Protection of the environment

Mercedes-Benz GLS (2019) - Protection of the environment - 1

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 tyre 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 engine while the vehicle is 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 engine in stationary traffic, e.g. by using the ECO start/stop function.
▶ Drive fuel-efficiently. Observe the ECO display for a fuel-efficient driving style.

Mercedes-Benz GLS (2019) - Personal driving style: - 1

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 faulty high-voltage batteries at a qualified specialist workshop.

Take-back of end-of-life vehicles

EU countries only:

Mercedes-Benz will take back your end-of-life vehicle for environment-friendly disposal in accordance with the European Union (EU) End-of-Life Vehicles Directive.

A network of vehicle take-back points and dismantlers has been established for you to return your vehicle. You can leave it at any of these points free of charge. This makes an important contribution to closing the recycling circle and conserving resources.

For further information about the recycling and disposal of end-of-life vehicles, and the take-

back conditions, please visit the national Mercedes-Benz website for your country.

Mercedes-Benz GenuineParts

Mercedes-Benz GLS (2019) - Mercedes-Benz GenuineParts - 1

ENVIRONMENTAL NOTE Environmental damage caused by not using recycled reconditioned components

Daimler AG offers recycled reconditioned components and parts with the same quality as new parts. The same entitlement from the implied warranty is valid as for new parts.

Use recycled reconditioned components and parts from Daimler AG.

NOTE Impairment of the operating efficiency of the restraint systems from installing accessory parts or from repairs or welding

Airbags and seat belt tensioners, as well as control units and sensors for the restraint systems, may be installed in the following areas of your vehicle:

  • doors
  • door pillars
  • door sills
  • seats
  • cockpit
  • instrument cluster
  • centre console
  • lateral roof frame

Do not install accessory parts such as audio systems in these areas.
Do not carry out repairs or welding.
Have accessories retrofitted at a qualified specialist workshop.

You could jeopardise the operating safety of your vehicle if you use parts, tyres and wheels as well as accessories relevant to safety which have not been approved by Mercedes-Benz. Safety-relevant systems, e.g. the brake system, may malfunction. Only use Mercedes-Benz GenuineParts or parts of equal quality. Only use tyres, wheels and accessories that have been specifically approved for your vehicle model.

Mercedes-Benz tests original parts and conversion parts and accessories that have been specifically approved for your vehicle model for their reliability, safety and suitability. Despite ongoing market research, Mercedes-Benz is unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or independently approved by a testing centre.

Certain parts are only officially approved for installation or modification if they comply with legal requirements. All Mercedes-Benz Genuine-Parts meet the approval requirements. The use of non-approved parts may invalidate the vehicle's general operating permit.

This is the case in the following situations:

  • the vehicle type is different from that for which the vehicle's general operating permit was granted.
  • other road users could be endangered.
    • the exhaust gas or noise level gets worse.

Always specify the vehicle identification number (VIN) ( page 633) when ordering Mercedes-Benz Genuine Parts.

Owner's Manual

This Owner's Manual describes all models and all standard and optional equipment available for your vehicle at the time of this Owner's Manual going to press. Country-specific differences are possible. Note that your vehicle may not be fitted with all features described. This is also the case for systems and functions relevant to safety. Therefore, the equipment on your vehicle may differ from that in the descriptions and illustrations.

The original purchase agreement for your vehicle contains a list of all of the systems in your vehicle.

Should you have any questions concerning equipment and operation, please consult a Mercedes-Benz Service Centre.

The Owner's Manual and Service Booklet are important documents and should be kept in the vehicle.

Operating safety

⚠ WARNING Risk of accident due to malfunctions 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/maintenance work as well any required repairs carried out at a qualified specialist workshop.

A WARNING Risk of accident and injury as a result of incorrect modifications to electronic component parts

Modification to electronic components, their software or wiring could impair their function and/or the function of other networked component parts. In particular, systems relevant to safety could also be affected.

As a result, they may no longer function as intended and/or 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.

If you modify the on-board electronics, the general operating permit is rendered invalid.

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

WARNING Risk of fire due to flammable materials on hot parts of the exhaust system

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 unpaved roads or off-road, regularly check the vehicle underside.
Remove trapped plants or other flammable material, in particular.
If there is damage, consult a qualified specialist workshop immediately.

NOTE Damage to the vehicle

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

- the vehicle becomes grounded, e.g. on a high kerb or an unpaved road

  • the vehicle is driven too fast over an obstacle, e.g. a kerb, speed bump or pot-hole
  • a heavy object strikes the underbody or chassis components

In situations such as this, the body, the underbody, chassis components, wheels or tyres could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, may not absorb the loads that arise as intended.

If the underbody panelling is damaged, flammable materials such as leaves, grass or twigs can collect between the underbody and the underbody panelling. These materials may ignite if they come into contact with hot parts on the exhaust system.

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

or

If driving safety is impaired while continuing your journey, pull over and stop the vehicle immediately in accordance with the traffic conditions, and contact a qualified specialist workshop.

Information on the REACH regulation

EU and EFTA countries only:

The REACH regulation (Regulation (EC) No. 1907/2006, Article 33) stipulates a duty to supply information about substances of very high concern (SVHCs).

Daimler AG acts to the best of its knowledge to prevent these SVHCs from being used and to enable customers to safely handle these substances. There are SVHCs known to Daimler AG, according to supplier information and internal product information, found in individual components of this vehicle in quantities of over 0.1 percent by weight. Further information can be obtained at the following addresses:

  • https://reach.daimler.com/de/home/
  • https://reach.daimler.com/en/home/

Notes for persons with electronic medical aids

Daimler AG cannot, despite carefully developing vehicle systems, completely rule out the interaction of vehicle systems with electronic medical aids such as cardiac pacemakers.

For this reason, the following can occur in isolated cases, depending on the aids used:

  • Aids malfunctioning
  • Adverse health effects

Observe the notes and warnings of the manufacturer of the aids; if in doubt, contact the device manufacturer and your doctor. Daimler AG recommends using only few electrical vehicle systems if there is continuing uncertainty concerning the possibility of aids malfunctioning.

Further information can be obtained at https://www.mercedes-benz.de/qr-code.

Data storage

Electronic control units

Electronic control units are fitted in your vehicle. Some of these are necessary for the safe operation of your vehicle, while some assist you when driving (driver assistance systems). In addition, your vehicle provides comfort and entertainment functions, which are also made possible by electronic control units.

Electronic control units contain data memories which can temporarily or permanently store

technical information about the vehicle's operating state, component loads, maintenance requirements and technical events or faults.

In general, this information documents the state of a component part, a module, a system or surroundings such as:

  • operating status of system components (e.g. fill levels, battery status, tyre pressure)
  • status messages concerning the vehicle or its individual components (e.g. number of wheel revolutions/speed, longitudinal acceleration, lateral acceleration, display of fastened seat belts)
  • malfunctions or faults in important system components (e.g. lights, brakes)
    • information on events leading to vehicle damage
  • system reactions in special driving situations (e.g. airbag deployment, intervention of stability control systems)
  • ambient conditions (e.g. temperature, rain sensor)

In addition to providing the actual control unit function, this data assists the manufacturer in detecting and rectifying faults and optimising vehicle functions. The majority of this data is temporary and is only processed in the vehicle itself. Only a small portion of the data is stored in the event or fault memory.

When your vehicle is serviced, technical data from the vehicle can be read out by service network employees (e.g. workshops, manufacturers) or third parties (e.g. breakdown services). Services include repair services, maintenance processes, warranty claims and quality assurance measures, for example. The read out is performed via the legally prescribed port for the diagnostics connection in the vehicle. The respective service network locations or third parties collect, process and use the data. They document technical statuses of the vehicle, assist in finding faults and improving quality and are transmitted to the manufacturer, if necessary. Furthermore, the manufacturer is subject to product liability. For this, the manufacturer requires technical data from vehicles.

Fault memories in the vehicle can be reset by a service outlet as part of repair or maintenance work.

Depending on the selected equipment, you can import data into vehicle convenience and info-tainment functions yourself.

This includes, for example:

  • multimedia data such as music, films or photos for playback in an integrated multimedia system
  • address book data for use in connection with an integrated hands-free system or an integrated navigation system
  • entered navigation destinations
    • data about the use of internet services

This data can be saved locally in the vehicle or it is located on a device which you have connected to the vehicle (e.g. a smartphone, USB flash drive or MP3 player). If this data is stored in the vehicle, you can delete it at any time. This data is sent to third parties only at your request, particularly when you use online services in accordance with the settings that you have selected.

You can store or change convenience settings/individualisations in the vehicle at any time.

Depending on the equipment, this includes, for example:

  • settings for the seat and steering wheel positions
  • suspension and climate control settings
    • customisations such as interior lighting

If your vehicle is accordingly equipped, you can connect your smartphone or another mobile end device to the vehicle. You can control this by means of the control elements integrated in the vehicle. Images and audio from the smartphone can be output via the multimedia system. Certain information is simultaneously transferred to your smartphone.

Depending on the type of integration, this can include:

  • general vehicle data
  • position data

This allows you to use selected apps on your smartphone, such as navigation or music playback. There is no further interaction between the smartphone and the vehicle; in particular, vehicle data is not directly accessible. Which type further data processing occurs is determined by the provider of the specific app used. Which settings you can make, if any, depends on the specific app and the operating system of your smartphone.

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 enabled via the vehicle's transmission and reception unit or via connected mobile end devices (e.g. smartphones). Online functions can be used via the wireless network connection. This includes online services and applications/apps provided by the manufacturer or other providers.

Manufacturer's services

Regarding online services of the manufacturer, the individual functions are described by the

manufacturer in a suitable place (e.g. Owner's pose of the collection and use of personal data Manual, website of the manufacturer) along with when services are provided by third parties.

the relevant data protection information. Personal data may be used for the provision of online services. Data is exchanged via a secure connection, e.g. the manufacturer's designated IT systems. Personal data is collected, processed and used via the provision of services exclusively on the basis of legal permissions or with prior consent.

The services and functions (sometimes subject to a fee) can usually be activated or deactivated. In some cases, this also applies to the entire vehicle's data connection. This excludes, in particular, legally prescribed functions and services.

Third party services

If it is possible to use online services from other providers, these services are the responsibility of the provider in question and subject to that provider's data protection conditions and terms of use. The manufacturer has no influence on the content exchanged.

Restraint system

Protection provided by the restraint system

The restraint system includes the following components:

  • Seat belt system
  • Airbags
    • Child restraint system
    • Child seat securing systems

The restraint system can help prevent the vehicle occupants from coming into contact with parts of the vehicle interior in the event of an accident. In the event of an accident, the restraint system can also reduce the forces to which the vehicle occupants are subjected.

A seat belt can only provide the best level of protection if it is worn correctly. Depending on the detected accident situation, seat belt tensioners and/or airbags supplement the protection offered by a correctly worn seat belt. Seat belt tensioners and/or airbags are not deployed in every accident.

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

  • Fasten seat belts correctly.
  • Sit in an almost upright seat position with their back against the seat backrest.
  • Sit with their feet resting on the floor, if possible.
  • Always secure persons under 1.50 m tall in an additional restraint system suitable for Mercedes-Benz vehicles.

However, no system available today can completely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and airbag 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 airbag deploying.

Reduced restraint system protection

Mercedes-Benz GLS (2019) - Reduced restraint system protection - 1

WARNING Risk of injury or death from modifications to the restraint system

The restraint system can no longer function correctly after alterations have been made.

The restraint system may then not protect the vehicle occupants as intended by failing in an accident or triggering unexpectedly, for example

▶ Never alter the parts of the restraint system.
▶ Never tamper with the wiring or any electronic component parts or their software.

If it is necessary to modify the vehicle to accommodate a person with disabilities, contact a qualified specialist workshop.

Mercedes-Benz recommends that you use driving aids which have been approved for your vehicle by Mercedes-Benz.

Restraint system functionality

When the ignition 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.

Malfunctioning restraint system

A malfunction has occurred in the restraint system if:

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

Mercedes-Benz GLS (2019) - Malfunctioning restraint system - 1

WARNING Risk of injury due to malfunctions in the restraint system

If the restraint system is malfunctioning, restraint system components may be triggered unintentionally or may not deploy as

intended during an accident. This may affect the seat belt tensioner or airbag, for example.

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

Function of the restraint system in an accident

How the restraint system works is determined by the severity of the impact detected and the type of accident anticipated:

on. Frontal impact

  • Rear impact
  • Side impact
  • Rollover

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 preemptive 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 which can only be seen and measured after a collision has occurred do not play a decisive role in the deployment of an airbag. Nor do they provide an indication of airbag deployment.

The vehicle may be deformed significantly without an airbag 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 airbag may be deployed even though the vehicle suffers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, for example, this may result in sufficiently high levels of vehicle deceleration.

The components of the restraint system can be activated or deployed independently of each other:

Component Detected deployment situation
Seat belt tensionersFrontal impact, rear impact, side impact, rollover
Driver's airbag, front passenger airbagFrontal impact
Knee airbag Frontal impact
Side airbag Side impact
Window airbagSide impact, rollover, frontal impact
Cushionbag Frontal impact
PRE-SAFE® Impulse SideSide impact

The front passenger airbag can only be deployed in an accident if the PASSENGER AIR BAG OFF

indicator lamp is off. If the front passenger seat is occupied, make sure, both before and during the journey, that the status of the front passenger airbag is correct ( page 48).

⚠ WARNING Rick of burns from hot airbag components

The airbag parts are hot after an airbag has been deployed.

▶ Do not touch the airbag parts.
Have a deployed airbag replaced at a qualified specialist workshop as soon as possible.

Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident. Take this into account, particularly if a seat belt tensioner is triggered or an airbag deployed.

If the seat belt tensioners 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.

Seat belts

Protection provided by the seat belt

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

Always observe the instructions about the correct driver's seat position and adjusting the seat ( page 117).

In order for the correctly worn seat belt to provide the intended level of protection, each vehicle occupant must observe the following information:

  • The seat belt must not be twisted and must fit tightly and snugly across the body.
  • The seat belt must be routed across the centre of the shoulder and as low down across the hips as possible.
  • The shoulder section of the seat belt should not touch your neck nor be routed under your arm or behind your back.
  • Avoid wearing bulky clothing, e.g. a winter coat.
  • Push the lap belt down as far as possible across your hips and pull tight with the shoul-

der section of the belt. Never route the lap belt across your abdomen.

Pregnant women must also take particular care with this.

  • Never route the seat belt across sharp, pointed, abrasive or fragile objects.
  • Only one person should use each seat belt any one time. Never allow babies and children to travel sitting on the lap of another vehicle occupant.
  • Never secure objects with a seat belt if the seat belt is also being used by one of the vehicle's occupants. Always observe the instructions for loading the vehicle when securing objects, luggage or loads (→ page 144).
    Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat.

If children are travelling in the vehicle, be sure to observe the instructions and safety notes on

"Children in the vehicle" ( page 53).

Limitations of the protection provided by the seat belt

Mercedes-Benz GLS (2019) - Limitations of the protection provided by the seat belt - 1

WARNING Risk of injury or death due to 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.

When braking or in the event of an accident, you could slide underneath the seat belt and sustain abdominal or neck injuries, for example.

