The Driver Alert System consists of different functions which can either be switched on at the same time or individually:
A switched-on function is set in standby mode and is not activated automatically until speed exceeds 65 km/h.
The function is deactivated again when speed decreases to below 60 km/h.
The functions use a camera which is dependent on the lane having side markings painted on each side.
Driver Alert System does not work in all situations but is designed merely as a supplementary aid.
The driver always bears ultimate responsibility for ensuring that the vehicle is driven safely.
