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 may increase in an emergency braking
situation.
If ESP
®
is not operational, ESP
®
is unable to stabilise the vehicle.
There is an increased danger of skidding and risk of an accident.
X
Carefully drive on a suitable stretch of road, making slight steer-
ing movements, at a speed above 20 km/h.