Adjust the seat properly before beginning your journey.
Always ensure that the seat backrest is in an almost vertical position and that the shoulder section of your seat belt is routed across the centre of your shoulder.

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

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

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 secure persons under 1.50 m tall in a suitable restraint system.

WARNING Risk of injury or death due to damaged or modified seat belts

Seat belts cannot provide protection in the following situations:

- the seat belt is damaged, has been modified, is extremely dirty, bleached or dyed

  • the seat belt buckle is damaged or extremely dirty
  • modifications have been made to the seat belt tensioner, seat belt anchorage or seat belt retractor

Seat belts may sustain non-visible damage an accident, e.g. due to glass splinters.

Modified or damaged seat belts could tear fail in the event of an accident, for example.

Modified belt tensioners may be deployed unintentionally or not function as intended.

▶ Never modify the seat belts, seat belt tensioners, seat belt anchorages or seat belt retractors.
▶ Make sure that the seat belts are not damaged, are not worn and are clean.
▶ Always have the seat belts checked immediately after an accident at a qualified specialist workshop.

Mercedes-Benz recommends that you only use seat belts that are approved specifically for your vehicle by Mercedes-Benz.

If the front passenger front airbag is enabled, a child on the front passenger seat may be struck by the front passenger airbag during an accident.

NEVER use a rearward-facing child restraint system on a seat with an ENABLED FRONT AIRBAG, DEATH or SERIOUS INJURY to the CHILD can occur.

When fitting a child restraint system to the front passenger seat, observe the vehicle-specific information ( page 80). Also, always observe the notes on rearward-facing or forward-facing child restraint systems on the front passenger seat.

Information on automatic front passenger airbag shutoff

The front passenger airbag can only be deployed in an accident if the PASSENGER AIR BAG OFF indicator lamp is off. If the front passenger seat is occupied, make sure, both before and during the journey, that the status of the front passenger airbag is correct ( page 48).

Mercedes-Benz GLS (2019) - Information on automatic front passenger airbag shutoff - 1

NOTE Important points to remember if 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.
    Stow 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 airbag on the front passenger side at may deploy. The airbag is deployed regardless of whether the front passenger seat is occupied.

Information on the cushionbag in the reclining rear seat

The cushionbag offers additional occupant protection in the event of frontal impacts. When activated, the cushionbag deploys under the seat cushion. This helps prevent the vehicle occupant from slipping off the seat cushion.

If you install a child restraint system on the reclining rear seat, always observe the additional notes ( page 53).

Protection by the airbags

Depending on the accident situation, an airbag may supplement the protection offered by a correctly fastened seat belt.

Mercedes-Benz GLS (2019) - Protection by the airbags - 1

WARNING Risk of injury or death due to incorrect seat position

If you deviate from the correct seat position, the airbag cannot perform its intended protective function and deployment may even cause further injuries.

In order to avoid risks, each vehicle occupant must always make sure of the following:

  • Fasten seat belts correctly. Pregnant women must take particular care to ensure that the lap belt never lies across the abdomen.
  • Adopt the correct seat position and keep as far away as possible from the airbags.
  • Observe the following information.

Always make sure that there are no objects between the airbag and vehicle occupant.

To avoid the risks resulting from the deployment of an airbag, each vehicle occupant must observe the following information in particular:

  • Before starting your journey, adjust your seat correctly; the driver's seat and front passenger seat should be moved as far back as possible.
    When doing so, always observe the information on the correct driver's seat position ( page 117).
  • Only hold the steering wheel by the steering wheel rim. This allows the airbag to be fully deployed.
  • Always lean against the seat backrest when the vehicle is in motion. Do not lean forwards or against the door or side window. You may otherwise be in the deployment area of the airbags.
  • Always keep your feet on the floor. Do not put your feet on the cockpit, for example.

Your feet may otherwise be in the deployment area of the airbag.

  • If children are travelling in the vehicle, observe the additional notes (→ page 53).
    • Always stow and secure objects correctly.

Objects in the vehicle interior may prevent an airbag from functioning correctly. Each vehicle occupant must always make sure of the following in particular:

- There are no people, animals or objects between the vehicle occupants and an air-bag.

- There are no objects between the seat, doo and door pillar (B-pillar).

- There are no hard objects, e.g. coat hanger, hanging on the grab handles or coat hooks.

- There are no accessory parts, such as mobi navigation devices, mobile phones or cup holders, attached to the vehicle within the deployment area of an airbag, e.g. on the cockpit, on the door, on the side window o on the side wall trim.

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

- There are no heavy, sharp-edged or fragile objects in the pockets of your clothing. Store such objects in a suitable place.

Limited protection provided by airbags

WARNING Risk of injury due to modifications to the airbag cover

If you modify the cover of an airbag or affix objects such as stickers to it, the airbag may no longer function correctly.

▶ Never modify the cover of an airbag and do not affix objects to it.

The installation location of an airbag is identified by the AIRBAG symbol ( page 43).

WARNING Risk of injury or death due to the use of unsuitable seat covers

Unsuitable seat covers can obstruct or prevent the deployment of the airbags integrated into the seats.

Consequently, the airbags cannot protect vehicle occupants as they are designed to do. In addition, the operation of the automatic front passenger airbag shutoff could be restricted.

You should only use seat covers that have been approved for the corresponding seats by Mercedes-Benz.

WARNING Risk of injury due to malfunctions of the sensors in the door panelling

Sensors to control the airbags are located in the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the function of the sensors being impaired. The airbags might therefore not function properly any more.

Consequently, the airbags cannot protect vehicle occupants as they are designed to do.

▶ Never modify the doors or parts of the doors.
Always have work on the doors or door panelling carried out at a qualified specialist workshop.

WARNING Risk of injury due to deployed airbag

A deployed airbag no longer offers any protection and cannot provide the intended protective function in the event of an accident.

Have the vehicle towed to a qualified specialist workshop in order to have the deployed airbag replaced.

Have deployed airbags replaced immediately.

Status of the front passenger front airbag

Function of the automatic front passenger airbag shutoff

The automatic front passenger airbag shutoff is able to detect whether the front passenger seat is occupied by a person or a child restraint system. The front passenger airbag is enabled or disabled accordingly.

When fitting a child restraint system to the front passenger seat, always make sure of the following:

  • Ensure that the child restraint system is positioned correctly ( page 59).
    • Always observe the child restraint system manufacturer's installation instructions.
  • Never place objects, e.g. cushions, under or behind the child restraint system.
  • Fully retract the seat cushion length adjustment.
  • The entire base of the child restraint system must always rest on the sitting surface of the front passenger seat.

  • The backrest of the forward-facing child restraint system must, as far as possible, be resting on the seat backrest of the front passenger seat.

  • The child restraint system must not touch the roof or be put under strain by the head restraints. Adjust the seat backrest inclination and the head restraint setting accordingly.

WARNING Risk of injury or death due to objects between the seat surface and the child restraint system

Objects between the seat surface and the child restraint system could affect the function of the automatic front passenger front airbag shutoff.

This could result in the front passenger front airbag not functioning as intended during an accident.

Do not place any objects between the sitting surface and the child restraint system.

The entire base of the child restraint system must always rest on the sitting surface of the front passenger seat.
The backrest of the forward-facing child restraint system must, as far as possible, be resting on the seat backrest of the front passenger seat.
Always comply with the child restraint system manufacturer's installation instructions.

A person on the front passenger seat must observe the following information:

  • Fasten seat belts correctly (→ page 39).
  • Sit in an almost upright seat position with their back against the seat backrest.
  • Sit with their feet resting on the floor, if possible.

The front passenger airbag may otherwise be disabled by mistake, for example in the following situations:

- 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 sitting surface.

WARNING Risk of injury or death due to deactivated front passenger airbag

If the PASSENGER AIRBAG OFF indicator lamp is lit, the front passenger airbag is disabled. It will not be deployed in the event of an accident and cannot perform its intended protective function.

A person in the front passenger seat could then, for example, come into contact with the vehicle interior, especially if the person is sitting too close to the cockpit.

If the front passenger seat is occupied, always ensure that:

- The classification of the person in the front passenger seat is correct and the front passenger airbag is enabled or disabled in accordance with the person in the front passenger seat.

- The front passenger seat has been moved as far back as possible.

• The person is seated correctly.

Ensure, both before and during the journey, that the status of the front passenger airbag is correct.

If the front passenger seat is occupied, the classification of the person or child restraint system on the front passenger seat takes place after the front passenger airbag shutoff self-test. The PASSENGER AIR BAG indicator lamps display the status of the front passenger airbag.

Always observe the notes on the function of the PASSENGER AIR BAG indicator lamps ( page 48).

Function of the PASSENGER AIR BAG indicator lamps
Mercedes-Benz GLS (2019) - WARNING Risk of injury or death due to deactivated front passenger airbag - 1

text_image PASSENGER ON • AIR BAG OFF

Vehicles without automatic front passenger airbag shutoff have a special sticker affixed to the side of the cockpit on the front passenger side ( page 79).

Self-test of automatic front passenger airbag shutoff

When the ignition is switched on, a self-test is performed during which the two PASSENGER AIR BAG ON and OFF indicator lamps light up simultaneously.

The status of the front passenger airbag is displayed after the self-test:

  • PASSENGER AIR BAG ON lights up for 60 seconds, subsequently both indicator lamps are off (PASSENGER AIR BAG ON an OFF): the front passenger airbag is able to deploy in the event of an accident.
  • PASSENGER AIR BAG OFF lights up continuously: the front passenger airbag is disable. It will then not be deployed in the event of an accident.

If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front passenger airbag. The PASSENGER AIR BAG OFF indicator lamp may be lit continuously or be off.

If the PASSENGER AIR BAG OFF indicator lamp and the restraint system warning lamp

light up simultaneously, the front passenger seat may not be used. Also in this case, do not fit a child restraint system to the front passenger seat. Have automatic front passenger airbag shutoff checked and repaired immediately at a qualified specialist workshop.

Status display

If the front passenger seat is occupied, ensure, both before and during the journey, that the status of the front passenger airbag is correct for the current situation.

After fitting a rearward-facing child restraint system to the front passenger seat:

-PASSENGER AIR BAG OFF must be lit continuously.

⚠ WARNING Risk of injury or death from using a rearward-facing child restraint system when the front passenger front airbag is enabled

If you secure a child in a rearward-facing child restraint system on the front passenger seat and the PASSENGER AIR BAG OFF indi-

cator lamp is off, the front passenger airbag can deploy in the event of an accident. The child could be struck by the airbag.

Always ensure that the front passenger air-bag is disabled. The PASSENGER AIR BAG OFF indicator lamp must be lit.

NEVER use a rearward-facing child restraint system on a seat protected by an ENABLED FRONT AIRBAG in front of it, DEATH or SERIOUS INJURY to the CHILD can occur.

When fitting a child restraint system to the front passenger seat, observe the vehicle-specific information ( page 80).

Depending on the child restraint system and the stature of the child, the PASSENGER AIR BAG OFF indicator lamp may be off. In this case, do not fit the rearward-facing child restraint system to the front passenger seat.

Instead, fit the rearward-facing child restraint system to a suitable rear seat.

After fitting a forward-facing child restraint system to the front passenger seat: depending on the child restraint system and the stature

of the child, PASSENGER AIR BAG OFF may be lit continuously or be off. Always observe the following information.

A WARNING Risk of injury or death due to incorrect positioning of the forward-facing child restraint system

If you secure a child in a forward-facing child restraint system on the front passenger seat and you position the front passenger seat too close to the cockpit, in the event of an accident, the child could:

  • Come into contact with the vehicle interior if the PASSENGER AIR BAG OFF indicator lamp is lit, for example.
  • Be struck by the airbag if the PASSENGER AIR BAG OFF indicator lamp is off.
    Always move the front passenger seat as far back as possible and fully retract the seat cushion length adjustment. Always make sure that the shoulder belt strap is correctly routed from the seat belt outlet on the vehicle to the shoulder belt guide on the child restraint sys-

tem. The shoulder belt strap must be routed forwards and downwards from the seat belt outlet. If necessary, adjust the seat belt outlet and the front passenger seat accordingly.

Always observe the child restraint system manufacturer's installation instructions.

When fitting a child restraint system to the front passenger seat, observe the vehicle-specific information ( page 80).

If a person is sitting on the front passenger seat: PASSENGER AIR BAG OFF may be lit continuously or be off, depending on the person's stature.

A person on the front passenger seat must always observe the following information:

- If the front passenger seat is occupied by an adult or a person with a stature corresponding to that of an adult, the PASSENGER AIR BAG OFF indicator lamp must be off. This indicates that the front passenger airbag is enabled.

If the PASSENGER AIR BAG OFF indicator lamp is lit continuously, an adult or person with a build corresponding to that of an adult should not use the front passenger seat. Instead, they should use a rear seat.

- If the front passenger seat is occupied by a person of smaller stature (e.g. a teenager or small adult), the PASSENGER AIR BAG OFF indicator lamp either lights up continuously or remains off, depending on the result of the classification.

  • If the PASSENGER AIR BAG OFF indicator lamp is off: move the front passenger seat as far back as possible, or the person of smaller stature should use a rear seat.
  • If the PASSENGER AIR BAG OFF indicator lamp is lit continuously: the person of smaller stature should not use the front passenger seat.

WARNING Risk of injury or death when the PASSENGER AIR BAG OFF indicator lamp is lit

If the PASSENGER AIR BAG OFF indicator lamp remains lit after the system self-test, the front passenger airbag is disabled. It will not be deployed in the event of an accident. In this case, the front passenger airbag cannot perform its intended protective function, e.g. when a person is seated in the front passenger seat.

That person could, for example, come into contact with the vehicle interior, especially if the person is sitting too close to the cockpit.

If the front passenger seat is occupied, always ensure that:

- The classification of the person in the front passenger seat is correct and the front passenger airbag is enabled or disabled in accordance with the person in the front passenger seat.

  • The person is seated properly with a correctly fastened seat belt.
  • The front passenger seat has been moved as far back as possible.

Be sure to also observe the following further related subjects:

  • Child restraint system on the front passenger seat ( page 80).
  • Suitable positioning of the child restraint system ( page 59).

PRE-SAFE® system

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: close the sliding sunroof.
  • Vehicles with memory function: move the front passenger seat to a more favourable seat position.
  • Vehicles with memory function in the rear compartment: move the outer rear seats to a more favourable seat position.
  • Vehicles with multicontour seat: increase the air pressure in the seat side bolsters of the seat backrest.
  • PRE-SAFE® Sound: provided that the multi-media system is switched on, generates 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 are 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 releases.

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

PRE-SAFE® PLUS can detect certain impacts, particularly an imminent rear impact, and take pre-emptive 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.
  • Activating the rear hazard warning lights at a higher flashing frequency.

- Increasing brake pressure when the vehicle is stationary. This brake application is cancelled 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 reversing or
  • when the vehicle is towing a trailer and there is a risk of a rear impact

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 front seat vehicle occupant's upper body towards the centre 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 impulse side inoperative See Owner's Manual (→ page 652) display message appears.

Safely transporting children in the vehicle

Always observe when children are travelling in the vehicle

Also strictly observe the safety notes for the specific situation. In this way you can recognise potential risks and avoid dangers if children are travelling in the vehicle ( page 53).

Be diligent

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

To improve protection for children younger than 12 years old or under 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 fitting a child restraint system ( page 59).

