tire pressure is correct.
Do not carry any unnecessary weight (e.g. roof luggage racks once you no longer need them).
Adhere to the service intervals. A regularly serviced vehicle will contribute to environmental protection.

Always have maintenance work carried out at a qualified specialist workshop.

Personal driving style:

Do not depress the accelerator pedal when starting the engine.
Do not warm up the vehicle while stationary.
▶ Drive carefully and maintain a suitable distance from the vehicle in front.
▶ Avoid frequent, sudden acceleration and braking.
Change gear in good time and use each gear only up to 23 of its maximum engine speed.
▶ Switch off the vehicle in stationary traffic, e.g. by using the ECO start/stop function.
▶ Drive in a fuel-efficient manner. Observe the ECO display for an economical driving style.

Plug-in hybrid

ENVIRONMENTAL NOTE Environmental pollution caused by irresponsible disposal of the high-voltage battery

A high-voltage battery contains materials which are harmful to the environment.

▶ Dispose of defective high-voltage batteries at a qualified specialist workshop.

Environmental issues and recommendations:

It is recommended that you re-use or recycle materials instead of just disposing of them.

The relevant environmental guidelines and regulations serve to protect the environment and must be strictly observed.

Mercedes-Benz GenuineParts

ENVIRONMENTAL NOTE Environmental damage due to not using recycled reconditioned components

Mercedes-Benz AG offers recycled reconditioned components and parts with the same quality as new parts. The same entitlement from the Limited Warranty is valid as for new parts.

▶ Use recycled reconditioned components and parts from Mercedes-Benz AG.

Possible danger due to substances hazardous to health

In compliance with Proposition 65 ("Prop65"), the following detachable label has been added to each vehicle sold in California:

WARNING

Operating, servicing and maintaining a passenger vehicle, pickup truck, van or off-road motor vehicle can expose you to chemicals including engine exhaust, carbon monoxide, phthalates, and lead, which are known to the State of California to cause cancer and birth defects or other reproductive harm. To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area and wear gloves or wash your hands frequently when servicing your vehicle. For more information go to www.P65Warnings.ca.gov/passenger-vehicle

Operating safety

WARNING Risk of accident due to mal- functions or system failures

If you do not have the prescribed service/maintenance work or any required repairs carried out, this could result in malfunctions or system failures.

▶ Always have the prescribed service and maintenance work or any required repairs carried out in a qualified specialist workshop.

A

WARNING Risk of accident or injury due to incorrect modifications on electronic component parts

Modification of electronic components, their software or wiring could impair their function and/or the function of other networked component parts or safety-relevant systems.

This can endanger the operating safety of the vehicle.

▶ Never tamper with the wiring and electronic component parts or their software.
You should have all work on electrical and electronic components carried out at a qualified specialist workshop.

Observe the "On-board electronics" section in "Technical data".

A

WARNING Risk of fire caused by flammable material on hot exhaust system components

Flammable material such as leaves, grass or twigs may ignite if they come into contact with hot parts of the exhaust system.

When driving on an unpaved road or off-road, check the vehicle underside regularly.
In particular, remove trapped plant parts or other flammable material.
If there is damage, consult a qualified specialist workshop immediately.

!

NOTE Damage to the vehicle due to driving too fast and due to impacts to the vehicle underbody or suspension components

In the following situations, in particular, there is a risk of damage to the vehicle:

• The vehicle becomes grounded, e.g. on a high curb or an unpaved road
• The vehicle is driven too fast over an obstacle, e.g. a curb, speed bump or pot-hole
• A heavy object strikes the underbody or suspension components

In situations such as these, damage to the body, underbody, suspension components, wheels or tires may not be visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, may no longer absorb the resulting force as intended.

If the underbody paneling is damaged, flammable materials such as leaves, grass or twigs can collect between the underbody and the

underbody paneling. These materials may ignite if they come into contact with hot parts of the exhaust system.

Plug-in hybrid

Hybrid vehicles have an internal-combustion engine and at least one electric motor. The energy supply for operating the vehicle electrically is provided by the high-voltage on-board electrical system.

A DANGER Risk of death and fire due to modified and/or damaged components of the high-voltage on-board electrical system

The vehicle's high-voltage on-board electrical system is under high voltage. If you modify component parts in the vehicle's high-voltage on-board electrical system or touch damaged component parts, you may be electrocuted. In addition, modified and/or damaged components may cause a fire.

In the event of an accident or impact to the vehicle underbody, components of the high-voltage electrical system may be damaged although the damage is not visible.

▶ Never make any modifications to the high-voltage on-board electrical system.
Do not switch on or use the vehicle if its high-voltage on-board electrical system components have been modified or damaged.

▶ Never touch damaged components of the high-voltage on-board electrical system.
After an accident, do not touch any components of the high-voltage on-board electrical system.
After an accident, have the vehicle transported away.
Have the components of the high-voltage on-board electrical system checked at a qualified specialist workshop and replaced if necessary.

The components of the vehicle's high-voltage on-board electrical system are marked with yellow warning stickers. The cables of the high-voltage on-board electrical system are orange.

Warning symbols including warning triangle, open book, lightning bolt, and hand with hazard symbol

Example

High-voltage components that can become very hot are marked with an additional warning sticker:

Warning symbols including warning, open book, lightning bolt, and hand with text labels

Vehicles with hybrid systems generate significantly less noise when stationary- and when being driven than vehicles with internal-combustion engines.

When you are driving in electric mode, the vehicle may not be heard by other road users due to the significantly lower noise generated when driving and when stationary.

For this reason the vehicle is equipped with a sound generator, which serves as an acoustic vehicle alerting system (AVAS). This protective equipment is prescribed by law.

The outside sound produced by the sound generator (AVAS) can be heard in the passenger compartment at low speeds and does not represent a malfunction.

Vehicles with a 48 V on-board electrical system

DANGER Risk of fatal injury by touching damaged high-voltage components

Vehicles with a 48 V on-board electrical system contain individual high-voltage components. These high-voltage components are under high voltage.

If you modify component parts of these high-voltage components or touch damaged component parts, you may be electrocuted.

High voltage components may be damaged in an accident, although the damage may not be visible.

▶ Never perform modifications to component parts of high-voltage components.
▶ Never touch damaged component parts of high-voltage components.
▶ Never touch component parts of high-voltage components after an accident.

Vehicles with a 48 V on-board electrical system contain high-voltage components. These components are marked with a high-voltage label:

Safety warning symbols including warning triangle, lightning bolt, and hand gesture

Example

All work on high-voltage components must be carried out at a qualified specialist workshop.

Data storage

Data processing in the vehicle

Electronic control units

Your vehicle is installed with electronic control units. Control units process data that they e.g. receive from vehicle sensors, generate themselves or exchange among themselves. Some control units are required for the safe operation of your vehicle, some assist you when driving (e.g. driver assistance systems), while others enable convenience or infotainment functions.

In the following, you will find general information about data processing in the vehicle. Additional information on what specific data is collected, stored and transmitted to third parties for what purpose in your vehicle can be found in the notes on the functional features in question in the respective operating instructions. These are also available online and, depending on the equipment, digitally in the vehicle.

Personal data

Each vehicle is marked with a unique vehicle identification number. Depending on the country, this vehicle identification number can be used by, for example, government authorities to determine the identity of the owner. There are other possibilities for using data collected from the vehicle to identify the owner or driver (e.g. the license plate number).

The data generated or processed by control units may therefore be personal or, under certain conditions, become personal. Depending on what vehicle data is available, it may be possible to make inferences about e.g. your driving behavior, location, route or use patterns.

Legal requirements for the disclosure of data

If legal regulations exist, manufacturers are generally obligated to release data stored by the manufacturer to the necessary extent in individual cases at the request of state authorities. This may be the case during the investigation of a criminal offense, for example.

Within the framework of applicable law, state authorities are also authorized to read out data

from vehicles themselves in specific cases. In the event of an accident, for example, information can be read from the air bag control unit that can help to establish what happened.

Operating data in the vehicle

Control units process data to operate the vehicle.

This includes the following data:

• Vehicle status information such as the speed, longitudinal acceleration, lateral acceleration, number of wheel revolutions or the fastened seat belts display
• Ambient conditions such as temperature, rain sensor or distance sensor

As a rule, this data is volatile, is not stored beyond the operating time and is processed only in the vehicle itself. Control units (e.g. the vehicle key) often contain data memories. These are used to temporarily or permanently document information on the vehicle condition, component stress, maintenance requirements or technical events and malfunctions.

Depending on the technical equipment, the following data is stored:

• Operating status of system components (e.g. fill levels, tire pressure, battery status)
• Malfunctions or faults in important system components (e.g. lights, brakes)
• System reactions in special driving situations (e.g. air bag deployment, the intervention of stability control systems)
  • information on events leading to vehicle damage

In special cases, it may be necessary to store data that would otherwise only be volatile. This may be the case if the vehicle has detected a malfunction, for example.

If you use services such as repair services or maintenance work, stored operational data can be read out and used together with the vehicle identification number, where necessary. It can be read out by service network employees (e.g. workshops and manufacturers) or third parties (e.g. breakdown services). The same applies to warranty cases and quality assurance measures. The data is usually read out via the diagnostics connection in the vehicle, which is required by law. The operating data that is read out documents technical conditions of the vehicle or individual components and helps to diagnose malfunctions, meet warranty obligations and improve quality. This data, in particular information on component stress, technical events, operating errors and other malfunctions, is transmitted to the manufacturer for this purpose together with the vehicle identification number if necessary. In addition, the manufacturer is subject to product liability. For this reason, the manufacturer also uses operational data from the vehicle for e.g. recalls. This data can also be used to check customer claims for warranty and guarantee.

Malfunction memories in the vehicle can be reset during repair or service work or, at your request, by a service company.

Comfort and infotainment functions

You can save comfort settings and customizations in the vehicle and change or reset them at any time. Depending on the vehicle equipment, this includes the following settings:

• Seat positions and steering wheel positions
• Suspension tuning and climate control settings
• Personalized settings (e.g. interior lighting)

You can incorporate data into the vehicle's infotainment functions yourself as part of the selected equipment.

Depending on the vehicle equipment, this includes the following data:

• Multimedia data (e.g. music, films or photos for playback in an integrated multimedia system)
• Address book data for use in conjunction with an integrated hands-free system or integrated navigation system
• Navigation destinations that have been entered
  • Data about using Internet services

This data for comfort and infotainment functions can be saved locally in the vehicle or is stored on

a device that you have connected to the vehicle (e.g. smartphone, USB flash drive or MP3 player). If you have entered data yourself, you can delete it at any time.

The transfer of this data out of the vehicle takes place exclusively at your request. This applies in particular when you are using online services according to the settings you have selected.

Smartphone integration (e.g. Android Auto or Apple CarPlay®)

If your vehicle is equipped appropriately, you can connect your smartphone or another mobile end device to the vehicle. You can then control them using the controls integrated in the vehicle. The smartphone's picture and sound can be output via the multimedia system. Specific items of information are also sent to your smartphone. Depending on the type of integration, this includes position data, day/night mode and other general vehicle statuses. Please refer to the vehicle Operator's Manual / infotainment system operating instructions for further information.

This integration allows the use of selected smartphone apps (e.g. navigation apps, music player

apps). No additional interaction - in particular active access to vehicle data - takes place between the smartphone and vehicle. The type of additional data processing is determined by the provider of the app being used. Whether you can configure settings for it and, if so, which ones, depend on the app and your smartphone's operating system.

Online services

Wireless network connection

If your vehicle has a wireless network connection, it enables data to be exchanged between your vehicle and additional systems. The wireless network connection is made possible by the vehicle's own transmitter and receiver or by a mobile end device that you have brought into the vehicle, for example, a smartphone. Online functions can be used via the wireless network connection. This includes online services and applications/apps provided to you by the manufacturer or by other providers.

Manufacturer's services

Regarding the manufacturer's online services, the individual functions are described by the manufacturer in a suitable place, for example, in the Operator's Manual or on the manufacturer's website, where the relevant data protection information is also given. Personal data may be used for the provision of online services. Data is exchanged via a secure connection, such as the manufacturer's designated IT systems. Any personal data which is collected, processed and used, other than for the provision of services, is done so exclusively on the basis of legal permission. This is the case, for example, for a legally prescribed emergency call system, a contractual agreement or when consent has been given.

You can have services and functions, some of which are subject to a fee, activated or deactivated. This excludes legally prescribed functions and services, such as an emergency call system.

Third-party services

If you use online services from other providers (third parties), these services are the responsibility of the provider in question and subject to that provider's data protection conditions and terms of

use. As a general rule, the manufacturer has no influence on the content exchanged.

For this reason, when services are provided by third parties, please ask the service provider in question for information about the type, extent and purpose of the collection and use of personal data.

Data protection rights

Depending on your country or the equipment and range of functions of your vehicle as well as the services you use and the services on offer, you are entitled to different data protection rights. Further information on data protection and your data protection rights can either be found on the manufacturer's website or you will receive this information as part of the various services and service offers. There you will also find the contact information for the manufacturer and its data protection officers.

At a workshop, for example, with the support of a specialist and possibly for a fee, you can have data read out which is stored only locally in the vehicle.

MBUX multimedia system/Mercedes me connect

If the vehicle is equipped with the MBUX multimedia system or Mercedes me connect, additional data about the vehicle's operation, the use of the vehicle in certain situations, and the location of the vehicle may be compiled by the MBUX multimedia system or Mercedes me connect.

For additional information, please refer to the "MBUX multimedia system" section and/or the Mercedes me connect Terms and Conditions.

Event data recorder

USA only:

This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle's systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.

The EDR in this vehicle is designed to record such data as:

• How various systems in your vehicle were operating;
- Whether or not the driver and passenger safety belts were buckled/fastened;
- How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement,

that have the special equipment, can read the information if they have access to the vehicle or the EDR.

EDR data may be used in civil and criminal matters as a tool in accident reconstruction, accident claims, and vehicle safety. Since the Crash Data Retrieval CDR tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC ("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel.

MBUSA will not share EDR data with others without the consent of the vehicle owners or, if the vehicle is leased, without the consent of the lessee. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local government; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law.

Warning: The EDR is a component of the Restraint System Module. Tampering with, altering, modifying or removing the EDR component may result in a malfunction of the Restraint System Module and other systems.

State laws or regulations regarding EDRs that conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of Dec 2016, 17 states have enacted laws relating to EDRs.

Brief overview of the most important points

Basic information

Make sure that the following prerequisites in particular have been met so that the components of the restraint system are able to provide the intended level of protection:

• Sit correctly (→ page 38).
• Fasten the seat belt correctly (→ page 39).
  Function of the seat belt warning lamp 4 (→ page 41).
• Function of the rear seat belt status display ( page 41).
• The restraint system warning lamp is not lit up after the self-test ( page 40).
• The PASSENGER AIR BAG indicator lamps display the correct status of the front passenger air bag ( page 42).

For clear understanding

The chapter "Occupant safety" includes information on equipment, functions and behaviors that contribute directly to safety of vehicle occupants.

The information is structured as follows:

• The most important information in brief: in this chapter, you are provided with an overview of the relationship between the restraint system and the correct behavior of all vehicle occupants.
• Specific information: in further sections of the chapter "Occupant safety", you can find specific information on the equipment and functions of the restraint system.
• Keyword directory: you can also find certain subjects in this Operator's Manual using the keyword directory.

Information on the following subjects, among others, are not provided in the chapter "Occupant safety":

• Children in the vehicle (→ page 55)
- Driving and driving safety systems (→ page 224)
• Stowage areas ( page 115)

Defining generic terms clearly

In this Operator's Manual, the following generic terms are used:

• Occupant safety: comprises the components and system functions which help to minimize, as much as possible, the stresses on and consequences for vehicle occupants during an accident.
• Restraint system: comprises those components which, along with the vehicle structure, help prevent vehicle occupants from potentially coming into contact with parts of the vehicle interior. The seat belts and air bags, for example, are components of the restraint system.
• Child restraint system: you can find all information on this subject in the chapter "Children in the vehicle" (→ page 55).

Be diligent

For the components of the restraint system to provide the intended level of protection, it is essential that the sitting posture is correct and that the seat belt is correctly fastened.

Note that negligence when adjusting your sitting posture and fastening the seat belt may have serious consequences. Be diligent and make sure that all vehicle occupants are sitting correctly and have fastened their seat belts properly before starting every journey.

Information on the correct seat position

The seat position must be correct in order for the components of the restraint system to provide the intended level of protection.

The seat position influences both the protection provided by the seat belt and the additional protection provided by the air bag.

The correct seat position with an almost upright posture and a correctly fastened seat belt also reduce the risk posed by the air bag when it is deployed.

When choosing the seat, take note of the available space. When you are sitting with the right posture in a nearly upright position, your head should not touch the roof.

WARNING Risk of injury or death due to an incorrect seat position

If you deviate from the correct seat position, the air bag cannot provide its intended protective function.

Each vehicle occupant must make sure of the following.

▶ Put the seat in the correct position.
Fasten seat belts correctly. Pregnant women must take particular care to ensure that the lap belt never lies across the abdomen.
▶ Observe the following information.

In order for the restraint system to provide the intended level of protection, observe the following information:

- Before starting your journey, adjust your seat correctly ( page 98).

When doing so, make sure you are able to fasten your seat belt correctly. The shoulder belt strap must be routed forward from the seat belt outlet over the center of your shoulder.

• Keep your distance from the air bags, especially the front air bags. Set the driver's seat and front passenger seat as far back as possible while making sure the seat belt is fastened correctly.
• If persons are sitting on the rear seats, vehicle occupants should maintain a sufficient distance to the parts of the vehicle interior in front of them.
• Make sure there are no people, animals or objects between the vehicle occupants and an air bag.
• If you are the driver, observe the following information on the correct position of the driver's seat ( page 98).

Hold the steering wheel only by the steering wheel rim. This allows the driver's air bag to fully deploy.

- Assume a nearly upright position, with your buttocks as far back as possible in the gap between the seat cushion and seat backrest. This ensures that your back lies as flat and firmly as possible against the seat backrest.

• While driving, do not lean forward and do not lean against the door or side window. You may otherwise be in the deployment area of the air bags.
• Sit with your feet resting on the floor, if possible. Your thighs are slightly supported by the seat cushion
  Do not put your feet up on the cockpit, for example. Your feet may otherwise be in the deployment area of the air bag.
• Fasten the seat belt correctly.

Notes on wearing the seat belt correctly

Always fasten your seat belt correctly before starting a journey. A seat belt can provide the best level of protection only if it is worn correctly.

WARNING Risk of injury or death due to incorrectly fastened seat belt

If the seat belt is not worn correctly, it cannot perform its intended protective function.

In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly.

▶ Always ensure that all vehicle occupants have their seat belts fastened correctly and are sitting properly.

WARNING Risk of injury or death when additional restraint systems are not used for persons with a smaller stature

Persons under 5 ft (1.50 m) tall cannot wear the seat belt correctly without a suitable additional restraint system.

▶ Always secure persons under 5 ft (1.50 m) tall in a suitable restraint system.

Each vehicle occupant must observe the following notes in particular:

• The seat belt must not be twisted:

• The shoulder belt strap must be routed forward from the seat belt outlet over the center of your shoulder.
• The shoulder belt strap should neither touch your neck nor be routed under your arm or behind your back.
• The lap belt must be routed as low down across the hips as possible.
  In addition, push the lap belt down as far as possible across your hips and pull tight with the shoulder belt strap. Never route the lap belt across your abdomen.
  Pregnant women must also take particular care with this.
• The shoulder belt strap and lap belt must fit snugly against the body after being tightened.
• Avoid wearing bulky clothing, e.g. a winter coat.
• Never route the seat belt across sharp, pointed, abrasive or fragile objects.
• Only one person should use each seat belt at any one time.

