11-44Maintenance and service
1) Cap
2) Upper level
3) Lower level
It is unnecessary to periodically check the
battery fluid level or periodically refill with
distilled water.
However, if the battery fluid level is below
the lower level, remove the cap. Fill to the
upper level with distilled water.
CAUTION
Never use more than 10 amperes
when charging the battery because
it will shorten battery life. Fuses
CAUTION
Never replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.
The fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes.
One is located under the instrument panel
behind the fuse box cover on the driver ’s
seat side. To remove the cover, pull it out.
The other one is housed in the engine compartment.
The spare fuses are stored in the main
fuse box cover in the engine compart-ment.

The fuse puller is stored in the main fuse
box in the engine compartment.
1) Good
2) 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 acces- sories.
2. Remove the cover.
3. Determine which fuse may be blown.
Look at the back side of each fuse box
cover and refer to “Fuses and circuits ”
F 12-6.
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 samerating.
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 overload to prevent damage to
the wiring harness and electrical equip-
ment. Check the main fuses if any
electrical component fails to operate (ex-
cept the starter motor) and other fuses are
good. A melted main fuse must be
replaced. Use only replacements with 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. Maintenance and service