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 fit a child restraint system to a rear seat.

Generic term "child restraint system"

The generic term child restraint system is used in this Owner'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 with a backrest and seat belt guide

Mercedes-Benz recommends using a child booster seat with a backrest.

The child restraint system must be appropriate to the age, weight and size of the child.

Always observe the legal requirements when using a child restraint system in the vehicle. Make sure that the child restraint system is approved in accordance with the valid test specifications and guidelines. Further information can be obtained at a qualified specialist workshop. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.

Only use approved child restraint systems

Only child restraint systems that meet the following UNECE standards are permitted for use in the vehicle:

- UN-R44

• UN-R129 (i-Size child restraint systems)

Information on child restraint system approval categories and details on the approval label on the child restraint system ( page 60).

Detecting risks, avoiding danger

Securing systems for child restraint systems in the vehicle

Only use the following securing systems for child restraint systems:

• the ISOFIX or i-Size mounting brackets
• the vehicle's seat belt system
• the Top Tether anchorages

Fitting an ISOFIX or an i-Size child restraint system is preferred.

Simply attaching to the securing rings on the vehicle can reduce the risk of fitting the child restraint system incorrectly.

When securing a child with the integrated seat belt of the ISOFIX or i-Size child restraint system, always comply with the permissible gross weight for the child and child restraint system ( page 69).

Advantage of a rearward-facing child restraint system

It is preferable to transport a baby or a small child in a suitable rearward-facing child restraint system. In this case, the child sits in the opposite direction to the direction of travel and faces backwards.

Babies and small children have comparatively weak neck muscles in relation to the size and weight of their head. The risk of injury to the cervical spine during an accident can be reduced a rearward-facing child restraint system.

Always secure a child restraint system correctly

A WARNING Risk of injury or death caused by incorrect installation of the child restraint system

If the child restraint system is incorrectly installed on a suitable seating position, it cannot perform its intended protective function.

In particular, the child cannot be restrained in the event of an accident, heavy braking or a sudden change of direction.

Always comply with the manufacturer's installation instructions for the child restraint system and its correct use.
▶ Make sure that the entire base of the child restraint system always rests on the sitting surface of the seat.
▶ Never place objects, e.g. cushions, under or behind the child restraint system.

Always use child restraint systems with the original cover designed for them.
Always replace damaged covers with genuine covers.

A WARNING Risk of injury or death due to unsecured child restraint systems in the vehicle

If the child restraint system is not correctly installed or secured, it could release, in particular, in the event of an accident, sudden braking or a sudden change in direction.

The child restraint system could be flung around and hit vehicle occupants.

Always install child restraint systems correctly, even when not in use.
Always comply with the child restraint system manufacturer's installation instructions.

• Always observe the child restraint system manufacturer's installation and operating

instructions as well as the vehicle-specific information:

  • Fit the ISOFIX or i-Size child restraint system to the rear seat ( page 69).
  • Secure the child restraint system with the seat belt on the rear seat ( page 78).
  • Secure the child restraint system with the seat belt on the front passenger seat ( page 80). Observe the specific instructions for the rearward-facing and forward-facing child restraint systems ( page 80).

If the front passenger seat is occupied, ensure, both before and during the journey, that the status of the front passenger airbag is correct for the current situation ( page 48).

  • Observe the warning labels in the vehicle interior and on the child restraint system.
  • Also secure Top Tether if present.

Notes for Mercedes-Maybach vehicles with a reclining rear seat

When fitting a child restraint system, move the reclining rear seat backrest to an almost upright position. The reclining rear seat backrest must be in contact with the child restraint system. Observe the notes on the cushionbag ( page 43).

If you fit a child restraint system to the reclining rear seat, be sure to observe the child restraint system manufacturer's installation instructions.

Do not alter the child restraint system

⚠ WARNING Risk of injury due to alterations to the child restraint system

The child restraint system may no longer function as it is supposed to if you make alterations or attach objects to it, e.g. toys or unsuitable accessories. This poses an increased risk of injury!

Never alter the child restraint system. Only attach accessories which the manufacturer of the child restraint system has authorised especially for this child restraint system.

Mercedes-Benz recommends Mercedes-Benz care products for cleaning child restraint systems recommended by Mercedes-Benz.

Only use child restraint systems which are in proper working condition

⚠ 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 a load in an accident may then not be able to perform their intended protective function.

In particular, the child cannot be restrained in the event of an accident heavy braking or a sudden change of direction.

Always replace child restraint systems immediately 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

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

Always make sure that the child restraint system is not exposed to direct sunlight.
▶ Protect it 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.

Observe when stopping or parking

WARNING Risk of accident and injury due to children left unattended in the vehicle

If children are left unattended in the vehicle, they could:

  • Open doors, thereby endangering other persons or road users.
  • Get out and be struck by oncoming traffic.
  • Operate vehicle equipment and become trapped, for example.

In addition, the children could also set the vehicle in motion, for example by:

  • Releasing the parking brake.
  • Changing the transmission position.
    • Starting the vehicle.

▶ Never leave children unattended in the vehicle.

When leaving the vehicle, always take the key with you and lock the vehicle.

WARNING -Risk of injury or death if the permissible gross mass of the child and child restraint system is exceeded

For ISOFIX or i-Size child restraint systems in which the child is secured using the seat integrated in the child restraint system, the permissible gross mass of the child and child restraint system is 33 kg.

If the child and the child restraint system together weigh more than 33 kg, the ISOFIX or i-Size child restraint system with integrated seat belt does not offer sufficient protection. Too much load may be placed on the ISOFIX or i-Size child restraint systems and the child may not be restrained correctly in the event of an accident, for example.

If the child and the child restraint system together weigh more than 33 kg,

use only an ISOFIX or i-Size child restraint system with which the child is secured with the vehicle seat belt.

Also secure the child restraint system with the Top Tether belt, if available.

Always comply with the information about the mass of the child restraint system:

  • in the manufacturer's installation and operating instructions for the child restraint system used
  • on a label on the child restraint system, if present

Regularly check that the permissible gross mass of the child and child restraint system is still complied with.

When fitting a child restraint system, observe the following:

√ Always observe the correct use of the seats and consider their suitability for attaching a child restraint system.

ISOFIX child seat securing system ( page 63)

or

i-Size child seat securing system (→ page 67)

√ Always comply with the manufacturer's installation and operating instructions for the child restraint system used.
√ Make sure that the child's feet do not come into contact with the front seat. If necessary, move the front seat forward slightly.
When fitting an ISOFIX child restraint system, also observe the following:
√ When using a Group 0/0+ baby car seat and a Group 1 rearward-facing child restraint system on a rear seat: adjust the front seat so that the seat does not touch the child restraint system.
When using a Group 1 forward-facing child restraint system: remove the head restraint from the respective seat, if possible. In addition, the backrest of the child restraint system must, as far as possible, lie flat against the backrest of the vehicle seat.

Once the child restraint system has been removed, replace the head restraints immediately and adjust them correctly.

√ When using a child restraint system on a seat on the third row of seats: adjust the front seat so that it does not touch the child restraint system, and move the seat backrest of the front seat into an upright position if necessary.
For certain child restraint systems in weight group 2 or 3, there may be restrictions on the maximum size setting, e.g. due to possible contact with the roof.
√ The child restraint system must not be tensioned between the roof and the seat cushion and/or be fitted facing the wrong direction. Where possible, adjust the seat cushion inclination accordingly.
√ The child restraint system must not be put under strain by the head restraints. Adjust the head restraints accordingly.

When fitting an i-Size child restraint system, also observe the following:
√ When using a rearward-facing child restraint system: adjust the front seat so that it does not touch the child restraint system.
When using a forward-facing child restraint system: remove the head restraint from the respective seat, if possible. In addition, the backrest of the child restraint system must, as far as possible, lie flat against the backrest of the vehicle seat. Once the child restraint system has been removed, replace the head restraints immediately and adjust them correctly.

Before every journey, make sure that the ISOFIX child restraint system or the i-Size child restraint system is engaged correctly in both mounting brackets in the vehicle.

NOTE Be careful not to damage the seat belt for the centre seat when fitting the child restraint system
Make sure that the seat belt is not trapped.

Always switch off the engine before opening the tailgate.
▶ Never drive with the tailgate open.

⚠ WARNING Risk of injury from unsecured items in the vehicle

If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip over or be thrown around and thereby hit vehicle occupants.

There is a risk of injury, particularly in the event of sudden braking or a sudden change in direction.

Always stow objects in such a way that they cannot be thrown around.
Before the journey, secure objects, luggage or loads against slipping or tipping over.

WARNING Risk of injury from inadequate stowage of objects

If you do not adequately stow objects in the vehicle interior, they could slip or be tossed around and thereby strike vehicle occupants. In addition, cup holders, open stowage spaces and mobile phone brackets cannot always restrain the objects they contain in the event of an accident.

There is a risk of injury, particularly in the event of sudden braking or a sudden change in direction.

Always stow objects in such a way that they cannot be tossed around in these or similar situations.

Always make sure that objects do not project from stowage spaces, luggage nets or stowage nets.
▶ Close all sealable stowage spaces before you start your journey.
Stow and secure objects that are heavy, hard, pointed, sharp-edged, fragile or too large in the load compartment.

WARNING Risk of burns from the tailpipe and tailpipe trims

The exhaust tailpipe and tailpipe trims can become very hot. If you come into contact with these parts of the vehicle, you could burn yourself.

▶ Always be particularly careful around the tailpipe and the tailpipe trims and supervise children especially closely in this area.

▶ Allow vehicle parts to cool down before touching them.

The driving characteristics of your vehicle are dependent on the distribution of the load within the vehicle. You should bear the following in mind when loading the vehicle:

  • never exceed the permissible gross mass or the permissible axle loads for the vehicle (including occupants).

Running-in notes

To preserve the engine during the first 1,500 km:

  • drive at varying road speeds and engine speeds.
  • drive the vehicle in drive program C or E.
  • shift to the next highest gear at the very latest when the needle reaches the last third before the red area in the rev counter.
  • do not shift down a gear manually in order to brake.
  • avoid overstraining the vehicle, e.g. driving at full throttle.
  • do not depress the accelerator pedal past the pressure point (kickdown).
  • only increase the engine speed gradually and accelerate the vehicle to full speed after 1,500 km.

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

Please also observe the following running-in notes:

  • in certain driving and driving safety systems, the sensors adjust automatically while a tain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in process.
  • brakepads, brake discs and tyres that are either new or have been replaced only achieve optimum braking effect and grip after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal.

Notes on optimised acceleration

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

Do not use the optimised acceleration on public roads. Individual wheels could spin and you

should 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 253).

Pulling away with optimised acceleration

WARNING Risk of skidding and having an accident from wheels spinning

When you use optimised acceleration, individual wheels could spin and you could lose control of the vehicle.

If ESP ^® is deactivated, there is a risk of skidding and accident!

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

Requirements:

• the vehicle has been run in (→ page 214).
• the vehicle and tyres are in good condition.

- the engine and transmission are at normal operating temperature.

NOTE Increased wear due to optimised acceleration

When pulling away with optimised 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 optimised acceleration.

Engage the D drive position ( page 230).
Move the steering wheel to the straight-ahead position.
Select the sportiest available drive program S ^+ or S (→ page 227).
Deactivating ESP® (→ page 258).
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 pulls away at maximum acceleration.
Switch on ESP once the acceleration procedure is complete.

Ending optimised acceleration

Remove your foot from the accelerator pedal.
Reactivate the ESP.
i After you pull away with optimised acceleration, components of the drivetrain can become very hot, which means that optimised acceleration values may be reached again only 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 jeopardises 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 fit 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 unsuitable footwear

Operating the pedals may be impaired by wearing unsuitable footwear, e.g.:

  • platform shoes
  • high-heeled shoes
  • slippers
    Always wear suitable footwear when driving so that you can operate the pedals safely.

WARNING Risk of accident when switching off the ignition when driving

If you switch off the ignition 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 then need to use considerably more force to steer and brake.

Do not switch off the ignition 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 when the vehicle becomes stuck in snow, for example.

Keep the tailpipe and the area around the vehicle free from snow when the engine or the stationary heater are 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 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 may 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 Causing wear to the brake linings by permanently depressing the brake pedal

Do not permanently depress the brake pedal while driving.

To use 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 misfiring.

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.

Notes on driving on salt-treated roads

The braking effect is limited on salt-treated roads.

Therefore, observe the following notes:

- due to salt build-up on the brake disks and brakepads, the braking distance can increase considerably or result in braking only on one side

- maintain a much greater safe distance to the vehicle in front

To remove salt build-up:

- brake occasionally while 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 aquaplaning

Aquaplaning can take place once a certain amount of water has accumulated on the road surface.

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

- reduce speed

- avoid tyre ruts

- avoid sudden steering movements

- brake carefully

① Also observe the notes on regularly checking wheels and tyres (→ page 605).

Notes on driving through water on the road surface

Water which has entered into the vehicle 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 must drive through water:

- observe the maximum permissible fording depth ( page 646)

- drive at walking pace at most, otherwise water can enter the vehicle interior or engine compartment

- vehicles travelling in front, or oncoming vehicles, can create waves which may exceed maximum permissible height of the water

The braking effect of the brakes is reduced after fording. Brake carefully while paying attention to the traffic conditions until braking power has been fully restored.

Notes on off-road driving

Examples of an event ahead

ECO Assist function

Vehicles with a 48 V on-board electrical system (EQ Boost technology):

ECO Assist analyses 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 (e.g. a speed limit or a roundabout),

Mercedes-Benz GLS (2019) - Vehicles with a 48 V on-board electrical system (EQ Boost technology): - 1

text_image km/h 1 2 3 D 3

① Event ahead
② Distance to the event ahead
3 "Foot off the accelerator" prompt

The number of segments shown ② changes depending on the distance to the event ahead:

  • A few segments: the event ahead is near.
  • Many segments: the event ahead is further away.

When the vehicle nears the event, ECO Assist will calculate the optimal speed for maximum fuel economy and recuperative energy based on the distance, speed and downhill gradient. The Foot off the accelerator ③ message appears in

the multifunction display. The first segments in front of the vehicle will turn green. The remaining segments will initially stay white. If the driver lifts off the accelerator pedal in good time, remaining segments on the display will successively turn green until the event shown is reached. The drivetrain will be set for maximum fuel economy. Recuperation will charge the battery. Recuperation will be adapted to the selected drive program.

The event will be shown for a short time after it has been passed. If there is no response to the Foot off the accelerator prompt, the segments will remain white.

If the event involves a vehicle in front, all segments will immediately turn green once there a response to the Foot off the accelerator prompt.

For active ECO Assist in drive program E, symbol ③ will appear on the multifunction display and on the head-up display beside transmission position D. Symbol ③ will also appear when the assistant display is not selected.

If the system does not intervene during the event ahead, nothing will be displayed. The system is passive.

the ECO Assist is active only in drive programs E and C.

System limits

ECO Assist can function even more precisely if the route is adhered to when route guidance is active. 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 driver must be ready to brake at all times irrespective of whether the system intervenes.

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

- if visibility is poor (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 there is dirt on the windscreen in the vicinity of the multifunction camera or the came is misted up, damaged or obscured.
  • if traffic signs are hard to discern (e.g. due to dirt, snow or insufficient lighting, or because they are obscured).
  • If the information on the navigation system's digital map is incorrect or out of date.
  • If the signs are ambiguous, e.g. traffic signs in roadworks or in adjacent lanes.

