Intercooler water spray (WRX-STI)
Add water to the intercooler water spray
tank when the intercooler water spray
warning light in the combination meter
comes on. The warning light comes on
when the water in the tank has decreased
to approximately 0.4 liters (0.4 US qt, 0.4
Imp qt).
The tank is located on the right-hand side
of the trunk. NOTE .Use only pure water for refilling.
. In cold weather (when you do not
use the intercooler water spray), keep
the tank half-empty in case the water
freezes. A larger amount of water could
break the tank if it froze. Windshield washer fluid
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank.

. 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.

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.

& Headlights (WRX-STI)
WARNING
High-intensity-discharge (HID) bulbs
are used for the low beams of the
headlights on the WRX-STI. These
HID bulbs use an extremely high
voltage. To avoid the risk of an
electric shock and resulting serious
injury, you should not attempt to
replace them. Neither should you
attempt to replace the high-beam
bulbs, remove/refit the headlight
assemblies, or remove any head-
light-assembly components. For re-
placement of the headlight bulbs
(low-beam and high-beam), removal
and installation of the headlight
assemblies, and removal of head-
light-assembly components, contact
your SUBARU dealer.

CAUTION
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
develop 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.
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
