Volvo XC90: Driver support / Rear Collision Warning limitations


(Warning of collision from the rear.)

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.


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.


The function uses the vehicle's camera and radar sensor, which has certain general limitations.
