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:

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.
