378 Practical hintsWhat to do if …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 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, ESP
®, EBP and
PRE-SAFE
® are also switched off (see
messages in the multifunction display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit is malfunctioning, oth-
er systems such as Distronic*, or the auto-
matic 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 394).

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 might not be charged sufficiently.
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
the battery checked.

See Operator’s Man.
The ABS, ESP
® as well as PRE-SAFE
®
were deactivated because of insuffi-
cient power supply. The charging
voltage has fallen below 10 volts.
BAS is also switched off.
The brake system still functions nor-
mally but without the ABS, BAS,
ESP
® and PRE-SAFE
® available.
When the voltage is above this value again, the
ABS, ESP
® and PRE-SAFE
® are operational
again and the message should disappear.
If the message does not disappear:

Have the generator (alternator) and the bat-
tery checked.

#
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 in-
creased.

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 in-
operative water pump which may re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:

Drive immediately to the nearest au-
thorized Mercedes-Benz Center. Ad-
just driving to be consistent with
reduced braking responsiveness.
There is a malfunction in the electronic
system.

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.

Battery/Alternator
Stop vehicle
The battery is malfunctioning.
The brake system requires electrical en-
ergy and therefore has only limited oper-
ation. Considerably greater brake pedal
force is required and the stopping dis-
tance is increased.

Stop the vehicle in a safe location as
soon as it is safe to do so. Adjust driv-
ing to be consistent with reduced
braking responsiveness.

Notify an authorized Mercedes-Benz
Center.
Low voltage
Start engine
The battery has insufficient voltage.

Start the engine (

not locked
The rear seat backrest is not engaged.

Adjust the rear seat backrest until it is
fully engaged in position.
Left rear backrest

The rear seat backrest is not engaged.

Adjust the rear seat backrest until it is
fully engaged in position.

Brakepad wear
The brake pads have reached their wear
limit.

Have the brake pads replaced as soon
as possible.
!
Brake pad thickness must be visually in-
spected by a qualified technician at the intervals
specified in the Maintenance Booklet.
