Electrical fuses
Important safety notes
G
WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may
result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified new
fuses of the correct amperage.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Only use fuses marked with an
"S". Components or systems could other-
wise be damaged.
The fuses in your vehicle serve to disconnect
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and fuse rating. The fuse ratings
are listed in the fuse allocation chart.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
Before replacing a fuse
X Secure the vehicle against rolling away
(
Y page 162).
X Switch off all electrical consumers.
X Turn the key to position 0 in the ignition
lock and remove it ( Y page 143). All indi-
cator lamps in the instrument cluster must
be off.
The fuses are located in various fuse boxes:
R
fuse box in the engine compartment on the
left-hand side of the vehicle, when viewed
in the direction of travel
R
fuse box in the front-passenger footwell
