4. Align the claws of the plastic support
with the grooves in the blade rubber as-
sembly, then slide the blade rubber as-
sembly into place.
Securely retain both ends of the rubber
with the stoppers on the plastic support ends. If the rubber is not retained properly,
the wiper may scratch the rear window
glass.
5. Install the wiper blade assembly to the
wiper arm. Make sure that it locks in place.
6. Hold the wiper arm by hand and slowly
lower it in position.

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. Bat-
teries give off a gas which is high-
ly flammable and explosive.
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 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 the
eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water, and
seek medical attention immediate-
ly.

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.
Fuses
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 coin tray on the driver ’s seat
side.
To lessen the risk of sparks, re-
move rings, metal watchbands,
and other metal jewelry. Never al-
low metal tools to contact the pos-
itive battery terminal and anything
connected to it WHILE you are at
the same time in contact with any
other metallic portion of the vehi-
cle because a short circuit will re-
sult.
Keep everyone including children
away from the battery.
Charge the battery in a well-venti-
lated area.
Battery posts, terminals and relat-
ed 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 cancer. Wash
hands after handling .
Never use more than 10 amperes
when charging the battery because
it will shorten battery life.

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.

11-46 Maintenance and service
Headlights (Except WRX-STI)
Before replacing the left-hand (battery-
side) high-beam light bulb, remove the
screw that retains the windshield washer
nozzle and tip the windshield washer noz-
zle sideways.
Non-turbo models
Turbo models
Before replacing the right-hand low- or
high-beam light bulb, remove the bolts and remove the air intake duct.
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 your SUBARU dealer re-
place the bulbs if necessary.

B00478
Halogen headlight bulbs become
very hot while in use. If you touch
the bulb surface with bare hands or
greasy gloves, finger prints or
grease on the bulb surface will de-
velop into hot spots and cause 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.