Driving and driving safety systems

Driving systems and your responsibility

Your vehicle is equipped with driving systems which assist you in driving, parking and manoeuvring the vehicle. The driving systems are aids and do not relieve you of your responsibility pertaining to road traffic law. 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.

Information on radar and ultrasonic sensors

Some driving and driving safety systems use radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle (depending on the vehicle's equipment).

Depending on the vehicle's equipment, the radar sensors are integrated behind the bumpers and/or behind the radiator grille. The ultrasonic sensors are located in the front and rear bumpers. Keep these parts free of dirt, ice and slus ( page 579). The sensors must not be covered, for example by bicycle racks, overhanging

loads, stickers, foil or foils to protect against stone chipping. Additional licence plate brackets can likewise impair the function of the ultrasonic sensors. In the event of damage to the bumpers or radiator grille, or following a collision impacting the bumpers or radiator grille, have the function of the sensors checked at a qualified specialist workshop. If the sensors are damaged, some driving systems and driving safety systems may no longer function properly.

Function of ABS

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

  • During braking, e.g. at full brake application or insufficient tyre 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. 8 km/h.
  • ABS may be impaired or may not function if malfunction has occurred and the yellow ☑ ABS warning lamp lights up continuously in the instrument cluster after the engine is started.

Functions of Off-road ABS

i Off-road ABS is activated automatically when you select the 📄 or 🌐 drive program.

Off-road ABS is specially adapted for driving off-road:

  • The front wheels lock cyclically during braking.
  • The braking distance is shortened due to the digging-in effect.

System limits

  • Off-road ABS functions at speeds below 40 km/h.
  • If Off-road ABS intervenes, the ability to steer may be restricted.

Function of BAS (Brake Assist System)

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.

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.

Functions of ESP ^® (Electronic Stability Program)

⚠ WARNING Risk of skidding if ESRs malfunctioning

If ESP ^ is malfunctioning, ESP ^ cannot carry out vehicle stabilisation. In addition, other driving safety systems are switched off.

▶ Drive on carefully.
Have ESP ^ checked at a qualified specialist workshop.

Mercedes-Benz GLS (2019) - Functions of ESP ^® (Electronic Stability Program) - 1

WARNING Risk of skidding if ESRs deactivated

If you deactivate ESP, ESP cannot carry out vehicle stabilisation.

ESP® should only be deactivated in the following situations.

ESP ^® can monitor and improve driving stability and traction in the following situations, within physical limits:

  • When pulling away on wet or slippery carriageways.
  • When braking.
  • Vehicles with trailer hitch: in trailer operation from speeds of 65 km/h, if the vehicle/trailer combination begins to sway from side to side.
  • In strong side winds when you are driving faster than 75 km/h.

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

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

ESP ^ is deactivated if the ☐ OFF ESPOFF warning lamp lights up continuously in the instrument cluster:

  • Driving stability will no longer be improved.
  • Vehicles with trailer hitch: stabilisation of the vehicle/trailer combination is no longer active.
    • Crosswind Assist is no longer active.
    • The drive wheels could spin.
    • ETS/4ETS traction control is still active.

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

If the ESP warning lamp flashes in the instrument cluster, one or several vehicle 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 nt is necessary when pulling away.

It can be advantageous to deactivate ESP the following situations to improve traction:

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

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

If the ESP warning lamp lights up continuously, ESP ^ is not available due to a malfunction. Observe the following information:

• Warning and indicator lamps (→ page 711)
• Display messages (→ page 651)

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 carriageway.

If you select the 📄 or 🌐 drive program, a special ETS system specifically suited to off-road terrain is automatically activated.

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 ESPo adapt to different weather and road conditions as well as the driver's preferred driving style. You can select the drive programs using the DYNAMIC SELECT switch ( page 227).

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. 75 km/h and 200 km/h when driving straight ahead or cornering slightly.
  • The vehicle is stabilised by means of a targeted and individual brake application on one side.

Function of ESP® trailer stabilisation

Mercedes-Benz GLS (2019) - Function of ESP® trailer stabilisation - 1

WARNING Risk of accident in poor road and weather conditions

In poor road and weather conditions, the trailer stabilisation cannot prevent lurching of

the vehicle/trailer combination. Trailers with a high centre of gravity may tip over before ESP® detects this.

Always adapt your driving style to suit the current road and weather conditions.

When driving with a trailer, ESPan stabilise your vehicle if the trailer begins to swerve from side to side:

  • ESP® trailer stabilisation is active above speeds of 65 km/h.
  • Slight swerving is reduced by means of a targeted, individual brake application on one side.
  • In the event of severe swerving, the engine output is also reduced and all wheels are braked.

ESP ^® trailer stabilisation may be impaired or may not function if:

- The trailer is not connected correctly or is not detected properly by the vehicle.

Function of EBD (Electronic Brake force Distribution)

EBD is characterised 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 helps you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilisation.

This steering recommendation is given particularly 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:

Function of Active Brake Assist

Active Brake Assist consists of the following functions:

• Distance warning function
• Autonomous braking function
• Situation-dependent braking assistance
• Vehicles with Driving Assistance Package: Evasive Steering Assist and cornering function

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

If Active Brake Assist has detected a risk of collision, a warning tone sounds and the dis-

tance warning lamp lights up in the instrument cluster.

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

If you do not react to the warning, autonomous braking can be initiated in critical situations. In especially critical situations, Active Brake Assist can initiate autonomous braking directly. In this case, the warning lamp and warning tone occur simultaneously with the braking application.

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

natural_image Top-down view of a car under lane markings with a traffic light symbol (no readable text or labels)

If autonomous braking or situation-dependent braking assistance has occurred, display ① appears in the multifunction display and then automatically goes out after a short time. If the autonomous braking function or the situation-dependent braking assistance is triggered, additional preventive measures for occupant protection (PRE-SAFE®) may also be initiated.

Mercedes-Benz GLS (2019) - Function of Active Brake Assist - 2

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
    Always pay careful attention to the traffic situation; do not rely on Active Brake Assist alone. Active Brake Assist is only an aid. The driver is responsible for maintaining a suitable distance to the vehicle in front, vehicle speed and for braking in good time.
    Be prepared to brake or swerve if necessary.

i If the system is unavailable, the OFF display appears in the multifunction display.

Also observe the system limits of Active Brake Assist.

The individual subfunctions are available in the following speed ranges:

The distance warning function issues a warning in the following situations:

- From approximately 30 km/h, if over several seconds the distance maintained to the vehicle travelling in front is too small for the

driven speed, the △ distance warning lamp lights up in the instrument cluster.

- From approximately 7 km/h, if your vehicle is critically close to a vehicle or pedestrian, you will hear an intermittent warning tone and the △ distance warning lamp lights up in the instrument cluster.

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

Brake immediately or take evasive action, provided it is safe to do so and the traffic situation allows this.

The distance warning function can aid you in the following situations with an intermittent warning tone and a warning lamp:

Cancelling a brake application of Active Brake Assist

You can cancel a brake application of 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 manoeuvre to avoid the obstacle.
• There is no longer a risk of collision.
- An obstacle is no longer detected in front of your vehicle.

Evasive Steering Assist (only vehicles with Driving Assistance Package)

Evasive Steering Assist has the following characteristics:

  • The ability to detect stationary or moving pedestrians.
  • Assistance through power-assisted steering if it detects a swerving manoeuvre.

  • Activation by an abrupt steering movement during a swerving manoeuvre.

  • Assistance during swerving and straightening of the vehicle.
  • Reaction from a speed of approximately 20 km/h up to a speed of approximately 70 km/h.

You can prevent the assistance at any time by actively steering.

Cornering function (only vehicles with Driving Assistance Package)

If a danger of collision from an oncoming vehicle is detected when turning across an oncoming lane, autonomous braking can be initiated at speeds below 15 km/h before you have left the lane in which you are driving.

Mercedes-Benz GLS (2019) - Cornering function (only vehicles with Driving Assistance Package) - 1

WARNING Risk of an accident despite Evasive Steering Assist

Evasive Steering Assist cannot always clearly identify objects and complex traffic situations.

In addition, the steering support of Evasive Steering Assist is generally not sufficient to avoid a collision.
In such cases Evasive Steering Assist can:

- give an unnecessary warning or provide assistance

- not give a warning or not provide assistance

Always pay careful attention to the traffic situation; do not rely on Evasive Steering Assist alone.
Be ready to brake and take evasive action, if necessary.
▶ Prevent the assistance by actively steering in non-critical driving situations.
▶ Drive at an appropriate speed if pedestrians are close to the path of your vehicle.

System limits

Full system performance is not available for a few seconds after switching on the ignition or after driving off.

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

  • In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying light conditions.
  • If the sensors are dirty, misted up, damaged or covered.
  • If the sensors are impaired due to interference from other radar sources, e.g. strong radar reflections in multi-storey car parks.
  • If a loss of tyre pressure or a defective tyre has been detected and displayed.
  • If DSR is activated.
  • In complex traffic situations where objects cannot always be clearly identified.
  • If pedestrians or vehicles move quickly into the sensor detection range.
    • If pedestrians are hidden by other objects.

  • If the typical outline of a pedestrian cannot be distinguished from the background.

  • If a pedestrian is not detected as such, e.g. due to special clothing or other objects.
  • On bends with a tight radius.
    The Active Brake Assist sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Brake Assist is unavailable or only partially available during this teach-in period.

Setting Active Brake Assist

Requirements:

• The ignition is switched on.

Multimedia system:

Mercedes-Benz GLS (2019) - Requirements: - 1

The following settings are available:

  • Early
    Medium
  • Late

Select a setting. The setting is retained when the engine is next started.

Deactivating Active Brake Assist

i It is recommended that you always leave Active Brake Assist activated.
Select Off.
The distance warning function, the autonomous braking function and the Evasive Assist are deactivated. When the vehicle is next started, the middle setting is automatically selected.
If Active Brake Assist is deactivated, the symbol appears in the status bar of the multifunction display.

Function of Adaptive Brake Lights

Adaptive Brake Lights warn following traffic in an emergency braking situation with the following actions:

  • By flashing the brake lamps
  • By activating the hazard warning lights

If the vehicle is braked sharply from speeds above 50 km/h, the brake lamps flash rapidly. This provides traffic travelling behind you with an even more noticeable warning.

If the vehicle is travelling at speeds of more than 70km / h at the beginning of the brake application, the hazard warning lights switch on once the vehicle is stationary. When you pull away again, the hazard warning lights will switch off automatically at approximately 10km / h . You can also switch off the hazard warning lights using the hazard warning button.

Cruise control and limiter

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.

Cruise control is operated using the corresponding steering wheel buttons. You can store any

speed above 20 km/h up to the maximum speed or up to the set winter tyre limit. The maximum speed is reduced when driving in LOW RANGE off-road gear ( page 233).

If you fail to adapt your driving style, cruise control can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. Cruise control is only an aid. The driver is responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.

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

Displays in the multifunction display

The status of cruise control and the stored speed are shown in the multifunction display.

① Cruise control is selected
② Speed is saved, cruise control is deactivated
3 Speed is saved, cruise control is activated
The segments extending from the current stored speed to the end of the scale, or to the set winter tyre limit, light up 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 engine's braking effect. 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.
    • If you are driving when visibility is poor.

Function of the limiter

The limiter restricts the speed of the vehicle. To reduce the speed to the set speed, the limiter applies the brakes automatically.

You can limit the speed as follows:

  • Variable: for speed restrictions, e.g. in built-up areas.
    • Permanent: for long-term speed restrictions, e.g. when driving in winter tyre mode.

The variable limiter is operated using the corresponding steering wheel buttons. You can store any speed above 20 km/h up to the maximum speed or up to the set winter tyre limit. You can also perform settings while the vehicle is stationary if the vehicle has been started.

If you fail to adapt your driving style, the limiter can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. The limiter is only an aid. The driver is responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.

Mercedes-AMG vehicles: the limiter is available up to a maximum speed of 250 km/h.

Kickdown

If you depress the accelerator pedal beyond the pressure point (kickdown), the variable limiter switches to passive mode. The Limiter passive message appears in the multifunction display.

After completion of kickdown, the variable limiter is activated again in the following situations:

  • If the driven speed drops below the stored speed.
  • If the stored speed is called up.
    • If you store a new speed.

Operating cruise control or the variable limiter

⚠ WARNING Risk of accident due to stored speed

Permanent limiter

If the vehicle should never exceed a specific speed (e.g. for driving in winter tyre mode), you can set this speed with the permanent limiter.

You do this by limiting the speed to a value between 160 km/h and 240 km/h in the multi-media system ( page 269).

Shortly before the set speed is reached, it appears in the multifunction display. When you confirm the message with ←, display messages no longer appear until you switch off the vehicle. The speed will only be displayed again once the vehicle has been restarted or if the set speed is changed.

The permanent limiter does not switch to passive mode even during kickdown and the driven speed remains below the set speed.

DSR (Downhill Speed Regulation)

Function of DSR (Downhill Speed Regulation)

DSR is an aid to assist you when driving downhill. It keeps the speed of travel at the selected target speed. The steeper the downhill gradient, the greater the DSR braking effect on the vehicle. On flat stretches of road and uphill gradients, the DSR brakes the vehicle minimally or not at all.

When DSR is activated and the transmission is position [D], [R] or [N], DSR controls the drivin speed. The target speed can be set to a value between 2 km/h and 18 km/h. By braking or accelerating, you can drive at a higher or lower speed than the target speed at any time.

DSR is deactivated automatically if you drive at speeds greater than 45 km/h or select drive

program S or S'. The off message then appears in the multifunction display. The status indicator in the multifunction display disappears. You also hear a warning tone.

Information on DSR

Mercedes-Benz GLS (2019) - Information on DSR - 1

WARNING Risk of skidding and having an accident when DSR is activated on slippery road surfaces

If the speed driven and the target speed differ, and you activate DSR on a slippery road surface, the wheels may lose traction.

Take into account the road surface and the difference between the driving speed and target speed before activating DSR.

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

You are always responsible for keeping control of the vehicle and for assessing whether the downhill gradient can be managed. Depending on road surface and tyres, DSR may not always be able to keep to the target speed. Select a target speed suitable for the environmental conditions and also apply the brakes yourself if required.

Activating/deactivating DSR (vehicles with Off-road package or E-Active Body Control) Requirements:

- You are driving at 40 km/h or slower. If the current vehicle speed is too high, the Max. speed 40 km/h message appears in the multifunction display.

Active Distance Assist DISTRONIC

Function of Active Distance Assist DISTRONIC
Mercedes-Benz GLS (2019) - Active Distance Assist DISTRONIC - 1

natural_image Aerial view of a car driving on a multi-lane road with lane markings (no visible text or symbols)

Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles in front are detected, the set distance is maintained, if necessary, until the vehicle comes to a halt. The vehicle accelerates or brakes depending on the distance to the vehicle in front and

the set speed. The speed and distance to the vehicle in front are set and saved on the steering wheel on vehicles without the Driving Assistance Package, in the range between 20 km/h and 200 km/h and, on vehicles with the Driving Assistance Package, in the range between 20 km/h and 210 km/h. The maximum speed reduced when driving in LOW RANGE off-road gear ( page 233).

