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 Center.
The following aids are available to help you
replace fuses. They are included with the
vehicle tool kit (
컄 page 473):
ì•« Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.
ì•« Spare fuses
ì•« Fuse extractor
The electrical fuses are located in different
fuse boxes:
ì•« on the passenger side of the engine
compartment (
컄 page 521)
ì•« in the cargo compartment
(
컄 page 521)
ì•« in the passenger compartment
(
컄 page 522)
Before replacing fuses:
왘 Apply the parking brake (컄 page 66).
왘 Make sure automatic transmission is
set to position P (
컄 page 199).
The gear position indicator in the
multifunction display should be on
P
.
왘 Turn off all electrical consumers.
왘 Turn off the engine (컄 page 67).
왘 Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
왘 Open the driver’s door (this puts
the starter switch to position 0,
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
i
A 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.
