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. Otherwise, components or sys-
tems could 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 Ser-
vice Centre. Before replacing a fuse
X Secure the vehicle against rolling away
(Y page 175).
X Switch off all electrical consumers.
X Turn the key to position 0in the ignition
lock and remove it (Y page 155).
or
X On vehicles with KEYLESS-GO, make sure
the ignition is switched off (Y page 155).All indicator 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
right-hand side of the vehicle, when viewed
in the direction of travel
R dashboard fuse box
R fuse box in the rear compartment on the
right-hand side of the vehicle, when viewed
in the direction of travel
The fuse allocation chart is located in the
vehicle tool kit in the stowage compartment
under the boot floor (Y page 577). Dashboard fuse box

board. You could damage the dashboard or
the cover.
! Make sure that no moisture can enter the
fuse box when the cover is open.
