reservoir.Use windshield washer fluid. If windshield washer
fluid is unavailable use clean water.
In areas where water freezes in winter, use an anti-
freeze type windshield washer fluid. SUBARU Wind-

Replacement of windshield wiper blades
Grease, wax, insects, or other material on the wind-
shield or the wiper blade results in jerky wiper
operation and streaking on the glass. If you cannot
remove the streaks after operating the windshield
washer or if the wiper operation is jerky, clean the
outer surface of the windshield (or rear window) andthe wiper blades using a sponge or soft cloth with a
neutral detergent or mild-abrasive cleaner. After
cleaning, rinse the windshield and wiper blades with
clean water. The windshield is clean if beads do not
form when you rinse the windshield with water.
CAUTION
Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzene. This will cause deterioration of the wiperblades.
If you cannot eliminate the streaking even after fol-
lowing this method, replace the wiper blades using
the following procedures:
1. Raise the wiper arm off the windshield.

1) Stopper
2. Remove the wiper blade assembly by holding its
pivot area and pushing it in the direction shown by
the arrow while depressing the wiper blade stopper.

Battery
WARNING
Before beginning work on or near any bat-
tery, be sure to extinguish all cigarettes,
matches, and lighters. Never expose a batteryto an open flame or electric sparks. Batteriesgive off a gas which is highly flammable andexplosive. For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a
battery. Do not let battery fluid contact eyes, skin,
fabrics, or paint because battery fluid is a cor- rosive acid. If battery fluid gets on your skin or in your eyes, immediately flush the area
with water thoroughly. Seek medical help im-
mediately if acid has entered the eyes.If battery fluid is accidentally swallowed,
immediately drink a large amount of milk or
water, and seek medical attention immediately. To lessen the risk of sparks, remove rings,
metal watchbands, and other metal jewelry.
Never allow metal tools to contact the positive because a short circuit will result.
Keep everyone including children away
from the battery. Charge the battery in a well-ventilated area.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
Wash
hands after handling.
CAUTION
Never use more than 10 amperes when charg- ing the battery because it will shorten batterylife.

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 dis-
tilled water. 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.
HGB006BA
The one is located under the instrument panel be- hind the fuse box cover on the driver ’s seat side.

HS0208
1) Fuse puller 2) Spare fuse
The fuse puller and spare fuses are stored in the main fuse box cover in the engine compartment.
If any lights, accessories or other electrical controls
do not operate, inspect the corresponding fuse. If a
fuse has blown, replace it.
HS0204
A) Good B) Blown
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 fuseHB8003CA
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.
