WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
display messages which may be shown in the
instrument cluster (
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery roads,
even if you only brake gently.
Braking
If ABS intervenes: continue to depress the
X
brake pedal vigorously until the braking
situation is over.
To make a full brake application:

indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving.
