Audio and symbol for collision warning.
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.
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.
Symbol for collision warning on the windscreen.
In cars equipped with a head up display*, the warning is shown on the windscreen by a flashing symbol.
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.
