(Rear Collision Warning.)

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:

  • A vehicle approaching from behind is detected at a late stage.
  • A vehicle approaching from the rear lane changes 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.
