Brake fluid „ Checking the fluid level
Check the fluid level monthly.
Check the fluid level on the outside of the
reservoir. If the level is below “MIN”, add
the recommended brake fluid to “MAX”. Use only brake fluid from a sealed con-
tainer.
„ Recommended brake fluid FMVSS No. 116, fresh DOT 3 or 4 brake flu-

y Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake fluid
gets in your eyes, immediately
flush them thoroughly with clean
water. For safety, when perform-
ing this work, wearing eye protec-
tion is advisable.
y Brake fluid absorbs moisture from
the air. Any absorbed moisture
can cause a dangerous loss of
braking performance.
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
brake fluid togeth er. Also, avoid
mixing DOT 3 and DOT 4 brake flu-
ids even if they are of the same
brand. y When adding brake fluid, be care-
ful not to allow any dirt into the
reservoir.
y Never 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.

Clutch fluid (MT vehicles) „ Checking the fluid level
Check the fluid level on the outside of the
reservoir. If the leve l is below “MIN” level
mark, add the recommended clutch fluid
to “MAX” level mark.
Use only clutch fluid from a sealed con-
tainer. „ Recommended clutch fluid FMVSS No. 116, fresh DOT 3 or 4 brake flu-
id
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.
y Clutch 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 a llow any dirt into
the tank. y Never splash the clutch fluid over
painted surfaces or rubber parts.
Alcohol contained in the clutch
fluid may damage them.
y Be careful not to spill clutch fluid
when adding it. If clutch fluid
touches the exhaus t pipe, it may
cause a bad smell, smoke, and/or
a fire. If clutch fluid gets on the ex-
haust pipe, be sure to wipe it off.

Brake booster If 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. Brake pedal Check the brake pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet”.
„ Checking the brake pedal free
play
1) 0.02 – 0.08 in (0.5 – 2.0 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly pull the
brake pedal up with one finger to check
the free play with a force of less than 2 lbs
(10 N, 1 kg).
If the free play is not within proper specifi-
cation, contact your SUBARU dealer. „ Checking the brake pedal re-
serve distance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approxi-
mately 66 lbs (294 N, 30 kg) and measure
the distance between the upper surface of
the pedal pad and the floor.
When the measurement is smaller than
the specification, or when the pedal does
not operate smoothly, contact with your
SUBARU dealer.1 B003231 B00324

„ Checking the clutch functionCheck 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

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 time1 B00323
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.

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
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:
5 – 6 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 five to six 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.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. B00127

– CONTINUED –Tires and wheels „ Types of tiresYou should be familiar with type of tires
present on your vehicle.
T All season tires
The factory-installed ti res 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 ti res, be sure to re- place all four tires.
T Winter (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 pressure monitoring sys-
tem (TPMS) (if equipped) The tire pressure mo nitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the ve-
hicle is driven. Also, this system may not
react immediately to a sudden drop in tire
pressure (for example, a blow-out caused
by running over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to come on. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
placard. Specifically, inflate them by an
extra 1 psi (6.9 kPa, 0.07 kgf/cm 2
) for ev- ery difference of 10 ° F (5.6 ° C) between the
temperature in the garage and the tem-
perature outside. By way of example, the
following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 60 ° F (15.6 ° C).
Standard tire pressures:
Front: 32 psi (220 kPa, 2.2 kgf/cm 2
)
Rear: 30 psi (210 kPa, 2.1 kgf/cm 2
)
Garage temperature: 60 ° F (15.6 ° C)
If the low tire pressure warning light
comes on when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light Outside

goes off a few minutes later. If the low tire
pressure warning light does not go off, the
tire pressure monitoring system may not
be functioning normally. In this event, go
to a SUBARU dealer to have the system
inspected as soon as possible.
While the vehicle is driven, friction be-
tween tires and the road surface causes
the tires to warm up. After illumination of
the low tire pressure warning light, any in-
crease in the tire pressures caused by an
increase in the outside air temperature or
by an increase in the temperature in the
tires can cause the low tire pressure warn-
ing light to go off.
System resetting is necessary when the
wheels are changed (for example, a
switch to snow tires) and new TPMS
valves are installed on the newly fitted
wheels. Have this work performed by a
SUBARU dealer following wheel replace-
ment.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS will not fully function and the warning light
in the instrument panel will flash.
When a tire is replaced, adjustments are
necessary to ensure continued normal op-
eration of the tire pr essure monitoring sys-
tem. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
„ Tire inspection Check 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.
NOTE y When the wheels and tires strikeIf the low tire pressure warning light
does not come on br iefly after the ig-
nition switch is turned ON or the
light is flashing, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
If this light comes on while driving,
never brake suddenly and keep driv-
ing straight ahead while gradually
reducing speed. Then slowly pull off
the road to a safe place. Otherwise
an accident involving serious vehi-
cle damage and serious personal in-
jury could occur. If this light still comes on while driv-
ing after adjusting the tire pressure,
a tire may have significant damage
and a fast leak that causes the tire to
lose air rapidly. If you have a flat tire,
replace it with a spare tire as soon
as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will flash. This in-
dicates the TPMS is unable to moni-
tor all four road wheels. Contact
your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light flashes, promptly contact a
SUBARU dealer to have the system
inspected.

– CONTINUED –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 no t to mistakenly re-
lease air from a warm tire to reduce its
pressure. NOTE y 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).
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. B00128
Do not let air out of warm tires to ad-
just pressure. Doing so will result in
low tire pressure.

11 - 3 6 Maintenance and service
y Correct 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.B00050 B00051
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. B00052

– CONTINUED –„ 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-l ine 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.
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 indicators
1) New tread
2) Worn tread
3) Tread wear indicator
Each 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. NOTE For safety, inspect th e tire tread regu-
larly and replace the tires before their
tread wear indicators become visible.
„ Tire rotation12 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.
