Forward Collision Warning (FCW) can help avoid rear-end impacts or minimise the effects of these type of collisions. A radar installation continuously scans the area in front of a vehicle. If it then approaches too close to another vehicle, then the driver is alerted via sound and light signals. If the risk of a collision increases despite the warnings, the brakes are pre-charged to prepare for efficient braking by the driver. When a collision is imminent and the driver doe not react, the car automatically brakes to reduce the impact of the accident. There are variations in the level of implementation of brake support in different models. (some models will only have FCW).
