Frequently Asked Questions - 428i Convertible (2016) BMW

How do I open and close the retractable hardtop?
Press and hold the hardtop button inside the vehicle at walking speed. Ensure the trunk partition is folded down and trunk lid is closed. The hardtop can also be operated via Comfort Access from outside using the remote control.
What should I do if my remote control battery dies?

How do I check and reset the Tire Pressure Monitor (TPM)?
Check tire pressures when cold and inflate to the values on the driver's door pillar. After correcting pressures, initialize TPM via iDrive: 'Vehicle info' > 'Vehicle status' > 'TPM' > 'Reset'. Drive a few minutes to complete.
What type of engine oil is recommended and how do I check the level?
Use BMW Longlife-01 approved oils, typically 0W-30 or 5W-30. Check oil level electronically via iDrive: 'Vehicle info' > 'Vehicle status' > 'Engine oil level'. Add oil only when the level is below minimum.
Can I use run-flat tires on this vehicle?
Yes, the 428i Convertible may come equipped with run-flat tires (RSC). In case of a puncture, you can continue driving at reduced speed (up to 50 mph) for a limited distance. Do not exceed 50 mph and avoid sharp maneuvers.

ADDENDUM TO OWNER'S MANUAL

We wanted to provide you with some updates and clarifications with respect to the printed BMW Owner's Manual. These updates and clarifications will supersede the materials contained in that document.

  1. Where the terms “service center,” “the service center,” “your service center,” “service specialist,” or “service” are used in the Owner's Manual, we wanted to clarify that the terms refer to a BMW dealer's service center or another service center or repair shop that employs trained personnel that can perform maintenance and repair work on your vehicle in accordance with BMW specifications.

  2. Where the text of the Owner's Manual contains an affirmative instruction to contact a "service center" or "your service center," we wanted to clarify that BMW recommends that, if you are faced with one of the situations addressed by that text, you contact or seek the assistance of a BMW dealer's service center or another service center or repair shop that employs trained personnel that can perform maintenance and repair work on your vehicle in accordance with BMW specifications.

While BMW of North America LLC, at no cost to you, will pay for repairs required by the limited warranties provided with respect to your vehicle and for maintenance under the Maintenance Program during the applicable warranty and maintenance coverage periods, you are free to elect, both during those periods and thereafter, to have maintenance and repair work provided by other service centers or repair shops.

  1. Where the Owner's Manual makes reference to parts and accessories having been approved by BMW, those references are intended to reflect that those parts and accessories are recommended by BMW of North America LLC. You may elect to use other parts and accessories, but, if you do,

we recommend that you make sure that any such parts and/or accessories are appropriate for use on your vehicle.

  1. At page 7, under the warranty section's discussion of homologation, where it states that you “cannot lodge warranty claims for your vehicle there,” the text should read that you “may not be able to lodge warranty claims for your vehicle there.”

  2. At page 7, under the “Parts and accessories” section, in the sixth sentence, the word “cannot” should read “does not.”

  3. At page 56, in the “Check and replace safety belts” section, the text beginning, “This should only be done by your service center …” should be disregarded and the following text should be read in lieu thereof: “BMW recommends having this work performed by a service center as it is important that this safety feature functions properly.”

  4. At page 90, under the heading: “Special windshield,” the paragraph beginning, “Therefore, have the special windshield …” should be disregarded and the following text should be read in lieu thereof: “BMW recommends that you have the special windshield replaced by the service center.”

  6. At page 99, in the “Triggered rollover protection system” section, the sentence beginning, “Have this work performed only by our service center …” should be disregarded and the following text should be read in lieu thereof: “BMW recommends

having this work performed by a service center as it is important that this safety feature functions properly."

  1. At page 169 under the heading: “Objects within the range of movement of the pedals” and at page 224 under the heading: “Carpets and floor mats,” the paragraph that begins: “Only use floor mats …” should be disregarded and the following language should be read in lieu thereof: “The manufacturer of your vehicle recommends that you use floor mats that have been identified by it as appropriate for use in your vehicle and that can be properly fixed in place.”

  2. At page 174, under the heading: “Have maintenance carried out,” the sentence beginning, “The maintenance should be carried out …” should be disregarded and the following text should be read in lieu thereof: “BMW recommends that you have the maintenance carried out by your service center.”

  3. At page 186, under the heading “Tire inflation specifications,” the sentence beginning, “Tire inflation pressure specifications apply to approved tire sizes …” should be disregarded.

  4. At page 192, under the heading: “Mounting,” the paragraph beginning, “Have mounting and balancing …” should be disregarded and the following text should be read in lieu thereof: “BMW recommends that you have mounting and balancing performed by your service center or a tire mounting specialist.”

  5. At page 193, under the heading: “Approved wheels and tires,” the term “Approved” should be disregarded and in lieu thereof, the term “Recommended” should be read in its place. In addition, the text of that section should be disregarded and the following text should be read in lieu thereof:

The manufacturer of your vehicle strongly suggests that you use wheels and tires that have been recommended by the vehicle

manufacturer for your vehicle type; otherwise, for example, despite having the same official size ratings, variations can lead to body contact and with it, the risk of severe accidents.

The manufacturer of your vehicle does not evaluate non-recommended wheels and tires to determine if they are suitable for use on your vehicle.

  1. At page 197, under the heading: “Snow Chains,” the text should be disregarded and the following text should be read in lieu thereof:

Only certain types of fine-link snow chains have been tested by the manufacturer of your vehicle and are determined by the manufacturer of your vehicle to be road safe and are recommended by the manufacturer of your vehicle.

Information about recommended snow chains is available from a service center.

  1. At page 200, under the heading “Hood,” the sentence beginning, “If you are unfamiliar” should be disregarded.

  2.

i Indicates that you should consult the relevant section of this Owner's Manual for information on a particular part or assembly.

Vehicle features and options

This Owner's Manual describes all models and all standard, country-specific and optional equipment that is offered in the model series. Therefore, in this Owner's Manual, we also describe and illustrate features that are not available in your vehicle, e.g., because of the selected optional features or the country-specific version.

This also applies to safety-related functions and systems.

The respectively applicable country provisions must be observed when using the respective features and systems.

For any options and equipment not described in this Owner's Handbook, refer to the Supplementary Owner's Handbooks.

On right-hand drive vehicles, some controls are arranged differently from what is shown in the illustrations.

Status of the Owner's Manual

Basic information

The manufacturer of your vehicle pursues a policy of constant development that is conceived to ensure that our vehicles continue to embody the highest quality and safety standards. In rare cases, therefore, the features described in this Owner's Manual may differ from those in your vehicle.

Updates made after the editorial deadline

Any updates made after the editorial deadline for the Owner's Manuals are found in the appendix of the printed Quick Reference for the vehicle.

For your own safety

Warranty

Your vehicle is technically configured for the operating conditions and registration requirements applying in the country of first delivery - homologation. If your vehicle is to be operated in a different country it might be necessary to adapt your vehicle to potentially differing operating conditions and permit requirements. If your vehicle does not comply with the homologation requirements in a certain country you cannot lodge warranty claims for your vehicle there. Further information can be obtained from your Service Centre.

Maintenance and repairs

Advanced technology, e.g., the use of modern materials and high-performance electronics, requires suitable maintenance and repair work. Therefore, have this work performed only by a BMW center or a workshop that works according to BMW repair procedures with appropriately trained personnel.

If work is not carried out properly, there is a danger of subsequent damage and related safety hazards.

Parts and accessories

BMW recommends using parts and accessories approved by BMW for this purpose.

Your BMW center is the right contact for genuine BMW parts and accessories, other products approved by BMW and related qualified advice.

BMW has tested these products for safety and suitability in relation to BMW vehicles.

BMW can assume responsibility for them.

However, we cannot assume any responsibility whatsoever for parts and accessories that have not been specifically approved by BMW.

BMW cannot evaluate whether each individual product from another manufacturer can be used with BMW vehicles without presenting a safety hazard. This guarantee does not apply when country-specific government approval has been granted. Testing of this kind may fail to embrace the entire range of potential operating conditions to which components might be exposed on BMW vehicles. Such products could conceivably fail to comply with BMW's own stringent quality standards.

California Proposition 65 Warning

California laws require us to state the following warning:

Engine exhaust and a wide variety of automobile components and parts, including components found in the interior furnishings in a vehicle, contain or emit chemicals known to the State of California to cause cancer and birth defects and reproductive harm. In addition, certain fluids contained in vehicles and certain products of component wear contain or emit

chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Battery posts, terminals and related accessories contain lead and lead compounds. Wash your hands after handling. Used engine oil contains chemicals that have caused cancer in laboratory animals. Always protect your skin by washing thoroughly with soap and water.

Service and warranty

We recommend that you read this publication thoroughly. Your vehicle is covered by the following warranties:

▶ New Vehicle Limited Warranty.
▶ Rust Perforation Limited Warranty.
▶ Federal Emissions System Defect Warranty.
▶ Federal Emissions Performance Warranty.
▶ California Emission Control System Limited Warranty.

