424 Practical hintsFusesThe 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 by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses. They are located in the trunk
with the vehicle tool kit (
page 388).


Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.


Spare fuses

The electrical fuses are located in different
fuse boxes:


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

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 by an
authorized Mercedes-Benz Centeri
A blown fuse must be replaced by an appro-
piate 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.
