RCW is activated automatically each time the engine is started.
RCW can warn the driver of a vehicle approaching yours from behind by rapidly flashing your turn signals.
RCW is only activated when a vehicle is rapidly approaching your vehicle from behind.
At speeds below 20 mph (30 km/h), if RCW determines that your vehicle is at risk of a rear-end collision, the front seat belt pretensioners and the Whiplash Protection System are activated.
Just prior to the collision, the brakes are also applied to help reduce your vehicle's forward movement if and when the collision occurs. However, this can only happen if your vehicle is stationary.
The brakes will be released immediately if the accelerator pedal is pressed.
Note
- Due to local traffic regulations in certain markets, Rear Collision Warning (RCW) will not activate the rear turn signals. That part of the function will be deactivated.
- The use of the rear turn signals will also be deactivated if the City Safety warning level is set at Later. See also the section "Setting a warning level (distance)" in the article "City Safety settings."
- If RCW detects a vehicle approaching from behind, the seat belt pretensioners and Whiplash Protection System will be activated.
Limitations
In some circumstances, it may be difficult for RCW to help the driver if there is a risk of a collision, such as:
- If the vehicle approaching from the rear is detected at a late stage
- If the vehicle approaching from the rear changes lanes at a late stage
- If the vehicle approaching from the rear is moving at a speed above approx. 50 mph (80 km/h)
