2. Brake support This helps the driver brake efficiently in a critical situation. 3. Auto-brake This function brakes the vehicle automatically if a collision cannot be avoided. WARNING The auto-brake function cannot prevent a collision but is instead intended to reduce speed at the moment of impact. For full braking effect, the driver must apply the brakes. WARNING The collision warning system does not work in all driving situations, and traffic, weather and road conditions. Warnings are only provided when the risk of collision is high. The Function section provides information about limitations that the driver must be aware of before use. Never wait for a collision warning. This system is designed to be a supplementary driving aid. It is not, however, intended to replace the driver's attention and judgement. The driver is responsible for maintaining a safe distance and speed, even when the collision warning system is in use. Maintenance of the collision warning system components must only be performed by a trained and qualified Volvo technician.