Detailed information about these warranties is listed in the Service and Warranty Information Booklet for US models or in the Warranty and Service Guide Booklet for Canadian models.

Your vehicle has been specifically adapted and designed to meet the particular operating conditions and homologation requirements in your country and continental region in order to deliver the full driving pleasure while the vehicle is operated under those conditions. If you wish to operate your vehicle in another country or region, you may be required to adapt your vehicle to meet different prevailing operating conditions and homologation requirements. You should also be aware of any applicable warranty limitations or exclusions for such country or region. In such case, please contact Customer Relations for further information.

Maintenance

Maintain the vehicle regularly to sustain the road safety, operational reliability and the New Vehicle Limited Warranty. Specifications for required maintenance measures:

▶ BMW Maintenance system
▶ Service and Warranty Information Booklet for US models
▶ Warranty and Service Guide Booklet for Canadian models

If the vehicle is not maintained according to these specifications, this could result in serious damage to the vehicle. Such damage is not covered by the BMW New Vehicle Limited Warranty.

Data memory

Many electronic components on your vehicle are equipped with data memories that temporarily or permanently store technical information about the condition of the vehicle, events and faults. This technical information generally records the state of a component, a module, a system or the environment:

▶ Operating mode of system components, fill levels for instance.
▶ Status messages for the vehicle and from its individual components, e.g., wheel rotation speed/vehicle speed, deceleration, transverse acceleration.
Malfunctions and faults in important system components, e.g., lights and brakes.
▶ Responses by the vehicle to special situations such as airbag deployment or engaging the stability control system.
▶ Ambient conditions, such as temperature.
This data is purely technical in nature and is used to detect and correct faults and to optimize vehicle functions. Motion profiles over routes traveled cannot be created from this data. When service offerings are used, e.g., repair services, service processes, warranty claims, quality assurance, this technical information can be read out from the event and fault memories by the service personnel, in-

cluding the manufacturer, using special diagnostic tools. You can obtain further information there if you need it. After an error is corrected, the information in the fault memory is deleted or overwritten on a continuous basis.

With the vehicle in use there are situations where you can associate these technical data with individuals if combined with other information, e.g., an accident report, damage to the vehicle, eye witness accounts — possibly with the assistance of an expert.

Additional functions that are contractually agreed with the customer - such as vehicle emergency locating - you can transmit certain vehicle data from the vehicle.

Event Data Recorder EDR

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

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

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

These data can help provide a better understanding of the circumstances in which crashes and injuries occur.

EDR data are recorded by your vehicle only if a nontrivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data, e.g., name, gender, age, and crash location, are recorded.

However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

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

Vehicle identification number

Close-up of a mechanical component with visible pipes and housing (no text or symbols)

The vehicle identification number can be found in the engine compartment.

The vehicle identification number can also be found behind the windshield.

Reporting safety defects

For US customers

The following only applies to vehicles owned and operated in the US.

If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration NHTSA, in addition to notifying BMW of North America, LLC, P.O. Box 1227, West-

wood, New Jersey 07675-1227, Telephone 1-800-831-1117.

If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign.

However, NHTSA cannot become involved in individual problems between you, your dealer, or BMW of North America, LLC.

To contact NHTSA, you may call the Vehicle Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153); go to http://www.safercar.gov; or write to: Administrator, NHTSA, 400 Seventh Street, SW., Washington, DC 20590. You can also obtain other information about motor vehicle safety from http://www.safercar.gov.

For Canadian customers

Canadian customers who wish to report a safety-related defect to Transport Canada, Defect Investigations and Recalls, may call the toll-free hotline 1-800-333-0510. You can also obtain other information about motor vehicle safety from http://www.tc.gc.ca/roadsafety.

Personal Profile

The concept

Personal Profile provides three profiles, using which personal vehicle settings can be stored. Every remote control has one of these profiles assigned.

If the vehicle is unlocked using a remote control, the assigned personal profile will be activated. All settings stored in the profile are automatically applied.

If several drivers use their own remote control, the vehicle will adjust the personal settings during unlocking. These settings are also restored, if the vehicle has been used in the

meantime by a person with a different remote control.

Changes to the settings are automatically saved in the personal profile.

Three personal profiles and a guest profile can be created.

Adjusting

The settings for the following systems and functions are saved in the active profile. The scope of storable settings is country- and equipment-dependable.

▶ Unlocking and locking.
▶ Lights.
▶ Climate control.
Radio.
▶ Instrument cluster.
▶ Programmable memory buttons.
▶ Volumes, tone.
▶ Control Display.
▶ Navigation.
▶ Park Distance Control PDC.
▶ Rearview camera
▶ Side View.
▶ Head-up Display.
▶ Driving Dynamics Control.
▶ Cruise control.
▶ Intelligent Safety.
▶ Active Blind Spot Detection.

Adaptive Light Control

The concept

Adaptive Light Control is a variable headlight control system that enables dynamic illumination of the road surface.

Depending on the steering angle and other parameters, the light from the headlight follows the course of the road.

In tight curves, e.g., on mountainous roads or when turning, one of the two front fog lights is switched on as a turning lamp. As a result the inside of the curve is better lighted.

Activating

Position of switch with the ignition switched on.

To avoid blinding oncoming traffic, the Adaptive Light Control does not swivel to the driver's side when the vehicle is at a standstill.

The turning lights are automatically switched on depending on the steering angle or the use of turn signals.

When driving in reverse, the turning lights may be automatically switched on regardless of the steering angle.

Malfunction

A Check Control message is displayed.

Adaptive Light Control is malfunctioning or has failed. Have the system checked as soon as possible.

High-beam Assistant

The concept

When the low beams are activated, this system automatically switches the high beams on and off or suppresses the light in the areas that blind oncoming traffic. The procedure is controlled by a camera on the front of the interior rearview mirror. The assistant ensures that the high beams are activated whenever the traffic situation allows. The driver can intervene at any time and switch the high beams non and off as usual.

Note

3 Side airbag
4 Knee airbags

Front airbags

Front airbags help protect the driver and front passenger by responding to frontal impacts in which safety belts alone would not provide adequate restraint.

Side airbags

In a lateral impact, the side airbag supports the side of the body in the chest, lap, and head area.

Knee airbag

The knee airbag supports the legs in a frontal impact.

Protective action

Airbags are not triggered in every impact situation, e.g., in less severe accidents or rear-end collisions.

BMW 428i Convertible (2016) - Protective action - 1

Information on how to ensure the optimal protective effect of the airbags

▶ Keep at a distance from the airbags.
▶ Always grasp the steering wheel on the steering wheel rim, holding your hands at the 3 o'clock and 9 o'clock positions, to keep the risk of injury to your hands or arms as low as possible when the airbag is triggered.
There should be no person, animals, or objects between an airbag and a person.
Do not use the cover of the front airbag on the front passenger side as a storage area.
▶ Dashboard and windshield on the front passenger side must stay clear - do not attach adhesive labels or coverings and do not attach brackets or cables, e. g., for GPS devices or' mobile phones.
▶ Make sure that the front passenger is sitting correctly, i.e., keeps his or her feet and legs in the footwell; otherwise, leg injuries might occur when front airbag is activated.
Do not place slip covers, seat cushions or other objects on the front passenger seat that are not approved specifically for seats with integrated side airbags.
Do not hang pieces of clothing, such as jackets, over the backrests.
▶ Make sure that occupants keep their heads away from the side airbag; otherwise, injuries might occur when airbag is activated.
Do not remove the airbag system.
Do not remove the steering wheel.
Do not apply adhesive materials to the air-bag cover panels, do not cover them or modify them in any way.
▶ Never modify either the individual components or the wiring in the airbag system. This also applies to steering wheel covers, the dashboard, and the seats.

Even when you follow all instructions very closely, injury from contact with the airbags cannot be ruled out in certain situations.

The ignition and inflation noise may lead to short-term and, in most cases, temporary hearing impairment in sensitive individuals.

BMW 428i Convertible (2016) - Protective action - 2

Malfunction, deactivation and after deploying the airbags

Do not touch the individual components immediately after the system has been triggered; otherwise, you may risk burns.

Only have the airbags checked, repaired or dismantled and the airbag generator scrapped by the service center or an authorized repair shop for handling explosives.

Non-professional attempts to service the system could lead to failure in an emergency or unintentional activation of the airbag - both may lead to injury.

Warnings and information on the airbags are also found on the sun visors.

Functional readiness of the airbag system

BMW 428i Convertible (2016) - Functional readiness of the airbag system - 1

Child restraint fixing system in the front passenger seat

Before transporting a child on the front passenger seat, refer to the safety notes and instructions for children on the front passenger seat, see Children.

Malfunction of the automatic deactivation system

When transporting older children and adults, the front-seat passenger airbags may be deactivated in certain sitting positions. In this case, the indicator lamp for the front-seat passenger airbags lights up.