- Never secure objects with a seat belt if the seat belt is also being used by one of the vehicle's occupants.

Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat.

Fastening and adjusting seat belts

If the seat belt is pulled quickly or sharply, the seat belt retractor locks. The seat belt strap cannot be pulled out any further.

Diagram showing car seatbelt usage with numbered instructions for driving a seatbelt

Always engage seat belt tongue ① of the seat belt into seat belt buckle ② of the corresponding seat.
To adjust the seat belt height: press button 3 on the seat belt outlet and slide the seat belt outlet to the desired position.
To engage the seat belt outlet: release button ③ and ensure that the seat belt outlet engages.

NOTE Deployment of components of the restraint system when the front passenger seat is unoccupied and a seat belt is buckled

When the front passenger seat is unoccupied and the seat belt tongue of the seat belt is engaged in the seat belt buckle, components of the restraint system may deploy unnecessarily on the front passenger side, e.g. the Emergency Tensioning Device.

▶ Only buckle the seat belts as intended.

① Observe the information on child seat safety feature of the seat belt ( page 63).

Function of the restraint system warning lamp

When the vehicle is switched on, a self-test is performed, during which the restraint system warning lamp lights up. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are then functional.

A malfunction has occurred in the restraint system if:

• the restraint system warning lamp does not light up when the vehicle is switched on
• the restraint system warning lamp lights up continuously or repeatedly during a journey

If components of the restraint system have been deployed, the restraint system warning lamp lights up continuously.

WARNING Risk of injury due to malfunctions in the restraint system

Components in the restraint system may be activated unintentionally or not deploy as planned in an accident.

Have the restraint system checked and repaired immediately at a qualified specialist workshop.

Plug-in hybrid vehicles: if the restraint system is malfunctioning, the automatic high voltage emergency shutoff may not function.

The front passenger air bag may be deployed during an accident. Observe the following information on the correct seat position ( page 38).

Vehicles with rear seats: a person of smaller stature should use a rear seat.

System limits

The front passenger air bag may otherwise be disabled by mistake, for example, in the following situation:

• The front passenger transfers their weight by supporting themselves on a vehicle armrest.
• The front passenger sits in such a way that their weight is raised from the seat surface.

NOTE Deployment of components of the restraint system when the front passenger seat is unoccupied

In an accident, the components of the restraint system may deploy unnecessarily on the front passenger side if:

• There are heavy objects on the front passenger seat.
• The seat belt tongue is engaged in the seat belt buckle of the front passenger seat and the front passenger seat is unoccupied.

▶ Store objects in a suitable place.

▶ Only one person should use each seat belt at any one time.

Depending on the detected accident situation, the window air bag on the front passenger side may deploy. The air bag is deployed regardless of whether the front passenger seat is occupied.

Function of PRE-SAFE® (anticipatory occupant protection)

PRE-SAFE ^® is able to detect certain critical driving situations and implement pre-emptive measures to protect the vehicle occupants.

PRE-SAFE ^® can implement the following measures independently of each other:

• Tightening the seat belts on the driver's seat and front passenger seat.
• Closing the side windows.
• Vehicles with sliding sunroof: closing the sliding sunroof.
• Vehicles with memory function: moving the front passenger seat to a more favorable seat position.

- PRE-SAFE® Sound: provided that the multimedia system is switched on, generating a brief noise signal to stimulate the innate protective mechanism of a person's hearing.

NOTE Damage caused by objects in the footwell or behind the seat

The automatic adjustment of the seat position may result in damage to the seat and/or the object.

▶ Stow objects in a suitable place.

Reversing the PRE-SAFE® system measures

If an accident did not occur, the pre-emptive measures that were taken will be reversed.

You will need to perform certain settings yourself.

If the seat belt pre-tensioning is not reduced, move the seat backrest back slightly. The locking mechanism will release.

Function of PRE-SAFE® PLUS (anticipatory occupant protection plus)

PRE-SAFE® PLUS can detect certain impacts, particularly an imminent rear impact, and take preemptive measures to protect the vehicle occupants. These measures cannot necessarily prevent an imminent impact.

PRE-SAFE® PLUS can implement the following measures independently of each other:

• Tightening the seat belts on the driver's seat and front passenger seat.
• Increasing brake pressure when the vehicle is stationary. This brake application is canceled automatically when the vehicle pulls away.

If an accident did not occur, the pre-emptive measures that were taken are reversed.

System limits

The system will not initiate any action in the following situations:

- When backing up

The system will not initiate any braking application in the following situations:

• Whilst driving or
• When entering or exiting a parking space while using Active Parking Assist

Function of PRE-SAFE® Impulse Side

If an imminent side impact is detected, PRE-SAFE® Impulse Side can pre-emptively move the upper body of the vehicle occupant on the front seat towards the center of the vehicle. It does this by rapidly inflating an air cushion in the outer seat side bolster of the seat backrest on the side on which the impact is anticipated. This increases the distance between the door and the vehicle occupant.

If PRE-SAFE ^® Impulse Side has been deployed or is faulty, the PRE-SAFE Pulse Side Inoperative See Operator's Manual(→ page 448) display message will appear.

Seat belt adjustment function

Vehicles with PRE-SAFE®: after you have fastened the seat belt of the front seat, it may adjust itself against your body by pulling at the shoulder until somewhat tight. Do not hold the seat belt tightly while it is adjusting.

This function is a reminder that all vehicle occupants must wear their seat belts correctly.

You can activate and deactivate the seat belt adjustment function using the multimedia system ( page 47).

Overview of the automatic measures after an accident

Depending on the type and severity of the accident, and depending on the vehicle's equipment, the following measures can be implemented, forexample:

• automatic braking (post-collision brake)
- activating the hazard warning lights
- triggering an automatic emergency call ( page 352)
- Switching off the engine

To start the vehicle again, switch the vehicle off and on once more ( page 172). Depending on the type and severity of the accident, you may no longer be able to start the vehicle.

• switching off the fuel supply
- Plug-in hybrid: switching off the hybrid system and high-voltage on-board electrical system
- unlocking the vehicle doors
• lowering the side windows
- displaying the emergency guide in the central display

• switching on the interior lighting

Function of the post-collision brake after an accident

Depending on the accident situation, the post-collision brake can minimise the severity of a further collision or even avoid it.

If an accident is detected, the post-collision brake can initiate automatic braking. When the vehicle has come to a standstill, the electric parking brake is automatically applied.

The driver can cancel automatic braking by taking the following actions:

• Braking more strongly than automatic braking
  • Fully depressing the accelerator pedal with force

Purpose and function of the restraint system

Overview of deployment situations (restraint system)

Make sure that the following prerequisites in particular have been met so that the components of the restraint system are able to provide the intended level of protection:

• Sit correctly (→ page 38).
• Fasten the seat belt correctly (→ page 39).

- Function of the seat belt warning lamp (→ page 41).

- Function of the rear seat belt status display ( page 41).

• The restraint system warning lamp is not lit up after the self-test (→ page 40).
• The PASSENGER AIR BAG indicator lamps display the correct status of the front passenger air bag ( page 42).

Depending on the detected deployment situation, the components of the restraint system can be activated or deployed independently of each other:

• Emergency Tensioning Device: frontal impact, rear impact, side impact, rollover
- Driver's air bag, front passenger air bag: frontal impact
- Knee bag: frontal impact
- Side impact air bag: side impact
- Window curtain air bag: side impact, rollover, frontal impact
- PRE-SAFE ^ Impulse Side: side impact

The installation location of an air bag is identified by the AIRBAG symbol ( page 53).

Observe the information on the function of the restraint system ( page 48).

Information on how the restraint system works

How the restraint system functions depends on the severity of the impact detected and the apparent type of accident.

For more information about types of accidents, see "Overview of deployment situations" ( page 48).

The activation thresholds for the components of the restraint system are determined based on the evaluation of the sensor values measured at various points in the vehicle. This process is pre-emptive in nature. The triggering/deployment of the components of the restraint system must take place in good time at the start of the collision.

Factors that can be seen and measured only after a collision has occurred cannot play a decisive role in air bag deployment. Nor do they provide an indication of air bag deployment.

The vehicle may be deformed significantly without an air bag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of vehicle deceleration is not high. Conversely, an air bag may be deployed even though the vehicle suffers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, this may result in sufficiently high levels of vehicle deceleration.

Depending on the apparent type of accident and the detected deployment situation, Emergency Tensioning Devices and/or air bags can supplement the protection offered by a correctly worn seat belt.

When enabled, an air bag can provide additional protection for the respective vehicle occupant.

Potential protection provided by each air bag:

• Knee air bag: thigh, knee and lower leg
• Driver's air bag, front passenger air bag: head and ribcage
  • Window air bag: head
• Side air bag; ribcage, also pelvis for front seat occupants

However, no system available today can completely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and air bag generally do not protect against objects penetrating the vehicle from the outside. It is also not possible to completely rule out the risk of injury caused by the air bag deploying.

Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop

after an accident. Take this into account, particularly if an Emergency Tensioning Device is triggered or an air bag deployed.

If the Emergency Tensioning Devices are triggered or an air bag is deployed, you will hear a bang, and a small amount of powder may also be released:

• The bang will not generally affect your hearing.
- In general, the powder released is not hazardous to health but may cause short-term breathing difficulties to persons suffering from asthma or other pulmonary conditions.
Provided it is safe to do so, leave the vehicle immediately or open the window in order to prevent breathing difficulties.

Air bags and pyrotechnic Emergency Tensioning Devices contain perchlorate material, which may require special handling or environmental protection measures. National guidelines regarding waste disposal must be observed. In California, see the https://dtsc.ca.gov/. Using the search function, you will find information on perchlorate, for example.

Information on the limited protection provided by the restraint system

Risk due to the incorrect behavior of vehicle occupants

All vehicle occupants must make sure of the following in particular:

• They observe the information on the correct seat position ( page 38).
• There are no heavy, sharp-edged or fragile objects in the pockets of their clothing. Store such objects in a suitable place.

WARNING Risk of injury or death due to an incorrect seat position

The seat belt does not offer the intended level of protection if you have not moved the seat backrest to an almost vertical position.

In particular, you could slip beneath the seat-belt and become injured.

Adjust the seat properly before beginning your journey.

▶ Always ensure that the seat backrest is in an almost vertical position and that

the shoulder belt is routed across the center of your shoulder.

Risk due to objects in the vehicle interior

All vehicle occupants must make sure of the following in particular:

• They observe the information on the correct seat position ( page 38).
• There are no objects between the seat, door and door pillar (B-pillar).
• There are no hard objects, e.g. coat hangers, hanging on the grab handles or coat hooks.
• There are no heavy, sharp-edged or fragile objects in the pockets of their clothing. Store such objects in a suitable place.

WARNING Risk of injury or death due to blocked seat belt buckle or seat belt anchorage

Objects next to the front seat that block the seat belt buckle or the moving seat belt anchorage on the front seat impair the function of the Emergency Tensioning Devices.

Before starting the journey, make sure that there are no objects around the seat belt buckle or between the front seat and door.

WARNING Risk of injury from objects in the deployment area of an airbag

Objects in the deployment area of an airbag can hinder or prevent the correct deployment of the airbag.

The airbag may then deploy in an uncontrolled manner and may even cause additional injuries to the vehicle occupants by deploying. This may be the case in particular if the airbag is integrated into the seat.

▶ Always stow and secure objects correctly.

Before commencing your journey, make sure that no objects are stowed in the deployment area of an airbag.

The installation location of an air bag is identified by the AIRBAG ( page 53) symbol.

Risk due to installing accessories

Do not attach accessories such as mobile navigation devices, mobile phones or cup holders within the deployment area of an air bag, e.g. on the cockpit, on the door, on the side window or on the side trim.

In addition, no connecting cables, tensioning straps or retaining straps may be routed or attached to the vehicle within the deployment area of an air bag. Always comply with the accessory manufacturer's installation instructions and, in particular, the notes on suitable places for installation.

WARNING Risk of injury or death due to unsuitable protective covers

Unsuitable protective covers mean that air bags can no longer protect vehicle occupants as they are designed to do.

Use only protective covers approved by Mercedes-Benz for the seat in question.

In addition, the function of the automatic passenger air bag deactivation may be restricted by an unsuitable protective cover. If the front

passenger seat is occupied, ensure that the PASSENGER AIR BAG indicator lamps display the correct status of the front passenger air bag ( page 42).

Risk due to pets in the vehicle interior

WARNING Risk of accident and injury due to animals left unsecured or unattended in the vehicle

If you leave animals in the vehicle unattended or unsecured, they could possibly press buttons or switches.

An animal may:

• Activate vehicle equipment and become trapped, for example
• Switch systems on or off and endanger other road users

Unsecured animals may be thrown around in the vehicle in the event of an accident or sudden steering and braking maneuvers and injure vehicle occupants in the process.

▶ Never leave animals in the vehicle unattended.
Always correctly secure animals while driving, e.g. using a suitable animal carrier.

Important safety notes

Basic information

Be diligent

Bear in mind that negligence when securing a child in the child restraint system may have serious consequences. Always be diligent in securing a child carefully before every journey.

Never allow babies and children to travel sitting on the lap of another vehicle occupant.

To improve protection for children younger than 12 years old or under 5 ft (1.50 m) in height, Mercedes-Benz recommends you observe the following information:

• Always secure the child in a child restraint system suitable for this Mercedes-Benz vehicle.
- The child restraint system must be appropriate to the age, weight and size of the child.
- The vehicle seat must be suitable for the child restraint system to be installed:

Accident statistics show that children secured on the rear seats are generally safer than children secured on the front seats. For this reason,

Mercedes-Benz strongly advises that you install a child restraint system on a rear seat.

The generic term "child restraint system"

The generic term "child restraint system" is used in this Operator's Manual. A child restraint system is, for example:

• a baby car seat
  • a rearward-facing child seat
  • a forward-facing child seat
• a child booster seat – Mercedes-Benz recommends using a child booster seat with a back-rest and seat belt guide.

Observe laws and legal requirements

Always observe the legal requirements when using a child restraint system in the vehicle.

Securing systems for child restraint systems in the vehicle

Use only the following securing systems for child restraint systems:

• the LATCH-type (ISOFIX) securing rings
• the vehicle's seat belt system

• the Top Tether anchorages

Simply attaching to the LATCH-type (ISOFIX) securing rings on the vehicle can reduce the risk of installing the child restraint system incorrectly. When securing a child with the integrated seat belt of the ISOFIX/LATCH child restraint system, always comply with the permissible gross weight for the child and child restraint system ( page 64).

A child booster seat may be necessary to achieve proper seat belt positioning for children over 40 lbs (18 kg) in weight or until they reach a height at which they can wear a three-point seat belt properly without a child booster seat.

Mercedes-Benz recommends a suitable child booster seat with a backrest and seat belt guide.

Observe standards for child restraint systems

All child restraint systems must meet the following standards:

• U.S. Federal Motor Vehicle Safety Standards 213
• Canadian Motor Vehicle Safety Standards 213

Confirmation that the child restraint system complies with the standards can be found on an instruction label on the child restraint system. This confirmation can also be found in the installation instructions that are included with the child restraint system.

Important warning notices

Always secure a child restraint system correctly

WARNING Risk of injury or death due to incorrect installation of the child restraint system

The child can then not be protected or restrained as intended.

Be sure to comply with the manufacturer's installation instructions for the child restraint system and its correct use.

Always comply with the manufacturer's installation instructions for the child restraint system and its correct use.
Always fit child restraint systems correctly, even if they are transported in the vehicle unused.

Do not modify the child restraint system

WARNING Risk of injury due to modifications to the child restraint system

The child restraint system can no longer function properly. This poses an increased risk of injury.

▶ Never modify a child restraint system.
Only affix accessories which have been specially approved for this child restraint system by the child restraint system's manufacturer.

Only use child restraint systems which are in proper working condition

A

WARNING Risk of injury or death caused by the use of damaged child restraint systems

Child restraint systems or their retaining systems that have been subjected to stress in an accident may not be able to perform their intended protective function.

It may be the case that the child cannot be properly restrained.

▶ Always immediately replace child restraint systems that have been damaged or involved in an accident.
Have the securing systems for the child restraint systems checked at a qualified specialist workshop before installing a child restraint system again.

Avoid direct sunlight

A

WARNING Risk of burns when the child seat is exposed to direct sunlight

If the child restraint system is exposed to direct sunlight or heat, parts could heat up excessively.

Children could suffer burns from these parts, particularly the metallic parts of the child restraint system.

Always make sure that the child restraint system is not exposed to direct sunlight.
▶ Cover the child restraint system with a blanket, for example.
If the child restraint system has been exposed to direct sunlight, allow it to cool before securing a child into it.
▶ Never leave children unattended in the vehicle.

- If the high-voltage battery is sufficiently charged, the vehicle can be started with the electric drive system without the combustion engine (noiseless start).

• If the high-voltage battery for the electric drive system is not sufficiently charged or the vehicle conditions for a silent start are not met, the vehicle will start with the combustion engine.
  Depending on the system, it may happen that even though the high-voltage battery is charged, electric mode has restricted or no availability. Once the combustion engine has been operated for long enough and ambient conditions permit, electric mode is again available without restriction.

Characteristics with moderate power output requests:

• The combustion engine is switched off as often as possible during the journey.
• The vehicle can, depending on the drive program selected and the state of charge of the high-voltage battery, be accelerated electrically up to a speed of approximately 87 mph (140 km/h).

Characteristics with high power output requests:

• The electric motor supports the combustion engine (boost effect), e.g. when you pull away or accelerate.
  • The high-voltage battery is discharging.

Characteristics when the accelerator pedal is released during the journey:

• The electric motor is used as an alternator when in overrun mode and during braking.
  • The high-voltage battery is being charged.

Notes on electric mode:

• Vehicles with hybrid systems generate significantly less noise when stationary and when being driven than vehicles with combustion engines.
• When you are driving in electric mode, the vehicle may not be heard by other road users due to the significantly reduced noise generated when the car is in motion and when at a standstill.

For this reason the vehicle is equipped with a sound generator, which serves as an acoustic

vehicle alerting system (AVAS). This safety device is prescribed by law.

The external noise of the sound generator is perceptible in the vehicle interior when the vehicle is stationary and at low speeds and does not represent a malfunction.

• If not all of the vehicle conditions for electric mode are met, then the combustion engine is switched on.
• Performance restrictions in electric mode are possible due to the operating temperature of the high-voltage battery and drive system, the ambient temperature and aging of the high-voltage battery.
• In electric mode, the maximum output is not permanently available and may drop to the level of continuous output.

Notes on the acoustic vehicle alerting system:

- The sound generator generates a stationary noise and speed-dependent vehicle noise emissions at a speed of up to around 19 mph (30 km/h).

Driving and parking

• This helps other road users, particularly pedestrians and cyclists, to hear your vehicle better.
• When you drive at speeds above 13 mph (20 km/h) the acoustic vehicle alerting system will gradually switch off.

Notes on breaking-in a new vehicle

To preserve the engine during the first 1000 miles (1500 km):

• Drive at varying road speeds and engine speeds.
  • No faster than 85 mph (140 km/h).
• Drive the vehicle in drive program C or E.

