Possible cause/consequence
Suggested solution
-
The yellow Antilock Brake
System (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 multi-
function 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*,
Distronic*, 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 337).

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 and the ABS has switched off.
The battery may not be charged sufficiently.

Switch off electrical consumers that are
currently not needed, e.g. seat heat-
ing*.

If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value again,
the ABS is operational again.

BATTERY CHARGE
VISIT WORKSHOP
The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be oper-
ating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is
longer.

Stop immediately in a safe location or as
soon as it is safe to do so and check the
poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise the
engine will overheat due to an inoperative
water pump which may result in damage
to the engine. Notify an authorized
Mercedes-Benz Center.
If it is intact:

Drive immediately to the nearest autho-
rized Mercedes-Benz Center. Adjust driv-
ing to be consistent with reduced braking
responsiveness.
