Rear Collision Warning1
The Rear Collision Warning2 (RCW) function can help the driver to avoid being hit by a vehicle approaching from behind.
This function is activated automatically each time the engine is started.
Drivers in vehicles behind can be warned about an imminent collision by the function flashing intensively with the direction indicators.
If, at a speed below 30 km/h (20 mph), the function detects that the car is in danger of being hit from behind, the seatbelt tensioners may tension the front seatbelts and activate the Whiplash Protection System safety system.
Immediately before a collision from behind, this function may also activate the foot brake in order to reduce the forward acceleration of the car during the collision. However, the foot brake is only activated if the car is stationary. The foot brake releases immediately if the accelerator pedal is depressed.