- Shift to the next gear up when the needle reaches the last third before the red range on the tachometer at the very latest.

• Do not shift down manually to brake.
• Avoid overstraining the vehicle, e.g. driving at full throttle.
• Do not depress the accelerator pedal past the point of resistance (kickdown).
• Increase the engine speed only gradually and accelerate the vehicle to full speed only after 1000 miles (1500 km).

This also applies when the engine or parts of the drivetrain have been replaced.

176 Driving and parking

Please also observe the following breaking-in notes:

• With certain handling and driving safety systems, the sensors will adjust automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness will be reached only once this teach-in process has concluded.
• Brake pads, brake disks and tires that are either new or have been replaced will achieve optimum braking performance and grip only after several hundred kilometers of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal.

Notes on optimizing acceleration

If all necessary requirements and activation conditions are fulfilled, the best possible acceleration can be achieved from a standstill.

Do not use optimized acceleration on public roads. Individual wheels could spin and you could lose control of the vehicle. There is an increased risk of skidding and/or accident.

Be sure to observe the safety notes and information on ESP ^® (→ page 227).

Pulling away with optimized acceleration

WARNING Risk of skidding and accidents due to the wheels spinning

If you pull away using optimized acceleration, individual wheels can spin and the vehicle can skid.

There is an increased risk of skidding and accidents, especially when ESP® is switched off!

Make sure that there are no persons or obstacles in the vicinity of the vehicle.

Requirements

• the vehicle is run in (→ page 175).
• the vehicle and tires are in good condition.
• the roadway has a high-grip surface.
- the engine and transmission are at normal operating temperature.

NOTE Increased wear due to optimized acceleration

When pulling away with optimized acceleration, all components of the drivetrain are subjected to a very high load.

This can lead to increased component wear.

Do not always pull away with optimized acceleration.

Engage the D drive position ( page 193).
Move the steering wheel to the straight-ahead position.
Select the S drive program (→ page 189).
Deactivating ESP ^® (→ page 228).
Depress and hold the brake pedal firmly with your left foot.
With your right foot, fully depress the accelerator pedal.

After no more than five seconds, take your left foot quickly off the brake, but keep the accelerator pedal depressed.
The vehicle will pull away at maximum acceleration.
Switch on ESP ^® once the acceleration procedure is complete.

Ending optimized acceleration

Remove your foot from the accelerator pedal.
Reactivate ESP®.
① After you pull away with optimized acceleration, components of the drivetrain can become very hot, which means that optimized acceleration values may only be reached again after a few minutes.

Notes on driving

WARNING Risk of accident due to objects in the driver's footwell

Objects in the driver's footwell may impede pedal travel or block a depressed pedal.

This jeopardizes the operating and road safety of the vehicle.

Stow all objects in the vehicle securely so that they cannot get into the driver's footwell.
▶ Always install the floor mats securely and as prescribed in order to ensure that there is always sufficient room for the pedals.
Do not use loose floor mats and do not place floor mats on top of one another.

⚠ WARNING Risk of accident due to incorrect footwear

Incorrect footwear includes, for example:

• Shoes with platform soles
• Shoes with high heels
- Slippers
There is a risk of an accident.
Always wear suitable footwear so that you can operate the pedals safely.

WARNING Risk of accident if the vehicle is switched off while driving

If you switch off the vehicle while driving, safety functions are restricted or no longer available.

This may affect the power steering system and the brake force boosting, for example.

You will need to use considerably more force to steer and brake, for example.

Do not switch off the vehicle while driving.

DANGER Risk of death caused by exhaust gases

Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling these exhaust gases is hazardous to health and leads to poisoning.

▶ Never leave the engine or, if present, the auxiliary heating running in an enclosed space without sufficient ventilation.

A WARNING Risk of skidding and of an accident due to shifting down on slippery road surfaces

If you shift down on slippery road surfaces to increase the engine braking effect, the drive wheels may lose traction.

Do not shift down on slippery road surfaces to increase the engine braking effect.

DANGER Risk of fatal injury due to poisonous exhaust gases

If the tailpipe is blocked or sufficient ventilation is not possible, poisonous exhaust gases such as carbon monoxide may enter the vehicle. This is the case, for example, if the vehicle gets stuck in the snow.

Keep the tailpipe and the area around the vehicle free from snow when the engine or the stationary heater is running.

Open a window on the side of the vehicle facing away from the wind to ensure an adequate supply of fresh air.

WARNING Risk of accident and injury due to being under the influence of alcohol and drugs while driving

Drinking and driving and/or taking drugs and driving are very dangerous combinations. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment.

The possibility of a serious or even fatal accident are greatly increased when you drink or take drugs and drive.

Do not drink or take drugs and drive or allow anyone to drive who has been drinking or taking drugs.

WARNING Risk of accident due to the brake system overheating

If you leave your foot on the brake pedal when driving, the brake system may overheat.

This increases the braking distance and the brake system can even fail.

▶ Never use the brake pedal as a footrest.

Do not depress the brake pedal and the accelerator pedal at the same time while driving.

NOTE Engine damage due to excessively high engine speeds

The engine will be damaged if you drive with the engine in the overrevving range.

Do not drive with the engine in the over-revving range.

NOTE Wearing out the brake linings by continuously depressing the brake pedal

Do not depress the brake pedal continuously whilst driving.

To use the braking effect of the engine, shift to a lower gear in good time.

NOTE Damage to the drivetrain and engine when pulling away

Do not warm up the engine while the vehicle is stationary. Pull away immediately.

Avoid high engine speeds and driving at full throttle until the engine has reached its operating temperature.

NOTE Damage to the catalytic converter due to non-combusted fuel

The engine is not running smoothly and is mis-firing.

Non-combusted fuel may get into the catalytic converter.

▶ Only depress the accelerator pedal slightly.

Have the cause rectified immediately at a qualified specialist workshop.

NOTE Reduced battery life due to frequent short-distance trips

The 12 V battery may not be sufficiently charged when the vehicle is used only for short-distance trips. This reduces the life of the battery.

▶ Drive longer distances regularly to charge the battery.

NOTE Damage to the vehicle due to not observing the maximum permitted head-room clearance

If the vehicle height is greater than the maximum permitted headroom clearance, the roof and other parts of the vehicle may be damaged.

Observe the signposted headroom clearance.

If the vehicle height is greater than the permitted headroom clearance, do not enter.

Observe the changed vehicle height with add-on roof equipment.

① Please bear in mind that all the speed values stated in this Operator's Manual are approximate and are subject to a certain tolerance.

Notes on driving with a roof load, trailer or fully laden vehicle

When driving with a loaded roof luggage rack or trailer as well as with a fully laden or fully occupied vehicle, the vehicle's driving and steering characteristics change.

You should therefore bear the following in mind:

- Do not exceed the permissible roof load and towing capacity. Also observe the information in the Technical Data.

- Distribute the roof load and the load inside the vehicle evenly, placing heavy objects at the bottom. Also comply with the notes on loading the vehicle ( page 115).

- Drive attentively, and avoid abrupt starts, braking and steering as well as rapid cornering.

Advice on driving on salt-strewn roads

The braking effect is limited on salt-strewn road surfaces.

Therefore, observe the following notes:

• Due to salt build-up on the brake disks and brake pads, the braking distance can increase considerably or result in one-sided braking.
• Maintain a much greater safety distance to the vehicle traveling ahead.

Remove salt build-up as follows:

• Brake occasionally, paying attention to the traffic conditions
• Carefully depress the brake pedal at the end of the journey and when starting the next journey

Notes on hydroplaning

Hydroplaning can occur if a certain depth of water has built up on the road surface.

Observe the following notes during heavy precipitation or in conditions in which hydroplaning may occur:

- Reduce speed

• Avoid tire ruts
• Avoid sudden steering movements
• Brake carefully
  Also observe the notes on regularly checking wheels and tires ( page 404).

Notes on driving through water on the road

Water ingress can damage the engine, electrics and transmission.

Water can also enter the air intake of the engine and cause engine damage.

Observe the following if you have to drive through water:

• The water, when calm, may reach no higher than the lower edge of the vehicle body.
• Drive at walking pace at most; water may otherwise enter the vehicle interior or engine compartment.
• Vehicles traveling in front or oncoming vehicles can create waves which may exceed the maximum permissible depth of water.

The braking effect of the brakes is reduced after driving through water. Brake carefully, paying

attention to the traffic conditions, until braking effect has been fully restored.

Function of rear axle steering

The rear axle steering is an electromechanical auxiliary steering on the rear axle which adjusts the steering of the rear wheels according to the position of the front wheels, depending on the speed. This results in greater manoeuvrability and improved driving stability, e.g. when cornering. Rear axle steering has the following characteristics:

• reduced steering effort and turning circle resulting in reduced parking effort
• improved driving stability, e.g. when cornering
• more direct steering resulting in improved handling of the vehicle

ECO start/stop function

ECO start/stop function

i Plug-in hybrid: this function is not available.

Depending on the engine, the ECO start/stop function is not available in all drive programs. Observe the status display on the driver's display concerning this.

The engine will be switched off automatically in the following situations if all vehicle conditions for an automatic engine stop are met:

• You brake the vehicle to a standstill in transmission position D or N.
• You depress the brake pedal when traveling at a low speed.

If the system has detected one of the following situations, the engine will not stop:

• You stop at a stop sign and there is no vehicle in front of you.
• The vehicle that stopped in front of you starts up again.
• You maneuver, turn the steering wheel sharply or engage reverse gear.

If the system detects an intelligent stop inhibitor, e.g. a stop sign, the engine will not stop. If you activate the HOLD function or engage the park position [P], the engine can be

switched off in spite of an intelligent stop inhibitor.

The engine will restart automatically in the following cases:

• You engage transmission position D or R.
• You depress the accelerator pedal.
• The vehicle requires an automatic engine start.
  • You release the brake pedal.
• You release the brake pedal on a downhill gradient and the vehicle does not roll.
• The vehicle rolls on a downhill gradient and does not automatically enter glide mode at 15 mph (20 km/h).

ECO start/stop function symbols on the driver's display:

• The Ⓐ symbol (green) appears when the vehicle is at a standstill: the engine was switched off by the ECO start/stop function.

• The symbol (yellow) appears when the vehicle is at a standstill: not all vehicle conditions for an engine stop have been met.

• Neither the Ⓐ symbol nor the Ⓠ symbol appears when the vehicle is at a standstill: an intelligent stop inhibitor, e.g. a stop sign, has been detected.

• The ^0# symbol appears: the ECO start/stop function is deactivated or there is a malfunction.

If the engine was switched off by the ECO start/stop function and you leave the vehicle, a warning tone will sound and the engine will not be restarted. In addition, the following display message will appear on the driver's display:

Vehicle Ready to Drive Switch the Ignition Off Before Exiting

If you do not switch off the vehicle, it will automatically be switched off after three minutes.

Switching the ECO start/stop function on/off

NOTE Mercedes-AMG vehicles

▶ Observe the notes in the Supplement. You could otherwise fail to recognize dangers.

ENGINE START / STOP

Press button ①
A display will appear on the driver's display when you switch the ECO start/stop function on/off.
① will be continuously shown on the driver's display while the ECO start/stop function is deactivated.

ECO display function

ECO Display 1 2 3

The ECO display shows an evaluation of your driving style on the driver's display depending on the situation. This enables you to check the efficiency of your driving style and adjust it if necessary. The ECO Display menu shows a ball that will roll forwards or backwards on a stylized road in the direction of travel according to the driving characteristics.
Above and below the road, lines mark the area for an efficient driving style ③. Ball ② will light up in green if it is rolling within these lines. Outside the lines, the ball will light up in orange.

The ECO display assesses the following criteria for an economical driving style:

• coasting at the right times
- consistent speed
• moderate acceleration

The overall assessment of your driving style "from start" is indicated using stars ①. It starts with five empty stars, which you can fill one after the other if you drive efficiently. When all five stars are filled, a glow will appear in the background.

① You can call up the ECO Display function via the Classic menu ( page 292).

ECO Assist function (vehicles with 48 V on-board electrical system)

For plug-in hybrids, note the ECO Assist information ( page 185).

① ECO Assist is active only in drive programs [E] and [C].

ECO Assist analyzes data for the vehicle's expected route. This allows the system to optimally adjust the driving style for the route ahead, save

fuel and recuperate. If the system detects an event ahead and the vehicle nears the event, ECO Assist will calculate the optimum speed for maximum fuel economy and recuperative energy based on the distance, speed and downhill gradient.

If the deceleration provided by ECO Assist is not sufficient, you must also brake with the service brake. This is especially the case if, for example, you pull away again in slow-moving traffic and the distance to the vehicle in front is very short.

125.3 miles 24967 ① ② #车

① "Foot off the accelerator" recommendation
Route event ahead

If a route event ahead or a vehicle driving in front is detected which requires an adjustment to your driving style to ensure greater efficiency, corresponding symbol ② and the □ symbol (gray) will be displayed.

If you release the accelerator pedal, the symbol will turn green and recuperation in overrun mode will be initiated. If the deceleration is not sufficient, also apply the service brake. If ECO Assist intervenes for a route event ahead (not for a vehicle in front) and you then press the accelerator pedal again, you end ECO Assist's control.

The ECO Assist display is hidden again in the following cases:

• You do not react to the ECO Assist recommendation for a long time.
• You press the accelerator pedal while the ECO Assistant is intervening for a route event ahead (not for a vehicle in front).
  • ECO Assist cannot identify any further recommendations from the route ahead.

In addition to a vehicle in front ☐, ECO Assist can detect the following route events ② depending on the vehicle's equipment:

Traffic circle
S-bend
Sharp bend
T-intersection
Downhill gradient
Speed limit

In drive program C, ECO Assist only reacts to route event "Vehicle in front."

System limits

If the calculated route is adhered to when route guidance is active, ECO Assist will operate with greater accuracy. The basic function is also available without active route guidance. Not all information and traffic situations can be foreseen. The quality depends on the map data.

ECO Assist is only an aid. The driver is responsible for keeping a safe distance from the vehicle in front, for vehicle speed and for braking in good time.

The system may be impaired or may not function in the following situations:

• If there is poor visibility, e.g. due to insufficient illumination of the road, highly variable shade conditions, rain, snow, fog or heavy spray.
• If there is glare, e.g. from oncoming traffic, direct sunlight or reflections.
• If the windshield is dirty in the vicinity of the multifunction camera.
• If the multifunction camera is fogged up, damaged or obscured.
• If road signs are hard to detect, e.g. due to dirt, snow or insufficient lighting, or because they are obscured.
• If the information in the navigation system's digital map is incorrect or out of date.
• If signs are ambiguous, e.g. road signs in road-works or in adjacent lanes.
  • If the radar sensors are dirty or obscured.
• When you drive on roads with steep uphill or downhill gradients.
• If there are narrow vehicles in front, such as bicycles or motorcycles.

Regenerative brake system (plug-in hybrid)

Function of the recuperative brake system

Depending on the selected recuperation level, the electric motor is operated as an alternator when in overrun mode and during braking in order to charge the high-voltage battery while driving. As soon as you take your foot off the accelerator pedal when the vehicle is in motion and in transmission position [D], recuperation in overrun mode is initiated.

The higher the recuperation, the more sharply the vehicle is braked when coasting and the more electrical energy is fed into the high-voltage battery.

The deceleration in overrun mode may not be sufficient depending on the driving conditions. Decelerating to a standstill is not possible. Also brake with the service brake if necessary. Always adapt your speed to the driving conditions and keep a sufficient distance.

The recuperative brake system has the following characteristics:

• supports braking with electronically controlled brake force boosting

• converts the kinetic energy of the vehicle into electric energy
  If you brake hard, the mechanical brake is also used. This means that the maximum recuperative energy cannot be recovered. The more you drive and brake in an anticipatory manner, the more efficiently energy can be recuperated.

System limits

The braking effect of the electric motor during recuperation in overrun mode may be reduced or may not be available at all in the following situations:

• when the high-voltage battery charge level increases
• if the high-voltage battery is not yet at a normal operating temperature

In these cases, the desired deceleration is set by the brake control system.

■ Manually setting recuperative deceleration

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement. You could otherwise fail to recognize dangers.

You can use the steering wheel paddle shifters to adjust the intensity of recuperation in drive programs H, B and EL.

Diagram of a car steering wheel with labeled components 1 and 2, showing dashboard and steering wheel layout.

The following recuperation levels are available:

• D AUTO Intelligent and anticipatory recuperation with ECO Assist ( page 185)

• D + No recuperation: the vehicle rolls freely
• D Normal recuperation
- D - Increased recuperation: strong deceleration in overrun mode, e.g. for driving on downhill gradients

Standard setting:

• D AUTO: if the ECO Assist function is activated in the multimedia system ( page 187).
• D: if the ECO Assist function is deactivated in the multimedia system.

D AUTO is available only if the ECO Assist function is activated in the multimedia system and if the function of the radar sensors is not impaired. Also observe the information on vehicle sensors and cameras ( page 224).

To increase recuperation: briefly pull paddle shifter ①.
To reduce recuperation: briefly pull paddle shifter ②.
Standard setting: pull and hold paddle shifter ① or ②, or engage transmission position D again.

When the vehicle is started again, the standard setting is also set.

The driver's display shows the currently selected recuperation level next to the transmission position display.

ECO Assist (plug-in hybrid)

ECO Assist function

The following function depends on the equipment and the country.

ECO Assist analyzes data for the vehicle's expected route. This allows the system to optimally adjust the driving style for the route ahead, save fuel and recuperate. If the system detects an event ahead and the vehicle nears the event, ECO Assist will calculate the optimum speed for maximum fuel economy and recuperative energy based on the distance, speed and downhill gradient.

If the deceleration provided by ECO Assist is not sufficient, you must also brake with the service brake. This is especially the case if, for example,

you pull away again in slow-moving traffic and the distance to the vehicle in front is very short.

The function will be active in the following circumstances:

• The function is activated in the multimedia system ( page 187).
• The D AUTO recuperation level is selected (→ page 185).
  • M manual gearshifting is not activated.
• Drive program [S] or [icon] is not selected.

① "Foot off the accelerator" recommendation
Route event ahead

If a route event that can be dealt with more efficiently by adjusting your driving style is detected ahead, corresponding symbol ② and the symbol will be displayed in gray.

If you release the accelerator pedal, the symbol will turn green and recuperation in overrun mode will be initiated. If the deceleration is not sufficient, also apply the service brake.

If ECO Assist makes adjustments for a route event ahead and you step on the accelerator pedal, ECO Assist control is terminated. This does not apply in the case of a vehicle in front.

The ECO Assist display is hidden again in the following cases:

• You do not react to the ECO Assist recommendation for a long time.
• You press the accelerator pedal while ECO Assist is intervening for a route event ahead. This does not apply in the case of a vehicle in front.
  • ECO Assist cannot identify any further recommendations from the route ahead.

In addition to a vehicle in front ☐, ECO Assist can detect the following route events ② depending on the vehicle's equipment:

Traffic circle
S-bend
Sharp bend
T-intersection
Downhill gradient
Speed limit

System limits

If the calculated route is adhered to when route guidance is active, ECO Assist will operate with greater accuracy. The basic function is also available without active route guidance. Not all information and traffic situations can be foreseen. The quality depends on the map data.

ECO Assist is only an aid. The driver is responsible for keeping a safe distance from the vehicle in front, for vehicle speed and for braking in good time.

