Fuses
CAUTION
Never replace a fuse with one having a higher
rating or with material other than a fuse be-
cause serious damage or a fire could result.
The fuses are designed to melt during an overload
to prevent damage to the wiring harness and electri-
cal equipment. The fuses are located in two fuseboxes.
One is located under the instrument panel behind the coin tray on the driver ’s seat side.

Maintenance and service

1) Fuse puller 2) Spare fuse
The fuse puller and spare fuses are stored in the
main fuse box cover in the engine compartment.A) Good B) Blown
If any lights, accessories or other electrical controls
do not operate, inspect the corresponding fuse. If a
fuse has blown, replace it.
1. Turn the ignition switch to the “LOCK” position
and turn off all electrical accessories.
2. Remove the cover.
3. Determine which fuse may be blown. The backside of each fuse box cover and the “Fuse and cir-
cuits” section in chapter 12 in this manual show the
circuit for each fuse.

1) Fuse puller
4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown, replace it with a
spare fuse of the same rating.
6. If the same fuse blows again, this indicates that
its system has a problem. Contact your SUBARU
dealer for repairs. Main fuse
Main fuse box
The main fuses are designed to melt during an over-
load to prevent damage to the wiring harness and
electrical equipment. Check the main fuses if any
electrical component fails to operate (except the
starter motor) and other fuses are good. A melted
main fuse must be replaced. Use only replacementswith the same specified rating as the melted main
fuse. If a main fuse blows after it is replaced, have
the electrical system checked by your nearest
SUBARU dealer.
