attention to road and traffic conditions. Do not continue driving

under any circumstances.

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.

is not operational, ESP

is unable to stabilise the vehicle.

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.
