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 457). The fuse chart ex-
plains the fuse allocation and fuse
amperages.
Spare fuses
Spare fuses are located in the vehicle
tool kit in the spare wheel well
(
page 404).
Fuse extractor
The fuse extractor is located in the
trunk underneath the trunk floor cover
(
page 405), or
CLK 63 AMG (
page 404).The electrical fuses are located in different
fuse boxes:
in the passenger compartment on the
driver’s side (
page 457)
on the driver’s side of the engine com-
partment (
page 457)
in the trunk (page 458)
Before replacing fuses:

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
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 Center will be glad to advise
you on this subject.
