2008 Volvo V70 Owner's Manual - Page 158

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. Function Visual warning signal, collision risk Radar sensor Camera Collision warning The radar sensor and the camera work together to detect stationary vehicles and vehicles that are moving in the same direction as your vehicle. If there is a risk of collision, the driver is alerted by a flashing red warning light and an audible warning signal. Collision warning is active at speeds above 5 mph (7 km/h). 169 04 Comfort and driving pleasure Collision Warning with Auto-brake (option) Brake support If the risk of collision continues to increase after the collision warning has been given, brake support is activated. Brake support prepares the brake system to react quickly, and the brakes are applied slightly. This may be experienced as a light tug. If the brakes are applied quickly, full braking effect will be provided, even if pressure on the brake pedal is light. Auto-brake If a collision is imminent and the driver has not applied the brakes, the auto-brake function is activated without the driver pressing the brake pedal. Limited brake force is applied to reduce the vehicle's speed when the collision occurs. WARNING
