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 (
The electrical fuses are located in different 
fuse boxes:
Fuse box in passenger compartment 
(
Fuse box in engine compartment 
(
Fuse box in trunk (
Before replacing fuses:
Depress the parking brake 
(
Make sure the manual transmission is 
in Neutral (
transmission* is set to P (
The gear position indicator in the ta-
chometer display should be on P.
Turn off all electrical consumers.
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 (
page 448) when you are working on 
the fuses.

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