Practical hints
What to do if ...?
Problem
- The yellow ABS malfunction indi-
cator lamp and warning comes
on while driving.
196
Possible cause
The ABS has detected a malfunction and has
switched off. The BAS and ESP are also
switched off. Both indicator lamps come on
with the engine running.
The brake system is still functioning normally
but without the ABS available.
The charging voltage has fallen below
10 volts and the ABS has switched off.
Suggested solution
Continue driving with added caution.
Wheels will lock during hard braking
reducing steering capability.
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
When the voltage is above this value
again, the ABS is operational again.
If necessary, have the alternator and
battery checked.
