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.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
fuse box in the passenger compartment
(
page 433).
The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 433)

on the driver’s side of the engine
compartment (
page 433)Before replacing fuses:
Apply the parking brake (page 59).
Make sure the gear selector lever* is
set to positionP (
page 157) (manual
transmission to Neutral).
Turn off all electrical consumers.
Turn off the engine (page 61).
Remove the SmartKey from the starter
switch.
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 Center.
iA blown fuse must be replaced by an
appropriate 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.
iIn case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-Benz
Center.
