Vehicle care235Electrical systemFuses
Data on the replacement fuse must match the data on the defective fuse.
There are three fuse boxes in the
vehicle:
■ in the front left of the engine compartment,
■ in left-hand drive vehicles, in the interior behind the storage
compartment, or, in right-hand
drive vehicles, behind the
glovebox,
■ behind a cover on the left side of the
load compartment.
Before replacing a fuse, turn off the
respective switch and the ignition.
There are different kinds of fuses in
the vehicle.
Depending on the type of fuse, a
blown fuse can be recognized by its
melted wire. Do not replace the fuse until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Fuse extractor A fuse extractor may be located in the fuse box in the engine compartment.
