Practical hints
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the component(s) and
systems secured by that fuse will stop op-
erating.
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 (
୴ page 457).
The electrical fuses are located in different
fuse boxes:
ț Fuse box in passenger compartment
(
୴ page 457)
ț Fuse box in engine compartment
(
୴ page 457)
ț Fuse box in trunk (୴ page 458)
Before replacing fuses:
̈ Depress the parking brake
(
୴ page 134).
̈ Make sure the manual transmission is
in Neutral (
୴ page 136), automatic
transmission* is set to P (
୴ page 140).
The gear position indicator in the ta-
chometer display should be on P.
̈ Turn off all electrical consumers.
̈ Turn off the engine (୴ page 134).
̈ Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*
(Canada only):
̈ 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 at an au-
thorized 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.
!
Switch off the vehicle’s internal electrical
functions (
୴ page 448) when you are working on
the fuses.

In case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-Benz
Center.
