What to do if …?Lamps in instrument clusterGeneral information:
If a bulb in the instrument cluster fails to
come on during the bulb self-check when the ignition is turned on, have it checked
and replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction in-
dicator lamp comes on while
driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP are
also switched off (see messages in display).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*, Distron-
ic*, and the automatic transmission may
also be malfunctioning.
Continue driving with added caution.
Wheels may 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 increas-
es the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched off.
When the voltage is above this value again,
the ABS is operational again.
If necessary, have the generator and
battery checked.
