Fuses
The 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 495):

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

Spare fuses

The electrical fuses are located in different
fuse boxes:

Fuse box in passenger compartment
(
page 546)Before replacing fuses:
Apply parking brake (page 68).
Make sure the automatic transmission
is set toP (
page 194).

function display should be on
P.
Turn off all electrical consumers.

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.
iA 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-Benz Light Truck Center will be glad to
advise you on this subject.
