comes on while driving.
There may be a malfunction in the
fuel management system
ignition system (gasoline engine)
emission control system
systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine

mode.
Have the vehicle checked as soon as possi-
ble 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 malfunc-
tions through the readout of diagnostic trou-
ble codes. It is located in the front left area
of the footwell next to the parking brake.
