Driving and Driving Safety Systems

Driving systems and your responsibility
Your vehicle is equipped with driving systems that assist you in driving, parking and manoeuvring 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 ( Car sensors )

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.Driving And Driving Safety Systems1

  1. Multifunction camera
  2. Cameras in the outside mirrors
  3. Front radar
  4. Front Camera
  5. Corner radars
  6. Ultrasonic sensors
  7. Rearview 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 414). 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 a bumper or the radiator grill is damaged 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.

2023 S-CLASS Functions of ABS User Manual

ABS operation

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

  • During braking, for instance, at maximum full-stop braking or if there is insufficient tire traction, the wheels are prevented from locking.
  • Vehicle steerability while braking is ensured.
    If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions and can serve as a reminder to take extra care while driving.

System limits

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

Function of BAS

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.

Mercedes-AMG vehicles

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
  • Display messages

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

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.
  • The vehicle is stabilized by means of individual brake application on one side.

Activating/deactivating ESP® (Electronic Stability Program)

Multimedia system:
Home>Setting >y

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.

Mercedes-AMG vehicles

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

  • Select ESP.
  • Select On or Off.

ESP® is deactivated if the å ESP® OFF warning lamp lights up continuously in the driver’s display.
Observe any information on warning lamps and display messages which may be shown in the driver’s display.
