Warning from driver support in the event of a collision risk
The driver support systems Pilot Assist, and Adaptive Cruise Control (ACC)*1 can warn the driver if the distance to the vehicle ahead suddenly becomes too short.
Audio-visual warning signal in the event of a collision risk
Distance measurement with the camera and radar unit
The driver support uses approx. 40% of the foot brake's capacity. If the car needs to be braked more heavily than the driver support is capable of and the driver does not brake, the warning lamp and acoustic warning are activated to alert the driver that immediate intervention is required.
Warning
The driver support systems only warn of vehicles which their radar unit has detected – hence a warning may not be given, or it may be given with a certain delay. Never wait for a warning. Apply the brakes when the situation requires.
In cars equipped with a head up display*, the warning is shown on the windscreen by a flashing symbol.
Note
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the windscreen difficult to recognise.
