2008 MERCEDES-BENZ CL-Class engine

714 Practical hintsFusesThe 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 681).The electrical fuses are located in different
fuse boxes:


in the dashboard on the passenger side
(page 716)


in the dashboard on the driver’s side
(page 716)


behind the rear center armrest
(page 716)


on the driver’s side of the engine com-
partment (
page 715)


on the passenger side of the engine
compartment (
page 716)
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 705) 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.
i
In case of a blown fuse contact Roadside As-
sistance or an authorized Mercedes-Benz
Center.
