Possible cause/consequence
Suggested solution
-
The yellow Antilock Brake
System (ABS) indicator lamp
comes on while the engine is
running.
The ABS has detected a malfunction and
has switched off. The BAS, ESP
® and
PRE-SAFE
® are also switched off (see mes-
sages in multifunction 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*, DIS-
TRONIC Plus*, navigation system, Park As-
sist* and 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 mul-
tifunction display (
page 557).

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. The ABS has switched off.
The battery may not be charged sufficiently.
When the voltage is above this value again,
the ABS is operational again and the ABS in-
dicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.
