471 Practical hintsFuses
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 Center.
The following aids are available to help you
replace fuses.
Fuse chart
The fuse chart is located in the main
fuse box in the passenger compart-
ment (
page 472). The fuse chart ex-
plains the fuse allocation and fuse
amperages.
Spare fuses
Spare fuses are located in the vehicle
tool kit in the cargo compartment
(page 430).
Fuse extractor
The fuse extractor is located in the ve-
hicle tool kit in the cargo compartment
(page 430).The electrical fuses are located in different
fuse boxes:
in the passenger compartment on the
driver’s side (
page 472)
in the cargo compartment
(page 472)

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
authorized Mercedes-Benz 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 Center will be glad to advise
you on this subject.