In this case, change the sitting position so that the front-seat passenger airbags are activated and the indicator lamp goes out.

If it is not possible to activate the airbags, have the person sit in the rear.

To enable correct recognition of the occupied seat cushion

Do not attach covers, cushions, ball mats or other items to the front passenger seat unless they are specifically recommended by your vehicle's manufacturer.
Do not place any electronic devices on the passenger seat if a child restraint system is to be installed on it.

Do not place objects under the seat that could press against the seat from below.
▶ No moisture in or on the seat.

Indicator lamp for the front-seat passenger airbags

The indicator lamp for the front-seat passenger airbags indicates the operating state of the front-seat passenger airbags.

The lamp indicates whether the airbags are either activated or deactivated.

BMW 428i Convertible (2016) - Indicator lamp for the front-seat passenger airbags - 2

The indicator lamp lights up when a child is properly seated in a child restraint fixing system or when the seat is empty. The airbags on the front passenger side are not activated.

The indicator lamp does not light up when, e.g., a correctly seated person of sufficient size is detected on the seat. The airbags on the front passenger side are activated.

Detected child seats

The system generally detects children seated in a child seat, particularly in child seats required by NHTSA when the vehicle was manufactured. After installing a child seat, make sure that the indicator lamp for the front-seat passenger airbags lights up. This indicates that the child seat has been detected and the front-seat passenger airbags are not activated.

Strength of the driver's and front-seat passenger airbag

The explosive power that activates driver's/front passenger's airbags very much depends on the positions of the driver's/front passenger's seat.

With a respective message appearing on Control Display calibrate the front seats to keep the accuracy of this function over the long-term.

Calibrating the front seats

A corresponding message appears on the Control Display.

  1. Press the reel and move the respective seat all the way forward.
  2. Press the reel forward again. The seat still moves forward slightly.
  3. Readjust the seat to the desired position.

The calibration procedure is completed when the message on the Control Display disappears.

If the message continues to be displayed, repeat the calibration.

If the message does not disappear after a repeat calibration, have the system checked as soon as possible.

BMW 428i Convertible (2016) - Calibrating the front seats - 1

Unobstructed area of movement

Ensure that the area of movement of the seats is unobstructed to avoid personal injury or damage to objects.

Rollover protection system

The concept

The rollover protection system is automatically activated in the event of a sufficiently serious accident or if the longitudinal axis is tilted excessively. The safety frames located behind the rear headrests extend within fractions of a second.

Supplementing the reinforced front windshield frame, the rollover protection system further increases passenger safety.

Hints

  1. Push the safety frame down, arrow 2.
  2. Release the release lever only if the safety frame was pushed back almost completely.
  3. Push the safety frame down until it noticeably engages. To do this, the safety frame must be pressed far into its holder; high levels of force are required.

BMW 428i Convertible (2016) - Do not move hardtop - 2

Do not bend via the safety frame

Should the safety frame not have snapped in place when it is released, then it moves back up with jerking movements. When it is released, do not bend via the safety frame; otherwise, there is a risk of injury with a safety frame that is not engaged.

Slowly reduce pressure on the safety frame in order to test whether it is latched.

  1. Proceed likewise with the second safety frame.

Malfunction

BMW 428i Convertible (2016) - Malfunction - 1

A Check Control message is displayed when there is a malfunction.

Tire Pressure Monitor TPM

The concept

The system monitors tire inflation pressure in the four mounted tires. The system warns you if there is a significant loss of pressure in one or more tires. For this purpose, sensors in the tire valves measure the tire inflation pressure and tire temperature.

Hints

BMW 428i Convertible (2016) - Hints - 1

Tire damage due to external factors

Sudden tire damage caused by external circumstances cannot be recognized in advance.

With use of the system observe further information found under Tire inflation pressure, refer to page 186.

Functional requirements

The system must have been reset with the correct tire inflation pressure; otherwise, reliable signaling of tire inflation pressure loss is not assured.

Reset the system after each adjustment of the tire inflation pressure and after every tire or wheel change.

Always use wheels with TPM electronics to ensure that the system will operate properly.

Status display

The current status of the Tire Pressure Monitor TPM can be displayed on the Control Display, e.g., whether or not the TPM is active.

On the Control Display:

  1. "Vehicle info"

  2. "Vehicle status"

  3. "Tre Pressure Monitor (TPM)"

The status is displayed.

Status control display

Tire and system status are indicated by the color of the wheels and a text message on the Control Display.

All wheels green

System is active and will issue a warning relative to the tire inflation pressures stored during the last reset.

One wheel is yellow

A flat tire or major drop in inflation pressure in the indicated tire.

All wheels are yellow

A flat tire or major drop in inflation pressure in several tires.

Wheels, gray

The system cannot detect a flat tire. Reasons for this may be:

The system is being reset.
▶ Malfunction.

Status information

The status control display additionally shows the current tire inflation pressures and, depending on the model, tire temperatures. It shows the actual values read; they may vary depending on driving style or weather conditions.

Carry out reset

Reset the system after each adjustment of the tire inflation pressure and after every tire or wheel change.

On the Control Display and on the vehicle:

  1. "Vehicle info"
  2. "Vehicle status"
  3. "Perform reset"
  4. Start the engine - do not drive off.
  5. Reset tire inflation pressure:"Perform reset".
  6. Drive away.

The tires are shown in gray and the status is displayed.

After driving faster than 19 mph/30 km/h for a short period, the set tire inflation pressures are accepted as reference values. The reset is completed automatically while driving.

After a successfully completed Reset, the wheels on the Control Display are shown in green and "Tire Pressure Monitor (TPM) active" is displayed.

You may interrupt this trip at any time. When you continue the reset resumes automatically.

Low tire pressure message

BMW 428i Convertible (2016) - Low tire pressure message - 1

The yellow warning lamp lights up. A Check Control message is displayed.

There is a flat tire or a major loss in tire inflation pressure.

No reset was performed for the system. The system therefore issues a warning based on the tire inflation pressures before the last reset.

  1. Reduce your speed and stop cautiously. Avoid sudden braking and steering maneuvers.
  2. Check whether the vehicle is fitted with regular tires or run-flat tires.

Run-flat tires, refer to page 194, are labeled with a circular symbol containing the letters RSC marked on the tire's sidewall.

BMW 428i Convertible (2016) - Low tire pressure message - 2

Do not continue driving without run-flat tires

Do not continue driving if the vehicle is not equipped with run-flat tires; continued driving may result in serious accidents.

A low tire inflation pressure might turn on DSC Dynamic Stability Control.

Actions in the event of a flat tire

Normal tires

  1. Identify the damaged tire.

Do this by checking the air pressure in all four tires.

The tire pressure gage of the Mobility System, refer to page 194, can possibly be used for this purpose.

If the tire inflation pressure in all four tires is shown to be correct, it is possible that the Tire Pressure Monitor did not perform a reset. Then perform the reset.

If an identification is not possible, please contact the service center.

  1. Fixing a flat tire, where applicable with the Mobility System.

Use of tire sealant, e.g., the Mobility System, may damage the TPM wheel electronics. In this case, have the electronics checked at the next opportunity and have them replaced if needed.

Run-flat tires

Maximum speed

You may continue driving with a damaged tire at speeds up to 50 mph/80 km/h.

Continued driving with a flat tire

If continuing to drive with a damaged tire:

  1. Avoid sudden braking and steering maneuvers.
  2. Do not exceed a speed of 50 mph/80 km/h.

  3. Check the air pressure in all four tires at the next opportunity.

If the tire inflation pressure in all four tires is shown to be correct, it is possible that the Tire Pressure Monitor did not perform a reset. In that case, carry out a reset.

Possible driving distance with complete loss of tire inflation pressure:

The possible driving distance after a loss of tire inflation pressure depends on cargo load, driving style and road conditions.

A vehicle with an average load has a possible driving range of approx. 50 miles/80 km.

A vehicle with a damaged tire reacts differently, e.g., it has reduced lane stability during braking, a longer braking distance and different self-steering properties. Adjust your driving style accordingly. Avoid abrupt steering maneuvers or driving over obstacles, e.g., curbs, potholes, etc.

Because the possible driving distance depends on how the vehicle is used during the trip, the actual distance may be shorter or longer depending on the driving speed, road conditions, external temperature, cargo load, etc.

BMW 428i Convertible (2016) - Continued driving with a flat tire - 1

Continued driving with a flat tire

Drive moderately and do not exceed a speed of 50 mph/80 km/h.

Your car handles differently when you lose tire inflation pressure, e.g., your lane stability is reduced when braking, braking distances are longer and the self-steering properties will change.

BMW 428i Convertible (2016) - Continued driving with a flat tire - 2

Final tire failure

Vibrations or loud noises while driving can indicate the final failure of a tire. Reduce speed and stop; otherwise, pieces of the tire could come loose and cause an accident. Do not continue driving and contact your service center.

