Practical hints
Fuses
̄ 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 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 (
୴ page 632):

tion and fuse amperages.

The electrical fuses are located in different
fuse boxes:
ț in the dashboard on the passenger side

The gear position indicator in the ta-
chometer display should be on P.

̈ Switch off the vehicle’s internal electri-
cal functions (

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 Center.
!
Switch off the vehicle’s internal electrical
functions (
୴ page 658) when you are working on
the fuses.
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.