Other features of Active Distance Assist DISTRONIC:

  • Adjusts the driving style depending on the selected drive program (fuel efficient, comfortable or dynamic) ( page 225)
  • Vehicles with Driving Assistance Package: reacts to stationary vehicles detected in urban speed ranges (except bicycles and motorcycles)
  • 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: takes one-sided overtaking restrictions into account on motorways or on multi-lane

roads with separate carriageways (country-dependent)

Vehicles with Active Parking Assist and Driving Assistance Package: if the vehicle has been braked to a standstill on multi-lane, separate carriageways by Active Distance Assist DISTRONIC, it can automatically follow the vehicle in front driving off again within 30 seconds a critical situation is detected when driving off, visual and acoustic warning is given indicating that the driver must now take control of the vehicle. The vehicle is not accelerated any further. Active Distance Assist DISTRONIC is only an aid. The driver is responsible for keeping a safe distance to the vehicle in front, for vehicle speed and for braking in good time.

System limits

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

- In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying light conditions.

  • If there is swirling dust, e.g. when driving off-road or on sandy surfaces.
  • The windscreen in the area of the camera is dirty, misted up, damaged or covered.
    • If the radar sensors are dirty or covered.
  • In multi-storey car parks or on roads with steep uphill or downhill gradients.
    • If there are narrow vehicles in front, such as bicycles or motorcycles.

In addition, on slippery roads, braking or accelerating can 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 maximum possible deceleration. If this deceleration is not sufficient, Active Distance Assist DISTRONIC alerts you with a visual and acoustic warning.

In these cases, adjust your speed and keep a sufficient distance.
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.

Always observe the traffic conditions carefully and react accordingly.

Operating Active Distance Assist DISTRONIC Requirements:

• The vehicle has been started.
• The electric parking brake is released.
- ESP ^ is activated and is not intervening.
• The transmission is in position D.
• The driver's door is closed.

Function of Active Speed Limit Assist

The following function is country-dependent and only available in conjunction with the Driving Assistance Package.

Mercedes-Benz GLS (2019) - Function of Active Speed Limit Assist - 1

text_image 60 80 100 40 myh 120 20 140 80

If a change in the speed limit is detected and automatic adoption of speed limits is activated, the new speed is automatically adopted as the stored speed ( page 330).

The driven speed is adjusted when the vehicle is level with the traffic sign at the latest. In the case of signs indicating entry into an urban the speed is adapted according to the speed permitted within the urban area. The speed display in the Instrument Display is always used when the vehicle is level with the traffic sign.

If there is no speed restriction on an unlimited stretch of road (e.g. on a motorway), the recommended speed is automatically adopted as the stored speed. The system uses the speed stored on an unlimited stretch of road as the recommended speed. If you do not alter the stored speed on an unlimited stretch of road, the recommended speed is 130 km/h.

If Active Distance Assist DISTRONIC has been put into passive mode by pressing the accelerator pedal, only speed limits which are higher than the set speed are adopted.

Active Speed Limit 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 maximum permissible speed also depends on factors such as the road surface and traffic conditions.

System limits

Temporary speed restrictions (e.g. for a certain are time or due to weather conditions) cannot be properly detected by the system. The maximum limpermissible speed applying to a vehicle with a updailer is not detected by the system. In these situations you must adjust your speed yourself.

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:

• In the wet 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

The following function is country-dependent and only available in conjunction with the Driving Assistance Package.

When Active Distance Assist DISTRONIC is activated, the vehicle speed will be adjusted accordingly to the route events ahead. Depending on the drive program selected, the vehicle negotiates a route event ahead in a fuel-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 configured in the multimedia system ( page 277).

The following route events are taken into account:

  • Bends
    • T-junctions, roundabouts and toll stations
  • Turns and exits
  • Traffic jams ahead (only with Live Traffic (→ page 458))

When the toll station is reached, Active Distance Assist DISTRONIC adopts the speed as the stored speed.

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

  • Turning off at junctions
  • Driving on slowing-down lanes
  • Driving on lanes adjacent to slowing-down lanes

The driver is responsible for choosing the right speed and observing other road users. This applies in particular to junctions, roundabouts and traffic lights, as route-based speed adaptation does not brake the vehicle to a standstill.

When route guidance is active, the first speed adjustment is carried out automatically. If the turn signal indicator is switched on, the selected route is confirmed and further speed adjustment is activated.

Speed adjustment is cancelled in the following cases:

  • If the turn signal indicator is switched off before the route event.
  • 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, for example unclear roads, lane narrowing, wet road surfaces, snow or ice, or when driving with a trailer, the speed adjustment made by the system may not always be suitable. In these situations the driver must intervene accordingly.

⚠ WARNING Risk of accident in spite of route-based speed adjustment

Route-based speed adjustment might 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 road construction areas
    • In bad weather or road conditions
    • If the accelerator pedal is depressed
  • In the event of electronically displayed speed limitations
    Adjust the speed to the traffic situation.

Setting route-based speed adaptation

Requirements:

- Active Distance Assist DISTRONIC is activated.

Multimedia system:

Active Steering Assist

Function of Active Steering Assist

The following function is country-dependent and only available in conjunction with the Driving Assistance Package.

Active Steering Assist is only available up to a speed of 210 km/h. The system helps you to stay in the centre of the lane by means of moderate steering interventions. Depending on the speed driven, Active Steering Assist uses the vehicles ahead and lane markings as a reference.

Depending on the country, in the lower speed range Active Steering Assist can use the surrounding traffic as a reference. If necessary, Active Steering Assist can then also provide assistance when driving outside the centre of the lane to form a rescue lane, for example.

When the system is actively steering, the symbol is shown in green in the multifunction display.

If the detection of lane markings and vehicles ahead is impaired, Active Steering Assist switches to passive mode. The system provides no support in this case. During the transition from active to passive status, the [+] symbol is shown as enlarged and flashing. Once the system is passive, the [+] symbol is shown as grey in the multifunction display.

Steering and touch detection

The driver is required to keep their 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. The driver must expect a change from active to passive mode or vice versa at any time.

Mercedes-Benz GLS (2019) - Steering and touch detection - 1

natural_image Illustration of hands holding a car steering wheel with a numbered circle pointing to it (no text or symbols on the diagram itself)

If the system detects that the driver has not steered the vehicle for a considerable period of time or has removed their hands from the steering wheel, an optical warning is given first. Display ① appears in the multifunction display. If the driver still does not steer the vehicle, or gives no confirmation to the system, a warning tone sounds in addition to the visual warning message.

The warning is not issued, or is stopped, when the driver gives confirmation to the system:

• The driver steers the vehicle.

- The driver presses a steering wheel button operates Touch Control.

If Active Steering Assist detects that a system limit has been reached, a visual warning is issued and a warning tone sounds.

Active Steering Assist is only an aid. The driver is responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Before changing lanes, the driver must make sure that the neighbouring lane is free (glance over the shoulder).

System limits

Active Steering Assist has a limited steering torque for lateral guidance. In some cases, the steering intervention is not sufficient to keep the vehicle in the lane or to drive through exits.

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 light conditions or strong shadows on the carriageway.
  • There is glare, e.g. from oncoming traffic, direct sunlight or reflections.

or Insufficient road illumination.

  • The windscreen is dirty, misted up, damaged or covered in the vicinity of the camera, e.g. by a sticker.
  • No, or several, unclear lane markings are present for one lane, or the markings change quickly, e.g. in a construction area or junctions.
  • 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 small and the lane markings thus 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.

On The system does not provide assistance in the following conditions:

  • On tight bends and when turning.
  • When crossing junctions.
  • At roundabouts or toll stations.
  • When towing a trailer.

  • When actively changing lane without switching on the turn signal indicator.

  • When the tyre pressure is too low.

Depending on the selected vehicle settings, Active Steering Assist may be unavailable. Observe the status display of Active Steering Assist in the multifunction display

(→ page 283).

    • Active Steering Assist is switched on and active.

Mercedes-Benz GLS (2019) - Function of Active Lane Change Assist - 1

text_image Lane change to the left

If no vehicle is detected in the adjacent lane and a lane change is permitted, the lane change begins after the driver has activated the turn signal indicator. This is shown to the driver with a green arrow ② next to the steering wheel symbol. The Lane change to the left message also appears, for example. If Active Lane Change Assist has been activated with the turn signal indicator but a lane change is not immediately possible, a grey arrow ① appears next to the steering wheel symbol, which remains green. When the lane change assistance starts, the turn signal indicator is automatically activated along with the display in the multifunction display.

If the assistance graphic is shown when changing lanes, the lane change display appears with an additional arrow pointing towards the adjacent lane ( page 283).

If a lane change is not possible, the arrow fades out after a few seconds and a new lane change must be initiated. An immediate lane change is only possible on motorway sections without speed limits.

If the system is impaired, Active Lane Change Assist may be cancelled. If it is cancelled, the Lane change cancelled message appears in the multifunction display and a warning tone sounds.

Mercedes-Benz GLS (2019) - Function of Active Lane Change Assist - 2

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

Lane Change Assist cannot always detect clearly 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 neighbouring lane is free and there is no danger to other road users.

▶ Monitor the lane change.

A 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 torques.

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

System limits

The system limitations of Active Steering Assist apply to Active Lane Change Assist ( page 278).

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

  • The sensors in the rear bumper are dirty, damaged or covered by a sticker or ice and snow, for example.
    • The exterior lighting is malfunctioning.

The Active Lane Change Assist sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Lane Change Assist is unavailable or only partially available during this teach-in process, no arrow appears next to the Active Steering Assist symbol when the turn signal indicator is activated.

E-ACTIVE BODY CONTROL

Function of E-ACTIVE BODY CONTROL

E-ACTIVE BODY CONTROL is an electrohydraulic suspension system with variable damping for improved driving comfort. The all-round level control system ensures the best possible suspension and constant ground clearance, even with a laden vehicle. When driving at speed, the vehicle is lowered automatically to improve driving safety and to reduce fuel consumption. The suspension setting is adjusted depending on t road surface, vehicle load and the drive program selected.

The ROAD SURFACE SCAN function detects areas of unevenness in the road before you drive over them by means of a multifunction camera. This reduces chassis movements.

The damping is adjusted individually to each wheel and depends on the following factors:

- Driving style, e.g. sporty

• Road condition, e.g. bumps
- Drive program

E-ACTIVE BODY CONTROL is comprised of the following functions and components:

• ROAD SURFACE SCAN
• Curve inclination function CURVE
- Recovery mode
• Individual wheel control

Function of ROAD SURFACE SCAN

① This function is not available in all countries.

Mercedes-Benz GLS (2019) - Function of ROAD SURFACE SCAN - 1

natural_image Line drawing of a car front view with a close-up inset showing a black object labeled '1' (no text or symbols on the main diagram)

The ROAD SURFACE SCAN function monitors the road in front of your vehicle using a multifunction camera ①. ROAD SURFACE SCAN detects unevenness in the road surface, e.g. bumps, before the vehicle drives over them. Chassis movements are reduced and driving comfort is increased.

ROAD SURFACE SCAN is automatically activated if the following conditions are met:

  • Drive program [C] (Comfort) or [CV] (CURVE) is selected.
    • The vehicle is set to the normal level.
  • You are driving at a speed between 7 km/h and 180 km/h.

System limits

ROAD SURFACE SCAN can be impaired in the following situations or can stop functioning:

  • If the carriageway is insufficiently lit, e.g. at night.
  • In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying light conditions.
  • If the windscreen in the area of multifunction camera ① is dirty, misted up, damaged or covered.
  • If the road surface has no optic structure or reflects light.
  • If you are driving too close to the vehicle in front.

  • If sections of the route have a very small radius of curvature.

  • During abrupt driving manoeuvres, e.g. heavy braking or sudden acceleration.

Observe the notes on cleaning the multifunction camera ( page 579).

Function of recovery mode

Mercedes-Benz GLS (2019) - Function of recovery mode - 1

WARNING Risk of injury due to the vehicle moving up and down

When free driving mode is activated, the vehicle bounces up and down. Body parts could become trapped if they are between the vehicle body and the tyres or underneath the vehicle.

Make sure that nobody is under or in the immediate vicinity of the vehicle when free driving mode is activated.

Mercedes-Benz GLS (2019) - Function of recovery mode - 2

NOTE Risk of damage due to the vehicle moving up and down

When free driving mode is activated, the vehicle moves up and down. Vehicle parts may be damaged if the underbody bottoms out.

Mercedes-Benz GLS (2019) - Function of recovery mode - 3

Make sure that there is sufficient ground clearance when rocking free mode is activated.

Rocking free mode is a function of the suspension which can assist the driver on loose surfaces (e.g. sand, snow) when freeing a vehicle which has become stuck.

The vehicle body rocks in slow, vertical motions when recovery mode has been activated. This temporarily puts the wheels under greater load, which means they have increased traction and the vehicle is freed.

You can activate free driving mode via Off-road Assist ( page 304).

Function of individual wheel control

Mercedes-Benz GLS (2019) - Function of individual wheel control - 1

WARNING Risk of becoming trapped due to the vehicle lowering

Mercedes-Benz GLS (2019) - Function of individual wheel control - 4

Make sure that the vehicle has sufficient room to move when the individual

wheel control function has been activated.

Individual wheel control is a function of the sus pension, which can be used to set the vehicle level for each wheel individually. This can help to improve alignment of the body when driving off-road.

You can activate individual wheel control via Off-road Assist ( page 304).

Adjusting the vehicle level (vehicles with E-ACTIVE BODY CONTROL)

⚠ WARNING Risk of accident because vehicle level is too high

If you drive at a higher vehicle level, the driving characteristics may be impaired due to the higher vehicle centre of gravity.

The vehicle can drift outwards, for example, when steering or cornering.

Always choose a vehicle level which is suited to the driving style and the road surface conditions.

WARNING Risk of entrapment from vehicle lowering

When lowering the vehicle, other people could become trapped if their limbs are between the vehicle body and the tyres or underneath the vehicle.

Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches when the vehicle is being lowered.

⚠ WARNING Risk of becoming trapped due to the vehicle lowering

Vehicles with AIRMATIC or level control: 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.

Parking Assist PARKTRONIC

Function of Parking Assist PARKTRONIC

Parking Assist PARKTRONIC is an electronic parking assistance system with ultrasound. It monitors the area around your vehicle using six sensors on the front bumper and six sensors the rear bumper. Parking Assist PARKTRONIC shows you the distance between your vehicle and a detected obstacle visually and audibly.

Parking Assist PARKTRONIC is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe manoeuvring and parking remains with you. Make sure that there are no persons, animals or objects in the manoeuvring area while manoeuvring and parking in/exiting parking spaces.

In the standard setting, an intermittent warning tone sounds from a distance of approximately 0.3 m to an obstacle in front and approximately

1.0 m to an obstacle behind. A continuous warning tone sounds from a distance of approximately 0.2 m. Using the Warn early all-round setting in the multimedia system, the warning tones for front and side impact protection can be set to sound at a greater distance of approximately 1.0 m in front and 0.6 m on the sides ( page 310).

① The Warn early all-round setting is always active in the rear of the vehicle.

If Parking Assist PARKTRONIC is deactivated, Active Parking Assist is unavailable.

