come on during the bulb self-check when the ignition is turned on, have it checked
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 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*, Distron-
ic*, and the automatic transmission may
also be malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
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.
When the voltage is above this value again,
the ABS is operational again.
If necessary, have the generator and
battery checked.

?(USA only)±(Canada only)
The yellow malfunction
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.
The fuel cap is not closed tightly.
Close the fuel cap.
Your gas tank is empty.
After refuelling, start the engine three or
four times in succession.
The limp-home mode is canceled. You do
not need to have your vehicle checked.