Required tire inflation pressure check message

A Check Control message is displayed in the following situations

The system has detected a wheel change, but no reset was done.
▶ Inflation was not carried out according to specifications.
The tire inflation pressure has fallen below the level of the last confirmation.

In this case:

▶ Check the tire pressure and correct as needed.

- Carry out a reset of the system after a tire change.

System limits

The system does not function properly if a reset has not been carried out, e.g., a flat tire is reported though tire inflation pressures are correct.

The tire inflation pressure depends on the tire's temperature. Driving or exposure to the sun will increase the tire's temperature, thus increasing the tire inflation pressure. The tire inflation pressure is reduced when the tire temperature falls again. These circumstances may cause a warning when temperatures fall very sharply.

The yellow warning lamp flashes and then lights up continuously. A Check Control message is displayed. No flat tire or loss of tire inflation pressure can be detected.

Display in the following situations:

▶ A wheel without TPM electronics is fitted: have the service center check it if needed.
▶ Malfunction: have the system checked by your service center.

▷ TPM was unable to complete the reset. Reset the system again.
▶ Interference through systems or devices with the same radio frequency: after leaving the area of the interference, the system automatically becomes active again.

Declaration according to NHTSA/FMVSS 138 Tire Pressure Monitoring System

Each tire, including the spare (if provided) should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon sub-

sequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction tell-tale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

FTM Flat Tire Monitor

The concept

The system detects tire inflation pressure loss on the basis of rotation speed differences between the individual wheels while driving.

In the event of a tire inflation pressure loss, the diameter and therefore the rotational speed of the corresponding wheel changes. This will be detected and reported as a flat tire.

The system does not measure the actual inflation pressure in the tires.

Functional requirements

The system must have been initialized when the tire inflation pressure was correct; otherwise, reliable flagging of a flat tire is not assured. Initialize the system after each correction of the tire inflation pressure and after every tire or wheel change.

Status display

The current status of the Flat Tire Monitor can be displayed on the Control Display, e.g., whether or not the FTM is active.

On the Control Display:

  1. "Vehicle info"
  2. "Vehicle status"
  3. "Flat Tire Monitor (FTM)"

The status is displayed.

Initialization

When initializing the once set inflation tire pressures serve as reference values in order to detect a flat tire. Initialization is started by confirming the tire inflation pressures.

Do not initialize the system when driving with snow chains.

On the Control Display:

  1. "Vehicle info"
  2. "Vehicle status"
  3. "Perform reset"
  4. Start the engine - do not drive off.
  5. Start the initialization with "Perform reset".
  6. Drive away.

The initialization is completed while driving, which can be interrupted at any time.

The initialization automatically continues when driving resumes.

Indication of a flat tire

BMW 428i Convertible (2016) - Indication of a flat tire - 1

The yellow warning lamp lights up. A Check Control message is displayed.

There is a flat tire or a major loss in tire inflation pressure.

  1. Reduce your speed and stop cautiously. Avoid sudden braking and steering maneuvers.
  2. Check whether the vehicle is fitted with regular tires or run-flat tires.
    Run-flat tires, refer to page 194, are labeled with a circular symbol containing the letters RSC marked on the tire's sidewall.

BMW 428i Convertible (2016) - Indication of a flat tire - 2

Do not continue driving without run-flat tires

Do not continue driving if the vehicle is not equipped with run-flat tires; continued driving may result in serious accidents.

When a flat tire is indicated, DSC Dynamic Stability Control is switched on if needed.

System limits

BMW 428i Convertible (2016) - System limits - 1

Sudden tire damage

Sudden serious tire damage caused by external circumstances cannot be recognized in advance.

A natural, even tire inflation pressure loss in all four tires will not be recognized. Therefore, check the tire inflation pressure regularly.

The system could be delayed or malfunction in the following situations:

▶ When the system has not been initialized.
▶ When driving on a snowy or slippery road surface.
▶ Sporty driving style: spinning traction wheels, high lateral acceleration (drifting).
▶ When driving with snow chains.

Actions in the event of a flat tire

Normal tires

  1. Identify the damaged tire.

Do this by checking the air pressure in all four tires.

The tire pressure gage of the Mobility System, refer to page 194, can possibly be used for this purpose.

If the tire inflation pressure in all four tires is correct, the Flat Tire Monitor may not have been initialized. In this case, initialize the system.

If an identification is not possible, please contact the service center.

  1. Fix the flat tire where applicable using the Mobility System, refer to page 194.

Run-flat tires

Maximum speed

You may continue driving with a damaged tire at speeds up to 50 mph/80 km/h.

Continued driving with a flat tire

If continuing to drive with a damaged tire:

  1. Avoid sudden braking and steering maneuvers.
  2. Do not exceed a speed of 50 mph/80 km/h.
  3. Check the air pressure in all four tires at the next opportunity.
    If the tire inflation pressure in all four tires is correct, the Flat Tire Monitor may not have been initialized. In this case, initialize the system.

Possible driving distance with complete loss of tire inflation pressure:

The possible driving distance after a loss of tire inflation pressure depends on cargo load, driving style and road conditions.

A vehicle with an average load has a possible driving range of approx. 50 miles/80 km.

A vehicle with a damaged tire reacts differently, e.g., it has reduced lane stability during braking, a longer braking distance and different self-steering properties. Adjust your driving style accordingly. Avoid abrupt steering maneuvers or driving over obstacles, e.g., curbs, potholes, etc.

Because the possible driving distance depends on how the vehicle is used during the trip, the actual distance may be shorter or longer depending on the driving speed, road conditions, external temperature, cargo load, etc.

BMW 428i Convertible (2016) - Continued driving with a flat tire - 1

Continued driving with a flat tire

Drive moderately and do not exceed a speed of 50 mph/80 km/h.

Your car handles differently when you lose tire inflation pressure, e.g., your lane stability is reduced when braking, braking distances are longer and the self-steering properties will change.

BMW 428i Convertible (2016) - Continued driving with a flat tire - 2

Final tire failure

Vibrations or loud noises while driving can indicate the final failure of a tire. Reduce speed and stop; otherwise, pieces of the tire could come loose and cause an accident. Do not continue driving and contact your service center.

Intelligent Safety

The concept

Intelligent Safety enables central operation of the driver assistance system.

Depending on how the vehicle is equipped, Intelligent Safety consists of one or more systems that can help prevent a imminent collision. These systems are active automatically every time the engine is started using the Start/Stop button:

▶ Front-end collision warning, refer to page 107.

▶ Pedestrian warning, refer to page 112.

Front-end collision warning

Depending on the equipment, the collision warning system consists of one of the two systems:

▶ Front-end collision warning with City Braking function, refer to page 107.
▶ Front-end collision warning with braking function, refer to page 109

Front-end collision warning with City Braking function

The concept

The system can help prevent accidents. If an accident cannot be prevented, the system will help reduce the collision speed.

The system sounds a warning before an imminent collision and actuates brakes independently if needed.

The automatic braking intervention is done with limited force and duration.

A camera in the area of the rearview mirror controls the system.

The front-end collision warning is available even if cruise control has been deactivated.

With the vehicle approaching another vehicle intentionally the collision warning is delayed avoiding false alarm.

General information

The system warns at two levels of an imminent danger of collision at speeds from approx.

3 mph/5 km/h. Time of warnings may vary with the current driving situation.

Appropriate braking kicks in at speeds of up to 35 mph/60 km/h.

BMW 428i Convertible (2016) - Symbol Measure - 2

The vehicle flashes red and an acoustic signal sounds: acute warning.

You are requested to intervene by braking or make an evasive maneuver.

Prewarning

This warning is issued, e.g., when there is the impending danger of a collision or the distance to the vehicle ahead is too small.

The driver must intervene actively when there is a prewarning.

Acute warning with braking function

Warning of the imminent danger of a collision when the vehicle approaches another object at a relatively high differential speed.

The driver must intervene actively when there is an acute warning. If necessary, the driver is assisted by a minor automatic braking intervention in a possible risk of collision.

Acute warnings can also be triggered without previous prewarning.

Braking intervention

The warning prompts the driver himself/herself to react. During a warning, the maximum braking force is used. Premise for the brake booster is sufficiently quick and hard stepping on the brake pedal. The system can assist with some braking intervention if there is risk of a collision. At low speeds vehicles may thus come to a complete stop.

The braking intervention is executed only if DSC Dynamic Stability Control is switched on and Dynamic Traction Control DTC is activated.

The braking intervention can be interrupted by stepping on the accelerator pedal or by actively moving the steering wheel.

Object detection can be restricted. Limitations of the detection range and functional restrictions are to be considered.

System limits

Detection range

The system's detection potential is limited.

Thus a warning might not be issued or be issued late.

E. g. the following situations may not be detected:

▶ Slow moving vehicles when you approach them at high speed.
▶ Vehicles that suddenly swerve in front of you, or sharply decelerating vehicles.

▶ Vehicles with an unusual rear appearance.
▶ Two-wheeled vehicles ahead of you.