Function of the passive side impact protection

Passive side impact protection is an additional Parking Assist PARKTRONIC function which warns the driver about obstacles at the side of the vehicle. A warning is issued when obstacles are detected between the front and rear detection range. In order for an object on the side to be detected, the sensors in the front and rear bumper must first detect the object while you are driving past it.

During the parking procedure or manoeuvring, objects are detected as the vehicle drives past. If you steer in the direction of a detected obstacle and there is a risk of a lateral collision, a warning is issued. The segments on the sides light up yellow or red, depending on the distance to the obstacle.

Segment colour depending on distance

Colour Lateral distance
YellowApprox. 30 - 60 cm
RedApprox. < 30 cm

In order for lateral front or rear segments to be displayed, the vehicle must first travel a distance of at least half of the vehicle length. Once the vehicle has travelled the length of the vehicle, all

of the lateral front and rear segments can be displayed.

Function of Trailer Manoeuvring Assist

! NOTE Damage to trailers with a stabilisation device against swerving

In the case of trailers with a stabilisation device against swerving, the trailer or trailer tow hitch could be damaged.

If a trailer coupling with Trailer Manoeuvring Assist is used, only use trailers without a stabilisation device against swerving.

NOTE Damage due to overhanging loads in front or drawbar installations

The vehicle and the trailer may be damaged during manoeuvring due to overhanging loads at the front of the trailer or drawbar installations.

Pay attention to overhanging loads or drawbar installations while manoeuvring.

Trailer Manoeuvring Assist assists you when reversing with a trailer. By means of a turning angle sensor in the trailer coupling, Trailer Manoeuvring Assist monitors the articulation angle between the vehicle and trailer and adjusts it to a specified value.

You can either enter the articulation angle value directly via the multimedia system or use a straightening manoeuvre. When carrying out a

straightening manoeuvre, the system calculates the articulation angle automatically and straightens the vehicle/trailer combination to the trailer's current direction.

Trailer Manoeuvring Assist must be taught-in before it can adjust the articulation angle ( page 311).

Observe the notes on towing a trailer ( page 337).

System limits

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

- The gradient is more than approximately 15%.

Using Trailer Manoeuvring Assist Requirements:

• The vehicle has been started.
• A trailer has been detected.

Adjusting the articulation angle of the trailer

Select

The articulation angle can be changed on the media display or on the touchpad.

Swipe left or right to change the articulation angle.
The maximum articulation angle depends on the length of the trailer. This is calculated by the system by driving the vehicle forwards, including cornering. Before the length of the trailer has been calculated, the maximum articulation angle is approximately 23^ . The longer the trailer is, the higher the maximum articulation angle (max. approximately 60^ ).
▶ Set the desired articulation angle.

When the articulation angle entered has been reached, the drawbar is locked by the system so that the angle is maintained.

Activating the straightening manoeuvre

Select

The system calculates the articulation angle in such a way that the direction of the trailer

at the time of activation is maintained. There Reversing camera

The 360° Camera is a system that consists of four cameras. The cameras cover the immediate vehicle surroundings. The system assists you, e.g. when parking or at exits with reduced visibility.

The views of the 360° Camera are always available when driving forwards up to a speed of approximately 16 km/h and when reversing.

The 360° Camera is only an aid and may show distorted view of obstacles, show them incorrectly or not show them at all. It is not a substitute for your attention to the surroundings. The responsibility for safe manoeuvring and parking remains with you. Make sure that there are no persons, animals or objects etc., in the manoeuvring area while manoeuvring and parking. The system evaluates images from the following cameras:

  • Reversing camera
  • Front camera
  • Two side cameras in the outside mirrors

Active Parking Assist

Function of Active Parking Assist

Active Parking Assist is an electronic parking assistance system which uses ultrasound and is automatically activated during forward travel. The system is operational at speeds below approximately 35 km/h.

If all requirements are met, the □ display appears in the multifunction display. The system then independently locates and measures parallel and perpendicular parking spaces on both sides of the vehicle.

When Active Parking Assist has detected parking spaces, the P display appears in the mu

function display. The arrows show on which side of the road detected parking spaces are located. They are then shown in the media display. The parking space and, if necessary, the parking direction can be selected as desired. Active Parking Assist calculates a suitable vehicle path, switches on the turn signal indicator and assist you in parking and exiting the parking space.

Active Parking Assist provides assistance when changing gear, accelerating, braking and steering the vehicle.

Active Parking Assist is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe manoeuvring and parking remains with you. Make sure that no persons, animals or objects etc. are in the manoeuvring range.

Active Parking Assist is cancelled if, among other things, one of the following actions is carried out:

  • Parking Assist PARKTRONIC is deactivated.
    • Active Parking Assist is deactivated.
  • You begin steering.
  • You apply the parking brake.

  • You engage transmission position [P].

  • ESP® intervenes.
  • You open the doors or the tailgate while driving.

System limits

Objects located above or below the detection range of Parking Assist PARKTRONIC or Active Parking Assist are not detected when the parking space is being measured. These are also not taken into account when the parking manoeuvre is calculated, e.g. overhanging loads, overhangs or loading ramps of lorries, or the boundaries of parking spaces. In some circumstances, Active Parking Assist may therefore guide you into the parking space prematurely.

Mercedes-Benz GLS (2019) - System limits - 1

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.
- Vehicles with automatic transmission: The vehicle may not stop in front of these objects.

This could cause a collision.

In these situations, do not use Active Parking Assist.

Snowfall or heavy rain may lead to a parking space being measured inaccurately. Parking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly. Only use Active Parking Assist on level, high-grip ground.

Do not use Active Parking Assist in the following situations:

  • In extreme weather conditions such as ice, packed snow or in heavy rain.
  • When transporting a load that protrudes beyond the vehicle.
  • If the parking space is on a steep downhill or uphill gradient.
  • When snow chains are fitted.

Active Parking Assist may also display parking spaces that are not suitable for parking, e.g. the following:

  • Parking spaces where parking is prohibited.
  • Parking spaces on unsuitable surfaces.

Active Parking Assist will not assist you with parking spaces at right angles to the direction of travel in the following situations:

  • If two parking spaces are located immediately next to each other.
  • If the parking space is immediately next to a low obstacle such as a kerb.

Active Parking Assist will not assist you with parking spaces parallel or at right angles to the direction of travel in the following situations:

• If the parking space is on a kerb.
- If the parking space is bordered by an obstacle, e.g. a tree, a post or a trailer.

Mercedes-Benz GLS (2019) - Function of Drive Away Assist - 1

WARNING Risk of accident caused by limited detection performance of Drive Away Assist

Drive Away Assist cannot always clearly identify objects and traffic situations.

In such cases, Drive Away Assist might:

  • Warn you without reason and limit the vehicle speed.
  • Not warn you or not limit the vehicle speed.
    Always pay careful attention to the traffic situation; do not rely on Drive Away Assist alone.
    Be prepared to brake or swerve as necessary, provided the traffic situation permits and that it is safe to take evasive action.

Drive Away Assist is only an aid. It is not a substitute for your attention to the surroundings. The responsibility for safe manoeuvring and parking remains with you. Make sure that no persons, animals or objects etc. are in the manoeuvring range.

A risk of a collision may arise in the following situations, for example:

- If the driver mixes up the accelerator and brake pedals.

• If the wrong gear is selected.

Drive Away Assist is active under the following conditions:

• If Parking Assist PARKTRONIC is activated.
- Every time the gear is changed to [R] or D when the vehicle is at a standstill.
- If the detected obstacle is less than approx. 1.0 m away.
- If the manoeuvring assistant function is activated in the multimedia system.

ATTENTION ASSIST

Function of ATTENTION ASSIST

ATTENTION ASSIST assists you on long, monotonous journeys, e.g. on motorways and trunk roads. If ATTENTION ASSIST detects indicators of fatigue or increasing lapses in concentration on the part of the driver, it 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 Instrument Dis-

play. 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.

Mercedes-Benz GLS (2019) - Function of ATTENTION ASSIST - 1

text_image Attention Assist Last break 02:35 h ago

You can have the following status information for ATTENTION ASSIST displayed in the assistance menu of the on-board computer:

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

  • the fuller the circle, the higher the attentional level determined

  • as your attention wanes, the circle in the centre of the display becomes smaller

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 Instrument Display, the multimedia system offers to search for a rest area. You can select a rest area and start navigation to this rest area. This function can be activated and deactivated in the multimedia system.

If ATTENTION ASSIST is deactivated, the symbol appears in the assistance graphic in the Instrument Display when the engine is running. ATTENTION ASSIST is activated automatically when the engine is re-started. The last selected sensitivity level remains stored.

System limits

ATTENTION ASSIST is active in the 60 km/h to 200 km/h speed range.

The functionality of ATTENTION ASSIST is restricted, and warnings may be delayed or not occur at all in the following situations:

  • 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 time has been set incorrectly.
  • In active driving situations, if you change lanes and vary your speed frequently.

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

• If you switch off the engine.
- If you unfasten your seat belt and open the driver's door (e.g. changing drivers or taking a break).

Blind Spot Assist and Active Blind Spot Assist with exit warning

Function of Blind Spot Assist and Active Blind Spot Assist with exit warning

Blind Spot Assist and Active Blind Spot Assist use two lateral, rear-facing radar sensors to monitor the area up to 40 m behind and 3 m next to your vehicle.

If a vehicle is detected at speeds above approximately 12 km/h and this vehicle subsequently enters the monitoring range directly next to your vehicle, the warning lamp in the outside mirror lights up red.

If a vehicle is detected close to the side of your vehicle, the red warning lamp in the outside mirror flashes. If you switch on the turn signal indicator in the corresponding direction, a warning tone sounds once. If the turn signal indicator remains switched on, all other detected vehicles are indicated only by the flashing of the red warning lamp.

If you overtake a vehicle quickly, no warning is given.

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.

As a result, 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.

Blind Spot Assist and Active Blind Spot Assist are only aids. They may fail to detect some vehicles and are no substitute for attentive driving. Always ensure that there is sufficient distance to the side for other road users and obstacles.

Exit warning

The exit warning is an additional function of Blind Spot Assist and can warn vehicle occupants about approaching vehicles when leaving the vehicle when stationary.

Mercedes-Benz GLS (2019) - Exit warning - 1

WARNING Risk of accident despite exit warning

The exit warning reacts neither to stationary objects nor to vehicles approaching you at a greatly different speed.

As a result, 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 there is a vehicle in the monitoring range, this is indicated in the outside mirror. If a vehicle occupant opens the door on the side with the warning, a warning tone sounds and the warning lamp in the outside mirror starts to flash.

This additional function is only available when Blind Spot Assist is activated and up to a number of three minutes after the ignition has been switched off. The exit warning is no longer available once the warning lamp in the outside mirror flashes three times.

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:

- 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 lane

Warnings may be issued in error when driving close to crash barriers or similar solid lane borders. Always make sure that there is sufficient distance to the side for other traffic or obstacles.

Warnings may be interrupted when driving alongside long vehicles, for example lorries, for a prolonged time.

Blind Spot Assist is not operational when reverse gear is engaged.

Blind Spot Assist is not operational when a trailer is coupled to the vehicle and the electrical connection has been correctly established.

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 slowly moving objects

Function of brake application (Active Blind Spot Assist)

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 is carried out. This is designed to help you avoid a collision.

The course-correcting brake application is available in the speed range between approximately 30 km/h and 200 km/h.

A 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.

WARNING Risk of accident despite Active Blind Spot Assist

Active Blind Spot Assist does not react to the following:

  • if vehicles overtake too closely on the side, placing them in the blind spot area
  • vehicles approaching and overtaking you at a greatly different speed

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

Always pay careful attention to the traffic situation and maintain a safe distance at the side of the vehicle.

natural_image Top-down view of two cars with a circular icon labeled '1' and an 'i' button, no visible text or symbols on the cars or background.

If a course-correcting brake application occurs, the red warning lamp flashes in the outside mirror and a warning tone sounds. In addition, a display ① indicating the danger of a side collision appears in the multifunction display.

In rare cases, the system may make an inappropriate brake application. This brake application

may be interrupted at any time if you steer slightly in the opposite direction or accelerate.

System limits

Either a course-correcting brake application appropriate to the driving situation, or none at all, may occur in the following situations:

• Vehicles or obstacles, e.g. crash barriers, are located on both sides of your vehicle.
• A vehicle approaches too closely on the side.
- You have adopted a sporty driving style with high cornering speeds.
- You brake or accelerate significantly.
- A driving safety system intervenes, e.g. ESP® or Active Brake Assist.

- ESP ^ is deactivated.

- A loss of tyre pressure or a defective tyre is detected.

- You are driving with a trailer and the electrical connection to the trailer hitch has been correctly established.

Active Lane Keeping Assist

Function of Active Lane Keeping Assist

Mercedes-Benz GLS (2019) - Active Lane Keeping Assist - 1

natural_image Line drawing of a car front view with a magnified inset showing a hand holding a black object (no text or symbols)

Active Lane Keeping Assist monitors the area in front of your vehicle by means of multifunction camera ①. It serves to protect you against unintentionally leaving your lane. You will be warned by vibration pulses in the steering wheel and guided by a course-correcting brake application back into your lane.

You are warned by vibration pulses in the steering wheel in the following circumstances:

• Active Lane Keeping Assist detects a lane marking.
- A front wheel drives over this lane marking.

You will also be guided back into your lane by means of a course-correcting brake application if the following conditions are met:

• Active Lane Keeping Assist detects lane markings on both edges of the lane.
- A front wheel drives over a solid lane marking.

You can activate or deactivate the Active Lane Keeping Assist warning.

The status of Active Lane Keeping Assist is displayed in the on-board computer:

  • 7:\ (green): Active Lane Keeping Assist activated and operating.
  • ☐: (grey): Active Lane Keeping Assist is activated, but not operating.
  • ☐: Active Lane Keeping Assist is deactivated or there is a malfunction.

Active Lane Keeping Assist can neither reduce the risk of an accident if you fail to adapt your driving style nor override the laws of physics. It cannot take into account road, weather or traffic conditions. Active Lane Keeping Assist is only an aid. You are responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.

Active Lane Keeping Assist can bring the vehicle back into the lane with a lane-correcting brake application. In the case of a broken lane marking being detected, a brake application will only be made if a vehicle has been detected in the adjacent lane. Oncoming traffic can be detected.

Vehicles with Driving Assistance Package or Driving Assistance Plus Package: overtaking vehicles and vehicles in adjacent lanes can also be detected.

Vehicles without Driving Assistance Package or Driving Assistance Plus Package: a lane-correcting brake application also takes place when, in addition to a broken lane marking, the edge of a firm road surface is detected (e.g. central reservation).

Active Lane Keeping Assist is available in the speed range between 60 km/h and 200 km/h.

The availability of the following function is country-dependent.

A lane-correcting brake application also occurs in the Sensitive setting in the following situations:

• Active Lane Keeping Assist detects a solid lane marking.
- A front wheel drives over this lane marking.

System limits

No lane-correcting brake application occurs in the following situations:

  • You clearly and actively steer, brake or accelerate.
  • You have switched on the turn signal indicator (situation-dependent).
  • 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.
  • When ESP ^ is deactivated.
  • When driving with a trailer, the electrical connection to the trailer has been correctly established.
  • If a loss of tyre pressure or a defective tyre has been detected and displayed.

