In the event that the maintenance service
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Center, you can have the maintenance service indicator re-
set. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the main-
tenance service indicator in the mainte-
nance-relevant information for your
vehicle. Such information is available from
either your authorized Mercedes-Benz
Center or directly from Mercedes-Benz

iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true

need to subtract these days from the
days shown in the maintenance service
indicator.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator :.
iIf the maintenance service indicator
was inadvertently reset, have an autho-
rized Mercedes-Benz Center correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper service as called for by the
maintenance service indicator will re-
sult in engine damage and/or other ve-
hicle damage not covered by the
Mercedes-Benz Limited Warranty.

ment cluster fails to come on during the

and replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction in-
dicator 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 335).
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.

The yellow engine malfunc-
tion indicator lamp comes
on while driving
There is a malfunction in:
The fuel management system
The ignition system
The emission control system
Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the en-
gine to its limp-home (emergency opera-
tion) mode.
Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics system.
It allows the accurate identification of
system malfunctions through the read-
out of diagnostic trouble codes. It is lo-
cated in the front left area of the
footwell next to the parking brake pedal.
Your fuel tank is empty.
After refuelling, start, turn off, and re-
start the engine three or four times in
succession.
The limp-home mode is canceled. You do
not need to have your vehicle checked.
