- 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.

- Fit the fuse cover back on.

The individual electrical circuits are protected by fuses. The fuses are located

behind a cover at the left-hand end of the instrument panel.

Two spare fuses and a sticker identifying the fuses are provided on the inside

of the fuse cover. There is also a crank handle for operating the sun roof* by

Caution

Never “repair” damaged fuses and never replace them with fuses with a

higher rating. Failure to comply could result in fire. It could also cause

damage to other parts of the electrical system.

Note

If a newly replaced fuse blows again after a short time, the electrical system

must be checked by a qualified workshop as soon as possible.
