General information

Within system limits, the exit warning system can detect traffic approaching from behind such as vehicles, and provide assistance based on this information when you are exiting the vehicle => fig. 122. The system uses the data from the radar sensors at the rear corners of the vehicle.

Displays and warnings

If a door is opened while the vehicle is stationary, the warning strip (1) on that door and the display (2) on that side of the vehicle will blink if another road user is detected in a critical situation. If another road user that is classified as critical is approaching while a door is already open, the displays on that door will turn on.

The same messages apply for the exit warning system and side assist.


  • Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
  • Always pay attention to traffic and to the area around your vehicle. The exit warning system does not replace the attention of the vehicle occupants. The vehicle occupants are always responsible for opening the doors and exiting the vehicle.
  • The exit warning system does not respond to people and cannot warn you about every type of approaching objects, such as cyclists.

    Always monitor the traffic as well as the vehicle's surroundings with direct eye contact.

  • The display may not appear in time when vehicles are approaching very quickly.
  • The exit warning system does not react to stationary objects or pedestrians.
  • The exit warning system will not provide alerts if your vehicle is pulled too far into the parking space so that it is hidden by adjacent vehicles.


  • The exit warning is switched on or off by the side assist warning.
  • The exit warning system can be available for up to approximately three minutes after unlocking the vehicle and opening the door as well as after switching off the ignition. Then the displays flash briefly and the system switches off.
  • The display brightness for the exit warning system cannot be adjusted.
  • The coverage areas of the sensors > fig. 122 are diagrams and do not represent a true-to- scale image of the sensor ranges.
  • The system complies with United States FCC regulations and ISED regulations.
