Clutch fluid (MT vehicles)„Checking the fluid levelCheck the fluid level on the outside of the
reservoir. If the level is below “MIN” level
mark, add the recommended clutch fluid
to “MAX” level mark.
Use only clutch fluid from a sealed con-
tainer.
yNever splash the brake fluid over
painted surfaces or rubber parts.
Alcohol contained in the brake flu-
id may damage them.
y Be careful not to spill brake fluid
when adding it. If brake fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If brake fluid gets on the ex-
haust pipe, be sure to wipe it off.

Never let clutch fluid contact your
eyes because clutch fluid can be
harmful to your eyes. If clutch fluid
gets in your eyes, immediately flush
them thoroughly with clean water.
For safety, when performing this
work, wearing eye protection is ad-
visable.
yClutch fluid absorbs moisture
from the air. Any absorbed mois-
ture can cause improper clutch
operation.
y If the vehicle requires frequent re-
filling, there may be a leak. If you
suspect a problem, have the vehi-
cle checked at your SUBARU
dealer.
y Never use different brands of
clutch fluid together.
y When clutch fluid is added, be
careful not to allow any dirt into
the tank.

Brake boosterIf the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move slight-
ly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for ap-
proximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake boost-
er operates properly if the pedal stroke de-
creases with each depression.

Maintenance and service
Hill holder (MT vehicles – if equipped)Ensure that the hill holder operates prop-
erly under the following circumstances:
1. Stop the vehicle on an uphill grade by
depressing the brake pedal and clutch
pedal, with the engine running.
2. Make sure that the vehicle does not
move backward even after the brake ped-
al is released.
3. Then make sure the vehicle starts
climbing the grade by following the normal
starting procedures.
If the hill holder does not operate as de-
scribed above, contact with your SUBARU
dealer.
Replacement of brake pad and liningThe 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 liningsWhen replacing the brake pad or lining,
use only genuine SUBARU parts. After re-
placement, 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 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

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.

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 strokeCheck 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.
Tires and wheels„Types of tiresYou should be familiar with type of tires
present on your vehicle.
T All season tires
The factory-installed tires on your new ve-
hicle are all season tires.
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road con-
ditions. However all season tires do not of-
fer as much traction performance as win-
ter (snow) tires in heavy or loose snow or
on icy roads.
All season tires are identified by “ALL
SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
T Summer tires
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-cov-
ered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to re-
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.

place all four tires.
TWinter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as sum-
mer tires and all season tires on roads oth-
er than snow-covered and icy roads. „ Tire inspectionCheck on a daily basis that the tires are
free from serious damage, nails, and
stones. At the same time, check the tires
for abnormal wear.
Contact your SUBARU dealer immediate-
ly if you find any problem.NOTEyWhen the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
that cannot be seen with the naked eye.
This type of damage does not become
evident until time has passed. Try not
to drive over curbs, potholes or on oth-
er rough surfaces. If doing so is un-
avoidable, keep the vehicle’s speed
down to a walking pace or less, and ap-
proach the curbs as squarely as possi-
ble. Also, make sure the tires are not
pressed against the curb when you park the vehicle.
y
If you feel unusual vibration while
driving or find it difficult to steer the ve-
hicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized
SUBARU dealer and have the vehicle
inspected.
„ Tire pressures and wearMaintaining the correct tire pressures
helps to maximize the tires’ service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) and before any long
journey. Check the tire pressures when the tires
are cold. Use a pressure gauge to adjust
the tire pressures to the values shown on
the tire placard. The tire placard is located
on the door pillar on the driver’s side.
Driving even a short distance warms up
the tires and increases the tire pressures.
Also, the tire pressures are affected by the
outside temperature. It is best to check tire
pressure outdoors before driving the vehi-
cle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to in-
crease. Be careful not to mistakenly re-
lease air from a warm tire to reduce its
pressure.
NOTEy
The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm
2) when the tire becomes warm.
y The tires are considered cold when
the vehicle has been parked for at least
three hours or has been driven less
than one mile (1.6 km).
800221
Do not let air out of warm tires to ad-
just pressure. Doing so will result in
low tire pressure.

Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally.
yCorrect tire pressure (tread worn
evenly)
Roadholding is good, and steering is re-
sponsive. Rolling resistance is low, so fuel
consumption is also lower. y
Abnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher. y
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 balanceEach 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.NOTELoss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability. Contact your SUBARU dealer if you no-
tice 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 indicators1) New tread
2) Worn tread
3) Tread wear indicatorEach tire incorporates a tread wear indica-
tor, which becomes visible when the depth
of the tread grooves decreases to 0.063 in
(1.6 mm). A tire must be replaced when
the tread wear indicator appears as a solid
band across the tread.
NOTEFor safety, inspect tire tread regularly
and replace the tires before their tread
wear indicators become visible.„Tire rotation
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.
12 3
B00327
When a tire’s tread wear indicator
becomes visible, the tire is worn be-
yond the acceptable limit and must
be replaced immediately. With a tire
in this condition, driving at high
speeds in wet weather can cause
the vehicle to hydroplane. The re-
sulting loss of vehicle control can
lead to an accident.

Tire wear varies from wheel to wheel. To
maximize the life of each tire and ensure
that the tires wear uniformly, it is best to
rotate the tires every 7,500 miles (12,500
km). Rotating the tires involves switching
the front and rear tires on the right-hand
side of the vehicle and similarly switching
the front and rear tires on the left-hand
side of the vehicle. (Each tire must be kept
on its original side of the vehicle.)
Replace any damaged or unevenly worn
tire at the time of rotation. After tire rota-
tion, adjust the tire pressures and make
sure the wheel nuts are correctly tight-
ened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose.„Tire replacementThe wheels and tires are important and in-
tegral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires fit-
ted as standard equipment are optimally
matched to the characteristics of the vehi-
cle and were selected to give the best pos-
sible combination of running performance,
ride comfort, and service life. It is essential
for every tire to have a size and construc-
tion matching those shown on the tire placard and to have a speed symbol and
load index matching those shown on the
tire placard.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to re-
place the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU rec-
ommends replacing all four tires at the
same time.
„
Wheel replacementWhen replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.yAll four tires must be the same in
terms of manufacturer, brand
(tread pattern), construction, de-
gree of wear, speed symbol, load
index and size. Mixing tires of dif-
ferent types, sizes or degrees of
wear can result in damage to vehi-
cle’s power train. Use of different
types or sizes of tires can also
dangerously reduce controllabili-
ty and braking performance and
can lead to an accident.yUse only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires. Do-
ing so can dangerously reduce
controllability, resulting in an ac-
cident.

Maintenance and service
Aluminum wheels (if equipped)Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
yWhen 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.
y Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
y Never let the wheel rub against sharp
protrusions or curbs.
y Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel.
y 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.
Windshield washer fluidIf 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.
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could in-
terfere with brake caliper operation
and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of vehi-
cle control could lead to an acci-
dent.
Never use engine coolant as washer
fluid because it could cause paint
damage.
