What to do if …
Lamps in instrument cluster General information:
If any of the following lamps in the instru-
ment cluster fails to come on during the bulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.
Problem Possible cause Suggested solution
-
The yellow ABS indicator 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 SBC brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning, oth-
er systems such as the Parktronic system*,
Distronic*, or the automatic transmission
may also be malfunctioning.
왘
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
왘
Read and observe messages in the
display (
컄
page 345).
왘
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.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be sufficiently charged.
왘
Switch off electrical consumers that
are currently not needed, e.g. seat
heating.
왘
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.
