Maintenance schedule
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the“Warranty and Main-
tenance Booklet ”.
For details of your maintenance schedule,
read the separate “Warranty and Main-
tenance Booklet ”. Maintenance precautions
When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize yourself
with the information provided in this
section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
. Testing of an All-Wheel Drive
vehicle must NEVER be per-
formed on a single two-wheel
dynamometer or similar appara-
tus. Attempting to do so will
result in transmission damage
and in uncontrolled vehicle
movement and may cause an
accident or injuries to persons
nearby.
. Always select a safe area when
performing maintenance on yourvehicle. .
Always be very careful to avoid
injury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, batteryacid.
. Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
. Always use the proper tools and
make certain that they are wellmaintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
a safety stands to support thevehicle.
. Never keep the engine running in
a poorly ventilated area, such as
a garage or other closed areas.
. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only
by your SUBARU dealer.
. Wear adequate eye protection to Maintenance and service

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
replacement, 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 moretimes. ! Parking brake lining
WARNING
A safe location and situation should
be selected for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be
certain to pull the lever up slowly
and gently. 1. Drive the vehicle at a speed of
approximately 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 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“
Warranty 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. Maintenance and service

11-34Maintenance and service
Tires and wheels &Types of tires
You should be familiar with type of tires
present on your vehicle. ! All season tires
The factory-installed tires on your new
vehicle except 2.5GT spec.B 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
conditions. However all season tires do
not offer as much traction performance as
winter (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. ! Summer tires
The factory-installed tires on your new
2.5GT spec.B vehicle are 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-
covered 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
replace all four tires. !
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
summer tires and all season tires on roads
other than snow-covered and icy roads.
& Tire pressure monitoring
system (TPMS) (if equipped)
The tire pressure monitoring 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
vehicle 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
pressures higher than those shown on the tire placard. Specifically, inflate them by an
extra 1 psi (6.9 kPa, 0.07 kgf/cm2) for
every difference of 10 8F (5.6 8C) between
the temperature in the garage and the
temperature 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 8F (15.6 8C).
Example:
Tire size: P225/55R17 95V, P225/60R16 97H
Standard tire pressures:
Front: 32 psi (220 kPa, 2.2 kgf/cm

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
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
increase 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
warning 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 snowtires), 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 illuminate
steadily after blinking for approximately
one minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
WARNING
If the low tire pressure warning light
does not come on briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-ble.
If this light comes on while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving Maintenance and service
11-35

11-36Maintenance and service
serious vehicle damage and serious
personal injury could occur.
If this light still comes on while
driving after adjusting the tire pres-
sure, 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 illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
& 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 immedi-
ately if you find any problem.
NOTE . When 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
other rough surfaces. If doing so is
unavoidable, keep the vehicle ’s speed
down to a walking pace or less, and
approach the curbs as squarely as
possible. Also, make sure the tires are
not pressed against the curb when you
park the vehicle.. If you feel unusual vibration while
driving or find it difficult to steer the
vehicle 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 vehicleinspected.
& Tire pressures and wear
Maintaining 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 thevehicle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to

11-38Maintenance 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
magnifies the effects of road-surface
bumps and dips, possibly resulting in
vehicle damage.
WARNING
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
vehicle control could lead to anaccident. &
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 sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not
correctly 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*
causes the tires to wear on one side
and reduces the vehicle ’s running
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.

11-40Maintenance and service
Vehicles equipped with unidirectional tires
1) Front
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 (12,000
km). Move the tires to the positions shown
in the applicable illustration each time they
are rotated.
Replace any damaged or unevenly worn
tire at the time of rotation. After tire
rotation, adjust the tire pressures and
make sure the wheel nuts are correctlytightened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become loose. &
Tire replacement
The wheels and tires are important and
integral parts of your vehicle ’s design;
they cannot be changed arbitrarily. The
tires fitted as standard equipment are
optimally matched to the characteristics
of the vehicle and were selected to give
the best possible combination of running
performance, ride comfort, and service
life. It is essential for every tire to have a
size and construction 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
replace the tires with new ones that are
identical to those fitted as standard equip-ment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.
WARNING
. All 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
different types, sizes or degrees
of wear can result in damage to
the vehicle ’s power train. Use of
different types or sizes of tires
can also dangerously reduce
controllability and braking per-
formance and can lead to anaccident.
. Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously re-
duce controllability, resulting in
an accident.
& Wheel replacement
When 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.

WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to anaccident. 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,
tighten 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
replace them with genuine SUBARU parts
designed for aluminum wheels. Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
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. Maintenance and service
