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 affected. The braking
distance may increase in an emergency braking situation.
If ESP
®
is not operational, ESP
®
is unable to stabilise the vehicle.
There is an increased risk of skidding and/or accident.

If the ABS control unit is faulty, there is also a possibility that other systems, such
as the navigation system or the automatic transmission, will be unavailable.
