Rear Collision Warning*1 limitations

In some situations, it may be difficult for Rear Collision Warning (RCW) to warn the driver of a collision risk.
This may be the case if:
  • the vehicle approaching from the rear is detected at a late stage
  • the vehicle approaching from the rear changes lanes at a late stage
  • a trailer, bicycle holder or similar is connected to the vehicle's electrical system - the function will then be automatically deactivated.

 Note

In certain markets RCW does not warn with the direction indicators due to local traffic regulations – in such cases, that part of the function is deactivated.

 Note

The warning with direction indicators for Rear Collision Warning* is deactivated if the collision warning distance in the City Safety function is set to the lowest level "Late".

The seat belt tensioning and braking functions remain active.

 Note

The function uses the vehicle's camera and radar sensor, which has certain general limitations.
  1. * Option/accessory.
  2. 1 Warning of collision from the rear.