The system may be impaired or may not function in the following situations:

• If there is poor visibility, e.g. due to insufficient illumination of the road, highly variable shade conditions, rain, snow, fog or heavy spray.
• If there is glare, e.g. from oncoming traffic, direct sunlight or reflections.
• If the windshield is dirty in the vicinity of the multifunction camera.
• If the multifunction camera is fogged up, damaged or obscured.
• If road signs are hard to detect, e.g. due to dirt, snow or insufficient lighting, or because they are obscured.
• If the information in the navigation system's digital map is incorrect or out of date.
• If signs are ambiguous, e.g. road signs in road-works or in adjacent lanes.
• If the radar sensors are dirty or obscured.
• When you drive on roads with steep uphill or downhill gradients.
• If there are narrow vehicles in front, such as bicycles or motorcycles.

Glide mode function

NOTE Mercedes-AMG vehicles

▶ Observe the notes in the Supplement. You could otherwise fail to recognize dangers.

With an anticipatory driving style, glide mode helps you to reduce fuel consumption.

Glide mode is characterized by the following:

- The combustion engine is disconnected from the drivetrain and is still running in neutral.

- The transmission position display D is shown in green.

- The combustion engine can be switched off. All of the vehicle functions remain active.

Glide mode will be activated if the following conditions are met:

- Drive program E is selected.

• The speed is within a suitable range.
- The road's course is suitable, e.g. no steep uphill or downhill gradients or tight bends.
- You do not depress the accelerator or brake pedal (except for light brake applications).

Glide mode can also be activated if you have selected the "Eco" setting for the drive in drive program.

Glide mode will be deactivated again if one of the conditions is no longer met.

Glide mode can also be prevented by the following parameters:

• Incline
• Downhill gradient
• Temperature
• Height
• Speed
• Operating status of the engine
• Traffic situation

Function of 4MATIC

4MATIC ensures that all four wheels are driven. Together with ESP® and 4ETS, 4MATIC improves the traction of your vehicle whenever a driven wheel spins due to insufficient traction.

If you fail to adapt your driving style, 4MATIC can neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot take account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible especially for maintaining a safe distance from the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.

① In wintry road conditions, the maximum effect of 4MATIC can be achieved only if you use winter tires (M+S tires), with snow chains if necessary.

Charging the high-voltage battery (plug-in hybrid)

Notes on charging the high-voltage battery

NOTE High-voltage battery damage due to leaving the vehicle idle for lengthy periods of time

Lithium-ion batteries experience a natural self-discharge.

Exhaustive discharging can therefore occur if the vehicle is idle for several months. This can damage the high-voltage battery.

To avoid damage, please observe the following recommendations when handling the high-voltage battery.

NOTE Accelerated aging of the high-voltage battery due to not observing the following recommendations

As a result of its basic characteristics, the storage capacity of and the amount of energy available from the high-voltage battery decreases over the course of its life. Due to this, both the maximum electrical range that can be achieved by the vehicle and its maximum electrical output can be impaired.

The following factors could accelerate the aging of the high-voltage battery:

• A high condition of charge, especially if the vehicle is idle for a lengthy period of time
• Frequent rapid charging with direct current (mode 4)
  • Leaving the vehicle idle for lengthy periods at high ambient temperatures

To avoid accelerated aging, please observe the following recommendations when handling the high-voltage battery.

Recommendations for handling the high-voltage battery:

• Charge the high-voltage battery with direct current (mode 4) only if necessary.
• If leaving the vehicle idle for lengthy periods, park up the vehicle with a high-voltage battery state of charge between 25% and 30%. Do not keep the high-voltage battery continuously connected to power supply equipment.
• If leaving the vehicle idle for lengthy periods of time avoid high ambient temperatures if possible.
• Check the high-voltage battery's state of charge every six weeks (→ page 214).
• Charge the high-voltage battery if the state of charge is below 15%.
• Do not disconnect the 12 V battery even if the vehicle is left idle for a lengthy period. Otherwise, the condition of the vehicle's high-voltage battery cannot be monitored.
• If the high-voltage battery is used only at low states of charge, fully charge the high-voltage battery every six months.

Depending on the equipment, your vehicle is fitted with one of the following vehicle sockets:

• Type 1 for charging with alternating current (mode 2/3)
• Type Combo 1 for charging with alternating current (mode 2/3) and charging with direct current (mode 4)

Diagram of an electric vehicle charging plug with labeled components and a close-up view showing internal wiring.

Example: Combo 1 vehicle socket

① Socket for charging with alternating current
② Socket extension for charging with direct current
When you use a CCS (Combined Charging System) charging cable to charge with direct current, both areas of the vehicle socket will be covered by the charging cable connector.

Charging options for the high-voltage battery (mode 2, 3 or 4):

• Charging through recuperation while the vehicle is in motion

• Charging with alternating current when stationary:

• at a mains socket (mode 2)

• at a wallbox or charging station (mode 3)
  Charging with direct current when stationary:
• at a rapid charging station (mode 4)

Depending on the country-specific vehicle equipment and your vehicle's charging cable, single-phase AC charging is also possible.

Observe the different grid requirements of your current location when charging. Use only charging

cables that conform to the grid requirements. Consult a qualified electrician or your local grid operator if you have any questions.

It is recommended that you charge the high-voltage battery at a wallbox or charging station due to the improved charging performance and better charging efficiency offered.

System limits

The power output of the high-voltage battery may be impaired by the following:

• High or low outside temperatures
- Electrical auxiliary consumers in the vehicle being switched on, e.g. operating the air conditioning system
• Extended periods without charging

The charging time or the charging power of the high-voltage battery may be increased by the following:

• High or low outside temperatures
- A low or high state of charge of the high-voltage battery

- The maximum available charge current of the charging facility

Stowing the charging cable

Always stow the vehicle's charging cable in the charging cable bag provided, and secure the charging cable bag in the trunk or cargo compartment with the included retaining strap. Otherwise, the charging cable bag with the charging cable is not sufficiently secured.

Driving and driving safety systems

Driving systems and your responsibility

Your vehicle is equipped with driving systems that assist you in driving, parking and maneuvering the vehicle. The driving systems are only aids. They are not a substitute for you paying attention to your surroundings and do not relieve you of your responsibility pertaining to road traffic law. The driver is always responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Pay attention to the traffic conditions at all times and intervene when necessary. Be aware of the limitations regarding the safe use of these systems.

Driving systems can neither reduce the risk of an accident if you fail to adapt your driving style nor override the laws of physics. They cannot always take into account road, weather or traffic conditions.

Some driving systems can regulate or limit the speed to a previously set value. Draw attention to the stored speed when changing drivers.

Information on vehicle sensors and cameras

Some driving and driving safety systems use cameras as well as radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle.

WARNING Risk of accident due to restricted detection performance of vehicle sensors and cameras

If the area around vehicle sensors or cameras is covered, damaged or dirty, certain driving and safety systems cannot function correctly. There is a risk of an accident.

Keep the area around vehicle sensors or cameras clear of any obstructions and clean.
Have damage to the bumper, radiator grille or stone chipping in the area of the front and rear windows repaired at a qualified specialist workshop.

Particularly, keep the areas around the sensors and cameras free of dirt, ice and slush ( page 375). The sensors and cameras must not be covered and the detection ranges around them must be kept free. Do not attach additional license plate bracket, advertisements, stickers, foils or foils to protect against stone chippings in the detection range of the sensors and cameras.

Make sure that there are no overhanging loads protruding into the detection range.

If there is damage to a bumper or the radiator grill, or after an impact, have the function of the sensors checked at a qualified specialist workshop. Have damage or stone chipping in the area of the cameras on the front and rear windows repaired at a qualified specialist workshop.

The rear view camera can extend and retract automatically for the purpose of calibration, even though there is no camera image in the display.

Function of ABS

The Anti-lock Brake System (ABS) regulates the brake pressure in critical driving situations:

• During braking, for instance, at maximum full-stop braking or if there is insufficient tire traction, the wheels are prevented from locking.
  • Vehicle steerability while braking is ensured.

If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions and can serve as a reminder to take extra care while driving.

System limits

• ABS is active from speeds of approx. 3 mph (5 km/h).
- ABS may be impaired or may not function if a malfunction has occurred and the yellow ABS warning lamp lights up continuously after the vehicle is started.

Function of BAS

WARNING Risk of an accident caused by a malfunction in BAS (Brake Assist System)

If BAS is malfunctioning, the braking distance in an emergency braking situation is increased.

▶ Depress the brake pedal with full force in emergency braking situations. ABS prevents the wheels from locking.

The Brake Assist System (BAS) supports your emergency braking situation with additional brake force.

If you depress the brake pedal quickly, BAS is activated:

• BAS automatically boosts the brake pressure.
• BAS can shorten the braking distance.
• ABS prevents the wheels from locking.

The brakes will function as usual once you release the brake pedal. BAS is deactivated.

Function of ESP®

WARNING Risk of skidding if ESP ^® is deactivated

If you deactivate ESP ^® , ESP ^® cannot carry out vehicle stabilization.

▶ ESP ^® should only be deactivated in the following situations.

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement. You could otherwise fail to recognize dangers.

The Electronic Stability Program (ESP ^® ) can monitor and improve driving stability and traction in the following situations within physical limits:

• When pulling away on wet or slippery roads.
• When braking.

If the vehicle deviates from the direction desired by the driver, ESP ^® can stabilize the vehicle by intervening in the following ways:

• One or more wheels are braked.
- The engine output is adapted according to the situation.

When ESP ^36 is deactivated, the □OFF warning lamp lights up continuously:

• Driving stability will no longer be improved.
  • The drive wheels could spin.
  • ETS/4ETS traction control is still active.

① When ESP ^ is deactivated, you are still assisted by ESP ^ when braking.

When the warning lamp flashes, one or several wheels has reached its grip limit:

• Adapt your driving style to suit the current
road and weather conditions.
- Do not deactivate ESP®.
- Only depress the accelerator pedal as far as is necessary when pulling away.

Deactivate ESP ^90 in the following situations to improve traction:

• When using snow chains.
• In deep snow.
• On sand or gravel.

① Spinning the wheels results in a cutting action, which enhances traction.

If the warning lamp lights up continuously, ESP® is not available due to a malfunction.

Observe the following information:

• Warning and indicator lamps (→ page 522)

• Display messages (→ page 447)

ETS/4ETS (Electronic Traction System)

ETS/4ETS traction control is part of ESP ^® and makes it possible to pull away and accelerate on a slippery road.

ETS/4ETS can improve the vehicle's traction by intervening in the following ways:

- The drive wheels are braked individually if they spin.

- More drive torque is transferred to the wheel or wheels with traction.

Influence of drive programs on ESP®

The drive programs enable ESP ^ to adapt to different weather and road conditions as well as the driver's preferred driving style. Depending on the selected drive program, the appropriate ESP ^ mode will be activated (→ page 189).

Function of ESP® Crosswind Assist

ESP® Crosswind Assist detects sudden gusts of side wind and helps the driver to keep the vehicle in the lane:

• ESP® Crosswind Assist is active at vehicle speeds between approx. 50 mph (80 km/h) and 125 mph (200 km/h) when driving straight ahead or cornering slightly.
• The vehicle is stabilized by means of individual brake application on one side.

Activating/deactivating ESP® (Electronic Stability Program)

Multimedia system:

NOTE Mercedes-AMG vehicles

Select ESP.
Select On or Off.

ESP ^® is deactivated if the ESP ^® OFF warning lamp lights up continuously on the driver's display.

Observe any information on warning lamps and display messages which may be shown on the driver's display.

Function of EBD

Electronic Brakeforce Distribution (EBD) is characterized by the following:

• Monitoring and regulating the brake pressure on the rear wheels.
- Improved driving stability when braking, especially on bends.

Function of STEER CONTROL

STEER CONTROL assists you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization. This steering recommendation is given in the following situations:

• both right wheels or both left wheels are on a wet or slippery road surface when you brake
  • the vehicle starts to skid

System limits

STEER CONTROL may be impaired or may not function in the following situations:

- ESP ^ is deactivated.

• ESP ^® is malfunctioning.
  • The steering is malfunctioning.

If ESP ^ is malfunctioning, you will be assisted further by the electric power steering.

HOLD function

HOLD function

The HOLD function holds the vehicle at a standstill without requiring you to depress the brake pedal, e.g. while waiting in traffic.

The HOLD function is only an aid. The responsibility for the vehicle safely standing still remains with the driver.

System limits

The HOLD function is only intended to provide assistance when driving and is not a sufficient means of safeguarding the vehicle against rolling away when stationary.

- The incline must not be greater than 30%.

Activating/deactivating the HOLD function

WARNING Risk of an accident due to the HOLD function being active when you leave the vehicle

If the vehicle is only braked with the HOLD function it could, in the following situations, roll away:

• If there is a malfunction in the system or in the power supply.
• If the HOLD function is deactivated by depressing the accelerator pedal or brake pedal, e.g. by a vehicle occupant.
  Always secure the vehicle against rolling away before you leave it.

Requirements

• The vehicle is stationary.
- The driver's door is closed or the seat belt on the driver's side is fastened.
- The vehicle has been started or has been automatically switched off by the ECO start/stop function.

• The electric parking brake is released.
- Active Distance Assist DISTRONIC is deactivated.
- The transmission is in position D, R or N.

• The transmission is shifted to position P.
- The vehicle is secured with the electric parking brake.

In the following situations, the vehicle is held by transmission position P and/or by the electric parking brake:

• The seat belt is unfastened and the driver's door is opened.
  • The vehicle is switched off.
• There is a system malfunction.
  • The power supply is insufficient.

In addition, the Brake Immediately message may appear in the driver's display and a horn tone may sound at regular intervals.

Immediately depress the brake pedal firmly until the warning message disappears. The HOLD function is deactivated.
Additionally secure the vehicle against rolling away.

Function of Hill Start Assist

Hill Start Assist holds the vehicle for a short time when you pull away on a hill under the following conditions:

• The transmission is in position D or R.

• The electric parking brake is released.

This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to roll away.

WARNING Risk of accident and injury due to the vehicle rolling away

After a short time, Hill Start Assist no longer holds the vehicle.

Swiftly move your foot from the brake pedal to the accelerator pedal. Do not leave the vehicle when it is being held by Hill Start Assist.

ATTENTION ASSIST

Function of ATTENTION ASSIST

ATTENTION ASSIST assists you on long, monotonous journeys, e.g. on highways and trunk roads. If indicators of fatigue or increasing lapses in concentration on the part of the driver are detected, the system suggests taking a break.

ATTENTION ASSIST is only an aid. It cannot always detect fatigue or lapses in concentration in

time. The system is not a substitute for a well-rested and attentive driver. On long journeys, take regular breaks in good time that allow for adequate recuperation.

You can choose between two settings:

• Standard: normal system sensitivity.

- Sensitive: higher system sensitivity. The driver is warned earlier and the attention level detected by ATTENTION ASSIST is adapted accordingly.

If drowsiness or increasing lapses in concentration are detected, the ATTENTION ASSIST: Take a Break! warning appears in the driver's display. You can acknowledge the message and take a break where necessary. If you do not take a break and ATTENTION ASSIST continues to detect increasing lapses in concentration, you will be warned again after a minimum of 15 minutes.

ATTENTION ASSIST 1

The following information is displayed in the driver's display:

- The length of the journey since the last break - The attention level determined by ATTENTION ASSIST.

The more segments ① of the circle displayed, the higher the detected attention level. Fewer segments ① are displayed in the circle as the attention level decreases.

If ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warning, the System Suspended message appears.

If a warning is given in the driver's display, the multimedia system offers to search for a rest area. You can select a rest area and start navigation to this rest area.

When you restart the vehicle, ATTENTION ASSIST is automatically switched on. The last selected sensitivity level remains stored.

System limits

ATTENTION ASSIST is active in the 37 mph (60 km/h) to 124 mph (200 km/h) speed range. If the system is not available due to an error, the ATTENTION ASSIST warning light is permanently lit on the driver display

Particularly in the following situations, ATTENTION ASSIST only functions in a restricted manner and warnings may be delayed or not occur:

• If you have been driving for less than approximately 30 minutes.
• If the road condition is poor (uneven road surface or potholes).
  • If there is a strong side wind.

• If you adopt a sporty driving style (high cornering speeds or high rates of acceleration).

• If the Steering Assist function of Active Distance Assist DISTRONIC is active.
  • If the clock is set to the incorrect time.

• If you change lanes and vary your speed frequently in active driving situations.
• if ESP ^ is not available

Also observe any information regarding display messages that can be displayed in the driver's display.

The ATTENTION ASSIST drowsiness or alertness assessment is reset and restarted when continuing the journey in the following situations:

- You switch off the vehicle.

- If you unfasten your seat belt and open the driver's door (e.g. to change drivers or take a break).

Speed control cruise control

Function of cruise control

Cruise control regulates the speed to the value selected by the driver.

If you accelerate to overtake, for example, the stored speed is not deleted. If you remove your foot from the accelerator pedal after overtaking, cruise control will resume speed regulation back to the stored speed.

You can store any speed above 15 mph (20 km/h) up to the maximum design speed.

Observe the notes on driving systems and your responsibility; you may otherwise fail to detect dangers ( page 224).

Mercedes-AMG vehicles: cruise control is available up to a maximum speed of 155 mph (250 km/h).

Displays in the driver's display

• (gray): cruise control is selected but not yet active, or temporarily passive.
  • (green): cruise control is active.

A stored speed appears under the 📞 display and is indicated in the speedometer.

System limits

Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out. Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.

Do not use cruise control in the following situations:

• in traffic situations which require frequent changes of speed, e.g. in heavy traffic, on winding roads
• on slippery roads. Accelerating can cause the drive wheels to lose traction and the vehicle could then skid.
• when visibility is poor

Operating cruise control

⚠ WARNING Risk of accident due to stored speed

If you call up the stored speed and this is lower than your current speed, the vehicle decelerates.

▶ Take into account the traffic situation before calling up the stored speed.

Requirements

• Cruise control is selected.
- ESP ^® must be activated, but not intervening.

• The vehicle speed is at least 15 mph (20 km/h).
• The transmission is in position D.

Active Distance Assist DISTRONIC

Function of Active Distance Assist DISTRONIC Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles are detected ahead, the set distance will be maintained, until the vehicle comes to a standstill if necessary. The vehicle will accelerate or brake depending on the distance to the vehicle in front and the set speed. The speed and distance to the vehicle in front are set using the steering wheel and saved.

Available speed range:

• Vehicles without Driving Assistance Package: 15 mph (20 km/h) - 100 mph (160 km/h)

• Vehicles with Driving Assistance Package: 15 mph (20 km/h) - 130 mph (210 km/h)

The adjustable set speed may differ if a speed limitation (e.g. winter tire limit) is stored. Other features of Active Distance Assist DISTRONIC:

• Adjusts the driving style depending on the selected drive program (energy-saving, comfortable or dynamic) ( page 188)
• Initiates acceleration to the stored speed if the turn signal indicator is switched on to change to the overtaking lane
  • Vehicles with Driving Assistance Package:

- Reacts to stationary vehicles detected in urban speed ranges (except bicycles and motorcycles)

- Takes one-sided overtaking restrictions into account on freeways or multi-lane divided highways (country-dependent)

It is possible to set the driving mode of Active Distance Assist DISTRONIC on the DYNAMIC SELECT menu. Depending on which drive program is selected, the handling can be geared towards energy economy, comfort or dynamic performance. The driving style can be permanently set to Comfort or Dynamic ( page 240) on the Active Distance Assist menu.

