518 Practical hints
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 by an
authorized Mercedes-Benz Light Truck
Center.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
cargo compartment with the vehicle tool
kit (
page 469).
The electrical fuses are located in different
fuse boxes:

on the passenger side of the engine
compartment (
page 519)

in the cargo compartment
(
page 519)

in the passenger compartment
(
page 520)Before replacing fuses:
Apply the parking brake (page 65).
Make sure automatic transmission is
set to position P (
page 192).
The gear position indicator in the
multifunction display should be on
P.
Turn off all electrical consumers.
Turn off the engine (page 66).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door (this puts
the starter switch to position0,
same as with the SmartKey re-
moved from starter switch). The
driver’s door can then 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
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 by an
authorized 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.
