428 Practical hintsFusesThe 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 fuse box
in the passenger compartment
(page 429). The fuse chart explains
the fuse allocation and fuse amperag-
es.
Spare fuses
Spare fuses are located in the vehicle
tool kit in the trunk (
page 393).
Fuse extractor
The fuse extractor is located in the ve-
hicle tool kit in the trunk (
page 393).The electrical fuses are located in different
fuse boxes:
Main fuse box in passenger compart-
ment (
page 429)
Fuse box in trunk (
page 429)
Before replacing fuses:
Apply the parking brake (
page 59).
Make sure the gear selector lever is set
to position P (
page 171).
Turn off all electrical consumers.
Turn off the engine (
page 60).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door.
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.
