Practical hints
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.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
cargo compartment with the vehicle tool
kit (
୴ page 448).
The electrical fuses are located in different
fuse boxes:
ț Fuse box in engine compartment
(
୴ page 505)
ț Fuse box in cargo compartment
(
୴ page 505)
ț Fuse box in passenger compartment
(
୴ page 506)
Before replacing fuses:
̈ Apply parking brake (୴ page 65).
̈ Make sure the automatic transmission
is set to P (
୴ page 185).
The gear position indicator in the multi-
function display should be on
P
.
̈ Turn off all electrical consumers.
̈ Turn off the engine (୴ page 40).
̈ Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
̈ Open the driver’s door (this puts
the starter switch in position 0,
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.
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.