Vehicles with Active Parking Assist and Driving Assistance Package: if Active Distance Assist DISTRONIC has braked the vehicle to a standstill, it can automatically follow the vehicle in front when it drives off again within 30 seconds if the system detects that the driver is holding the steering wheel. If a critical situation is detected in the surrounding area when the vehicle drives off, such as a person in the path of the vehicle, a visual and audible warning will be given indicating that the driver must now take control of the vehicle. The vehicle will not be accelerated any further.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

• In snow, rain, fog, heavy spray, direct sunlight or highly variable light conditions, or if there is glare.
• The windshield in the area of the camera is dirty, fogged up, damaged or obscured.
• If the radar sensors are dirty or obscured.
• In parking garages or on roads with steep gradients.
• If there are narrow vehicles in front, such as bicycles or motorcycles.

In addition, on slippery roads, braking or accelerating may cause one or several wheels to lose traction and the vehicle could then skid.

Do not use Active Distance Assist DISTRONIC in these situations.

WARNING Risk of accident from acceleration or braking by Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC may accelerate or brake in the following cases, for example:

• If the vehicle pulls away using Active Distance Assist DISTRONIC.
• If the stored speed is called up and is considerably faster or slower than the currently driven speed.
• If Active Distance Assist DISTRONIC no longer detects a vehicle in front or does not react to relevant objects.
  ▶ Always carefully observe the traffic conditions and be ready to brake at all times.
  Take into account the traffic situation before calling up the stored speed.

WARNING Risk of accident due to insufficient deceleration by Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC brakes your vehicle with up to 50% of the possible deceleration. If this deceleration is not sufficient,

Active Distance Assist DISTRONIC alerts you with a visual and acoustic warning.

Adjust your speed and maintain a suitable distance from the vehicle in front.
Brake the vehicle yourself and/or take evasive action.

WARNING Risk of accident if detection function of Active Distance Assist DISTRONIC is impaired

Active Distance Assist DISTRONIC does not react or has a limited reaction:

- when driving on a different lane or when changing lanes

• to pedestrians, animals, bicycles or stationary vehicles, or unexpected obstacles
  • to complex traffic conditions
  • to oncoming vehicles and crossing traffic

As a result, Active Distance Assist DISTRONIC may neither give warnings nor intervene in such situations.

WARNING Risk of an accident due to Active Distance Assist DISTRONIC being active when you leave the driver's seat

If you leave the driver's seat while the vehicle is being braked by Active Distance Assist DISTRONIC only, the vehicle can roll away.

Always deactivate Active Distance Assist DISTRONIC and secure the vehicle to prevent it from rolling away before you leave the driver's seat.

Press CANCR.

If you brake, deactivate ESP ^® or if ESP ^® intervenes, Active Distance Assist DISTRONIC is deactivated.

Function of Active Speed Limit Assist If a change in speed limit is detected and the automatic adoption of speed limits is switched on, this will automatically be adopted as the stored speed ( page 240). Speed limits below 12 mph (20 km/h) will not be adopted.

The vehicle's speed will be adjusted when it is level with the traffic sign at the latest. In the case of signs indicating entry into an urban area, the speed will be adapted according to the speed permitted within the urban area. The speed limit indicator on the driver's display will always be updated when the vehicle is level with the traffic sign.

If you are driving on German freeways and there is no speed limit, the system will uses the speed stored for a stretch of road with no speed limit as the set speed. If you do not alter the stored speed on a stretch of road with no speed limit, the recommended speed of 80 mph (130 km/h) will be adopted.

If you have put Active Distance Assist DISTRONIC into passive mode by pressing the accelerator pedal, only speed limits that are higher than the set speed will be adopted.

The maximum permissible speed does not take the road condition and current weather and traffic conditions into account. Adjust your speed accordingly as and when necessary.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

System limits

The system limits of Traffic Sign Assist apply to the detection of traffic signs ( page 254). Speed limits below 12 mph (20 km/h) will not automatically be adopted by the system as the stored speed. Temporary speed restrictions (e.g. for a certain time or due to weather conditions) cannot be properly detected by the system.

Adjust your speed in these situations.

WARNING Risk of accident due to Active Speed Limit Assist adapting the vehicle's speed

The speed adopted by Active Speed Limit Assist may be too high or incorrect in some individual cases, such as:

• at speed limits below 12 mph (20 km/h)
• in wet conditions or in fog
- when towing a trailer
▶ Ensure that the driven speed complies with traffic regulations.
Adjust the driving speed to suit current traffic and weather conditions.

Function of route-based speed adaptation

When Active Distance Assist DISTRONIC is activated, the vehicle speed will be adapted accordingly to the route events ahead. Depending on the drive program selected, the vehicle negotiates a route event ahead in an energy-saving, comfortable or dynamic manner. When the route event has been passed, the vehicle accelerates again to the stored speed. The set distance to the vehicle in

front, vehicles detected ahead and speed restrictions ahead are taken into account.

Route-based speed adaptation can be activated in the multimedia system ( page 240).

The following route events are taken into account:

• Bends
• Traffic circles
• T-intersections
• Turns and exits
  • Traffic jams ahead (only with Live Traffic)

Also, the speed is reduced if the turn signal indicator is switched on and one of the following situations is detected:

• Turning at intersections
• Driving on slowing-down lanes
• Driving on lanes adjacent to slowing-down lanes

The driver is responsible for choosing the right speed and considering other road users. This applies in particular to intersections, traffic circles

and traffic lights, as route-based speed adaptation does not brake the vehicle to a standstill.

Speed adaptation is canceled in the following cases:

• If the turn signal indicator is switched off before the route event and it is therefore assumed that the route event is not relevant to the driver.
• If the driver depresses the accelerator or brake pedal during the process.

System limits

Route-based speed adaptation does not take right of way regulations into account. The driver is responsible for complying with road traffic regulations and driving at a suitable speed.

In difficult conditions, the speed selection made by the system may not always be suitable. This applies to the following situations, forexample:

• The road's course is not clearly visible
- Narrowing of the road
- Varying maximum permissible speeds in individual lanes, e.g. at toll stations
• Wet road surfaces, snow or ice

In these situations the driver must intervene accordingly.

WARNING Risk of accident in spite of route-based speed adaptation

Route-based speed adaptation can malfunction or be temporarily unavailable in the following situations:

• If the driver does not follow the calculated route
  • If map data is not up-to-date or available
  • In the event of roadworks
  • In bad weather or road conditions
  • If the accelerator pedal is depressed
  • In the event of electronically displayed speed limitations
  Adapt the speed to the traffic situation.

Function of Active Stop-and-Go Assist

Active Stop-and-Go Assist helps you when in traffic jams on multi-lane roads with separate roadways by automatically pulling away within up to 60 seconds and with moderate steering maneuvers. It orients itself using the vehicle in front and lane markings. Active Stop-and-Go Assist automatically maintains a safe distance from the vehicle in front and vehicles cutting in.

Active Stop-and-Go Assist requires you, as the driver, to keep your hands on the steering wheel at all times so that you are able to intervene at any time to correct the course of the vehicle and keep it in lane.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

Active Stop-and-Go Assist activates automatically when all of the following conditions are met:

• You are in a traffic jam on a highway or high-speed major road.
• Active Distance Assist DISTRONIC is activated and active ( page 236).
  • Active Steering Assist is activated and active ( page 243).
• You are traveling no faster than 35 mph (60 km/h).

When Active Stop-and-Go Assist is active the status display appears on the driver's display.

System limits

The system limitations of Active Distance Assist DISTRONIC and Active Steering Assist apply to Active Stop-and-Go Assist ( page 241).

Active Steering Assist

Function of Active Steering Assist

Active Steering Assist is available up to a speed of 130 mph (210 km/h). The system helps you to stay in the center of the lane by means of moderate steering interventions. Depending on the speed at which you are driving, Active Steering Assist uses the vehicles ahead and lane markings as a reference.

Depending on the country, Active Steering Assist can use the surrounding traffic as a reference in the lower speed range. If necessary, Active Steering Assist can then also provide assistance outside the center of the lane.

If the detection of lane markings and vehicles ahead is impaired, Active Steering Assist will switch to passive mode. The system will provide no support in this case.

Permanent status indicator on the driver's display

During the transition from active to passive status, the symbol will be shown as enlarged and flashing. Once the system is passive, the symbol will be shown in grey on the driver's display.

Contact detection

You are required to keep your hands on the steering wheel at all times and be able to intervene at any time to correct the course of the vehicle and keep it in lane. You must expect a change from active to passive mode or vice versa at any time.

Close-up of a car steering wheel with hands, no visible text or symbols on the dashboard or background

If the system detects that the driver has not steered the vehicle for a considerable period of time or has removed both hands from the steering wheel, a visual warning will be given first. Indica-

tor Ⓞ will appear on the driver's display. If the driver still does not steer the vehicle, or gives no confirmation to the system, a warning tone will sound in addition to the visual warning message. If the driver does not react to this warning for a considerable period, an emergency stop will be initiated (→ page 243).

The warning will not be issued or will be stopped as soon as the system detects that the driver has touched the steering wheel.

Touch detection may be limited or may not function if there is no direct contact between hand and steering wheel, e.g. if you are wearing gloves or if there is a steering wheel cover on the steering wheel.

If Active Steering Assist detects that a system limit has been reached, a visual warning will be issued and a warning tone will sound.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

System limits

Active Steering Assist has limited steering torque for lateral guidance. In some cases, the steering intervention will not be sufficient to keep the vehicle in the lane.

The system may be impaired or may not function in the following instances:

• There is poor visibility, e.g. due to snow, rain, fog, heavy spray, greatly varying ambient light or dark shadows on the road.
• There is glare, e.g. from oncoming traffic, direct sunlight or reflections.
  • Insufficient illumination of the road.
• The windshield is dirty, fogged up, damaged or obscured in the vicinity of the camera, e.g. by a sticker.

• No lane markings are present for one lane, or some markings are unclear, or the markings change quickly, such as in a construction area or intersections.

• The lane markings are worn away, dark or covered up, e.g. by dirt or snow.

• The distance to the vehicle in front is too short and thus the lane markings cannot be detected.
  • The road is narrow and winding.
• There are obstacles on the lane or projecting out into the lane, such as object markers.

The system will not provide assistance in the following conditions:

• On very tight bends and when you are turning.
• When you cross intersections.
• At traffic circles or toll stations.
• When you actively change lanes without switching on the turn signal indicator.
• When the tire pressure is too low.

WARNING Risk of accident if Active Steering Assist unexpectedly stops functioning

If the system limits of Active Steering Assist are reached there is no guarantee that the

system will remain active or will keep the vehicle in lane.
▶ Always keep your hands on the steering wheel and observe the traffic carefully.
▶ Always steer the vehicle paying attention to traffic conditions.

⚠ WARNING Risk of accident if Active Steering Assist unexpectedly intervenes

The detection of lane markings and objects may malfunction and cause unexpected steering interventions.

▶ Steer according to traffic conditions.

Function of Active Emergency Stop Assist

Active Emergency Stop Assist monitors the steering wheel and the accelerator and brake pedals. If the system detects a lack of driver activity and the vehicle threatens to leave the lane, a warning can be issued and an emergency stop initiated.

Vehicles without Driving Assistance Package: The system is available from a speed of approx. 37 mph (60 km/h).

Vehicles with Driving Assistance package: If Active Steering Assist is switched off, the system is available from a speed of approx. 37 mph (60 km/h).

If the system detects that the vehicle is threatening to leave the lane, a warning can be issued and an emergency stop initiated.

- The driver does not touch the steering wheel for a longer period of time or no steering

movement can be measured for a longer period of time (depending on the vehicle equipment).

• Neither the accelerator nor the brake pedal is depressed.
  ① Vehicles with Driving Assistance package: if Active Steering Assist is switched on and active, only the steering wheel is monitored by the system. If the driver does not touch the steering wheel for a longer period of time, a warning may be given despite pedal actuation. Also observe the instructions on the contact detection of Active Steering Assist ( page 241).

Active Emergency Stop Assist issues the following warnings in order:

• Display message ① appears in the driver's display.
• In addition to display Ⓐ a warning tone sounds.
• The message Initiating Emergency Stop will appear in the driver's display, a continuous warning tone will sound, the vehicle will no longer accelerate and, if necessary, slight belt tensioning will be produced.
• The vehicle speed is reduced in increments until it is at a standstill. Sharp brake impulses are also produced.
  ① Vehicles with Driving Assistance Package: If Active Distance Assist DISTRONIC is active and the driver unfastens the seat belt and driver's door, an emergency stop can be initiated immediately.

Vehicles with Driving Assistance Package:

Depending on the country, a lane change to the adjacent lane is carried out, if possible. It is possi-

ble only to change across one lane and only into the outer lane, and not onto the hard shoulder.

When automatic braking is initiated, Active Distance Assist DISTRONIC is deactivated. Depending on the country, the hazard warning light system is switched on.

When the vehicle is stationary, the following actions are carried out:

• The vehicle is secured with the electric parking brake.
  • The vehicle is unlocked.
• If possible, an emergency call is placed to the Mercedes-Benz emergency call center.

Before automatic braking is initiated, you can cancel Active Emergency Stop Assist by steering.

You can cancel the intervention by Active Emergency Stop Assist after automatic braking is initiated by one of the following actions:

- Accelerating or braking: the emergency stop is canceled, but the warning message, warning tone and power steering remain active

• Steering: power-assisted steering is canceled, the warning message and warning tone remain active and the vehicle continues to be braked
Active Emergency Stop Assist can initiate an emergency stop a maximum of three times within a driving cycle. After that, Active Steering Assist and Active Emergency Stop Assist are disabled until the vehicle has been restarted.

System limits

For the detection of vehicles and other obstacles, observe the system limits of the following functions:

• Active Distance Assist DISTRONIC ( page 234)
• Active Steering Assist ( page 241)
• Active Lane Change Assist ( page 245)
• Active Brake Assist ( page 249)

Vehicles without Driving Assistance Package:

Active Emergency Stop Assist is inactive in the following cases:

• Active Lane Keeping Assist has reached a system limit.
- Active Lane Keeping Assist is not operational (gray status display) or deactivated (white status display) (→ page 262).

Active Lane Change Assist

Function of Active Lane Change Assist

Active Lane Change Assist helps the driver when changing lanes and is activated when the driver indicates briefly.

This requires the following conditions to be fulfilled:

• You are driving on a highway or similar road.
• The vehicle speed is between approximately 40 mph (65 km/h) and 110 mph (180 km/h).
- The adjacent lane is separated by a dashed lane marking.
- No vehicle or obstacle is detected in the adjacent lane.

• Active Lane Change Assist is selected in the multimedia system.
• Active Distance Assist DISTRONIC and Active Steering Assist are switched on and active.

Display on the driver's display in the Assistance menu

Two grayscale images showing a car driving on a highway, with lane markings and no visible text or symbols.

① Green arrow: lane change initiated
2 Red arrow: lane change canceled

When Active Lane Change Assist is available, the display will appear along with green arrows on the driver's display. If the system has been activated but is not currently available, the display will appear along with gray arrows on the driver's display.

If no vehicle or obstacle is detected in the adjacent lane and a lane change is permitted, the lane change will begin after the driver has indicated briefly. The lane change will be shown to the driver with a flashing green arrow next to the steering wheel symbol 📋. Green arrow 🌐 will be displayed in the appropriate adjacent lane in the Assistance menu on the driver's display. The Lane Change to the Left message, for example, will also appear.

If a lane change is not possible immediately after the driver has activated the turn signal indicator because an obstacle has been detected, forexample, the arrow next to the steering wheel symbol will also flash in green and the adjacent lane will continue to be monitored. When the lane becomes clear, a lane change will be carried out and the Lane Change to the Left message, for example, will appear on the driver's display. If the green arrows stop flashing, the lane change must be activated again.

Active Lane Change Assist can be canceled in situations including the following:

• The surrounding conditions change (e.g. detected obstacle).
• The driver steers too sharply or in the opposite direction.
• The driver moves the turn signal indicator in the opposite direction.
  • Active Distance Assist DISTRONIC or Active Steering Assist is deactivated.
• The vehicle cannot make the lane change as planned.

Cancelation of Active Lane Change Assist will be displayed as follows:

• The arrow in the selected direction of travel will turn red.
• A corresponding message will also appear on the driver's display.
• In certain circumstances, a warning tone will sound.

WARNING Risk of accident when changing lane to an occupied adjacent lane

Lane Change Assist cannot always clearly detect if the adjacent lane is free.

The lane change might be initiated although the adjacent lane is not free.

Before changing lanes, make sure that the neighboring lane is free and there is no danger to other road users.
▶ Monitor the lane change.

WARNING Risk of accident if Lane Change Assist unexpectedly stops functioning

If the system limitations for Lane Change Assist have been reached, there is no guarantee that the system will remain active.

Lane Change Assist cannot then assist you by applying steering torque.

▶ Always monitor the lane change and keep your hands on the steering wheel. Observe the traffic conditions and steer and/or brake if necessary.

Automatic Lane Change

Automatic Lane Change is a sub-function of Active Lane Change Assist. It can help the driver in deciding when a lane change is appropriate and in executing it.

WARNING Risk of accident due to incorrectly triggered lane change

The system cannot always clearly recognize all situations in which a lane change is appropriate.

The system can initiate a lane change even though the traffic situation is not suitable or the neighboring lane is not available, not usable or occupied.

▶ Always monitor the traffic situation.
If necessary, cancel the lane change by holding the steering wheel or counter-steering slightly and return the vehicle to its own lane.

You can cancel a lane change initiated by the system at any time by holding the steering wheel or

countersteering slightly and returning the vehicle to its own lane.

For Automatic Lane Change to function, the following conditions must be met:

• The conditions for activating Active Lane Change Assist are fulfilled.
  • Automatic Lane Change is activated in the multimedia system.
• You are driving on a highway in a country where the function is available.
• The road currently being traveled allows lane changes; forexample, there are no tight bends.
  • The vehicle speed is between approximately 40 mph (65 km/h) and 85 mph (140 km/h).

Active Lane Change Assist can initiate an automatic lane change in situations including the following:

• The set desired speed of Active Distance Assist DISTRONIC cannot be achieved due to a slower vehicle in front.

• There is little traffic and the set desired speed of Active Distance Assist DISTRONIC can also be achieved in a slower lane.

• A lane change is necessary in order to follow the set route in the navigation system or the road you are currently driving on. The lane change can take place before the request to do so appears in the navigation system.

• The system detects that the lane you are driving in will end soon.
  • You are in the lane furthest to the right.

In particular, Active Lane Change Assist will not carry out an automatic lane change in the following situations:

• If the vehicle is already in a lane that it should use to follow the set route in the navigation system.
• On some route sections, there will be no lane change to the lanes furthest to the right.
• The system detects that the adjacent lane will end soon.
• If an automatic lane change has been canceled by the driver, no lane change will be initiated in that direction for a certain time.
• If the driver has initiated a lane change in one direction or has actively changed lanes, no

lane change in the opposite direction will be initiated for a certain time.

The same abort conditions apply to Automatic Lane Change as to driver-initiated lane changes with Active Lane Change Assist.

In addition, automatic lane changes can be canceled in the following circumstances in particular:

• The system detects a construction site marked off by traffic cones in the vehicle's lane or in the adjacent lane during the lane change.
• The system detects that the reason for the lane change no longer exists.