The system may be impaired or may not function. If the carriageway is very narrow and winding in the following situations:

  • If there is poor visibility, e.g. due to insufficient illumination of the road, if there are highly variable shade conditions or in rain, snow, fog or heavy spray.
  • If there is glare, e.g. from oncoming traffic, the sun or reflections.
  • If the windscreen in the area of the multifunction camera is dirty, or if the camera misted up, 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 cannot be detected.
  • If the lane markings change quickly, e.g. lanes branch off, cross one another or merge.

Vehicles without Driving Assistance Package or Driving Assistance Plus Package: Active Lane Keeping Assist uses radar sensors to monitor several areas around the vehicle. If the radar sensors in the rear bumper are dirty or covered with snow, the system may be impaired or may not function. If an obstacle in the lane in which you are driving has been detected, no lane-correcting brake application occurs.

text_image Technical diagram of a car rear bumper with labeled parts and an inset showing a mechanical component detail.

Trailer hitch (example with additional guide pin)

Depending on the bicycle rack's design, different numbers of bicycles can be transported.

The following bicycle rack designs are possible:

- When mounted by attaching to the ball head Ⓞ, the maximum load capacity is 75 kg. Up to three bicycles can be transported.

- When mounted on the ball head ① and guide pin ②, the maximum load capacity 100 kg. Up to four bicycles can be transported.

The load capacity is calculated from the weight of the bicycle rack and the bicycle rack load.

The vehicle's driving characteristics will change when a bicycle rack is fitted. Adapt your driving style accordingly. Drive carefully and maintain safe distance.

When using a bicycle rack, set the tyre pressure for increased load on the rear axle of the vehicle. Further information on the tyre pressure can be found in the tyre pressure table ( page 607).

Notes on loading

The larger the distance between the load's centre of gravity and the ball head, the greater the load on the trailer hitch.

Observe the following notes:

- Mount heavy bicycles as close to the vehicle as possible.

the Always distribute the load on the bicycle rack is as evenly as possible across the vehicle's longitudinal axis.

Mercedes-Benz recommends removing all detachable parts from bicycles (e.g. baskets, child seats, rechargeable batteries) before loading them onto the bicycle rack. This will improve the aerodynamic resistance and centre of gravity of the bicycle rack.

Always secure the bicycles to prevent them from moving around and check them at regular intervals to ensure that they are secure.

Do not use tarpaulins or other covers. The driving characteristics and rear view may be impaired. In addition, aerodynamic resistance and the load on the trailer hitch will increase.

Notes on operating safety

⚠ WARNING Risk of distraction from information systems and communications equipment

If you operate information and communication equipment integrated in the vehicle when driving, you will be distracted from the traffic situation. This could also cause you to lose control of the vehicle.

▶ Only operate this equipment when the traffic situation permits.
If you cannot be sure of this, stop the vehicle whilst paying attention to road and traffic conditions and operate the equipment with the vehicle stationary.

WARNING Risk of an accident from operating mobile communication equipment while the vehicle is in motion

Mobile communications devices distract the driver from the traffic situation. This could

also cause the driver to lose control of the vehicle.

As the driver, only operate mobile communications devices when the vehicle is stationary.
As a vehicle occupant, only use mobile communications devices in the areas intended for this purpose, e.g. in the rear passenger compartment.

⚠ WARNING Risk of injury due to objects being stowed incorrectly

If objects in the vehicle interior are stowed incorrectly, they can slide or be thrown around and hit vehicle occupants. In addition, cup holders, open stowage spaces and mobile phone receptacles cannot always retain all objects they contain.

There is a risk of injury, particularly in the event of sudden braking or a sudden change in direction.

Always stow objects so that they cannot be thrown around in such situations.
Always make sure that objects do not protrude from stowage spaces, luggage nets or stowage nets.
Close the lockable stowage spaces before starting a journey.
▶ Always stow and secure heavy, hard, pointed, sharp-edged, fragile or bulky objects in the boot/load compartment.

For your own safety, always observe the following points when operating mobile communications equipment and especially your voice control system:

  • Observe the legal requirements for the country in which you are driving.
  • While driving, only operate mobile communications equipment and your voice control system when the traffic conditions permit it. You may otherwise be distracted from the traffic conditions and cause an accident, injuring yourself and others.

  • If you use the voice control system in an emergency your voice can change and your telephone call, e.g. an emergency call, can thereby be unnecessarily delayed.

  • Familiarise yourself with the voice control system functions before starting the journey.
  • Comply with the loading guidelines ( page 144).

Operation

Overview of operating the multifunction steering wheel

LINGUATRONIC is operational approximately thirty seconds after the ignition is switched on.

3 Press the rocker switch down: 📞 rejects/ends a call (ends the dialogue)

Conducting a dialogue

For the dialogue with LINGUATRONIC, you can use complete sentences of colloquial language as voice commands, such as, for example, "Please show me the list of the last calls" or "How warm is it outside?". It is not necessary to first change to the relevant application such as "Telephone" or "Vehicle function".

To activate or continue dialogue by using a keyword: say "Hello Mercedes" to activate LINGUATRONIC. Voice activation must be switched on in the multimedia system (→ page 363). For this, it is not necessary to press up the rocker switch on the multifunction steering wheel. Voice activation can also be directly combined with a voice command, e.g. "Hi Mercedes, how fast can I drive?".

Press the □ rocker switch up on the multifunction steering wheel. You can say a voice command after an acoustic signal.

To correct an entry: say the Correction voice command.
To select an entry from the selection list: say the line number or the contents.
To browse the selection list: say the Next or Back voice command.
To interrupt the dialogue: say the Pause voice command. The dialogue can be continued with the "Hello Mercedes" voice command or by pressing up the rocker switch on the multifunction steering wheel.
To jump to the preceding dialogue: say the Back voice command.
To jump back to the top dialogue level: say the Home voice command.
To cancel the dialogue: say the Close voice command or press the 📄 or 🏠 button on the multifunction steering wheel.

To interrupt a voice output: speak in the middle of a voice dialogue when the system is still answering. The voice output is shortened and the conclusion is reached more quickly.

The Voice barge-in option must be switched on in the multimedia system for this (→ page 363).

Switching on voice interruption

▶ Select Voice barge-in. If the function is active, a command can be interjected during voice output of the system.

Using LINGUATRONIC effectively

LINGUATRONIC audible help functions

mUsing the corresponding voice commands you receive the following information and assistance in the following cases:

  • For optimal operation: say the Voice control tutorial voice command or call up the Digital Owner's Manual with Could you go to the LINGUATRONIC tutorial please?, for example. The full extent of the Digital Owner's Manual is available when the vehicle is stationary. Here you can also find explanatory videos which introduce you to the functions of LINGUATRONIC.
  • Current application: on the multifunction steering wheel, press the rocker switch up and say the Help voice command. You will

receive suggestions and information about operation of LINGUATRONIC for the current application.

  • Continued dialogue: say the Help voice command during a voice dialogue. For every step of the dialogue you receive matching information.
  • Specific function: say the voice command for the desired function, e.g. with "Hello Mercedes, I need help with the radio" or after pressing the rocker switch on the multifunction steering wheel up, say the Help for the telephone voice command, for example.

Notes on optimal use of LINGUATRONIC

Notes on how to improve recognition:

  • Activate online voice control (→ page 363).
  • Only operate LINGUATRONIC from the driver's seat.
  • Say the voice commands coherently and clearly, but do not exaggerate the words.
  • Avoid loud noises that cause interference while making a voice command entry, e.g.

the entertainment in the rear-passenger compartment.

• For telephone or address book entries:

  • Only create sensible address book entries in the system/mobile phone, e.g. enter surname and first name in the correct field.
  • Do not use any abbreviations, unnecessary spaces or special characters.
  • For radio or TV programme names: say the Read out station list voice command and say the desired station name in the way the voice output reads aloud to you.
    To improve recognition, depending on the outside temperature, either the blowers for ventilation or heating are reduced when LIN GUATRONIC is started.

Notes on online voice control

Online voice control improves recognition and makes additional results available as a result of external information, e.g. information about POIs

and about the weather. We therefore recommend that you activate online voice control.

You will need a Mercedes me user account for this. If you do not yet have a user account you have to create one and connect it with your vehicle ( page 509).

Then call up your Mercedes me user account. The Mercedes me services are shown and can be activated ( page 509).

In addition, online voice control must be activated ( page 363).

Essential voice commands

Notes on the voice commands

Aside from the exact voice commands (see the "Voice command" column in the following tables) to call up specific functions, in most cases LIN-GUATRONIC also understands a great many paraphrases from daily usage. Examples of these are listed in the "Colloquial examples" column. For some languages however these examples are only available to a limited extent.

Content in angled brackets, e.g. or , is a placeholder which has to be completed by you with the desired term. The voice command Set as intermediate

destination could, for example, be completed with: Set Mercedes-Benz Arena as intermediate destination.

Overview of switch voice commands

Switch voice commands can be used to open certain applications.

Notes on route guidance

⚠ WARNING Risk of distraction from operating integrated communication equipment while the vehicle is in motion

If you operate communication equipment integrated in the vehicle when driving, you will be distracted from the traffic situation. This could also cause you to lose control of the vehicle.

Only operate this equipment when the traffic situation permits.
If you cannot be sure of this, stop the vehicle whilst paying attention to road and traffic conditions and operate the equipment with the vehicle stationary.

You must observe the legal requirements for the country in which you are currently driving when operating the multimedia system. Route guidance begins once a route has been calculated.

The road and traffic rules and regulations always have priority over multimedia system driving instructions.

Driving instructions are:

• Navigation announcements
- Route guidance displays
• Lane recommendations

If you do not follow the driving instructions or if you leave the calculated route, a new route is calculated automatically.

Driving instructions may differ from the actual road and traffic conditions if:

• The route is diverted
- The direction of a one-way street has been changed

For this reason, you must always observe road and traffic rules and regulations during your journey as well as the prevailing traffic conditions.

The route may differ from the ideal route due to the following:

- Roadworks

• Incomplete digital map data

Notes on GPS reception

The correct function of the navigation system depends amongst other things on GPS reception. In certain situations GPS reception can be impaired, defective or even not possible, e.g. in tunnels or in multi-storey car parks.

Changing direction overview

Changes of direction are shown in the following displays:

  • Detailed image of the junction The display appears when you drive into a junction.
    • 3D image The display appears when driving on junction-free, multi-lane roads, for example on motorway exits and motorway interchanges.

There are three phases when changing direction:

- Preparation phase

If there is enough time between the changes of direction, the multimedia system prepares you for the upcoming change of direction. A navigation announcement is issued depending on the settings for driving recommendations, e.g. "Prepare to turn right".

Select navigation announcements for driving recommendations ( page 445).

The map appears in full-screen mode. The status line shows: the direction information or the name of the road which is to be turned into and the distance to the change of direction.

- Announcement phase

The multimedia system announces the upcoming change of direction depending on the settings for driving recommendations, e.g. by announcing "In 200 m at the end of the street turn right into Station Road".

The display is split into two parts. The map is displayed on the left; on the right, there is a detailed image of the junction or a 3D image of the upcoming change of direction.

• Change-of-direction phase

Car-to-X-Communication

Car-to-X-Communication overview

The following requirements apply for using Car-to-X-Communication:

- The vehicle is equipped with a multimedia system featuring navigation and a communication module with an activated, integrated SIM card.

• Car-to-X-Communication is activated.

Car-to-X-Communication is available in selected countries.

The communication module automatically establishes an Internet connection once the ignition switched on. If there are any hazard warnings, they will be provided shortly thereafter. Depending on the mobile phone connection, the provision takes place from within a second up to about a minute.

Benefits of Car-to-X-Communication:

  • Hazards are recognised automatically in the background by the vehicle or may be reported by the driver. These are then sent to vehicles with Car-to-X-Communication in the immediate vicinity.
  • If available, current details relating to hazard spots near the vehicle's current position are received.

This gives you sufficient time to adapt your driving style to the traffic conditions.

The use of Car-to-X-Communication requires the regular transmission of vehicle data to Daimler AG. The data is then immediately pseudonymised by Daimler AG. The vehicle data is deleted after an appropriate amount of time has elapsed (several weeks) and is not stored permanently.

Data which serves as identification is replaced during the pseudonymisation process. In this way, your identity is protected against access by unauthorised third parties.

Mercedes-Benz emergency call system

Information on available emergency call systems

Two types of emergency call system are available to you in the vehicle:

• Mercedes-Benz emergency call system

112 emergency call system (EU eCall)

The following applies for both emergency call systems:

  • The transfer of specific data is required for the intended function of both emergency call systems. This will be explained in the "Data transfer" section ( page 513).
  • Both emergency call systems are included as standard equipment in your vehicle and are activated at the factory.
  • The use of both emergency call systems is exempt from charges.

- Both emergency call systems only function in areas in which the wireless service providers offer mobile phone coverage.

For both systems, insufficient network coverage from the wireless service providers can result in an emergency call not being transmitted.

Differences between the Mercedes-Benz emergency call system and 112 emergency call system (EU eCall)

Mercedes-Benz emergency call system112 emergency call system (EU eCall)
The Mercedes-Benz emergency call system is permanently logged in to the mobile phone network.Automatic and manual Mercedes-Benz emergency calls are transmitted to a Mercedes-Benz emergency call centre.In the event that the emergency call centre of the Mercedes-Benz emergency call system cannot be reached (e.g. due to a lack of network coverage), the 112 emergency call is carried out automatically.If you decide on the 112 emergency call system (EU eCall), then the system only logs in to the mobile phone network after the triggering of a manual or automatic emergency call.The 112 emergency call system (EU eCall) transmits automatic and manual emergency calls directly to public coordination centres.

The 112 emergency call system (EU eCall) in your vehicle meets the delegated regulation EU 2017/79. Proper and full functionality of the 112 emergency call system (EU eCall) depends on circumstances beyond the influence of Daimler AG. This includes mobile network coverage and the technical infrastructure of the public reception centres in the respective countries.
Please observe that in the event of a repair genuine Mercedes-Benz batteries must be used which have been certified pursuant to the delegated regulation EU 2017/79

(Appendix I). Other manufacturers are also permitted provided their batteries are certified according to the delegated regulation EU 2017/79.

You can find more information on the regional availability of the Mercedes-Benz emergency call system at: https://www.mercedes-benz-mobile.com/extra/ecall/

There is the option of deactivating the Mercedes-Benz emergency call system and using only the 112 emergency call system (EU eCall). Contact address for carrying out deacti-

vation of the Mercedes-Benz emergency call sys- tem are the local dealers.

Mercedes-Benz recommends the activation of the Mercedes-Benz emergency call system for the following reasons:

- In emergency situations when abroad, you can also get support in a language you speak.

- Several transmission technologies are used to accelerate the transfer of the accident data and improve reliability of the transmission.

- The Mercedes-Benz emergency call system is permanently logged in to the mobile phone network, which ensures faster placement of the emergency call and faster transfer of the accident data.

Measures for rescue, recovery or towing away can then be initiated in quickly.

- With a Mercedes-Benz emergency call, the accident data is only transferred to the public coordination centre with the approval of the customer.

In the event of an automatically triggered emergency call in which there is no voice contact, the accident data is transmitted immediately to the public emergency call centre.

