174 Controls in detailDriving systemsWarning indicator
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator is located
next to the tailgate.Warning indicatorAs your vehicle approaches an object, one
or more segments will come on, depending
on the distance. When the sixth segment
lights, you have reached the minimum dis-
tance.An intermittent acoustic warning will
sound when the first yellow segment
comes on. This signal quickens with each
additional segment lit. When all segments
illuminate, the acoustic warning becomes
a constant signal. The signal is canceled
when the gear selector lever is placed in
position D or P.
Rear Parking Assist malfunction
There is a malfunction in the Rear Parking
Assist system if:


a low warning tone sounds while the
vehicle is reversing
The Rear Parking Assist sensors are
dirty or malfunctioning.
Clean the Rear Parking Assist sys-
tem sensors (
page 247).

Switch on the ignition again.


no segments come on and no warning
sounds
The Rear Parking Assist is malfunction-
ing.
Have the Rear Parking Assist sys-
tem checked by an authorized
Mercedes-Benz Light Truck Center
as soon as possible.
Malfunction may also be caused by inter-
ference from other radio or ultrasonic sig-
nals.

Check the Rear Parking Assist opera-
tion at another location to rule out in-
terference from outside radio or
ultrasonic signals.

Programming or reprogramming the in-
tegrated remote control
Step 1:
Switch on ignition.
Step 2:

If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator light be-
gins to flash after approximately 20
seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and/or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.
iCertain types of garage door openers
are incompatible with the integrated
opener. If you should experience diffi-
culties with programming the transmit-
ter, contact your authorized
Mercedes-Benz Light Truck Center, or
call Mercedes-Benz Customer Assis-
tance Center (in the USA only) at
1-800-FOR-MERCedes, or Customer
Service (in Canada) at
1-800-387-0100.

228 OperationEngine compartment
Closing
Lower hood and let it drop into lock
from a height of approximately 0.7 ft
(20 cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new


the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage,
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic
socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.!Do not push the hood closed manually,
as this could damage it.
iDo not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz will
restrict your warranty entitlement.
More information on this subject is
available at any Mercedes-Benz Light
Truck Center.

242 OperationMaintenance
MaintenanceWe strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Light Truck Center, in ac-
cordance with the Service Booklet at the
times called for by the FSS (Flexible Ser-
vice System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
service is due, one of the following mes-
sages will appear in the multifunction dis-
play while you are driving or when you
switch on the ignition (example service A):SERVICE A IN XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!
The type of service due is indicated in the
speedometer display field:
9Minor service (A)
½Major service (B)Clearing the service indicator
The service indicator is automatically
cleared


after 10 seconds when you switch on
the ignition or when reaching the ser-
vice threshold while driving


after 30 seconds, once the suggested
service term has passed
You can also clear it yourself.

Press the reset button on the instru-
ment cluster (
page 25).
Service term exceeded
If you have exceeded the suggested ser-
vice term, you will see the following mes-
sage in the multifunction display:SERVICE A EXCEEDED BY XX DAYS
SERVICE A EXCEEDED BY XX MILES (KM)An accoustic signal will sound.
The Mercedes-Benz Light Truck Center will
reset the service indicator following a com-
pleted service.
iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

243 Operation
Maintenance
Calling up the service indicator
Switch ignition on.
The standard display of the control sys-
tem appears (
page 115).

Press buttonk orj on the mul-
tifunction steering wheel until the FSS
indicator appears in the multifunction
display.
Resetting the service indicator
In the event that the service on your vehi-
cle is not carried out by an authorized
Mercedes-Benz Light Truck Center, you
can reset the service indicator yourself.
Switch ignition on.
The standard display of the control sys-
tem appears (
page 115).

Press buttonk orj on the mul-
tifunction steering wheel until the FSS
indicator appears in the multifunction
display.

Press the reset button (
page 25) for
about three seconds.
This message appears in the tachome-
ter:
SERVICE INTERVAL?
RESET WITH R BUTTON FOR 3 SEC.

To confirm, press reset button until you
hear a signal.
The service indicator now displays the
reset interval.
iIf the vehicle battery is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the service indicator
with the engine oil level indicator :.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Light
Truck Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-Benz Limited Warranty.

256 Practical hintsWhat to do if …Problem
Possible cause
Suggested solution
?
The yellow “CHECK ENGINE”
malfunction 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 (emergency operation)
mode. Serious damage can occur to the
emission system.

Have the vehicle checked as soon as
possible 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 sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located near the hood lock
release on the upper left of footwell.
The fuel cap is not closed tightly.

Check 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.