Display on the driver's display

When Automatic Lane Change is switched on, the Automatic Lane Change On message will appear. When Automatic Lane Change is available, the display will appear in green instead of the display. If Automatic Lane Change is available but not all conditions for activating the function are currently being met, the A symbols will be grayed out. If the system deems it advisable to change lanes and needs to adjust the vehicle's

speed to do so, the green A will flash on the side to which a lane change is to be made.

When the automatic lane change starts, for example, the Lane Change to the Left message will appear and a warning tone will sound.

When the automatic lane change is canceled, the A on the side to which a lane change should be made will turn red. In addition, further warning messages may appear and another warning tone may sound in certain situations.

System limits

The system limitations of Active Steering Assist apply to Active Lane Change Assist ( page 241).

The system may also be impaired or may not function in the following situations:

• The sensors are damaged, obscured or dirty (→ page 224).
  • The exterior lighting shows a defect.
• The system does not detect a suitable road, such as on tight bends.
  • The vehicle is at a construction site.

The Active Lane Change Assist sensors will adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Lane Change Assist will be unavailable during this teach-in process, and no arrows will be displayed next to the Active Steering Assist symbol [icon].

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

Setting Active Lane Change Assist Multimedia system:

→ Settings → Assistance → Driving → Active Lane Change Assist

▶ Select Active Lane Change Assist.

Choose between the On and Off (Off) setting options.

Choose between the On, Also Automatically and Off (Off) setting options.

The Also Automatically setting option can also be switched on and off on the quick-access menu.

① If Active Steering Assist has been switched off, it will not be possible to operate Active Lane Change Assist.

Active Brake Assist

Function of Active Brake Assist

Active Brake Assist consists of the following functions:

• Collision warning
  • Autonomous braking function
  • Situation-dependent brake force boosting
  • Vehicles with Driving Assistance Package and Active Steering Assist: Evasive Steering Assist
• Vehicles with Driving Assistance Package: Evasive Steering Assist
  • Vehicles with Driving Assistance Package: intersection start-off function

Active Brake Assist can help you to minimize the risk of a collision with vehicles, cyclists or pedestrians or to reduce the effects of such a collision.

If Active Brake Assist has detected a risk of collision, a warning tone sounds and the △ distance warning lamp lights up.

Side-by-side comparison of a car on a road, showing two views with numbered annotations (1 and 2) highlighting the lane and side features.

In the Assistance menu, an insufficient distance to the vehicle in front is displayed in red. If you further reduce the distance, the vehicle in front is also highlighted in red. When the system detects a risk of collision, red radar waves appear in front of the vehicle.

① Vehicles with PRE-SAFE®: depending on the country, an additional haptic warning occurs in the form of slight, repeated tensioning of the seat belt.

① Vehicles with active ambient lighting: if Warning Support is activated, the Active Brake Assist warning is also accompanied by ambient lighting ( page 147).

If you do not react to the warning, autonomous braking can be initiated in critical situations. In particularly critical situations, Active Brake Assist can also initiate autonomous braking directly. In this case, the warning tone and the distance warning lamp will occur at the same time as the brake application.

If you apply the brakes yourself in a critical situation or apply the brake during autonomous braking, situation-dependent brake force boosting will occur. The brake pressure increases up to maximum full-stop braking if necessary.

Camera navigation screen showing a car with signal waves and a numbered indicator '1' at the top.

If autonomous braking or situation-dependent brake force boosting has occurred, pop-up ⓚ will appear on the driver's display and then automatically disappear after a short time.

If the autonomous braking function or situation-dependent brake force boosting is triggered, additional preventive measures for occupant protection (PRE-SAFE ^® ) may also be initiated.

WARNING Risk of an accident caused by limited detection performance of Active Brake Assist

Active Brake Assist cannot always clearly identify objects and complex traffic situations.

In such cases, Active Brake Assist might:

• Give a warning or brake without reason
  • Not give a warning or not brake

Active Brake Assist is only an aid. The driver is responsible for maintaining a sufficiently safe distance to the vehicle in front, vehicle speed and for braking in good time.

Always pay careful attention to the traffic situation; do not rely on Active Brake Assist alone.
Be prepared to brake or swerve if necessary.

If Active Brake Assist is deactivated or the functions are restricted, e.g. due to activation of another driving system, the Active Brake Assist warning lamp will appear on the driver's display.

If the system is unavailable due to dirty or damaged sensors or due to a malfunction, or if the functions are restricted, the Active Brake Assist warning lamp ⚠️! will appear on the driver's display.

Also observe the system limits of Active Brake Assist.

The individual subfunctions are available in the following speed ranges:

Collision warning

Collision warning can assist you in the following situations from approximately 4 mph (7 km/h) with an intermittent warning tone and the distance warning lamp △.

Vehicles without Driving Assistance Package:

• At speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead
• At speeds up to approximately 50 mph (80 km/h) when approaching stationary vehicles, pedestrians walking in the direction of travel and cyclists ahead
• At speeds up to approximately 43 mph (70 km/h) when approaching crossing pedestrians and cyclists
• At speeds up to approximately 37 mph (60 km/h) when approaching stationary pedestrians and cyclists

• At speeds up to approximately 50 mph (80 km/h) when approaching cyclists ahead
• At speeds up to approximately 43 mph (70 km/h) when approaching stationary pedestrians and cyclists

Autonomous braking function

If the vehicle is traveling at speeds above approximately 4 mph (7 km/h), the autonomous braking function may intervene in the following situations:

Vehicles without Driving Assistance Package:

• At speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead
• At speeds up to approximately 50 mph (80 km/h) when approaching cyclists ahead,

pedestrians walking in the direction of travel and stationary vehicles

- At speeds up to approximately 43 mph (70 km/h) when approaching crossing pedestrians and cyclists

Vehicles with Driving Assistance Package:

• At speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead
• At speeds up to approximately 75 mph (120 km/h) when approaching crossing vehicles, pedestrians and cyclists
• At speeds up to approximately 62 mph (100 km/h) when approaching stationary vehicles
• At speeds up to approximately 50 mph (80 km/h) when approaching cyclists ahead
• At speeds up to approximately 43 mph (70 km/h) when approaching stationary pedestrians and cyclists

Situation-dependent brake force boosting If the vehicle is traveling at speeds above approximately 4 mph (7 km/h), situation-dependent

brake force boosting may intervene in the following situations.

Vehicles without Driving Assistance Package:

• At speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead
• At speeds up to approximately 50 mph (80 km/h) when approaching cyclists ahead, pedestrians walking in the direction of travel and stationary vehicles
• At speeds up to approximately 43 mph (70 km/h) when approaching crossing pedestrians and cyclists
• At speeds up to approximately 37 mph (60 km/h) when approaching stationary pedestrians and cyclists

Vehicles with Driving Assistance Package:

• At speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead
• At speeds up to approximately 75 mph (120 km/h) when approaching crossing vehicles, pedestrians and cyclists

Driving and parking

• At speeds up to approximately 62 mph (100 km/h) when approaching stationary vehicles
• At speeds up to approximately 50 mph (80 km/h) when approaching cyclists ahead
• At speeds up to approximately 43 mph (70 km/h) when approaching stationary pedestrians and cyclists

Canceling a brake application of Active Brake Assist

You can cancel a brake application by Active Brake Assist at any time by:

• Fully depressing the accelerator pedal or with kickdown.
  • Releasing the brake pedal.

Active Brake Assist may cancel the brake application when one of the following conditions is fulfilled:

• You maneuver to avoid an obstacle.
  • There is no longer a risk of collision.
• An obstacle is no longer detected in front of your vehicle.

Reaction to oncoming road users (only vehicles with Driving Assistance Package)

Active Brake Assist can also react to detected oncoming road users:

• Reaction up to speeds of approximately 62 mph (100 km/h)
• Warning for oncoming road users via acoustic warning and distance warning lamp
  • Autonomous braking application in order to reduce the severity of an accident

Intersection start-off function (only vehicles with Driving Assistance Package)

7 mph

If a risk of collision with other crossing vehicles is detected when you are pulling away or driving at walking pace, three red arrows pointing in the direction of the crossing road user together with the distance warning lamp will light up in succession on the driver's display. If the situation is particularly critical, the arrows will flash. A warning tone will also sound. If you do not react to the warning in critical situations, acceleration may be restricted or autonomous braking may be initiated. Autonomous braking can also prevent the vehicle from pulling away and hold it at a standstill. In particularly critical situations, Active Brake Assist can also initiate autonomous braking directly. In this case, the distance warning lamp and the warning tone will occur at the same time as the brake application.

If autonomous braking or situation-dependent brake force boosting has occurred, a pop-up will appear on the driver's display and then automatically disappear after a short time.

In the Late setting of Active Brake Assist, the purely visual warning level and the limitation of possible acceleration is deactivated. If the situation is particularly critical, a visual warning can

still be issued, a warning tone can be emitted and autonomous braking may be initiated.

Evasive Steering Assist

WARNING Risk of accident despite Evasive Steering Assist

Evasive Steering Assist cannot always recognize objects or complex traffic situations clearly.

Moreover, the steering support provided by Evasive Steering Assist is not sufficient to avoid a collision.

Always pay careful attention to the traffic situation; do not rely on Evasive Steering Assist alone.
Be prepared to brake or swerve if necessary.
End the support by actively steering in non-critical situations.
▶ Drive at an appropriate speed if there are pedestrians close to the path of your vehicle.

Evasive Steering Assist has the following characteristics:

• Detection of pedestrians, cyclists and vehicles.
- Assistance through power-assisted steering if a swerving maneuver is detected.
- Activation by an abrupt steering movement during a swerving maneuver.
- Assistance during swerving and straightening of the vehicle.
- Reaction from a speed of approximately 12 mph (20 km/h) up to a speed of approximately 68 mph (110 km/h).

The steering support of Evasive Steering Assist can be canceled at any time by counter steering.

System limits

Full system performance is not available for a short time after switching on the vehicle or after driving off. As long as the functions are restricted, the Active Brake Assist warning lamp can also be shown on the driver's display. Depending on the environmental conditions, it may take a

few minutes before full system performance is available.

The system may be impaired or may not function, particularly in the following situations:

• In snow, rain, fog, heavy spray, direct sunlight or greatly varying ambient light, or if there is glare.
• If the sensors are dirty, fogged up, damaged or covered. (→ page 224)
• If the sensors are impaired due to interference from other radar sources, e.g. strong radar reflections in parking garages.
• If a loss of tire pressure or a defective tire has been detected and displayed.
• In complex traffic situations where objects cannot always be clearly identified.
• If pedestrians, cyclists or vehicles move quickly into the sensor detection range.
• If road users are hidden by other objects or are located close to other objects.
• If the typical outline of a pedestrian or cyclist cannot be distinguished from the background.

Driving and parking

• If a pedestrian or cyclist is not detected as such, e.g. due to special clothing or other objects.
• If the driver's seat belt is not fastened.
• On bends with a tight radius.

Traffic Sign Assist

Function of Traffic Sign Assist

The traffic sign assistant detects the traffic signs with the multifunction camera and compares them with the information on the digital road map of the navigation system. It assists you by displaying detected speed limits and overtaking restrictions on the driver display. The maximum permissible speed can also be shown on the head-up display.

The system can issue a warning when you exceed the maximum permissible speed.

In some countries, the system can provide you with further functions and can warn you when you are approaching pedestrian crossings or when you are about to drive past stop signs or red lights unintentionally.

The camera also detects and analyzes traffic signs with a restriction indicated by an additional sign (e.g. in wet weather).

Traffic Sign Assist portrays only selected signs on the driver's display. Actual traffic signs and speed limits have priority over traffic signs and speed limits shown on the driver's display.

Also observe the following information:

• select a speed adapted to the traffic, surroundings and weather conditions
• observe actual traffic signs
• observe applicable traffic rules and regulations

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

Indicators on the driver's display

1 LIMIT 80 2 LIMIT 40 3 80 mph

Permissible speed
② Permissible speed when a restriction applies
3 Additional sign with restriction

The system can show up to two traffic signs on the driver's display simultaneously. The system will always prioritize displaying speed limits. A maximum of one traffic sign with a maximum permissible speed can be shown on the head-up display. If two speed signs are shown on the driver's display, e.g. when restrictions are detected, the value of left-hand speed limit ① will always be transmitted to cruise control or Active Distance

Assist DISTRONIC for adoption and shown on the head-up display.

LIMIT 80

Examples of traffic signs that can be displayed

Traffic Sign Assist can detect and display following traffic signs ⓘ:

• speed limits
  • speed limit end points
  • overtaking restrictions
• play streets
  • recommended speeds

Traffic Sign Assist can detect following additional signs ③ and, if necessary, analyze the relevance of the restrictions using other vehicle sensors:

• in wet weather
  • slippery road surfaces
• in fog
  • temporary restrictions
• exits

- restrictions for car/trailer combinations

Traffic Sign Assist also uses data from the digital street map in the navigation system. When you leave or enter a municipality or change roads, on a freeway exit or on-ramp, for example, or after you turn at an intersection, the indicator on the driver's display can thus be updated without a traffic sign having been detected.

i Regularly update the digital road map of the navigation system to optimize the functioning of Traffic Sign Assist.

Depending on vehicle equipment and country, the system can also display speed restrictions ahead on the driver's display and on the head-up display. The driver's display can also show the distance to

an upcoming lower speed limit. Information from the digital road map of the navigation system is used for this purpose. The Assistance menu can also display a dynamic visualization of the speed limits ahead.

If Traffic Sign Assist cannot determine the currently applicable maximum permissible speed (e.g. due to missing signs), the following indicator will appear on the driver's display:

Traffic Sign Assist is not available in all countries. If the vehicle is in a country where Traffic Sign Assist is not supported, this indicator will be displayed permanently.

If Traffic Sign Assist is temporarily or permanently unavailable due to a technical fault or if the windshield is dirty, the ☑ Traffic Sign Assist warning lamp will appear on the driver's display.

① Please also note the information on the Traffic Sign Assist display messages ( page 447).

Warning when the maximum permissible speed is exceeded

The system can warn you if you unintentionally exceed the maximum permissible speed. Depending on the country, you can specify in the multimedia system by how much the maximum permitted speed may be exceeded before a warning is given. You can switch off the warning or set whether the warning should be visual (with a flashing traffic sign on the driver's display) or visual and audible. The selected setting will be confirmed by an indicator on the driver's display.

1 OFF

① Warning visual only

2 WARNING off

2 OFF

The type, duration and deployment stage of the speed warning as well as the possibility of setting the deployment stage above which the warning is to be triggered are subject to the country-specific legislation of the country of delivery of the vehicle.

Additional functions of Traffic Sign Assist (country-specific)

Warning for no-entry signs: Traffic Sign Assist can warn you if you drive the wrong way down a section of road, such as on freeway on-ramps or one-way streets.

Warning at pedestrian crossings: if you approach pedestrian crossings, provided that pedestrians are in the danger zone or are moving towards it, Traffic Sign Assist can warn you up to a speed of approximately 44 mph (70 km/h).

Warning at stop signs: Traffic Sign Assist can warn you up to a speed of approximately 44 mph (70 km/h) if you are about to drive past a stop sign unintentionally. For this to be possible, the signs must be clear, such as if the system detects more than one stop sign, or a stop sign can be confirmed using the digital navigation map. No

warning can be issued if several different signs are detected.

Warning at red lights: Traffic Sign Assist can warn you up to a speed of approximately 44 mph (70 km/h) if you are about to drive through a red light unintentionally.

The following conditions must be fulfilled:

• Several traffic lights have been detected.
• All traffic lights detected are red.
- At least one of the red traffic lights detected is on the front passenger side beside the vehicle's own lane.
- The traffic lights are in the following sequence (from top to bottom): red, yellow, green.

If the function is available, you can activate or deactivate the warnings at pedestrian crossings, stop signs and red lights on the Traffic Sign Assist menu under Further Warnings ( page 258).

System limits

The system may be impaired or may not function particularly in the following situations:

• If visibility is poor, e.g. due to insufficient illumination of the road, highly variable shade conditions, rain, snow, fog, swirling dust or heavy spray
• If there is glare, e.g. from oncoming traffic, direct sunlight or reflections
• If there is dirt on the windshield in the vicinity of the multifunction camera or if the camera is fogged up, damaged or obscured
• if the traffic signs are difficult to see because, for example, they are dirty, obscured, faded, iced over, damaged, inconveniently positioned, insufficiently illuminated or distorted
  • Active traffic signs with LED displays may not be detected correctly or at all due to technical factors, such as transmission frequency

• If the information on the navigation system's digital map is incorrect, incomplete or out of date

• If the signs, road markings or road layout are ambiguous, e.g. in the case of traffic signs in construction sites, at exits and driveways, in the case of adjacent lanes or parallel roads, in the case of pedestrian crossing markings at traffic lights

• If the signage or road markings do not comply with the standard
• If the signage, road markings or road guidance is country-specific and deviates from the route guidance of the navigation system, e.g. in or after road works
  • After sharp turns and tight bends, when traffic signs are outside the camera's field of vision
• If you overtake vehicles with traffic signs affixed or attached to them

Indicator on the driver's display on the menuAssistance

If a vehicle is detected at speeds above approximately 8 mph (12 km/h) and this vehicle enters the warning range immediately afterwards, the warning lamp on the corresponding outside mirror will light up red. On the Assistance menu, the lamp on outside mirror will also light up red, and the lane in which the vehicle is detected will be hatched out.

If a vehicle is detected in the warning range and you switch on the turn signal in the corresponding direction, a double warning tone will sound once, and the warning lamp will flash red on the corre-

sponding outside mirror. Red radar waves ② will be displayed next to your vehicle on the assistant display.

If the turn signal remains on, the indicator on the outside mirror will flash for all other detected vehicles, but no further warning tone will sound. If you overtake a vehicle quickly, no warning will be given.

① Vehicles with active ambient lighting: when Warning Support is activated, the warning will also be emphasized by ambient lighting ( page 147).

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

⚠ WARNING Risk of accident despite Blind Spot Assist

Blind Spot Assist does not react to vehicles approaching and overtaking you at a greatly different speed.

Blind Spot Assist cannot warn drivers in this situation.

▶ Always pay careful attention to the traffic situation and maintain a safe distance at the side of the vehicle.

WARNING Risk of accident despite Active Blind Spot Assist

Active Blind Spot Assist does not react to the following:

- if you overtake a vehicle too closely so that it is in the blind spot area - if vehicles traveling at a much faster speed approach and then overtake

Active Blind Spot Assist may not give warnings or intervene in such situations.

▶ Always pay careful attention to the traffic situation and maintain a safe distance at the side of the vehicle.

Exit warning

The exit warning is an additional function of Blind Spot Assist and Active Blind Spot Assist and can warn vehicle occupants attempting to leave a stationary vehicle about approaching vehicles.

WARNING Risk of accident despite exit warning

The exit warning neither reacts to stationary objects nor to persons or road users approaching you at a greatly differing speed. The exit warning cannot warn drivers in these situations.

Always pay particular attention to the traffic situation when opening the doors and make sure there is sufficient clearance.

If a vehicle is detected in the monitoring range, the red warning lamp will light up on the corresponding outside mirror.

If a vehicle occupant pulls the door handle on the side of the warning, a warning tone will sound twice and the ambient lighting on the respective door and the warning lamps on the corresponding outside mirror will flash red.

