Fuses - Mercedes-Benz 2009 M-Class Operator's Manual

Fuses

Introduction
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.
G Warning!
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.
A 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.
i In case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-
Benz Center.
If a newly inserted fuse blows again, have the
cause determined and rectified by an
authorized Mercedes-Benz Center.
A fuse chart is located in the cargo
compartment with the vehicle tool kit
( Y page 298). The fuse chart explains the fuse
allocation and fuse amperages.
