CHANGING A FUSE
Operating procedure for replacing a
faulty fuse with a new fuse to rectify
a failure of the corresponding func-
tion.
There are two fuseboxes under the
dashboard, one fusebox in the en-
gine compartment and another on
the battery.
Changing a fuse
Before replacing a fuse, it is essen-
tial to fi nd the cause of the incident
and to have it rectifi ed. The fuse
identifi cation numbers are indicated
inside the fusebox.
Replace a blown fuse with one of the
same rating (the same colour). Use the special tool

vided in the fuse housing fl ap, which
also contains spare fuses.

In order to resume the use of these
functions immediately, start the engine
and let it run for at least 5 minutes.
A fl at battery prevents the
