Problem Possible cause/consequence Suggested solution
±
The yellow engine malfunc-
tion indicator lamp comes
on while driving. There is a malfunction in:
ț The fuel management system
ț The ignition system
ț The emission control system
ț 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 at 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.

In some states you may be required by law
to have the vehicle serviced as soon as the
engine malfunction indicator lamp comes on.
Check local requirements.
