Clutch pedal (MT vehicles)
Check the clutch pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet ”.
Checking the clutch function
Check the clutch engagement and disen-
gagement.
1. With the engine idling, check that there
are no abnormal noises when the clutch
pedal is depressed, and that shifting into
1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal
slowly to check that the engine and trans-
mission smoothly couple without any sign
of slippage.
Checking the clutch pedal
free play
1) 0.16 – 0.51 in (4.0 –13.0 mm)
Lightly press the clutch pedal down with
your finger until you feel resistance, and
check the free play.
If the free play is not within proper specifi-
cation, contact your SUBARU dealer.
Replacement of brake pad
and lining
The right front disc brake and the right rear
disc brake have audible wear indicators
on the brake pads. If the brake pads wear
close to their service limit, the wear indica-
tor 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.

Breaking-in of new brake
pads and linings
When replacing the brake pad or lining,
use only genuine SUBARU parts. After re-
placement, the new parts must be broken
in as follows:
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.
Parking brake lining
1. Drive the vehicle at a speed of approx-
imately 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, 15
kg].)
3. Drive the vehicle for approximately 220
yards (200 meters) in this condition.
4. Wait 5 to 10 minutes for the parking brake to cool down. Repeat this proce-
dure.
5. Check the parking brake stroke. If the
parking brake stroke is out of the specified
range, adjust it by turning the adjusting nut
located on the parking brake lever.
Parking brake stroke:
7
– 8 notches / 44 lbs (196 N, 20 kg)
Parking brake stroke
Check the parking brake stroke according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet ”. When
the parking brake is properly adjusted,
braking power is fully applied by pulling
the lever up seven to eight notches gently
but firmly (approximately 44 lbs [196 N, 20
kg]). If the parking brake lever stroke is not
within the specified range, have the brake
system checked and adjusted at your
SUBARU dealer.
If you continue to drive despite the
scraping noise from the audible
brake pad wear indicator, it will re-
sult in the need for costly brake ro-
tor repair or replacement.
A safe location and situation should
be selected for break-in driving.
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be cer-
tain to pull the lever up slowly and
gently.

11-32 Maintenance and service
Abnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher.Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface bumps and
dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for
the vehicle when fully loaded and for the
vehicle when towing a trailer, adjust the
tire pressures to the values that match
current loading conditions.
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 caus-
es 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 sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not cor-
rectly balanced, have them checked and
adjusted by your SUBARU dealer. Also
have them adjusted after tire repairs and
after tire rotation.
NOTE
Loss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle ’s running stability.
B00051B00052
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of vehi-
cle control could lead to an acci-
dent.

Maintenance and service 11-35
Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
When any of the wheels is removed and
replaced for tire rotation or to change a
flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose, tight-
en it to the specified torque.
Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
Never let the wheel rub against sharp
protrusions or curbs.
Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel.
When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine SUBARU parts
designed for aluminum wheels.
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 freez-
es. A larger amount of water could
break the tank if it froze.

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.
Battery
B00066
B00067
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) Fuse puller
4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown, re-
place it with a spare fuse of the same rat-
ing.
6. If the same fuse blows again, this indi-
cates that its system has a problem. Con-
tact your SUBARU dealer for repairs.
Main fuse
Main fuse box
The main fuses are designed to melt dur-
ing an overload 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 replacements with the same speci-
fied 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 be-
fore installing fog lights or any other elec-
trical equipment in your vehicle. Such ac-
cessories may cause the electronic sys-
tem to malfunction if they are incorrectly
installed or if they are not suited for the ve-
hicle.

Headlights (WRX-STI)
Replace any bulb only with a new
bulb of the specified wattage. Using
a bulb of different wattage could re-
sult in a fire.
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 re-
place them. Neither should you at-
tempt to replace the high-beam
bulbs, remove/refit the headlight as-
semblies, or remove any headlight-
assembly components. For replace-
ment of the headlight bulbs (low-
beam and high-beam), removal and
installation of the headlight assem-
blies, and removal of headlight-as-
sembly components, contact your
SUBARU dealer.

11-46 Maintenance and service

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.

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.
