Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on ignition 
(
page 37), have the respective bulb 
checked and replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow ABS indicator lamp comes on 
when the engine is running.The ABS has detected a malfunction 
and has switched off. The BAS and 
ESP
® are also switched off (see mes-
sages in the multifunction display).
The brake system is still functioning 
normally but without the systems 
specified above.
If the ABS control unit is malfunction-
ing, other systems such as the naviga-
tion system* or the automatic 
transmission* may also be malfunc-
tioning.
Continue driving with added caution. 
Wheels may lock during hard braking, 
reducing steering capability.
Read and observe messages in the 
multifunction display (
page 356).
Have the system checked at an 
authorized 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 might not be charged suf-
ficiently.When the voltage is above this value 
again, the ABS is operational again an the 
ABS indicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and 
battery checked.
