CHANGING A FUSE
Procedure for replacing a faulty fuse
with a new fuse to rectify a failure of
the corresponding function.
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
A that is pro-
vided in the fuse housing fl ap, which
also contains spare fuses.
