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 406).
Spare fuses
The spare fuses are located in the main
fuse box in the passenger compart-
ment (
page 406).
Fuse extractor
The fuse extractor is located in the
vehicle tool kit in the rear footwell
(
page 366).The electrical fuses are located in different
fuse boxes:
in the passenger compartment on the
driver’s side (
page 406)

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

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

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.
