Volvo XC90: Driver support / Rear Collision Warning

(Option/accessory.)

(Warning of collision from the rear.)

The Rear Collision Warning1 (RCW) function can help the driver avoid rear-end collisions from vehicles approaching from behind.

The function can alert drivers of following vehicles of the risk of a collision by rapidly flashing the turn signals.

If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in danger of being hit from behind, the seat belt tensioners may tension the front seat belts. The Whiplash Protection System will also be activated in a collision.

Immediately before a collision from behind, the function may also activate the brakes in order to reduce the forward acceleration of the vehicle during the collision. However, the brakes will only be applied if your vehicle is stationary. The brakes will be immediately released if the accelerator pedal is depressed.

The function is automatically activated each time the engine is started.
