WARNING
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Using fuses which have not been
approved or attempting to repair or bridge
faulty fuses could cause the fuse to be over-
loaded and result in a fire. Have the cause
traced and rectified at a qualified specialist
workshop.
! 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
Service Centre. Before replacing a fuse
X Secure the vehicle against rolling away
(Y page 164).
X Switch off all electrical consumers.
X Turn the key to position 0in the ignition
lock and remove it (Y page 147).
or
X On vehicles with KEYLESS-GO, make sure
the ignition is switched off (Y page 147).
All indicator lamps in the instrument cluster
must be off.
The fuses are located in various fuse boxes:
R fuse box on the driver's side of the dash-
board
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 stowage well under the lug-
gage compartment floor on the right-hand
side of the vehicle, when viewed in the
