Limitations of Rear Collision Warning*

In certain cases the Rear Collision Warning (RCW)1 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.


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.


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