Functional limitations

The system may not be fully functional in the following situations:

In heavy fog, rain, sprayed water or snowfall.
In tight curves.
▶ If the driving stability control systems are limited or deactivated, e.g., DSC OFF.
▶ If, depending on the vehicle equipment version, the field of view of the camera in the mirror or the radar sensor is dirty or obscured.
▶ Up to 10 seconds after the start of the engine, via the Start/Stop knob.
During calibration of the camera immediately after vehicle shipment.
▶ If there is constant blinding effects because of oncoming light, e. g., from the sun low in the sky.

Warning sensitivity

The more sensitive the warning settings are, e.g. the warning time, the more warnings are displayed. However, there may also be an excess of false warnings.

Front-end collision warning with braking function

The concept

The system can help prevent accidents. If an accident cannot be prevented, the system will help reduce the collision speed.

During normal brake application, the outer brake lights light up.
During heavy brake application, the inner brake lights light up in addition.

Attentiveness assistant

The concept

The system can detect increasing lack of alertness or fatigue of the driver during long, monotonous journeys, e.g., on highways. In this situation, it is recommended that the driver takes a break.

Note

BMW 428i Convertible (2016) - Note - 1

Personal responsibility

The system cannot act as a substitute for the personal assessment of one's physical state and may not detect an increasing lack of alertness or fatigue or may not detect it correctly. Therefore, make sure that the driver is rested and alert; otherwise, risks may be detected too late and an accident be caused as a result.

Function

The system is activated each time the engine is started and cannot be switched off.

After travel has begun, the system is trained about the driver, so that increasing lack of alertness or fatigue can be detected.

This procedure takes the following criteria into account:

▶ Personal driving style, e.g., steering behavior.
▶ Driving conditions, e.g., length of trip.

Starting at approximately 43 mph/70 km/h, the system is active and can display a recommendation to take a break.

Break recommendation

If the driver becomes increasingly less alert or fatigued, a message is displayed in the Control Display with the recommendation to take a break.

A recommendation to take a break is displayed only once during an uninterrupted trip.

After a break, another recommendation to take a break cannot be displayed until after approximately 45 minutes.

System limits

The function may be limited in the following situations, for instance, and will either output an incorrect warning or no warning at all:

▷ When the clock is set incorrectly.
When the vehicle speed is mainly below about 43 mph/70 km/h.
▶ With a sporty driving style, such as during rapid acceleration or when cornering fast.
In active driving situations, such as when changing lanes frequently.
▶ When the road surface is poor.
▷ In the event of strong side winds.

Driving stability control systems

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features that are not necessarily available in your car, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. The respectively applicable country provisions must be observed when using the respective features and systems.

Antilock Brake System ABS

ABS prevents locking of the wheels during braking.

The vehicle contains its steering power even during full brake applications, thus increasing active safety.

ABS is operational every time you start the engine.

Brake assistant

When you apply the brakes rapidly, this system automatically produces the greatest possible braking force boost. It reduces the braking distance to a minimum during emergency stop. This system utilizes all of the benefits provided by ABS.

Do not reduce the pressure on the brake pedal for the duration of the emergency stop.

DSC Dynamic Stability Control

The concept

DSC prevents traction loss in the power wheels when driving off and accelerating. DSC also recognizes unstable vehicle conditions such as fishtailing or nose-diving. Within the physical limits DSC helps to keep the vehicle on a steady course by reducing engine speed and by applying brakes to the individual wheels.

Note

BMW 428i Convertible (2016) - Note - 1

Adjust your driving style to the situation. An appropriate driving style is always the possibility of the driver.

The laws of physics cannot be repealed, not even with DSC.

Therefore, do not reduce the additional safety margin by driving in a risky manner.

BMW 428i Convertible (2016) - Note - 2

Do not deactivate DSC when driving with roof load

Do not deactivate Dynamic Stability Control DSC when driving with roof load, e.g. roof-mounted luggage rack.

Otherwise, driving safety is not given in driving-critical situation due to the elevated center of gravity.

DTC Dynamic Traction Control

The concept

The DTC system is a version of the DSC where forward momentum is optimized.

The system ensures maximum headway on special road conditions or loose road surfaces, e.g., unplowed snowy roads, but with somewhat limited driving stability.

Activating the Dynamic Traction Control DTC provides maximum traction. Driving stability is limited during acceleration and when driving in curves.

Therefore drive with appropriate caution.

You may find it useful to briefly activate DTC under the following special circumstances:

▶ When driving in slush or on uncleared, snow-covered roads.
▶ When freeing vehicle from deep snow or driving off from loose grounds.
▶ When driving with snow chains.

xDrive

xDrive is the all-wheel-drive system of your vehicle. Concerted action by the xDrive and DSC further optimize traction and driving dynamics. The xDrive all-wheel-drive system variably distributes the drive forces to the front and rear axles as demanded by the driving situation and road surface.

Dynamic Damping Control

The concept

This system reduces undesirable vehicle motion when using a dynamic driving style or traveling on uneven road surfaces.

The system enhances driving dynamics and comfort fitting road surface and driving style.

Programs

The system offers several different programs. Select the programs via the Driving Dynamics Control, refer to page 121.

SPORT

Consistently sporty control of the shock absorbers for greater driving agility.

SPORT+

Driving off without delay

After releasing the foot brake, start driving without delay, since the drive-off assistant will not hold the vehicle in place for more than approx. 2 seconds and the vehicle will begin to roll back.

Servotronic

The concept

The Servotronic varies the steering force required to turn the wheels in accordance with the vehicle speed. At low speeds, the steering force is strongly supported, i. e. during steering, low force is required. As the speed increases, the assistance of the steering force is reduced.

Furthermore, the steering force adapts according to the driving program, so that a direct, sporty feel and/or comfortable steering is conveyed.

Driving comfort

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features that are not necessarily available in your car, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. The respectively applicable country provisions must be observed when using the respective features and systems.

Active Cruise Control with Stop & Go function, ACC

The concept

Use this system to select a desired speed that the vehicle will maintain automatically on clear roads.

To the extent possible, the system automatically adjusts the speed to a slower vehicle ahead of you.

The distance that the vehicle maintains to the vehicle ahead of you can be varied.

For safety reasons, it depends on the speed.

To maintain a certain distance, the system automatically reduces the speed, applies the brakes lightly, or accelerates again if the vehicle ahead begins moving faster.

If the vehicle ahead of you brakes to a halt, and then proceeds to drive again within a brief period, the system is able to detect this within the given system limits. Your own vehicle will brake automatically and then accelerate again.

If the vehicle ahead of you drives away again after a prolonged period, briefly press the accelerator pedal or press the appropriate button to reactivate the system. The vehicle will automatically accelerate.

As soon as the road is clear, the vehicle accelerates to the desired speed.

The speed is also maintained downhill, but may not be maintained uphill if engine power is insufficient.

General information

Depending on the driving settings, the features of the cruise control can change in certain areas.

Hints

BMW 428i Convertible (2016) - Hints - 1

Personal responsibility

Even an active system holds the driver responsible for his or her driving, particularly for staying in your lane, adjusting your speed, keeping your distance and for your driving style all in relation to traffic.

Technically the system has its limits, it cannot independently react to all traffic situations.

Monitor your driving, be on the alert, observe the vehicle surroundings and other traffic and react when needed, e.g. through braking, steering or make evasive maneuvers - risk of accident.

BMW 428i Convertible (2016) - Hints - 2

Unfavorable weather conditions

In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush, fog or glare, this may result in poorer recognition of vehicles as well as short-term interruptions for vehicles that are already detected. Drive attentively, and react to the current traffic situation. Intervene actively when necessary, e.g., by braking, steering or making an evasive maneuver, otherwise, there is the risk of an accident.

BMW 428i Convertible (2016) - Hints - 3

Before leaving the vehicle, secure it against moving on its own.

BMW 428i Convertible (2016) - Deceleration - 3

Swerving vehicles

If a vehicle driving ahead of you suddenly swerves into your lane, the system may not be able to automatically restore the selected dis-

tance. This also applies to major speed differences to vehicles driving ahead of you, e.g., when rapidly approaching a truck. When a vehicle driving ahead of you is reliably detected, the system requests that the driver intervene by braking and carrying out evasive maneuvers, if needed. You must react yourself; otherwise, there is the risk of an accident.

Unexpected lane change

PDC Park Distance Control

The concept

PDC is a support when parking. When you slowly approach an object in the rear - or also in the front of the vehicle if the feature is available - then the object is reported through:

▷ Signal tones.
▷ Visual display.

General information

Ultrasound sensors in the bumpers measure the distances from objects.

The maneuvering range, depending on the obstacle and environmental conditions, is approx. 6 ft/2 m.

An acoustic warning is first given:

By the front sensors and the two rear corner sensors at approx. 24 in/60 cm.

By the rear middle sensors at approx. 5 ft/1.50 m.

