Driving and Driving Safety Systems
Driving Systems and Your Responsibility
Your vehicle is equipped with driving systems that assist you in driving, parking and maneuvering the vehicle. The driving systems are only aids. They are not a substitute for you paying attention to your surroundings and do not relieve you of your responsibility pertaining to road traffic law. The driver is always responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Pay attention to the traffic conditions at all times and intervene when necessary. Be aware of the limitations regarding the safe use of these systems.
Driving systems can neither reduce the risk of an accident if you fail to adapt your driving style nor override the laws of physics. They cannot always take into account road, weather or traffic conditions.
- Some driving systems can regulate or limit the speed to a previously set value. Draw attention to the stored speed when changing drivers.
Information on Vehicle Sensors and Cameras
Some driving and driving safety systems use cameras as well as radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle.
- Multifunction camera
- Cameras in the outside mirrors 3 Front radar
- Front camera
- Corner radars
- Ultrasonic sensors
- Rear view camera
Risk of accident due to restricted detection performance of vehicle sensors and cameras
If the area around vehicle sensors or cameras is covered, damaged or dirty, certain driving and safety systems cannot function correctly. There is a risk of an accident.
- Keep the area around vehicle sensors or cameras clear of any obstructions and clean.
- Have damage to the bumper, radiator grille or stone chipping in the area of the front and rear windows repaired at a qualified specialist workshop.
Particularly, keep the areas around the sensors and cameras free of dirt, ice or slush (/ page 290). The sensors and cameras must not be covered and the detection ranges around them must be kept free. Do not attach additional license plate brackets, advertisements, stickers, foils or foils to protect against stone chippings in the detection range of the sensors and cameras. Make sure that there are no overhanging loads protruding into the detection range.
If there is damage to a bumper or the radiator grill, or after an impact, have the function of the sensors checked at a qualified specialist workshop. Have damage or stone chipping in the area of the cameras on the front and rear windows repaired at a qualified specialist workshop.
- The rearview camera can extend and retract automatically for the purpose of calibration, even though there is no camera image in the display.

Functions of ABS
- The Anti-lock Brake System (ABS) regulates the brake pressure in critical driving situations:
- During braking, for instance, at maximum full stop braking or if there is insufficient tire traction, the wheels are prevented from locking.
- R Vehicle steerability while braking is ensured.
- If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions and can serve as a reminder to take extra care while driving.
- ABS is active from speeds of approx. 3 mph (5 km/h).
R ABS may be impaired or may not function if a malfunction has occurred and the yellow!ABS warning lamp lights up continuously after the vehicle is started.
Function of BAS
Risk of an accident caused by a malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance in an emergency braking situation is increased.
- Depress the brake pedal with full force in emergency braking situations. ABS prevents the wheels from locking.
The Brake Assist System (BAS) supports your emergency braking situation with additional brake force.
If you depress the brake pedal quickly, BAS is activated:
- BAS automatically boosts the brake pressure.
- BAS can shorten the braking distance.
- ABS prevents the wheels from locking.
The brakes will function as usual once you release the brake pedal. BAS is deactivated.
Function of ESP®
Risk of skidding if ESP® is deactivated
If you deactivate ESP®, ESP® cannot carry out vehicle stabilization.
- ESP® should only be deactivated in the following situations.
- Observe the notes in the Supplement.
You could otherwise fail to recognize dangers.
The Electronic Stability Program (ESP®) can monitor and improve driving stability and traction in the following situations within physical limits:
- When pulling away on wet or slippery roads.
- When braking.
If the vehicle deviates from the direction desired by the driver, ESP® can stabilize the vehicle by intervening in the following ways:
- One or more wheels are braked.
- The engine output is adapted according to the situation.
When ESP® is deactivated, the å warning lamp lights up continuously:
- Driving stability will no longer be improved.
- The drive wheels could spin.
- ETS/4ETS traction control is still active.
- When ESP® is deactivated, you are still assisted by ESP® when braking.
When the ÷ warning lamp flashes, one or several wheels has reached its grip limit:
- Adapt your driving style to suit the current road and weather conditions.
- Do not deactivate ESP®.
- Only depress the accelerator pedal as far as is necessary when pulling away.
Deactivate ESP® in the following situations to improve traction:
- When using snow chains.
- In deep snow.
- On sand or gravel.
- Spinning the wheels results in a cutting action, which enhances traction.
If the ÷ ESP® warning lamp lights up continuously, ESP® is not available due to a malfunction. Observe the following information:
- Indicator and warning lamps (/ page 412)
- Display messages (/ page 358)
ETS/4ETS (Electronic Traction System)
ETS/4ETS traction control is part of ESP® and makes it possible to pull away and accelerate on a slippery road.
ETS/4ETS can improve the vehicle’s traction by intervening in the following ways:
- The drive wheels are braked individually if they spin.
- More drive torque is transferred to the wheel or wheels with traction.
Influence of drive programs on ESP®
The drive programs enable ESP® to adapt to different weather and road conditions as well as the driver’s preferred driving style. Depending on the selected drive program, the appropriate ESP® mode will be activated. You can select the drive programs using the DYNAMIC SELECT switch (/ page 155).
The function of ESP® Crosswind Assist
ESP® Crosswind Assist detects sudden gusts of side wind and helps the driver to keep the vehicle in the lane:
- ESP® Crosswind Assist is active at vehicle speeds between approx. 50 mph (80 km/h) and 125 mph (200 km/h) when driving straight ahead or cornering slightly.
- R The vehicle is stabilized by means of individual brake application on one side.
