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.
The fuse chart is located in the fuse box in the
passenger compartment. The fuse chart 288