To ensure full functionality:

Do not cover sensors, e.g., with stickers, bicycle racks.

Keep the sensors clean and free of ice.

When using high-pressure washers, do not spray the sensors for long periods and maintain a distance of at least 12 in/30 cm.

Hints

BMW 428i Convertible (2016) - Hints - 1

Personal responsibility

Even an active system does not relieve the driver from personal responsibility while driving.

Technically the system has its limits, it cannot independently react to all traffic situations.

Monitor your driving, be on the alert, observe the vehicle surroundings and other traffic and react when needed - risk of accident.

BMW 428i Convertible (2016) - Hints - 2

Avoid driving fast with PDC

Avoid approaching an object too fast.

Avoid driving off fast while PDC is not yet active.

For technical reasons, the system may otherwise be too late in issuing a warning.

Signal tones

When approaching an object, an intermittent sound indicates the position of the object. E. g. if an object is detected to the left rear of the vehicle, a signal tone sounds from the left rear speaker.

The shorter the distance to the object, the shorter the intervals.

If the distance to a detected object is less than approx. 10 in/25 cm, a continuous tone is sounded.

With front PDC: if objects are located both in front of and behind the vehicle, an alternating continuous signal is sounded.

The signal tone is switched off, when selector lever position P is engaged on vehicles with Steptronic transmission.

Volume

The volume of the PDC signal tone can be adjusted similar to the sound and volume settings of the radio.

Settings are stored for the profile currently in use.

Visual warning

The approach of the vehicle to an object can be shown on the Control Display. Objects that are farther away are already displayed on the Control Display before a signal sounds.

A display appears as soon as Park Distance Control (PDC) is activated.

The range of the sensors is represented in the colors green, yellow and red.

When the image of the rearview camera is displayed, the reel can be made to PDC:

Things to remember when driving

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features that are not necessarily available in your car, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. The respectively applicable country provisions must be observed when using the respective features and systems.

Breaking-in period

General information

Moving parts need time to adjust to one another (break-in time).

The following instructions will help accomplish a long vehicle life and good efficiency.

During break-in, do not use the Launch Control, refer to page 74.

Engine, transmission, and axle drive

Up to 1,200 miles/2,000 km

Do not exceed the maximum engine and road speed:

▶ For gasoline engine 4,500 rpm and 100 mph/160 km/h.

Avoid full load or kickdown under all circumstances.

From 1,200 miles/2,000 km

The engine and vehicle speed can gradually be increased.

Tires

Tire traction is not optimal due to manufacturing circumstances when tires are brand-new;

they achieve their full traction potential after a break-in time.

Drive conservatively for the first 200 miles/300 km.

Brake system

Brakes require an initial break-in period of approx. 300 miles/500 km to achieve optimal performance between brake discs and brake pads. Drive moderately during this break-in period.

Following part replacement

The same break-in procedures should be observed if any of the components above-mentioned have to be renewed in the course of the vehicle's operating life.

General driving notes

Closing the trunk lid

Drive with the trunk lid closed

Only drive with the tailgate closed; otherwise, in the event of an accident or braking and evasive maneuvers, passengers and other traffic may be injured, and the vehicle may be damaged. In addition, exhaust fumes may enter the vehicle interior.

If driving with the tailgate open cannot be avoided:

▶ If the hardtop is closed, close all windows.
▶ Greatly increase the air flow from the vents.
▶ Drive moderately.

Hot exhaust system

Otherwise, the vehicle's electronics and mobile communication devices can interfere with each other. In addition, there is no assurance that the radiation generated during transmission will be conducted away from the vehicle interior.

Hydroplaning

BMW 428i Convertible (2016) - Hydroplaning - 1

Hydroplaning

When driving on wet or slushy roads, reduce your speed to prevent hydroplaning.

On wet or slushy roads, a wedge of water can form between the tires and road surface.

This phenomenon is referred to as hydroplaning. It is characterized by a partial or complete loss of contact between the tires and the road surface, ultimately undermining your ability to steer and brake the vehicle.

Driving through water

BMW 428i Convertible (2016) - Driving through water - 1

Observe water level and speed

Do not exceed the maximum water level and maximum speed; otherwise, the vehicle's engine, the electrical systems and the transmission may be damaged.

Drive though calm water only and only if it is not deeper than 9.8 inches/25 cm and at this height, no faster than walking speed, up to 3 mph/5 km/h.

Braking safely

Your vehicle is equipped with ABS as a standard feature.

Applying the brakes fully is the most effective way of braking in situations needed.

Steering is still responsive. You can still avoid any obstacles with a minimum of steering effort.

Pulsation of the brake pedal and sounds from the hydraulic circuits indicate that ABS is in its active mode.

In certain braking situations, the perforated brake discs can cause functional problems.

However, this has no effect on the performance and operational reliability of the brake.

Objects within the range of movement of the pedals

BMW 428i Convertible (2016) - Objects within the range of movement of the pedals - 1

No objects in the area around the pedals

Keep floor mats, carpets, and any other objects out of the pedal area; otherwise, the function of the pedals could be impeded while driving and create the risk of an accident.

Do not place additional floor mats over existing mats or other objects.

Only use floor mats that have been approved for the vehicle and can be properly attached to floor.

Ensure that the floor mats are securely fastened again after they were removed for cleaning, e.g.

Driving in wet conditions

When roads are wet, salted, or in heavy rain, press brake pedal ever so gently every few miles.

Ensure that this action does not endanger other traffic.

The heat generated in this process helps dry the brake discs and pads.

In this way braking efficiency will be available when you need it.

Hills

BMW 428i Convertible (2016) - Hills - 1

Avoid stressing the brakes

Avoid placing excessive stress on the brake system. Light but consistent brake pressure can lead to high temperatures, brakes wearing out and possibly even brake failure.

BMW 428i Convertible (2016) - Hills - 2

Do not drive in neutral

Do not drive in neutral or with the engine stopped, as doing so disables engine braking. In addition, steering and brake assist are unavailable with the engine stopped.

Drive long or steep downhill gradients in the gear that requires least braking efforts. Otherwise the brakes may overheat and reduce brake efficiency.

You can increase the engine's braking effect by shifting down, going all the way to first gear, if needed.

Brake disc corrosion

Brake disc corrosion and contamination of the brake pads are favored by:

▶ Low mileage.
▶ Extended periods when the vehicle is not used at all.
▶ Infrequent use of the brakes.

Corrosion will built up when the maximum pressure applied to the brake pads during braking is not reached - thus discs don't get cleaned.

Corrosion buildup on the brake discs will cause a pulsating effect on the brakes in their response - generally that cannot be corrected.

Condensation under the parked vehicle

When using the automatic climate control, condensation water develops collecting underneath the vehicle.

These traces of water under the vehicle are normal.

Loading

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features that are not necessarily available in your car, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. The respectively applicable country provisions must be observed when using the respective features and systems.

Hints

BMW 428i Convertible (2016) - Hints - 1

Overloading the vehicle

To avoid exceeding the approved capacity of the tires, never overload the vehicle. Overloading can lead to overheating and increases the rate at which damage develops inside the tires. This could result in a sudden loss of tire inflation pressure.

BMW 428i Convertible (2016) - Hints - 2

No fluids in the cargo area

Make sure that fluids do not leak into the cargo area; otherwise, the vehicle may be damaged.

BMW 428i Convertible (2016) - Hints - 3

Heavy and hard objects

Do not stow any heavy and hard objects in the car's interior without securing them; otherwise, they may present a danger to occupants, e.g., during braking and evasive maneuvers.

BMW 428i Convertible (2016) - Hints - 4

Loading with hardtop open

Before opening the hardtop, fold down the cargo area partition and make sure the loading is correct. Otherwise, parts of the hard-top can be damaged.

Determining the load limit

  1. Locate the following statement on your vehicle's placard:

The combined weight of occupants and cargo should never exceed XXX kg or YYY lbs. Otherwise, damage to the vehicle and unstable driving situations may result.

Interior view of a car showing the door, seat, and dashboard (no text or symbols visible)

  1. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
  2. Subtract the combined weight of the driver and passengers from XXX kilograms or YYY pounds.
  3. The resulting figure equals the available amount of cargo and luggage load capacity.

For example, if the YYY amount equals 1,000 lbs and there will be four 150 lbs passengers in your vehicle, the amount of available cargo and luggage load capacity is 400 lbs: 1,000 lbs minus 600 lbs = 400 lbs.

  1. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

Load

+ ≤ Max. Load + ≤ Max. Load + ≤ Max. Load

The maximum load is the sum of the weight of the occupants and the cargo.

The greater the weight of the occupants, the less cargo that can be transported.

Stowing cargo

▶ Cover sharp edges and corners on the cargo.
▶ Heavy cargo: stow as far forward as possible, directly behind and at the bottom of the rear passenger seat backrests.
▶ Very heavy cargo: when the rear seat is not occupied, secure each of the outer safety belts in the opposite buckle.
▶ If necessary, fold down the rear backrests to stow cargo.
▶ Use loading aid, refer to page 160, for easier loading.
▶ Using the trunk, refer to page 48.
Do not stack cargo above the top edge of the backrests.

