The yellow engine mal-
function indicator lamp
comes on while driving.
There is a malfunction of:
The fuel management system
The ignition system
The emission control system
Systems which impact emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home mode. Serious damage can
occur to the emission system.
Have the vehicle checked as soon as possi-
ble by an authorized Mercedes-Benz Light
Truck 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 near the hood lock
release on the upper left of footwell.
A loss of pressure has been detected in the
fuel system. The fuel cap may not be closed
properly or the fuel system may be leaky.

If it is not closed properly:
Close the fuel cap.
If it is closed properly:
Have the fuel system checked by an autho-
rized Mercedes-Benz Light Truck Center.
Your fuel tank is empty.
After refueling start, turn off and restart the
engine three or four times in succession.
