Replacement of brake pad and lining
The right front disc brake and the right rear disc brake
have an audible wear indicators on the brake pads. If
the brake pads wear close to their service limit, the
wear indicator makes a very audible scraping noise
when the brake pedal is applied.
If you hear this scraping noise each time you apply the
brake pedal, have the brake pads serviced by your
SUBARU dealer as soon as possible.
If you continue to drive despite the scraping
noise from the audible brake pad wear indica-
tor, it will result in the need for costly brake ro-
tor repair or replacement.
„ Breaking-in of new brake pads and lin- ings
When replacing the brake pad or lining, use only gen-
uine SUBARU parts. After replacement, the new parts
must be broken in as follows: T Brake pad and lining
While maintaining a speed of 30 to 40 mph (50 to 65
km/h), step on the brake pedal lightly. Repeat this five
or more times. T Parking brake lining
1. Drive the vehicle at a speed of about 22 mph (35 km/h).
2. With the parking brake release button pushed in,
pull the parking brake lever SLOWLY and GENTLY.
(Pulling with a force of approximately 33 lbs [147 N, 15kg].)
3. Drive the vehicle for about 220 yards (200 meters)

ly and to rapidly become hot. A sharp increase
in temperature could cause tread separation,
and destruction of the tires. The resulting loss
of vehicle control could lead to an accident.
„ Wheel balance
Each wheel was correctly balanced when your vehicle
was new, but the wheels will become unbalanced as
the tires become worn during use. Wheel imbalance
causes the steering wheel to vibrate slightly at certain
vehicle speeds and detracts from the vehicle’s
straight-line stability. It can also cause steering and
suspension system problems and abnormal tire wear.
If you suspect that the wheels are not correctly bal-
anced, have them checked and adjusted by your
SUBARU dealer. Also have them adjusted after tire re-
pairs and after tire rotation.
NOTE
Loss of correct wheel alignment* causes the tires
to wear on one side and reduces the vehicle’s run-
ning stability. Contact your SUBARU dealer if you
notice abnormal tire wear.
*: The suspension system is designed to hold each wheel at
a certain alignment (relative to the other wheels and to the
road) for optimum straight-line stability and cornering perfor- mance. „
Wear indicators
A) New tread
B) Worn tread
1) Tread wear indicator
Each tire incorporates a tread wear indicator, which
becomes visible when the depth of the tread grooves
decreases to 0.063 in (1.6 mm). A tire must be re-
placed when the tread wear indicator appears as a
solid band across the tread.

Intercooler water spray (WRX-STi)
Add water to the intercooler water spray tank when the
intercooler water spray warning light in the combina-
tion meter comes on. The warning light comes on
when the water in the tank has decreased to approxi-
mately 0.4 liters (0.4 US qt, 0.4 Imp qt). The tank is located on the right hand side of the trunk.
NOTE y
Use only pure water for refilling.
y In cold weather (when you do not use the inter-
cooler water spray), keep the tank half-empty in
case the water freezes. A larger amount of water
could break the tank if it froze.

Battery
yBefore beginning work on or near any bat-
tery, be sure to extinguish all cigarettes, match-
es, and lighters. Never expose a battery to an
open flame or electric sparks. Batteries give off
a gas which is highly flammable and explosive.y For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a bat-tery. y 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 immedi-
ately if acid has entered the eyes.
If battery fluid is accidentally swallowed, imme-
diately drink a large amount of milk or water,
and seek medical attention immediately. y 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 anything connected to it
WHILE you are at the same time in contact with any other metallic portion of the vehicle be-
cause a short circuit will result.y
Keep everyone including children away from
the battery.y Charge the battery in a well-ventilated area.
y Battery posts, terminals and related accesso-
ries contain lead and lead compounds, chemi-
cals 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.

Main fuse
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 elec-
trical component fails to operate (except 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 ve-
hicle. Such accessories may cause the electronic sys-
tem to malfunction if they are incorrectly installed or if
they are not suited for the vehicle.
