Notes on changing fuses
The fuses in your vehicle serve to close down
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 value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
required fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. A circuit overload could other-
wise cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
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.
! 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 are located in various fuse boxes:
R dashboard fuse box on the front-passenger
side
R fuse box in the engine compartment on the
right-hand side of the vehicle
R fuse box in the luggage compartment on
the right-hand side of the vehicle
Fuse allocation chart The fuse allocation chart is located with the
vehicle tool kit (Y
page 209) in the stowage
compartment under the luggage compart-
ment floor. 280
