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/consequence Suggested solution
- The yellow ABS indicator lamp
comes on while the engine is
running. The ABS has detected a malfunction and has
switched off. The BAS, EBP, ESP
® and
PRE-SAFE ® are also switched off (see messages
in multifunction display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit is malfunctioning, other
systems such as the Parktronic system*, Dis-
tronic*, navigation system*, or the automatic
transmission may also be malfunctioning.
̈ Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
̈ Read and observe messages in the
multifunction display (
୴ page 358).
̈ 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.
When the voltage is above this value
again, the ABS is operational again and
the ABS indicator lamp should go out.
If the ABS indicator lamp does not go out:
̈ Have the generator (alternator) and
battery checked.
