Practical hints
Jump starting
 Jump starting
If the battery is disc harged, the engine can
be started with jumper cables and the
battery of another vehicle. Observe the
following:

Jump starting should only be performed
using the jump-start terminals located
in the engine compartment
(
page 398).

Jump starting should only be performed
when the engine and catalytic
converter are cold.

Do not start the engine if the battery is
frozen. Let the battery thaw out first.

Only jump start from batteries with the
same voltage rating (12 V). Jump start-
ing with a higher voltage battery could
damage the vehicle’s electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.

Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.

Always make sure the jumper cables
are not on or near pulleys, fans, or
other parts that move when an engine
is started or running.
Warning!G
Failure to follow thes e directions will cause
damage to the electr onic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also pr oduce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it explod ing, causing personal
injury.
Read all instructions before proceeding.
!Do not tow-start the vehicle.
!Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick charge unit.
If the engine does not run after several unsuc-
cessful starting attempts, have it checked at the
nearest authorized Mercedes-Benz Light Truck
Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the
catalytic converter.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still
attached to a battery.

Practical hints
Fuses
 Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating. If a newly inserted fuse blows again, have
the cause determined and rectified at an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses.

Fuse chart
The fuse chart explains the fuse
allocation and fuse amperages.
The fuse chart is located in the main
fuse box in the passenger compart-
ment (
page 404).

Spare fuses
The spare fuses are located in the main
fuse box in the passenger compart-
ment (
page 404).

Fuse extractor
The fuse extractor is located in the
vehicle tool kit in the rear footwell
(
page 364).The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 404)

in the front passenger footwell
(
page 404)

in the middle tunnel (page 405)

in the battery box (page 406)
Before replacing fuses:
Apply parking brake (page 62).
Make sure the gear selector lever is set
to park position P (
page 162).
Turn off all electrical consumers.
Turn off the engine (page 64).
Remove the SmartKey from the starter
switch.
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
approved 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 at an
authorized Mercedes-Benz Light Truck
Center.
iA blown fuse must be replaced by an
appropriate 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.