① Vehicles with ambient lighting or active ambient lighting: the Warning Support of the ambient lighting can be activated and deactivated (→ page 147).

① The warning assistance may vary depending on the equipment and settings.

This exit warning is available only when Blind Spot Assist or Active Blind Spot Assist is active.

After the vehicle is switched off, the exit warning will continue to function for a few minutes. If a door is opened when the vehicle is switched off, the exit warning will be active again for a few minutes. When the outside mirror warning lamp flashes three times, the exit warning is no longer available.

The exit warning is only an aid and not a substitute for the attention of vehicle occupants. The responsibility for opening and closing the doors and for leaving the vehicle remains with the vehicle occupants.

System limits

Blind Spot Assist and Active Blind Spot Assist may be limited in the following situations, in particular:

• if there is dirt on the sensors or the sensors are obscured

• in poor visibility, e.g. due to fog, heavy rain or snow

• if there are narrow vehicles, e.g. bicycles or motorbikes
  • if the road has very wide or narrow lanes

• if vehicles are not driving in the middle of their lanes

Warnings may be issued in error if you are driving close to crash barriers or similar continuous lane borders. Always make sure that there is sufficient distance to the side for other traffic or obstacles.

Warnings may be interrupted if you drive alongside long vehicles, such as trucks, for a prolonged time.

Blind Spot Assist and Active Blind Spot Assist will not be operational when reverse gear is engaged.

Additionally, the exit warning may be limited in the following situations:

• when the sensors are covered by adjacent vehicles in narrow parking spaces
• when people approach the vehicle
• in the event of stationary or slow-moving objects

Function of the brake application of Active Blind Spot Assist

① The brake application function is only available for vehicles with a Driving Assistance Package.

If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-correcting brake application will be carried out. This is designed to help you avoid a collision.

The course-correcting brake application is available in the speed range between approximately 20 mph (30 km/h) and approximately 125 mph (200 km/h).

WARNING Risk of accident despite brake application of Active Blind Spot Assist

A course-correcting brake application cannot always prevent a collision.
Always steer, brake or accelerate yourself, especially if Active Blind Spot Assist warns you or makes a course-correcting brake application.

Always maintain a safe distance at the sides.

Active Lane Keeping Assist

■ Function of Active Lane Keeping Assist Active Lane Keeping Assist monitors the area in front of your vehicle by means of the multifunction camera (→ page 224) and can warn you before you leave your lane unintentionally. The system can guide you back into your lane through a course-correcting steering intervention and additionally warns you with vibration pulses in the steering wheel. Active Lane Keeping Assist is available in the speed range between 37 mph (60 km/h) and 124 mph (200 km/h).

The system can intervene in the following situations:

• Active Lane Keeping Assist detects a lane marking.
- One of your front wheels goes over a lane marking.

If you activate the turn signal indicator, a steering intervention does not occur on the corresponding side.

If you leave the lane without activating the turn signal indicator, but danger of a collision with a moving obstacle in your lane is detected, a steering intervention does not occur.

Vehicles with Blind Spot Assist or Driving Assistance Package: if the system detects an obstacle, such as another vehicle in the adjacent lane, a steering intervention will occur regardless of the turn signal indicator.

① Vehicles with active ambient lighting: if Warning Support is activated, the Active Lane Keeping Assist warning is also accompanied by ambient lighting ( page 147).

System limits

In the following situations, a lane-correcting steering intervention may not occur but rather a warning may be given on the steering wheel, depending on the situation:

• You clearly and actively steer, brake or accelerate.
• If a driving safety system intervenes, such as ESP®, Active Brake Assist or Active Blind Spot Assist.
• You have adopted a sporty driving style with high cornering speeds or high rates of acceleration.

The system may be impaired or may not function particularly in the following situations:

- If there is poor visibility, e.g. due to insufficient illumination of the road, highly variable shade conditions, rain, snow, fog or heavy spray.

• If there is glare, e.g. from oncoming traffic, the sun or reflections.
• If there is dirt on the windshield in the vicinity of the multifunction camera or if the camera is fogged up, damaged or obscured.
• If there is dirt on the bumper in the area of the radar sensors, or if they are damaged or covered.
• If there are no lane markings, or several unclear lane markings are present for one lane, e.g. around roadworks.
• If the lane markings are worn, dark or covered.
• If the distance to the vehicle in front is too short and thus the lane markings are not detected.
• If the lane markings change quickly, e.g. lanes branch off, cross one another or merge.
  • If the road is very narrow and winding.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers ( page 224).

Function of the rear axle level control system

The rear axle level control system is only available for plug-in hybrids.

⚠ WARNING Risk of becoming trapped due to the vehicle lowering

Vehicles with rear axle level control system: when you unload luggage or leave the vehicle, the vehicle first rises slightly and then returns to the set level shortly afterwards.

You or anyone else in the vicinity of the wheel arches or the underbody could thus become trapped.

The vehicle can also be lowered after being locked.

When leaving the vehicle, make sure that nobody is in the vicinity of the wheel arches or the underbody.

NOTE Damage caused by vehicle being lowered

Vehicles with rear axle level control: The vehicle can be lowered due to differences in temperature or extended non-operational times. This can cause damage to parts of the body.

When stopping the vehicle and when driving off, make sure that there are no obstacles such as curbs under or in the immediate vicinity of the body.

The rear axle level control system ensures a constant vehicle level on the rear axle, even with a laden vehicle.

The rear axle level control system consists of:

• air suspension on the rear axle
• automatic level control system for load compensation

Parking Assist PARKTRONIC

Function of Parking Assist PARKTRONIC

Parking Assist PARKTRONIC is an electronic parking assistance system which monitors the area surrounding your vehicle and shows you the distance between the vehicle and a detected obstacle visually and audibly.

The passive side impact protection also warns you of obstacles to the side. These must be detected beforehand by the sensors in the front or rear bumper while driving by them. If you steer in the direction of a detected obstacle and there is a risk of a lateral collision, a warning is issued. The passive side impact protection can be activated and deactivated via the multimedia system.

In order for front or rear obstacles to the side to be displayed, the vehicle must first travel a distance of at least half a vehicle length. Once the vehicle has traveled one vehicle length, obstacles on all sides can be shown.

Parking Assist PARKTRONIC is only an aid. It is not a substitute for your attention to the surroundings. Responsibility for safe maneuvering and parking remains with you. Make sure that there are no persons, animals, objects, etc. in the maneuvering area while maneuvering and parking in/exiting parking spaces.

Active Parking Assist

Function of Active Parking Assist

Active Parking Assist is an electronic parking assistance system that uses ultrasound with the assistance of the rear-view camera and 360° camera. When you are driving forwards at up to approximately 22 mph (35 km/h), the system will automatically measure parking spaces on both sides of the vehicle.

Active Parking Assist offers the following functions:

Vehicles with rear-view camera

• Parking in parking spaces parallel to the road
• Backing up into parking spaces perpendicular to the road

Vehicles with 360° camera

• Parking in parking spaces parallel to the road
• Parking in parking spaces perpendicular to the road (optionally either forwards or reverse)
• Parking in parking spaces that can be detected as such only due to markings (e.g. at the roadside)
• Exiting parking spaces if you have parked using Active Parking Assist

Active Parking Assist is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe maneuvering and parking remains with you. Make sure that no persons, animals or objects etc. are in the maneuvering area. If Active Parking Assist is available, the indicator will appear on the driver's display. When the system detects parking spaces, will appear. The arrows show on which side of the road availa-

ble parking spaces are located. These will then be shown on the central display.

When Active Parking Assist is activated, the turn signals will be activated based on the calculated path of your vehicle. When you are entering or exiting a parking space, the procedure will be assisted by acceleration, braking, steering and gear changes.

To start the parking procedure, press the button (→ page 280).

Active Parking Assist will be canceled in the following situations:

• You press the button again.
• You begin steering.
• You engage park position P.
• ESP® intervenes.
• You open the driver's door.

System limits

Also observe the system limits of the following systems:

• Rear-view camera (→ page 266)

- 360^ camera ( page 269)

Objects that are above or below the detection range of Active Parking Assist, e.g. protruding loads, overhangs or loading ramps of trucks or boundaries of parking spaces, will not be detected during measurement of the parking space. They will then also not be taken into account when the parking procedure is being calculated. In some circumstances, Active Parking Assist may therefore guide you into the parking space prematurely or brake too late.

Certain ambient conditions, such as snowfall or heavy rain, may lead to a parking space being measured inaccurately. Parking spaces that are partially occupied by trailer drawbars may not be identified as such or may be measured incorrectly. Use Active Parking Assist only on level, high-grip ground.

WARNING Risk of accident due to objects located above or below the detection range of Active Parking Assist

If there are objects above or below the detection range, the following situations may arise:

• Active Parking Assist may steer too early.
- The vehicle may not stop in front of these objects.

There is a danger of collision!

In these situations, do not use Active Parking Assist.

Active Parking Assist can also display unsuitable parking spaces, e.g. parking spaces in which parking is not permitted or parking spaces on unsuitable surfaces.

Do not use Active Parking Assist in the following situations:

• In extreme weather conditions such as ice, packed snow or heavy rain.
• When you are transporting a load that protrudes beyond the vehicle.

• If the parking space is on a steep gradient.
- When snow chains are installed.
- Directly after a tire change or when spare tires are installed.
- If the tire pressure is too low or too high.
- If the suspension is out of alignment, e.g. after bottoming out on a curb.
- On steep inclines of more than approximately 15%.

Overview of software updates

Important software updates may be necessary for the security of your multimedia system's data. Install these updates, or else the security of your multimedia system cannot be ensured.

The multimedia system displays a corresponding message when a software update is available.

If the Automatic Online Update option is active, software updates are downloaded automatically. If the option is deactivated, you will be informed of new software updates once. The software updates are available for downloading for a limited period of time.

Carrying out a software update:

• You can start software updates via the communication module.
• You can start software updates via a Wi-Fi hotspot.
• You can start map updates from an external medium.

i Online software updates cannot be performed via external Wi-Fi hotspots that are encrypted via TKIP.
If the Wi-Fi hotspot requires logging in via the browser, once the connection is successfully established the browser will open in order to start the update. Follow the instructions in the browser in order to start the download.
To complete software updates via the communication module, the vehicle must be connected with the Internet and a Mercedes me user account.
To complete software updates via Wi-Fi, the vehicle must be connected to an external Wi-Fi hotspot.

A software update consists of three steps:

• Downloading or copying of the data required for installation
  • Installation of the downloaded software update
• Activation of the downloaded software update

① It may be necessary to restart the MBUX multimedia system after completion of a software update.
While some software updates are being downloaded, the multimedia system cannot be operated and the vehicle functions may be restricted.
Some software updates require a safe vehicle status for the installation to be completed. They can only be carried out in a safely parked vehicle with the vehicle switched off.

For software updates requiring a safe vehicle status: when the last installation step is reached, a message appears on the central display after the vehicle is switched off. Follow the step-by-step instructions on the central display to complete the installation.

There are software updates that can only be installed when the vehicle is safely parked, there are no more people in the vehicle and the vehicle is locked.

Overview of the toll system

The toll system is optional equipment and is not available in all vehicles.

Debiting of toll charges at freeway toll gates is facilitated with an electronic payment system.

The toll system uses RFID (Radio Frequency Identification) for data transfer between the control unit and the toll station.

The toll system is initially switched off at the factory.

The control unit is in the vehicle glove box.

In order to be able to use the toll system, it must have been registered by the customer and activated by the service provider:

• Activate the toll system in the settings of the MBUX multimedia system or on the control unit.
  • There are two ways to register and activate:
  In the Mercedes me App, register the unit identification number of the control unit and activate the toll system.

- Alternatively, you can register and activate via the Toll Service app.

Activation of the toll system can take up to 48 hours after registration.

When the toll system is activated, the automatic detection of the number of vehicle occupants is initially switched off at the factory. The number of vehicle occupants is preset with one person. The following applies for roads on which toll charges are dependent on the number of vehicle occupants:

• If the automatic detection of the number of vehicle occupants is switched off, the number of vehicle occupants must be selected manually. This ensures correct toll accounting.
• The number of vehicle occupants can be transmitted automatically. In the process, the number of seat belts worn is determined. If the number of detected persons does not correspond with the number of persons actually in the vehicle, the number of persons must be manually selected.

The standard setting of one person does not need to be changed for roads which require toll payment regardless of the number of vehicle occupants.

The toll system enables the payment of toll charges in many states of the USA.

In Mexico, for example, the toll system can be registered and activated for journeys to the USA.

Notes on use

• You can only use the toll system once registration and activation are complete.
• Drive at the prescribed vehicle speed in the toll lane.
• Mercedes-Benz recommends operation using the MBUX multimedia system. Alternatively, this can also be done on the control unit in the glove box.
• For safety reasons, entries should be made while the vehicle is stationary.
• For further information, please consult the Mercedes me App or an authorized Mercedes-Benz Center.

Or call 1-800-FOR-MERCedes (in the USA) or 1-800-387-0100 (in Canada).

For information on how to register and activate the toll system, see the Digital Operator's Manual.

Mercedes-Benz emergency call system

Information on the Mercedes-Benz emergency call system

Your vehicle is equipped with the Mercedes-Benz emergency call system ("eCall"). This feature can

help save lives in the event of an accident. eCall in no way replaces assistance provided from dialing 911.

Mercedes-Benz eCall only functions in areas where mobile phone coverage is available from the wireless service providers. Insufficient network coverage from the wireless service providers may result in an emergency call not being transmitted.

eCall is a standard feature in your Mercedes-Benz vehicle. In order to function as intended, the system relies on the transmission of data detailed in the Transmitted Data section that follows.

To disable eCall, a customer must visit an authorized Mercedes-Benz Service department to deactivate the vehicle's communication module.

Deactivation of this module prevents the activation of any and all Mercedes me connect services. After the deactivation of eCall, automatic emergency call and manual emergency call will not be available.

The vehicle must be switched on before an automatic emergency call can be made.

① eCall is activated at the factory.

eCall can be deactivated by an authorized Mercedes-Benz dealer. Please note that in the event ownership of the vehicle is transferred to another owner in its deactivated state, eCall will remain deactivated unless the new owner visits an authorized Mercedes-Benz dealership to reactivate the system.

Overview of the Mercedes-Benz emergency call system

eCall can help to reduce the time between an accident and the arrival of emergency services at the site of the accident. It helps locate an accident site in places that are difficult to access. However, even if a vehicle is equipped with eCall, this does not mean the system is ON. As such, eCall does not replace dialing 911 in the event of an accident.

An emergency call can be made automatically or manually.

Only make emergency calls if you or others are in need of rescue. Do not make an emergency call in the event of a breakdown or a similar situation.

Messages on the display

Flat tire

Notes in the event of a flat tire

WARNING Risk of accident due to a flat tire

A flat tire severely affects the driving characteristics as well as the steering and braking of the vehicle.

Tires without run-flat characteristics:

▶ Do not drive with a flat tire.
Change the flat tire immediately with an emergency spare wheel or spare wheel. Alternatively, consult a qualified specialist workshop.

Tires with run-flat characteristics:

▶ Observe the information and warning notes on MOExtended tires (run-flat tires).

In the event of a flat tire, the following options are available depending on your vehicle's equipment:

• Vehicles with MOExtended tires: it is possible to continue the journey for a short period of time. Make sure you observe the notes on MOExtended tires (run-flat tires) (→ page 382).

• Vehicles with a TREFIT kit: you can seal the tire so that it is possible to continue the journey for a short period of time. To do this, use the TREFIT kit (→ page 383).

• Vehicles with Mercedes me connect: you can make a call for breakdown assistance via the overhead control panel in the case of a breakdown (→ page 344).
  • All vehicles: change the wheel ( page 428).

The emergency spare wheel is only available in certain countries.

Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you subsequently mount tires that do not feature run-flat characteristics, e.g. winter tires. A TIREFIT kit may be obtained from a qualified specialist workshop.

Vehicles with a Mercedes-Benz emergency call system that are not equipped with a TREFIT kit: in the event of a flat tire, contact the Customer Assistance Center for the Mercedes-Benz emergency call system.

Notes on MOExtended tires (run-flat tires)

WARNING Risk of accident when driving in limp-home mode

When driving in emergency mode the handling characteristics are impaired.

Do not exceed the specified maximum speed of the MOExtended tires.
Avoid any abrupt steering and driving maneuvers as well as driving over obstacles (curbs, pot holes, off-road). This applies, in particular, to a loaded vehicle.
▶ Stop driving in the emergency mode if you notice:

- Banging noise

- Vehicle vibration

- Smoke which smells like rubber

• Continuous ESP ^® intervention

• Cracks in the tire side walls

▶ After driving in emergency mode, have the rims checked by a qualified specialist

workshop with regard to their further use.

The defective tire must be replaced in every case.

With MOExtended tires (run-flat tires), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires. However, the tire affected must not show any clearly visible damage.

You can recognize MOExtended tires by the MOExtended marking which appears on the side wall of the tire.

Vehicles with tire pressure loss warning system: MOExtended tires may only be used in conjunction with an activated tire pressure loss warning system.

Vehicles with tire pressure monitoring system:

MOExtended tires may only be used in conjunction with an activated tire pressure monitoring system.

If a pressure loss warning message appears in the driver's display, proceed as follows:

- Check the tire for damage.

• If driving on, observe the following notes.

Driving distance possible in emergency mode after the pressure loss warning:

Load condition Driving distance possible in emergency mode

Partially laden 50 miles (80 km)

Fully laden 19 miles (30 km)

The driving distance possible in emergency mode may vary depending on the driving style. Observe the maximum permissible speed of 50 mph (80 km/h).

If a tire has gone flat and cannot be replaced with an MOExtended tire, you can use a standard tire as a temporary measure.

Notes on noise or unusual handling characteristics

Make sure there are no vibrations, noises or unusual handling characteristics when the vehicle is in motion. This may indicate that the wheels or tires are damaged. Hidden tire damage could also be causing the unusual handling characteristics.

If you suspect that a tire is defective, reduce your speed immediately and have the tires and wheels checked at a qualified specialist workshop.

Notes on regularly inspecting wheels and tires

WARNING Risk of injury through damaged tires

Damaged tires can cause tire pressure loss.

▶ Check the tires regularly for signs of damage and replace any damaged tires immediately.

WARNING Risk of hydroplaning due to insufficient tire tread

Insufficient tire tread will result in reduced tire grip.

In heavy rain or slush the risk of hydroplaning is increased, in particular where speed is not adapted to suit the conditions.

Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires.

Minimum tread depth for:

• Summer tires: 18 in (3 mm)
• M+S tires: 16 in (4 mm)
For safety reasons, replace the tires before the legally-prescribed limit for the minimum tread depth is reached.

Carry out the following checks on all wheels regularly, at least once a month or as required, for example, prior to a long journey or driving off-road:

- Check the tire pressure (→ page 405).

• Visually inspect wheels and tires for damage.
- Check the valve caps.
- Visually inspect the tire tread depth and the tire contact surface across the entire width. The minimum tread depth for summer tires is 18 in (3 mm) and for winter tires 16 in (4 mm).

Six marks show where the bar indicators (arrow) are integrated into the tire tread. They are visible once a tire tread depth of approximately 116 in (1.6 mm) has been reached.

Notes on snow chains

WARNING Risk of accident due to incorrectly installed snow chains

If you have installed snow chains on the front wheels, they may drag against the vehicle body or chassis components.

