– Switch off the ignition and the component concerned.
– Remove the fuse box cover ⇒fig. 283.
– Take the plastic clip from inside the fuse cover, fit it onto
the blown fuse, and pull the fuse out.
– Replace the blown fuse (which will have a melted metal
strip) with a new fuse of the same amp rating.The various electrical circuits are protected by fuses. The fuse boxes
are located behind covers on the left and right sides of the dash
panel and in the compartment on the right side of the boot.
A plastic clip for removing the fuses is provided in the fuse cover on
the left side of the dash panel. There is also a sticker listing the fuses
in each of the fuse boxes in the dash panel.

higher rating - risk of fire! It could also cause damage to other parts
of the electrical system.

If a newly replaced fuse blows again after a short time, the electrical
system must be checked by a qualified workshop as soon as
