704 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 by an
authorized Mercedes-Benz Center.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
trunk with the vehicle tool kit
(
page 668).
Depending on vehicle production date, the
following aids are available to help you re-
place fuses. If so equipped, they are locat-
ed in the trunk with the vehicle tool kit
(
page 668):

Spare fuses

Fuse extractorThe electrical fuses are located in different
fuse boxes:

in the dashboard on the passenger side
(

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 (
page 695) when you are working on
the fuses.
iA 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.iShould your vehicle not be equipped with a
fuse extractor or spare fuses please contact a
Mercedes-Benz Center or Roadside Assistance
in case of a blown fuse.
