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.

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.

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.
