Battery
WARNING
. Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and light-
ers. Never expose a battery to an
open flame or electric sparks.
Batteries give off a gas which is
highly flammable and explosive.
. For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when work-
ing near any battery. Never lean
over a battery.
. Do not let battery fluid contact
eyes, skin, fabrics, or paint be-
cause battery fluid is a corrosive
acid. If battery fluid gets on your
skin or in your eyes, immediately
flush the area with water thor-
oughly. Seek medical help imme-
diately if acid has entered theeyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention im-
mediately.
. To lessen the risk of sparks, remove rings, metal watchbands,
and other metal jewelry. Never
allow metal tools to contact the
positive battery terminal and any-
thing connected to it WHILE you
are at the same time in contact
with any other metallic portion of
the vehicle because a short cir-
cuit will result.
. Keep everyone including children
away from the battery.
. Charge the battery in a well-
ventilated area.
. Battery posts, terminals and re-
lated accessories contain lead
and lead compounds, chemicals
known to the State of California
to cause cancer and reproductive
harm. Batteries also contain
other chemicals known to the
State of California to cause can-
cer.
Wash hands after handling.
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 Maintenance and service

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 12-12.
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. Installation of accessories
Always consult your SUBARU dealer
before installing fog lights or any other
electrical equipment in your vehicle. Such
accessories may cause the electronic
system to malfunction if they are incor-
rectly installed or if they are not suited for
the vehicle.

Replacing bulbs
WARNING
Bulbs may become very hot while
illuminated. Before replacing bulbs,
turn off the lights and wait until the
bulbs cool down. Otherwise, there is
a risk of sustaining a burn injury.
CAUTION
Replace any bulb only with a new
bulb of the specified wattage. Using
a bulb of different wattage could
result in a fire. For the specified
wattage of each bulb, refer to “Bulb
chart ”F 12-16.
& Headlights (models with HID headlights)
WARNING
High-intensity-discharge (HID) bulbs
are used for the low beams of the
headlights. These HID bulbs use an
extremely high voltage. To avoid the
risk of an electric shock that could
result in serious injury, observe the following precautions. .
Do not replace any headlight
bulbs (both low beam and high
beam) by yourself.
. Do not remove/restore the head-
light assemblies by yourself.
. Do not remove any headlight-
assembly components by your-self.
For replacement, contact your
SUBARU dealer.
& Headlights (models without
HID headlights)
CAUTION
Halogen headlight bulbs become
very hot while in use. If you touch
the bulb surface with bare hands or
greasy gloves, fingerprints or
grease on the bulb surface will
develop into hot spots, causing the
bulb to break. If there are finger
prints or grease on the bulb surface,
wipe them away with a soft cloth
moistened with alcohol. NOTE .
If headlight aiming is required, con-
sult your SUBARU dealer for proper
adjustment of the headlight aim.. It may be difficult to replace the
bulbs. Have the bulbs replaced by your
SUBARU dealer if necessary. ! Low beam light bulbs
