Limitations of Rear Collision Warning*1

In certain cases the Rear Collision Warning (RCW) may have difficulty helping the driver in the event of a collision risk.
This can, for example, be if:
  • the vehicle approaching from behind is detected too late
  • the vehicle approaching from behind changes lane at the last moment
  • a trailer, bicycle rack or similar is connected to the car's electrical system - the function is then deactivated automatically.

 Note

In certain markets, RCW does not give a warning with the direction indicators due to local traffic regulations - in such cases, this part of the function is deactivated.

 Note

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

The seat belt pre-tensioning and braking functions are, however, still active.

 Note

This function uses the car's camera and radar units, which have certain general limitations.
  1. * Option/accessory.
  2. 1 Rear collision warning.