Activating/deactivating ESP® (Electronic Stability Program)
Home> Settings > Quick Access
ESP® can only be activated/deactivated using quick access when at least one other function is available in quick access. ESP® can otherwise be found in the Assistance menu.
- Observe the notes in the Supplement.
You could otherwise fail to recognize dangers.
- Select ESP.
- Select On or å Off.
ESP® is deactivated if the å ESP® OFF warning lamp lights up continuously in the instrument cluster.
Observe the information on warning lamps and display messages which may be shown in the instrument cluster.
Function of EBD
Electronic Brakeforce Distribution (EBD) is characterized by the following:
- Monitoring and regulating the brake pressure on the rear wheels.
- Improved driving stability when braking, especially on bends.
The function of STEER CONTROL
STEER CONTROL assists you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization.
This steering recommendation is given in the following situations:
- both right wheels or both left wheels are on a wet or slippery road surface when you brake the vehicle starts to skid
STEER CONTROL may be impaired or may not function in the following situations:
- ESP® is deactivated.
- ESP® is malfunctioning.
- The steering is malfunctioning.
If ESP® is malfunctioning, you will be assisted further by the electric power steering.
The HOLD function holds the vehicle at a standstill without requiring you to depress the brake pedal, e.g. while waiting in traffic.
The HOLD function is only an aid. The responsibility for the vehicle safely standing still remains with the driver.
The HOLD function is only intended to provide assistance when driving and is not a sufficient means of safeguarding the vehicle against rolling away when stationary.
- The incline must not be greater than 30%.
Activating/deactivating the HOLD function
Risk of an accident due to the HOLD function being active when you leave the vehicle
If the vehicle is only braked with the HOLD function it could, in the following situations, roll away:
- If there is a malfunction in the system or in the power supply.
- If the HOLD function is deactivated by depressing the accelerator pedal or brake pedal, e.g. by a vehicle occupant.
- Always secure the vehicle against rolling away before you leave it.
- The vehicle is stationary.
- The driver’s door is closed or the seat belt on the driver’s side is fastened.
- The vehicle has been started or has been automatically switched off by the ECO start/stop function.
- The electric parking brake is released.
- Active Distance Assist DISTRONIC is deactivated.
- The transmission is in position h, k or i.
Activating the HOLD function
- Depress the brake pedal, and after a short time quickly depress further until the ë display appears in the Instrument Display.
- Release the brake pedal.
Deactivating the HOLD function
- Depress the accelerator pedal to pull away.
- Depress the brake pedal until the ë display disappears from the Instrument Display.
The HOLD function is deactivated in the following situations:
- Active Distance Assist DISTRONIC is activated.
- The transmission is shifted to position j. R The vehicle is secured with the electric parking brake.
In the following situations, the vehicle is held by transmission position j and/or by the electric parking brake:
- The seat belt is unfastened and the driver’s door is opened.
- The vehicle is switched off.
- There is a system malfunction.
- The power supply is insufficient.
The function of Hill Start Assist
Hill Start Assist holds the vehicle for a short time when you pull away on a hill under the following conditions:
- The transmission is in position h or k.
- The electric parking brake is released.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to roll away.
Risk of accident and injury due to the vehicle rolling away
After a short time, Hill Start Assist no longer holds the vehicle.
- Swiftly move your foot from the brake pedal to the accelerator pedal. Do not leave the vehicle when it is being held by Hill Start Assist.
The function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monotonous journeys, e.g. on highways and trunk roads. If ATTENTION ASSIST detects indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot always detect fatigue or lapses in concentration in time. The system is not a substitute for a well-res-ted and attentive driver. On long journeys, take regular breaks in good time that allow for adequate recuperation.
You can choose between two settings:
- Standard: normal system sensitivity.
- Sensitive: higher system sensitivity. The driver is warned earlier and the attention level detected by the ATTENTION ASSIST has adapted accordingly.
If drowsiness or increasing lapses in concentration are detected, the ATTENTION ASSIST: Take a Break! warning appears in the Instrument Display. You can acknowledge the message and take a break where necessary. If you do not take a break and ATTENTION ASSIST continues to detect increasing lapses in concentration, you will be warned again after a minimum of 15 minutes.
You can have the following status information for ATTENTION ASSIST displayed in the assistance menu of the on-board computer:
- The length of the journey since the last break.
- The attention level determined by ATTENTION ASSIST:
- The fuller the circle, the higher the attention level determined
- As your attention wanes, the circle in the center of the display becomes smaller
If the ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warning, the System Suspended message appears.
If a warning is given in the Instrument Display, the multimedia system offers to search for a rest area. You can select a rest area and start navigation to this rest area. This function can be activated and deactivated in the multimedia system.
If ATTENTION ASSIST is deactivated, the Û symbol appears in the assistance graphic in the Instrument Display. After the vehicle is started, ATTENTION ASSIST is automatically activated. The last selected sensitivity level remains stored.
ATTENTION ASSIST is active in the 37 mph (60 km/h) to 124 mph (200 km/h) speed range.
Particularly in the following situations, ATTENTION ASSIST only functions in a restricted manner and warnings may be delayed or not occur:
- If you have been driving for less than approximately 30 minutes.
- If the road condition is poor (uneven road sur- face or potholes).
- If there is a strong side wind.
- If you adopt a sporty driving style (high cornering speeds or high rates of acceleration).
- If Active Steering Assist is activated and active(/ page 188).
- If the time has been set incorrectly.
- If you change lanes and vary your speed frequently in active driving situations.
The ATTENTION ASSIST drowsiness or alertness assessment is reset and restarted when continuing the journey in the following situations:
- If you switch off the vehicle.
- R If you unfasten your seat belt and open the driver’s door (e.g. to change drivers or take a break).