- Should the Mercedes-Benz emergency call centre not be available, the 112 emergency call is carried out automatically.

Overview of emergency call systems

Both the Mercedes-Benz emergency call system as well as the 112 emergency call system (EU eCall) can help to reduce the time between an accident and the arrival of emergency services

at the site of the accident. They help locate an accident site in places that are difficult to access.

Both emergency call systems can initiate an emergency call automatically ( page 512) 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

The following messages appear in the media display of both emergency call systems:

- SOS NOT READY: the ignition is not on or there is a malfunction with the emergency call system. This does not necessarily indicate complete failure of the emergency call system. Emergency calls call still be transmitted.

The display only refers to the vehicle and does not take account of the availability of mobile phone networks and the Mercedes-Benz emergency call centre.

The functional readiness of the emergency call system on the vehicle can be seen when the SOS NOT READY display disappears once the ignition is switched on.

- SOS: The icon appears in the display during an active emergency call.

If there is a malfunction in the emergency call system (e.g. a fault with the speaker, microphone, airbag, SOS button), a corresponding message appears in the multifunction display of the instrument cluster.

Triggering an automatic emergency call Requirements:

• The ignition is switched on.
• The starter battery is sufficiently charged.

Both the Mercedes-Benz emergency call system as well as the 112 emergency call system (EU eCall) automatically initiate an emergency call in the following situations:

• After an automatically initiated emergency stop by Active Emergency Stop Assist.

The emergency call has been made:

  • A voice connection is established with the emergency call centre.
  • A message with accident data is transmitted to the emergency call centre.

The SOS button in the overhead control panel flashes until the emergency call is finished.

If no connection can be made to the public emergency services, a corresponding message appears in the display.

Dial the 112 emergency number or an appropriate local emergency call number on your mobile phone.

If an emergency call has been initiated:

- Remain in the vehicle if the road and traffic conditions permit you to do so until a voice connection is established with the emergency call centre.

  • On the basis of the call, the emergency call centre decides whether it is necessary to call rescue teams and/or the police to the accident site.
  • If no vehicle occupant answers, an ambulance is sent to the vehicle immediately.

Triggering a manual emergency call

To use the SOS button in the overhead control panel: press the SOS button at least one second long ( page 505).

Emergency call system data transmission

For both the Mercedes-Benz emergency call system as well as the 112 emergency call system (EU eCall) data is transferred to the Mercedes-Benz emergency call centre or the public emergency call centre.

Depending on the emergency call system activated ( page 510) different data is transmitted to the appropriate emergency call centre.

Transferred data according to activated emergency call system:

Function of the ASSYST PLUS service interval display

The ASSYST PLUS service interval display on the instrument display provides information on the remaining time or distance before the next service due date.

You can hide this service display using the back button on the left-hand side of the steering wheel.

Depending on how the vehicle is used, the ASSYST PLUS service interval display may shorten the service interval, e.g. in the following cases:

• mainly short-distance driving
- when the engine is often left idling for long periods
• in the event of frequent cold start phases
- vehicles with a diesel particulate filter: in the event of frequently interrupted regeneration of the diesel particulate filter

Mercedes-Benz recommends avoiding such operating conditions.

You can obtain information concerning the servicing of your vehicle from a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

Displaying the service due date

On-board computer:

Service ▶ ASSYST PLUS

The next service due date is displayed.

To exit the display: press the back button on the left-hand side of the steering wheel.

Information on regular maintenance work

NOTE Premature wear through failure to observe service due dates

Service work which is not carried out at the right time or incompletely can lead to increased wear and damage to the vehicle.

▶ Always observe the prescribed service intervals.
▶ Always have the prescribed service work carried out at a qualified specialist workshop.

Special service requirements

The prescribed service interval is based on normal operation of the vehicle. Maintenance work will need to be performed more often if the vehicle is operated under arduous conditions or increased loads.

The ASSYST PLUS service interval display is only an aid. The driver of the vehicle bears responsibility as regards to whether maintenance work needs to be performed more often than speci-

fied based on the actual operating conditions and/or loads.

Examples of arduous operating conditions:

  • regular city driving with frequent intermediate stops
    • mainly short-distance driving
  • frequent operation in mountainous terrain or on poor road surfaces
  • when the engine is often left idling for long periods
    • operation in particularly dusty conditions and/or if air-recirculation mode is frequently used

In these or similar operating conditions, have the interior air filter, engine air cleaner, engine oil and oil filter etc. changed more frequently. The tyres must be checked more frequently if the vehicle is operated under increased loads. Further information can be obtained at a qualified specialist workshop.

Battery disconnection periods

The ASSYST PLUS service interval display can only calculate the service due date when the battery is connected.

Note down the service due date displayed on the instrument display before disconnecting the battery ( page 565).

Notes on regularly inspecting wheels and tyres

Mercedes-Benz GLS (2019) - Notes on regularly inspecting wheels and tyres - 1

WARNING Risk of accident from damaged tyres

Damaged tyres can cause tyre pressure loss. As a result, you could lose control of your vehicle.

▶ Check the tyres regularly for signs of damage and replace any damaged tyres immediately.

WARNING Risk of aquaplaning due to insufficient tyre tread

Insufficient tyre tread will result in reduced tyre grip. The tyre tread is no longer able dissipate water.

This means that in heavy rain or slush the risk of aquaplaning is increased, in particular where speed is not adapted to suit the conditions.

If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at different locations on the tyre tread.

Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tyres.

Minimum tread depth for:

• Summer tyres: 3 mm
- M+S tyres: 4 mm
For safety reasons, replace the tyres before the legally prescribed limit for the minimum tread depth is reached.

to Carry out the following checks on all wheels regularly, at least once a month or as required, e.g. prior to a long journey or driving off-road:

  • Check the tyre pressure (→ page 606).
  • Visually inspect wheels and tyres for damage.
  • Check the valve caps.

The valves must be protected against moisture and dirt by the valve caps approved especially for your vehicle by Mercedes-Benz.

- Visual check of the tyre tread depth and the tyre contact surface across the entire width. The minimum tread depth for summer tyres is 3 mm and for winter tyres 4 mm.

Tyre pressure

Notes on tyre pressure

Mercedes-Benz GLS (2019) - Notes on tyre pressure - 1

WARNING Risk of accident due to insufficient or excessive tyre pressure

Underinflated or overinflated tyres pose the following risks:

- The tyres may burst, especially as the load and vehicle speed increase.

  • The tyres may wear excessively and/or unevenly, which may greatly impair tyre traction.
  • The driving characteristics, as well as steering and braking, may be greatly impaired.
    Comply with the recommended tyre pressure and check the tyre pressure of all tyres including the spare wheel regularly:
    • at least once a month
  • when the load changes
    • before embarking on a longer journey
  • if operating conditions change, e.g. off-road driving
    Adjust the tyre pressure as necessary.

Tyre pressure which is too high or too low can:

  • Shorten the service life of the tyres.
  • Cause increased tyre damage.
  • Adversely affect driving characteristics and thus driving safety, e.g. due to aquaplaning.

Mercedes-Benz GLS (2019) - Notes on tyre pressure - 2

WARNING Risk of accident from repeated tyre pressure drop

If the tyre pressure drops repeatedly, the wheel, valve or tyre may be damaged.

Insufficient tyre pressure can cause the tyres to burst.

Inspect the tyre for signs of foreign objects.
▶ Check whether the wheel or valve has a leak.
If you are unable to rectify the damage, contact a qualified specialist workshop.

Information on the recommended tyre pressure for the vehicle's factory-fitted tyres can be found on the tyre pressure table on the inside of the fuel filler flap ( page 607).

Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure.

Vehicles with a tyre pressure monitoring system: you can also check the tyre pressure using the on-board computer.

Only correct tyre pressures when the tyres are cold. Conditions for cold tyres:

  • The vehicle has been parked with the tyres out of direct sunlight for at least three hours.
    • The vehicle has travelled less than 1.6 km.

A rise in the tyre temperature of 10 °C increases the tyre pressure by approx. 10 kPa (0.1 bar/1.5 psi). Take this into account when checking the tyre pressure of warm tyres.

Notes on trailer operation

Always inflate the rear axle tyres to the recommended tyre pressures on the tyre pressure table for increased load.

Tyre pressure table

Mercedes-Benz GLS (2019) - NOTE Vehicle and tyre damage through tyre types and sizes that have not been approved - 11

WARNING Risk of accident with high performance tyres

The special tyre tread in combination with the optimised tyre compound, means that

the risk of skidding or hydroplaning on wet roads is increased.

In addition, the tyre grip is greatly reduced at a low outside temperature and tyre running temperature.

Switch on the ESPand adapt your driving style accordingly.
▶ Use M+S tyres at outside temperatures of less than 50 °F.

Observe the following when selecting, fitting and replacing tyres:

  • Country-specific requirements for tyre approval that define a specific tyre type for your vehicle.
    Furthermore, the use of certain tyre types in certain regions and areas of operation can be highly beneficial.

- Only use tyres and wheels of the same type (summer tyres, winter tyres, MOExtended tyres) and the same make.

- Only fit wheels of the same size on one axle (left and right).

It is only permissible to fit a different wheel size in the event of a flat tyre in order to drive to the specialist workshop.

- Only fit tyres of the correct size onto the wheels.

- Do not make any modifications to the brake system, the wheels or the tyres.

- Only fit tyres of the correct size onto the wheels. - Do not make any modifications to the brake system, the wheels or the tyres.

The use of shims or brake dust shields is not permitted and may invalidate the vehicle's general operating permit.

- Vehicles with a tyre pressure monitoring system: all fitted wheels must be equipped with functioning sensors for the tyre pressure monitoring system.

- At temperatures below 7 °C, use winter tyres or all-season tyres marked M+S for all wheels.

- Vehicles with a tyre pressure monitoring system: all fitted wheels must be equipped with functioning sensors for the tyre pressure monitoring system. - At temperatures below 7 °C, use winter tyres or all-season tyres marked M+S for all wheels.

Winter tyres bearing the snowflake symbol in addition to the M+S marking provide the best possible grip in wintry road conditions.

For M+S tyres, only use tyres with the same tread.

  • Observe the maximum permissible speed for the M+S tyres fitted.
    If this is below the vehicle's maximum speed, this must be indicated by an appropriate label in the driver's field of vision.
    Run in new tyres at moderate speeds for the first 100 km.

- Replace the tyres after six years at the latest, regardless of wear.

- When replacing with tyres that do not feature run-flat characteristics: vehicles with MOExtended tyres are not equipped with a TREFIT kit at the factory. Equip the vehicle with a TREFIT kit after replacing with tyres that do not feature run-flat characteristics, e.g. winter tyres.

- Replace the tyres after six years at the latest, regardless of wear. - When replacing with tyres that do not feature run-flat characteristics: vehicles with MOExtended tyres are not equipped with a TREFIT kit at the factory.

Notes on interchanging wheels

Mercedes-Benz GLS (2019) - Notes on interchanging wheels - 1

WARNING Risk of injury through different wheel sizes

Interchanging the front and rear wheels if the wheels or tyres have different dimensions may severely impair the driving characteristics.

The disk brakes or wheel suspension components may also be damaged.

Rotate front and rear wheels only if the wheels and tyres are of the same dimensions.

Interchanging the front and rear wheels if the wheels or tyres have different dimensions can render the general operating permit invalid.

The wear patterns on the front and rear wheels differ:

  • Front wheels wear more on the shoulder of the tyre
  • Rear wheels wear more in the centre of the tyre

Do not drive with tyres that have too little tread depth. This significantly reduces traction on wet roads (aquaplaning).

On vehicles with the same front and rear wheel size, you can interchange the wheels every 5,000 to 10,000 km, depending on the wear. Ensure the direction of rotation is maintained for the wheels.

Observe the instructions and safety notes on "Changing a wheel" when doing so ( page 619).

Notes on storing wheels

When storing wheels, observe the following notes:

  • After removing wheels, store them in a cool, dry and preferably dark place.
  • Protect the tyres from contact with oil, grease or fuel.

AdBlue®

Notes on AdBlue®

Observe the notes on operating fluids ( page 635).

AdBlue ^® is a water-soluble fluid for the NOx exhaust gas aftertreatment of diesel engines.

It may be improper or punishable in some countries to operate a vehicle that uses no AdBlue ^® or one that does not comply with the specifications of these operating instructions.

NOTE Malfunctions due to the dilution of AdBlue® or the use of additive-enhanced AdBlue®

The function of the NOx exhaust gas after-treatment can be impaired by the use of unsuitable denoxification agents.

Only use AdBlue® in accordance with ISO 22241.
Do not dilute AdBlue with water.
Do not use additive-enhanced AdBlue®

NOTE Damage and malfunctions due to impurities in AdBlue®

Consequences of impurities in AdBlue®

• increased emission values
• damage to the catalytic converter

  • NOx exhaust gas aftertreatment malfunctions
    Avoid impurities in AdBlue®

AdBlue ^® residues crystallise after a period of time, and contaminate the surfaces with which they come into contact. Clean the dirty surfaces with water as soon as possible.

When you open the AdBlue ^® tank, small amounts of ammonia vapour may escape. Do not inhale any ammonia vapours that may be released. Only fill the AdBlue ^® tank in well-ventilated areas.

AdBlue ^® capacity

Total capacity of AdBlue ^® tank

ModelT
All models 31.6 litres

AdBlue® consumption

The average AdBlue® consumption is between 1% and 5% of fuel consumption. Like fuel con-

sumption, AdBlue ^® consumption is highly dependent upon driving style and operating conditions. For this reason, your vehicle's actual consumption figures under day-to-day operating conditions may differ from the consumption figures calculated. The frequency at which you will have to top up AdBlue ^® will also vary. Have the AdBlue ^® supply checked at a qualified specialist workshop before making journeys outside of Europe. Before a longer stay outside of Europe, consult a qualified specialist workshop.

AdBlue ^® range and fill level

The AdBlue ^® fill level and range can be displayed via the on-board computer. The AdBlue range shown depends strongly on the driving style and operating conditions. The actual range can therefore deviate from the range currently dis-ralled in the on-board computer. The information supplied in the Owner's Manual regarding the reserve quantity at the first display warning and on the minimum top-up quantity when the tank is empty is also to be understood as guide values.

Display the AdBlue range and level ( page 351).

Fording depth

Mercedes-Benz GLS (2019) - Fording depth - 1

NOTE Damage caused by water when fording

Water can enter the engine compartment and vehicle interior if:

  • you exceed the maximum permissible fording depth when driving through standing water
    • a bow wave forms during fording
  • water accumulates during fording of flowing water
    Do not exceed the maximum permissible fording depth and drive slowly through the water.

The specified value indicates the maximum permissible fording depth for:

  • vehicles that are ready to drive – fuel tank full, all fluids topped up, with driver
    • slow driving through standing water

Driving through flowing water reduces the permissible fording depth due to the accumulation of water.

Observe the notes on off-road driving and ford-ing ( page 218).

Warning and indicator lamps

Overview of indicator and warning lamps

Some systems will perform a self-test when the ignition is switched on. Some indicator and warning lamps may briefly light up or flash. This behaviour is non-critical. These indicator and

warning lamps indicate a malfunction only if they light up or flash after the engine has been started or during a journey.
