Preparing the vehicle
Prepare the vehicle as described
(page 478).

Take the wheel wrench and the vehicle
jack from the vehicle tool kit
(page 455).

Take the spare wheel from the wheel
well under the cargo compartment

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One wheel chock is included with the
vehicle tool kit (
page 455).
When changing wheel on a level surface:

Place the wheel chock in front of and
another sizable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chock and another sizable
object as follows:

Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the axle not
being worked on.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

Stranded vehicle
Freeing a stranded vehicle, on which the
wheels are dug into sand or mud, should
be done with the greatest of care, especial-
ly if the vehicle is heavily loaded.
Avoid pulling the vehicle abruptly or diago-
nally, since it could result in damage to the
chassis alignment.
Never try to free a vehicle that is still cou-
pled to a trailer.
If possible, a vehicle equipped with trailer
hitch receiver should be pulled backward
in its own previously made tracks.
Warning!
G
In order to avoid possible serious burns or
injury, use extreme caution when removing
the cover, because the rear exhaust pipe is
extremely hot.

503 Practical hintsFuses
Fuses
The electrical fuses in your vehicle serve to
stop the supply of electricity to a device
that is malfunctioning. This helps to
prevent damage to the other vehicle
electronics. If a fuse is blown, the compo-
nents and systems secured by that fuse
will stop operating.
The following aids are available to help you
change fuses. They are included with the
vehicle tool kit (
page 455):


Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.


Spare fuses


Fuse extractor
Warning!
G
Only use fuses approved for Mercedes-Benz
with the specified amperage for the system
in question. Otherwise, a short circuit could
result and cause a fire.
!Only install fuses that have been tested
and approved by Mercedes-Benz and
that have the specified amperage
rating. Otherwise, electrical parts or
systems could be damaged.
Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Light Truck Center.
