Other driving systems and driving safety systems may also malfunction.
G WARNING
The brake system continues to function normally, but without the functions listed
above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance in an emergency braking situation can increase.

is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident. X
Observe the additional display messages in the multifunction display. X
Drive on carefully. X
Visit aq ualified specialist workshop immediately.
If the ABS control unit is faulty, there is also ap ossibility that other systems, such
as the navigation system or the automatic transmission, will not be available.204