Securing cargo

Securing cargo

BMW 428i Convertible (2016) - Securing cargo - 1

Securing cargo

Stow and secure the cargo as described; otherwise it may present a danger to the occupants, e.g., during braking and evasive maneuvers.

▶ Smaller and lighter items: secure with retaining straps or draw straps.
▶ Larger and heavy objects: secure with cargo straps.

Attach the cargo straps, retaining straps or draw straps to the lashing eyes in the trunk.

Saving fuel

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features that are not necessarily available in your car, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. The respectively applicable country provisions must be observed when using the respective features and systems.

General information

Your vehicle contains advanced technology for the reduction of fuel consumption and emissions.

Fuel consumption depends on a number of different factors.

Carrying out certain measures, such as a moderate driving style and regular maintenance, can influence fuel consumption and the environmental impact.

Remove unnecessary cargo

Additional weight increases fuel consumption.

Remove attached parts following use

Attached parts on the vehicle impair the aerodynamics and increase the fuel consumption.

Closing the windows

Open windows increase air resistance and therefore lead to greater fuel consumption.

Tires

General information

Tires can affect fuel consumption in various ways, e.g., tire size may influence fuel consumption.

Check the tire inflation pressure regularly

Check and, if needed, correct the tire inflation pressure at least twice a month and before starting on a long trip.

Low tire inflation pressure increases rolling resistance and thus raises fuel consumption and tire wear.

Drive away immediately

Do not wait for the engine to warm-up while the vehicle remains stationary. Start driving right away, but at moderate engine speeds.

This is the quickest way of warming the cold engine up to operating temperature.

Look well ahead when driving

Avoid unnecessary acceleration and braking.

By maintaining a suitable distance to the vehicle driving ahead of you.

Driving smoothly and proactively reduces fuel consumption.

Avoid high engine speeds

As a rule: driving at low engine speeds lowers fuel consumption and reduces wear.

Use 1st gear to get the vehicle moving. Starting with the 2nd gear, accelerate rapidly. When

accelerating, shift up before reaching high engine speeds.

When you reach the desired speed, shift into the highest applicable gear and drive with the engine speed as low as possible and at a constant speed.

If necessary, observe the gear shift indicator of the vehicle, refer to page 83.

Use coasting

When approaching a red light, take your foot off the accelerator and let the vehicle coast to a halt.

For going downhill take your foot off the accelerator and let the vehicle roll.

The flow of fuel is interrupted while coasting.

Switch off the engine during longer stops

Switch off the engine during longer stops, e.g., at traffic lights, railroad crossings or in traffic congestion.

Auto Start/Stop function

The Auto Start/Stop function of your vehicle automatically switches off the engine during a stop.

If the engine is switched off and then restarted rather than leaving the engine running constantly, fuel consumption and emissions are reduced. Savings can begin within a few seconds of switching off the engine.

In addition, fuel consumption is also determined by other factors, such as driving style, road conditions, maintenance or environmental factors.

Switch off any functions that are not currently needed

Functions such as seat heating and the rear window defroster require a lot of energy and reduce the range, especially in city and stop-and-go traffic.

Reel off these functions if they are not needed.

The ECO PRO driving program supports the energy conserving use of comfort features.

These functions are automatically deactivated partially or completely.

Have maintenance carried out

Have vehicles maintained regularly to achieve optimal vehicle efficiency and operating life. The maintenance should be carried out by your service center.

Also note the BMW Maintenance System, refer to page 205.

ECO PRO

The concept

ECO PRO supports a driving style that saves on fuel consumption. For this purpose, the engine control and comfort features, e. g. the climate control output, are adjusted.

Under certain conditions the engine is automatically decoupled from the transmission in the D selector lever position. The vehicle continues traveling with the engine idling to reduce fuel consumption. Selector lever position D remains engaged.

In addition, context-sensitive instructions are displayed to assist with an optimized fuel consumption driving style.

The achieved extended range is displayed in the instrument cluster as bonus range.

Fuel recommendation

Note

BMW 428i Convertible (2016) - Note - 1

General fuel quality

Even fuels that conform to the specifications can be of low quality. This may cause engine problems, for instance poor engine start-up behavior, poor handling and/or poor performance. Switch gas stations or use a brand name fuel with a higher octane rating.

Gasoline

For the best fuel efficiency, the gasoline should be sulfur-free or very low in sulfur content.

Fuels that are marked on the gas pump as containing metal must not be used.

BMW 428i Convertible (2016) - Gasoline - 1

Refuel only with unleaded gasoline without metallic additives.

Do not refuel with any leaded gasoline or gasoline with metallic additives, e. g. manganese or iron, as this can cause permanent damage to the catalytic converter and other components.

Fuels with a maximum ethanol content of 10 %, i. e., E10, may be used for refueling.

Ethanol should satisfy the following quality standards:

US: ASTM 4806-xx

CAN: CGSB-3.511-xx

xx: comply with the current standard in each case.

BMW 428i Convertible (2016) - Gasoline - 2

Do not use a fuel with a higher percentage of ethanol

Do not use a fuel with a higher ethanol percentage than recommended or one with other types of alcohol, e.g. M5 to M100; otherwise this could damage the engine and fuel supply system.

BMW recommends AKI 91.

Minimum fuel grade

BMW recommends AKI 89.

BMW 428i Convertible (2016) - Minimum fuel grade - 1

Minimum fuel grade

Do not use any gasoline below the minimum fuel grade as this may impair engine performance.

If you use gasoline with this minimum AKI Rating, the engine may produce knocking sounds when starting at high outside temperatures. This has no effect on the engine life.

BMW 428i Convertible (2016) - Minimum fuel grade - 2

Fuel quality

The use of poor-quality fuels may result in harmful engine deposits or damage. Additionally, problems relating to drivability, starting and stalling, especially under certain environmental conditions such as high ambient temperature and high altitude, may occur.

If drivability problems are encountered, we recommend switching to a high quality gasoline brand and a higher octane grade — AKI number — for a few tank fills. To avoid harmful en-

gine deposits, it is highly recommended to purchase gasoline from Top Tier retailers.

Failure to comply with these recommendations may result in the need for unscheduled maintenance.

Tire inflation pressure

Safety information

The tire characteristics and tire inflation pressure influence the following:

The service life of the tires.
Road safety.
▶ Driving comfort.

Checking the tire inflation pressure

BMW 428i Convertible (2016) - Checking the tire inflation pressure - 1

Check the tire inflation pressure regularly

Regularly check the tire inflation pres-

sure, and correct it as needed: at least twice a month and before a long trip. If you fail to observe this precaution, you may be driving on tires with incorrect tire pressures, a condition that may not only compromise your vehicle's driving stability, but also lead to tire damage and the risk of an accident.

Tires have a natural, consistent loss of tire inflation pressure.

Tires heat up while driving, and the tire inflation pressure increases along with the tire's temperature. The tire inflation pressure specifications relate to cold tires or tires with the ambient temperature.

Only check the tire inflation pressure when the tires are cold. This means after driving no more than 1.25 miles/2 km or when the vehicle has been parked for at least 2 hours.

The displays of inflation devices may under-read by up to 1.45 psi/0.1 bar.

For Flat Tire Monitor: after correcting the tire inflation pressure, reinitialize the Flat Tire Monitor.

For Tire Pressure Monitor: after correcting the tire inflation pressure, reset the Tire Pressure Monitor.

Tire inflation pressure specifications

The tire inflation pressure table, refer to page 187, contains all tire inflation pressure specifications for the specified tire sizes at the ambient temperature. Tire inflation pressure specifications apply to approved tire sizes and recommended tire brands. This information can be obtained from your service center.

To identify the correct tire inflation pressure, please note the following:

▶ Tire sizes of your vehicle.
▶ Maximum permitted driving speed.

Tire inflation pressures up to 100 mph/160 km/h

For speeds of up to 100 mph/160 km/h and for optimum driving comfort, note the pressure values in the tire inflation pressure table, refer to page 187, and adjust as necessary.

Tires with DOT codes meet the guidelines of the U.S. Department of Transportation.

Tire age

DOT ... 0115: the tire was manufactured in the 1st week of 2015.

Recommendation

Regardless of wear and tear, replace tires at least every 6 years.

Uniform Tire Quality Grading

Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width.

For example: Treadwear 200; Traction AA; Temperature A

DOT Quality Grades

Treadwear

Traction AA A B C

Temperature A B C

All passenger car tires must conform to Federal Safety Requirements in addition to these grades.

Treadwear

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half, 1 g, times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction

The traction grades, from highest to lowest, are AA, A, B, and C.

Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Temperature

The temperature grades are A, the highest, B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades Band A represent higher levels of performance on

the laboratory test wheel than the minimum required by law.

