tion, hill start assist, the adaptive brake lights and ESP
®
trailer

WARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP
® is not operational, ESP ® is unable to stabilise the vehicle.
The danger of skidding and having an accident increases.

Visit a qualified specialist workshop.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic trans-
mission, will not be available.
