Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the key in
steering lock to position 2, have it checked and replaced
if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the
“CHECK ENGINE” malfunction indicator
lamp comes on when the engine is running,
it indicates a malfunction of the fuel management
system, emission control system, systems which impact
emissions, or the fuel cap is not closed tight (check the
fuel cap). If the “CHECK ENGINE” lamp is illuminated
continuously and the vehicle is driving normally, you
may still drive the vehicle, however, in all cases, we
recommend that you have the system checked at your
authorized Mercedes-Benz Light Truck Center as soon
as possible.
If the “CHECK ENGINE” lamp comes on continuously
and / or the vehicle is not driving normally (e.g.
malfunction of the fuel management system or running out of fuel), serious damage can occur to the emission
system. Please contact your authorized Mercedes-Benz
Light Truck Center immediately.
The Sequential Multiport Fuel Injection (SFI) control
module monitors emission control components that
either provide input signals to or receive output signals
from the control module. Malfunctions resulting from
interruptions or failure of any of these components are
indicated by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster and are
simultaneously stored in the SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
With some exceptions, the control module switches off
the “CHECK ENGINE” malfunction indicator lamp if the
condition, causing the lamp to come on, no longer exists
during three consecutive cycles. See also page 220 for
fuel cap placement warning.
An on-board diagnostic connector is located in the
passenger compartment near to the parking brake
pedal, allowing the accurate identification of system
malfunctions through the readout of diagnostic trouble
codes.

powertrain, however you should d o the following:
•With damage to front axle, raise front axle. Remove
flexible drive shaft between rear axle and transfer

vehicle with wheel lift or dolly placed under front
wheels.
•With damage to transfer case, remove flexible drive
shafts to the drive axles.
Note:
Always install new self-locking nuts when reinstalling
the flexible drive shaft.Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in steering lock position 1).
Otherwise, the 4-ETS+ may become engaged which may
cause loss of towing control. Switch off the tow-away
alarm (see page 36) as well as the ESP (see page 207).
Note:
To signal turns while being towed with hazard warning
flasher in use, turn key in steering lock to position 2
and activate combination switch for left or right turn
signal in usual manner. Now deactivate the hazard
warning flasher, only the selected turn signal will
operate. Upon canceling the turn signal, the hazard
warning flasher must be activated again.
Wa r n i n g !
With the engine not running, there is no power
assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to
brake and steer the vehicle.