▶ Never install snow chains on the front wheels.
Only install snow chains on the rear wheels in pairs.

NOTE Damage to components of the vehicle body or chassis due to mounted snow chains

If you mount snow chains to the front wheels of 4MATIC vehicles, you may damage components of the vehicle body or chassis.

▶ Only mount snow chains to the rear wheels of 4MATIC vehicles.

Observe the following notes when using snow chains:

• Snow chains are only permissible for certain wheel/tire combinations. You can obtain information about this from an authorized Mercedes-Benz Service Center.
• For safety reasons, only use snow chains that have been specifically approved for your vehicle by Mercedes-Benz, or snow chains with the same quality standard.
• Comply with the installation instructions of the snow chain manufacturer.
• If snow chains are installed, the maximum permissible speed is 30 mph (50 km/h).
• Vehicles with Active Parking Assist: do not use Active Parking Assist when snow chains are installed.

(i) You can deactivate ESP ^® to pull away (→ page 228). This allows the wheels to spin, achieving an increased driving force.

Tire pressure

Notes on tire pressure

WARNING Risk of accident due to insufficient or excessive tire pressure

Underinflated or overinflated tires pose in particular the following risks:

• The tires can burst.
- The tires can wear excessively and/or unevenly.
- The driving characteristics as well as the steering and braking characteristics may be greatly impaired.

Comply with the recommended tire pressures and check the tire pressure of all tires, including the spare wheel, regularly:

• Monthly

- When the load changes

• Before embarking on a longer journey

• If operating conditions change, e.g. off-road driving
  Adjust the tire pressure, if necessary.

Tire pressure which is too high or too low can:

• Shorten the service life of the tires.
• Cause increased tire damage.
• Adversely affect driving characteristics and thus driving safety, e.g. due to hydroplaning.

WARNING Risk of accident due to too low a tire pressure

Tires with pressure that is too low can overheat and burst as a consequence.
In addition, they also suffer from irregular wear, which can significantly impair the braking properties and the handling characteristics.
▶ Avoid excessively low tire pressure.

Tire pressure which is too low can cause:

- Tire defects as a result of overheating

• Impaired handling characteristics
- Irregular wear
- Increased fuel consumption

WARNING Risk of accident due to too high a tire pressure

Tires with excessively high pressure can burst. In addition, they also suffer from irregular wear, which can significantly impair the braking properties and the handling characteristics.

▶ Avoid excessively high tire pressures.

Tire pressure which is too high can cause:

• Increased braking distance
  • Impaired handling characteristics
• Irregular wear
  • Impaired driving comfort
  • Susceptibility to damage

WARNING Risk of accident due to repeated pressure drop in the tires

The wheels, valves or tires could be damaged. Too low a tire pressure can lead to the tires bursting.

Examine the tires for foreign objects.
▶ Check whether the tire has a puncture or the valve has a leak.
If you are unable to rectify the damage, contact a qualified specialist workshop.

You can find information on the recommended tire pressures for the vehicle's factory-installed tires on the following labels:

• Tire and Loading Information placard on the B-pillar of your vehicle (→ page 412).
• Tire pressure table on the inside of the fuel filler flap (→ page 407).

Observe the maximum tire pressure ( page 418).

Use a suitable pressure gauge to check the tire pressure. The outer appearance of a tire does not

permit any reliable conclusion about the tire pressure.

Only correct tire pressure when the tires are cold. Conditions for cold tires:

• The vehicle has been parked with the tires out of direct sunlight for at least three hours.
• The vehicle has traveled less than 1 mile (1.6 km).

The vehicle's tires heat up when driving. As the temperature of the tires increases, so too does the tire pressure.

Vehicles with a tire pressure monitoring system: you can also see the tire pressure in the driver's display ( page 409).

The tire pressure recommended for increased load/speed in the tire pressure table can affect the ride comfort.

WARNING Risk of accident due to unsuitable accessories on tire valves

If you mount unsuitable accessories onto tire valves, the tire valves may be overloaded and

malfunction, which can cause tire pressure loss.

Only screw standard valve caps or valve caps specifically approved by Mercedes-Benz for your vehicle onto the tire valve.

Tire pressure table

The tire pressure table is on the inside of the fuel filler flap.

(i) The data shown in the images is example data.

COLD TIRE PRESSURE normal load 30 psi 25 psi maximum load 30 psi 42 psi Warm tire up to +4 psi A212-58E-00 15 SINN

The tire pressure table shows the recommended tire pressure for all tires approved for this vehicle. The recommended tire pressures apply for cold tires under various operating conditions, i.e. loading and/or speed of the vehicle.

If one or more tire sizes precede a tire pressure, the following tire pressure information is only valid for those tire sizes and their respective load condition.

The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of passengers and amounts of luggage. The actual number of seats may differ from this.

100 kPa = 1 bar R18 R19 M+S kPa psi kPa psi A213.581 11:05

Some tire pressure tables only show the rim diameter instead of the complete tire size, e.g. R18. The rim diameter is part of the tire size and can be found on the tire side wall ( page 419).

• Tire and Loading Information placard (→ page 412)
  • Maximum tire pressures ( page 418)

Checking the tire pressure manually

Read the tire pressure recommended for the current operating conditions from the tire and loading information placard or the tire pressure table. Observe the notes on tire pressure.
Remove the valve cap of the tire to be checked.
Press the tire pressure gauge securely onto the valve.
Read the tire pressure.
If the tire pressure is lower than the recommended value, increase the tire pressure to the recommended value.
If the tire pressure is higher than the recommended value, release air. To do so, press down the metal pin in the valve, e.g. using the tip of a pen. Then check the tire pressure again using the tire pressure gauge.
Screw the valve cap onto the valve. Further related subjects:

Tire pressure monitoring system

Function of the tire pressure monitor

DANGER Risk of accident due to incorrect tire pressure

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when

the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.

The system uses a tire pressure sensor to check the pressure and temperature of the tires fitted on the vehicle.

The tire pressure and tire temperature appear on the driver's display.

If there is a substantial pressure loss or if the tire temperature is excessive, you will be warned with display messages ( page 514) or the [U] warning lamp on the driver's display ( page 541).

The tire pressure monitor is only an aid. It is the driver's responsibility to set the tire pressure to the recommended cold tire pressure suitable for the operating situation.

In most cases, the tire pressure monitor will automatically update the new reference values after you have changed the tire pressure. You can, however, also update the reference values by restarting the tire pressure monitor manually ( page 410).

System limits

The system may be impaired or may not function particularly in the following situations:

• incorrect reference values were taught in
• sudden pressure loss caused by a foreign object penetrating the tire, for example
• there is a malfunction caused by another radio signal source

The Tire and Loading Information placard shows the following information:

• Maximum number of seats ② according to the maximum number of people permitted to travel in the vehicle.

• Maximum permissible load Ⓤ comprises the gross weight of all vehicle occupants, load and luggage.
- Recommended tire pressures ① for cold tires. The recommended tire pressures are valid for the maximum permissible load and up to the maximum permissible vehicle speed.

Please also note:

• Information on permissible weights and loads on the vehicle identification plate ( page 437).
  • Information on tire pressure in the tire pressure table ( page 407).

Further related subjects:

• Determining the maximum permissible load (→ page 413)
  • Notes on tire pressure ( page 405).

Steps for Determining Correct Load Limit

The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575, pursuant to

the "National Traffic and Motor Vehicle Safety Act of 1966".

(1): Locate the statement "The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's placard.
(2): Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3): Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4): The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1,400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1,400 - 750 (5 x 150) = 650 lbs.)
(5): Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

(6): If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.
① Not all vehicles are permitted to tow a trailer. Towing a trailer is only permitted if a trailer-hitch is installed. Please consult an authorized Mercedes-Benz dealer if you have any questions about towing a trailer with your vehicle.

Even if you have calculated the total load carefully, you should still make sure that the maximum permissible gross weight and the maximum gross axle weight rating of your vehicle are not exceeded. Details can be found on the vehicle identification plate.

Have your loaded vehicle - including driver, occupants and load - weighed on a vehicle weighbridge.

The measured values may not exceed the maximum permissible values stated on the vehicle identification plate.

Calculation example for determining the maximum load

The following table shows examples of how to calculate total and load capacities with varying seating configurations and different numbers and sizes of occupants. The following examples use a maximum load of 1500 lbs (680 kg). This is for

illustration purposes only. Make sure you are using the actual load limit for your vehicle stated on your vehicle's Tire and Loading Information placard ( page 412).

The higher the weight of all the occupants, the smaller the maximum load for luggage.

Step 1

Example 1 Example 2
Combined maximum weight of occupants and load (data from the Tire and Loading Information placard)	1500 lbs (680 kg) 1500 lbs (680 kg)

Step 2

Example 1 Example 2
Number of people in the vehicle (driver and occupants)	5	1
Distribution of the occupants Front: 2	Rear: 3	Front: 1
Weight of occupants Occupant 1: 150 lbs (68 kg)	Occupant 2: 180 lbs (82 kg)Occupant 3: 160 lbs (73 kg)Occupant 4: 140 lbs (63 kg)Occupant 5: 120 lbs (54 kg)	Occupant 1: 200 lbs (91 kg)
Total weight of all occupants 750 lbs (340 kg) 200 lbs (91 kg)

Step 3

Example 1 Example 2
Permissible load (maximum gross vehicle weight rating from the Tire and Loading Information placard minus the gross weight of all occupants)	1500 lbs (680 kg) - 750 lbs (340 kg) = 750 lbs (340 kg)	1500 lbs (680 kg) - 200 lbs (91 kg) = 1300 lbs (589 kg)

Tire Quality Grading

In accordance with the US Department of Transportation's "Uniform tire Quality Grading Standards", tire manufacturers are required to grade their tires on the basis of the following three performance factors:

TREADWEAR 240 TRACTION B TEMPERATURE A

① Tread wear grade
② Traction grade
3 Temperature grade
① The data shown in the illustration is example data.
① The classification is not legally stipulated for Canada, but it is generally stated.

Tread wear grade

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1\1/2) times as

well on the government course as a tire graded 100.

The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction grade

DANGER Risk of accident due to inadequate traction

The traction grade assigned to this tire is based on straight-ahead braking traction tests.

▶ Always adapt your driving style and drive at a speed to suit the prevailing traffic and weather conditions.

NOTE Damage to the drivetrain from wheelspin

Avoid wheelspin.

The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

Temperature grade

WARNING Risk of accident from tire overheating and tire failure

Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possible tire failure.

▶ Observe the recommended tire pressure.
▶ Regularly check the pressure of all the tires.
▶ Adjust the tire pressure, if necessary.

The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained

high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Average weight of the vehicle occupants: the number of vehicle occupants for which the vehicle is designed, multiplied by 150 lb (68 kg).

Uniform Tire Quality Grading Standards: a uniform standard to grade the quality of tires with regard

to tread quality, tire traction and temperature characteristics. The quality grading assessment is made by the manufacturer following specifications from the U.S. government. The quality grade of a tire is printed on the side wall of the tire.

Recommended tire pressure: the recommended tire pressure is the tire pressure specified for the tires mounted on the vehicle at the factory.

The tire and information placard contains the recommended tire pressure for cold tires, the maximum permissible load and the maximum permissible vehicle speed.

The tire pressure table contains the recommended tire pressure for cold tires under various operating conditions, i.e. loading and/or speed of the vehicle.

Increased vehicle weight due to optional equipment: the combined weight of all standard and optional equipment available for the vehicle, regardless of whether it is actually installed on the vehicle or not.

Rim: the part of the wheel on which the tire is installed.

GAWR (Gross Axle Weight Rating): the GAWR is the maximum gross axle weight rating. The actual load on an axle must never exceed the gross axle weight rating. The gross axle weight rating can be found on the vehicle identification plate on the B-pillar on the driver's side.

Speed rating: the speed rating is part of the tire identification. It specifies the speed range for which a tire is approved.

GVW (Gross Vehicle Weight): the gross vehicle weight comprises the weight of the vehicle including fuel, tools, the spare wheel, any accessories installed, occupants, luggage and the trailer noseweight, if applicable. The gross vehicle weight must not exceed the gross vehicle weight rating GVWR as specified on the vehicle identification plate on the B-pillar on the driver's side.

GVWR (Gross Vehicle Weight Rating): the GVWR is the maximum permitted gross weight of the fully laden vehicle (weight of the vehicle including all accessories, occupants, fuel, luggage and the trailer drawbar noseweight if applicable). The gross vehicle weight rating is specified on the vehicle identification plate on the B-pillar on the driver's side.

Maximum weight of the laden vehicle: the maximum weight is the sum of the curb weight of the vehicle, the weight of the accessories, the maximum load and the weight of optional equipment installed at the factory.

Kilopascal (kPa): metric unit for tire pressure. 6.9 kPa corresponds to 1 psi. Another unit for tire pressure is bar. 100 kilopascal (kPa) equals 1 bar. Load index: in addition to the load-bearing index, the load index may also be printed on the side wall of the tire. This specifies the load-bearing capacity of the tire more precisely.

Curb weight: the weight of a vehicle with standard equipment including the maximum capacity of fuel, oil and coolant. It also includes the air conditioning system and optional equipment if these are installed on the vehicle, but does not include passengers or luggage.

Maximum tire load: the maximum tire load is the maximum permissible weight in kilograms or lbs for which a tire is approved.

Notes on selecting, installing and replacing tires

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement. You could otherwise fail to recognize dangers.

WARNING Risk of accident due to incorrect wheel and tire dimensions

If wheels and tires of the wrong size are installed, the service brakes or components in the

brake system and in the wheel suspension may be damaged.

Always replace wheels and tires with ones that fulfill the specifications of the original part.
For wheels, pay attention to the following:
- Designation
- Type
For tires, pay attention to the following:
- Designation
- Manufacturer
- Type

A WARNING Risk of injury through exceeding the specified tire load-bearing capacity or the permissible speed rating

Exceeding the specified tire load rating or the permissible speed rating may lead to tire damage and to the tires bursting.

Therefore, only use tire types and sizes approved for your vehicle model.
▶ Observe the tire load rating and speed rating required for your vehicle.

NOTE Vehicle and tire damage caused by non-approved tire types and sizes

For safety reasons, only use tires, wheels and accessories which have been specially approved by Mercedes-Benz for your vehicle.

These tires are specially adapted to the active safety systems, such as ABS, ESP® and 4MATIC, and marked as follows:

• MO = Mercedes-Benz Original
• MOE = Mercedes-Benz Original Extended (run-flat tires only for certain wheels)
- MO1 = Mercedes-Benz Original (only certain AMG tires)

Otherwise, certain properties, such as handling characteristics, vehicle noise emissions, consumption, etc. could be adversely affected. Furthermore, other tire sizes could result

in the tires rubbing against the body and axle components when loaded. This could result in damage to the tire or the vehicle. Only use tires, wheels and accessories that have been checked and recommended by Mercedes-Benz.

NOTE Risk to driving safety from retrea- ded tires

Retreaded tires are neither tested nor recommended by Mercedes-Benz, since previous damage cannot always be detected on retreaded tires.

For this reason driving safety cannot be guaranteed.

Do not use used tires if you have no information about their previous usage.

NOTE Possible wheel and tire damage when driving over obstacles

Large wheels have a smaller section width. As the section width decreases, the risk of

wheels and tires being damaged when driving over obstacles increases.

Avoid obstacles or drive especially carefully.

▶ Reduce your speed when driving over curbs, speed bumps, manhole covers and potholes.

▶ Avoid particularly high curbs.

! NOTE Possible wheel and tire damage when parking on curbs or in potholes

Parking on curbs or in potholes can damage the wheels and tires.

▶ Only park on as level a surface as possible.

Avoid curbs and potholes when parking.

NOTE Damage to electronic component parts due to the use of tire-installing tools

Vehicles with tire pressure monitoring system: There are electronic component parts in the wheel.

If tire-installing tools are positioned in the area of the valve, the electronic components could be damaged.

▶ Tire-installing tools should not be applied in the area of the valve.

Always have tires change at a qualified specialist workshop.

! NOTE Damage to summer tires at low ambient temperatures

At low ambient temperatures, tears could form when driving with summer tires, causing permanent damage to the tires.

At temperatures below 45 °F (7 °C) use M+S tires.

Accessory parts which are not approved for your vehicle by Mercedes-Benz, or which are not used correctly, can impair the operating safety.

Before purchasing and using non-approved accessories, visit a qualified specialist workshop and inquire about:

- Suitability

- Legal stipulations

• Factory recommendations

⚠ WARNING Risk of accidents with sports tires

The special tire tread in combination with the optimized tire compound means that the risk of skidding or hydroplaning on wet roads is increased.

In addition, the tire grip is greatly reduced at a low outside temperature and tire running temperature.

Switch on ESP® and adapt your driving style accordingly.

Use M+S tires at outside temperatures of less than 45^ F ( 7^ C).

▶ Only use tires suitable for the intended use.

Observe the following when selecting, installing and replacing tires:

• Furthermore, the use of certain tire types in certain regions and areas of operation can be highly beneficial.
- Only use tires and wheels of the same type (summer tires, winter tires, MOExtended tires) and the same make.
- Only install wheels of the same size on one axle (left and right).

It is only permissible to install a different wheel size in the event of a flat tire in order to drive to the specialist workshop.

• Vehicles with a tire pressure monitoring system: all installed wheels must be equipped with functioning sensors for the tire pressure monitoring system.
• At temperatures below 45^ F ( 7^ C) use winter tires or all-season tires marked M+S for all wheels.

Winter tires provide the best possible grip in wintry road conditions.

• For M+S tires, only use tires with the same tread.
• Observe the maximum permissible speed for the M+S tires installed.
  If the tire's maximum speed is below that of the vehicle, this must be indicated by an appropriate label in the driver's field of vision.
• Break in new tires at moderate speeds for the first 60 miles (100 km).
• Replace the tires after six years at the latest, regardless of wear.
• When replacing with tires that do not feature run-flat characteristics: vehicles with MOExtended tires are not equipped with a TREFIT kit at the factory. Equip the vehicle with a TREFIT kit after replacing with tires that do not feature run-flat characteristics, e.g. winter tires.

For more information on wheels and tires, contact a qualified specialist workshop.

Be sure to also observe the following further related subjects:

• Notes on tire pressure (→ page 405)

• Tire and Loading Information placard (→ page 412)
• Tire size designation, load-bearing capacity, speed rating and load index (→ page 419)
• Tire pressure table (→ page 407)
• Notes on the emergency spare wheel (→ page 433)

Notes on rotating wheels

WARNING Risk of injury through different wheel sizes

Rotating the front and rear wheels can severely impair the driving characteristics. The wheel brakes or suspension components may also be damaged.

▶ Rotate front and rear wheels only if the wheels and tires are of the same dimensions.

Observe the instructions and safety notes on "Changing a wheel" (→ page 423)

The wear patterns on the front and rear wheels differ:

• Front wheels wear more on the tire shoulder
• Rear wheels wear more in the center of the tire

Do not drive with tires that have too little tread depth. This significantly reduces traction on wet roads (hydroplaning).

On vehicles that have the same size front and rear wheels, rotate the wheels according to the intervals in the tire manufacturer's warranty book in your vehicle documents. If this is not available, rotate the tires every 3,000 to 6,000 miles (5,000 to 10,000 km), depending on the wear. Ensure that the direction of rotation is maintained.

Notes on storing wheels

When storing wheels, observe the following notes:

• After removing wheels, store them in a cool, dry and preferably dark place.