BMW 428i Convertible (2016) - Temperature - 1

Temperature grade for this tire

The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

If necessary, have the vehicle towed.

RSC – Run-flat tires

Run-flat tires, refer to page 194, are labeled with a circular symbol containing the letters RSC marked on the sidewall.

M+S

Winter and all-season tires with better cold weather performance than summer tires.

Tire tread

Summer tires

Do not drive with a tire tread depth of less than 0.12 in/3 mm.

There is an increased danger of hydroplaning if the tire tread depth is less than 0.12 in/3 mm.

Winter tires

Do not drive with a tire tread depth of less than 0.16 in/4 mm.

Below a tread depth of 0.16 in/4 mm, tires are less suitable for winter operation.

Minimum tread depth

3D rendered diagram of a vehicle's suspension system showing two blocks on a grid-patterned surface (no text or symbols)

Wear indicators are distributed around the tire's circumference and have the legally required minimum height of 0.063 in/1.6 mm.

They are marked on the side of the tire with TWI, Tread Wear Indicator.

Tire damage

General information

Inspect your tires often for damage, foreign objects lodged in the tread, and tread wear.

Hints

Driving over rough or damaged road surfaces, as well as debris, curbs and other obstacles can cause serious damage to wheels, tires and suspension parts. This is more likely to occur with low-profile tires, which provide less cushioning between the wheel and the road. Be careful to avoid road hazards and reduce your speed, especially if your vehicle is equipped with low-profile tires.

Indications of tire damage or other vehicle defects:

▶ Unusual vibrations while driving.
▶ Unusual handling such as a strong tendency to pull to the left or right.

Damage can, e. g., be caused by driving over curbs, road damage, or similar things.

In case of tire damage If there are indications

If there are indications of tire damage, reduce your speed immediately and have the rims and tires checked right away; otherwise, there is the increased risk of an accident.

Drive carefully to the nearest service center. If necessary, have the vehicle towed or transported there. Otherwise, tire damage can become life threatening for vehicle occupants and also other traffic.

Repair of tire damage For safety reasons, th

For safety reasons, the manufacturer of your vehicle recommends that you do not have damaged tires repaired; they should be replaced. Otherwise, damage can occur as a result.

Changing wheels and tires

Mounting

Information on mounting tires

Have mounting and balancing performed only by a service center.

If work is not carried out properly, there is a danger of subsequent damage and related safety hazards.

Wheel and tire combination

You can ask the service center about the right wheel/tire combination and wheel rim versions for the vehicle.

Incorrect wheel and tire combinations impair the function of a variety of systems such as ABS or DSC.

To maintain good handling and vehicle response, use only tires with a single tread configuration from a single manufacturer.

Following tire damage, have the original wheel and tire combination remounted on the vehicle as soon as possible.

BMW 428i Convertible (2016) - Wheel and tire combination - 1

Approved wheels and tires

You should only use wheels and tires that have been approved by the vehicle manufacturer for your vehicle type; otherwise, e.g., despite having the same official size ratings, variations can lead to chassis contact and with it, the risk of severe accidents

The manufacturer of your vehicle cannot evaluate non-approved wheels and tires to determine if they are suited for use, and therefore cannot guarantee the operating safety of the vehicle.

Close-up of a car tire with a star marking on the side (no text or symbols visible)

For each tire size, the manufacturer of your vehicle recommends certain tire brands. These can be identified by a star on the tire sidewall. With proper use, these tires meet the highest standards for safety and handling.

New tires

Tire traction is not optimal due to manufacturing circumstances when tires are brand-new; they achieve their full traction potential after a break-in time.

Drive conservatively for the first 200 miles/300 km.

Retreaded tires

The manufacturer of your vehicle does not recommend the use of retreaded tires.

BMW 428i Convertible (2016) - Retreaded tires - 1

Retreaded tires

Possibly substantial variations in the design and age of the tire casing structures can limit service life and have a negative impact on road safety.

Winter tires

Winter tires are recommended for operating on winter roads.

Although so-called all-season M+S tires provide better winter traction than summer tires, they do not provide the same level of performance as winter tires.

Maximum speed of winter tires

If the maximum speed of the vehicle is higher than the permissible speed for the winter tires, then a respective symbol is displayed in your field of vision. You can obtain this sign from the tire specialist or from your service center.

BMW 428i Convertible (2016) - Maximum speed of winter tires - 1

Maximum speed for winter tires

Do not exceed the maximum speed for the respective winter tires; otherwise, tire damage and accidents can occur.

Run-flat tires

If you are already using run-flat tires, for your own safety you should replace them only with the same kind. No spare tire is available in the case of a flat tire. Your service center will be glad to advise you.

Rotating wheels between axles

Different wear patterns can occur on the front and rear axles depending on individual driving conditions. The tires can be rotated between the axles to achieve even wear. Your service center will be glad to advise you. After rotating, check the tire pressure and correct if needed.

Rotating the tires is not permissible on vehicles with different tire sizes or rim sizes on the front and rear axles.

Storage

Store wheels and tires in a cool, dry place with as little exposure to light as possible.

Always protect tires against all contact with oil, grease and fuels.

Do not exceed the maximum tire inflation pressure indicated on the side wall of the tire.

Run-flat tires

Label

Close-up of a car tire with a logo on the rim (no visible text or symbols)

RSC label on the tire sidewall.

The wheels consist of tires that are self-supporting, to a limited degree, and possibly special rims.

The support of the sidewall allows the tire to remain drivable to a restricted degree in the event of a tire inflation pressure loss.

Follow the instructions for continued driving with a flat tire.

Changing run-flat tires

For your own safety, only use run-flat tires. No spare tire is available in the case of a flat tire. Your service center will be glad to advise you.

Mobility System

The concept

With the Mobility System, minor tire damage can be sealed quickly to enable continued travel. To accomplish this, sealant is pumped

into the tires, which seals the damage from the inside.

The compressor can be used to check the tire inflation pressure.

Hints

▶ Follow the instructions on using the Mobility System found on the compressor and sealant container.
▶ Use of the Mobility System may be ineffective if the tire puncture measures approx. 1/8 in/4 mm or more.
▶ Contact the nearest service center if the tire cannot be made drivable.
▶ If possible, do not remove foreign bodies that have penetrated the tire.
▶ Pull the speed limit sticker off the sealant container and apply it to the steering wheel.
The use of a sealant can damage the TPM wheel electronics. In this case, have the electronics checked at the next opportunity and have them replaced if needed.

Vehicle care

Car care products

BMW recommends using care and cleaning products from BMW, since these have been tested and approved.

BMW 428i Convertible (2016) - Car care products - 1

Car care and cleaning products Follow the instructions on the container.

When cleaning the interior, open the doors or windows.

Only use products intended for cleaning vehicles.

Cleansers can contain substances that are dangerous and harmful to your health.

Vehicle paint

Regular care contributes to driving safety and value retention. Environmental influences in areas with elevated air pollution or natural contaminants, such as tree resin or pollen can affect the vehicle's paintwork. Tailor the frequency and extent of your car care to these influences.

Aggressive substances such as spilled fuel, oil, grease or bird droppings, must be removed immediately to prevent the finish from being altered or discolored.

Leather care

Remove dust from the leather often, using a cloth or vacuum cleaner.

Otherwise, particles of dust and road grime chafe in pores and folds, and lead to increased wear and premature degradation of the leather surface.

To guard against discoloration, such as from clothing, provide leather care roughly every two months.

Clean light-colored leather more frequently because soiling on such surfaces is substantially more visible.

Use leather care products; otherwise, dirt and grease will gradually break down the protective layer of the leather surface.

Suitable care products are available from the service center.

Upholstery material care

Vacuum regularly with a vacuum cleaner.

If upholstery is very dirty, e.g., with beverage stains, use a soft sponge or microfiber cloth with a suitable interior cleaner.

Clean the upholstery down to the seams using large sweeping motions. Avoid rubbing the material vigorously.

BMW 428i Convertible (2016) - Upholstery material care - 1

Damage from Velcro® fasteners

Open Velcro® fasteners on pants or

other articles of clothing can damage the seat covers. Ensure that any Velcro® fasteners are closed.

Caring for special components

Light-alloy wheels

When cleaning the vehicle, use only neutral wheel cleaners having a pH value from 5 to 9. Do not use abrasive cleaning agents or steam jets above 140 °F/60 °C. Follow the manufacturer's instructions.

Aggressive, acidic or alkaline cleaning agents can destroy the protective layer of adjacent components, such as the brake disk.

These include:

▶ Imitation leather surfaces.

▶ Roofliner.

▷ Lamp lenses.

▶ Instrument cluster cover.

Ensure that the floor mats are securely fastened again after they were removed for cleaning, e.g.

Floor mats can be removed from the car's interior for cleaning.

If the floor carpets are very dirty, clean with a microfiber cloth and water or a textile cleaner. To prevent matting of the carpet, rub back and forth in the direction of travel only.
