472 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 at an
authorized Mercedes-Benz Center.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
main fuse box in the passenger compart-
ment (
page 472).
The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 472)

on the driver’s side of the engine com-
partment (
page 473)

in the trunk (page 474)
Before replacing fuses:
Apply the parking brake (page 59).
Make sure the gear selector lever is set
to position P (
page 174).
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.
Fuse box in passenger compartment
The fuse box is located in the passenger
compartment on the driver’s side of the
cockpit.
1Fuse box coverWarning!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 at an au-
thorized 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.
iIn case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-Benz
Center.
!Do not use sharp objects such as a screw
driver to open the fuse box cover1 in the
cockpit, as this could damage it.
