The cigarette lighter* (
page 300) or the
power outlet in the front center console
(
page 302) is not designed for use with the
electric air pump. Use the power outlet in the
rear center console or in the cargo compartment
(page 303) for electric air pump operation.
Warning!
G
Air hose4 and union nut5 can become
hot during inflation. Exercise proper caution
to avoid burning yourself when using the
equipment.!
Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again
after it has cooled off.
!
Please compare the recommended tire
inflation pressure for your vehicle with the tire
inflation pressure on the yellow label located on
the spare wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the tire to
the recommended tire inflation pressure given
on the yellow label on the spare wheel rim.
506 Practical hintsBleeding the fuel system (diesel engine only)Driving the vehicle until the fuel tank is
empty is not recommended. Otherwise, air
may be sucked into the fuel system. If this
happens, the? malfunction indicator
lamp (USA only) or the± malfunction
indicator lamp (Canada only) comes on
and the engine may not start immediately
after refueling the vehicle.
After refueling:
Make sure the automatic transmission
is set toP.
The gear position indicator in the multi-
function display should be on
P.
Do not depress the accelerator.

Return the SmartKey in the starter
switch to position 0 (
page 40).
Turn the SmartKey in the starter switch
to position3 (
page 40) and hold it
there for a maximum of 40 seconds or
until the engine runs surge-free.
If the engine does not start:
Wait for approximately 2 minutes.
Turn the SmartKey in the starter switch
to position3 (
page 40) and hold it
there for a maximum of 40 seconds or
until the engine runs surge-free.
If the engine still does not start, do not
make any further attempts to start the
engine. Contact an authorized
Mercedes-Benz Light truck Center or call

Step 1 (Disconnecting)
Set the automatic transmission to
positionP (
page 187).
Firmly depress the parking brake
(page 65).
Turn off the engine (
page 66).
Leave the ignition switched on

could be severely damaged.
Have the battery checked regularly by an
authorized Mercedes-Benz Light Truck Center.
Contact your authorized Mercedes-Benz Light
Truck Center for further information.
Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
Warning!
G
Disconnecting, removing, reinstalling and
reconnecting the battery is a complicated
and technically demanding procedure that
also requires safety precautions to avoid the
risk of injury. We strongly recommend that it
be performed by a qualified technician or an
authorized Mercedes-Benz Light Truck
Center only. Please read the instructions
fully before beginning operation and only
undertake it if you feel fully capable of
performing all of the tasks involved as de-
scribed in these instructions. Observe all
safety instructions and precautions when
handling automotive batteries
(page 507). Performing the tasks involved
incorrectly can cause damage to the vehicle
and impair the operating safety of the
vehicle, and/or cause severe injury to you
or others.
i
With a disconnected battery you will no
longer be able to turn the SmartKey in the starter
switch and pressing the KEYLESS-GO*
start/stop button will have no effect.
i
If your battery is discharged, the vehicle
must be jump started (
page 515) using the
jump start contacts in the engine compartment,
or an accessory battery charge unit* approved
by Mercedes-Benz must be connected using the
jump start contacts in the engine compartment
(see separate instructions for the accessory bat-
tery charge unit*) before any of the following
steps can be performed. If the battery cannot be
jumped or charged, please contact an
authorized Mercedes-Benz Light Truck Center.

522 Practical hintsFusesThe electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses. They are included with the
vehicle tool kit (
page 469):
Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.
Spare fuses
Fuse extractor
The electrical fuses are located in different
fuse boxes:
Fuse box in engine compartment
(page 523)
Fuse box in cargo compartment
(page 523)
Fuse box in passenger compartment
(page 524)Before replacing fuses:
Apply parking brake (
page 65).
Make sure the automatic transmission
is set toP (
page 187).
The gear position indicator in the multi-
function display should be on
P.
Turn off all electrical consumers.
Turn off the engine (
page 40).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.
Warning!
G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an au-
thorized Mercedes-Benz Light Truck Center.i
A blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart. Any
Mercedes-Light Truck Center will be glad to
advise you on this subject.
