Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp comes on
while driving.
The ABS has detected a malfunction
and has switched off. The BAS and
ESP
® are also switched off (see mes-
sages in display).
The brake system is still functioning
normally but without the ABS avail-
able.
If the ABS control unit is malfunction-
ing, other systems such as 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 (
page 368).
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 and the ABS has switched
off.
The battery might not be charged suf-
ficiently.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.

Possible causes:
Alternator malfunctioning
Broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may
be operating with restricted capa-
bility. Considerably greater brake
pedal force is required and the stop-
ping distance is increased.
Stop immediately and check the poly-V-belt.
