Maintenance precautions
The scheduled maintenance items required to be serviced at regular intervals are shown in the “Warranty
and Maintenance Booklet”.
For details of your maintenance schedule, read the
separate “Warranty and Maintenance Booklet”.
When maintenance and service are required, 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 operation. Any problems caused by
improper maintenance and service performed by you
are not eligible for warranty coverage.
y Testing of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel dynamometer or similar apparatus. Attempting to
do so will result in transmission damage and in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.
y Always select a safe area when performing
maintenance on your vehicle.
y Always be very careful to avoid injury when
working on the vehicle. Remember that some of
– CONTINUED –

Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, battery acid.
y Your vehicle should only be serviced by persons fully competent to do so. Serious personal injury may result to persons not experienced
in servicing vehicles.
y Always use the proper tools and make certain
that they are well maintained.
y Never get under the vehicle supported only
by a jack. Always use a safety stands to support the vehicle.
y Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas.
y Do not smoke or allow open flames around
the fuel or battery. This will cause a fire.
y Because the fuel system is under pressure,
replacement of the fuel filter should be performed only by your SUBARU dealer.
y Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water.
y Do not tamper with the wiring of the SRS airbag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that
may activate the system or it can render it inoperative. The wiring and connectors of these
systems are yellow for easy identification. NEVER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
Before checking or servicing in the en-
gine compartment
y Always stop the engine and set the parking
brake firmly to prevent the vehicle from moving.
y Always let the engine cool down. Engine
parts become very hot when the engine is running and remain hot for some time after the engine is stopped.
y Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine components. This may cause a fire.
y Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly
11-4

even when the engine is stopped.
When you do checking or servicing in
the engine compartment while the engine is running
A running engine can be dangerous. Keep your
fingers, hands, clothing, hair and tools away
from the cooling fan, belts and any other moving engine parts. Removing rings, watches and
ties is advisable.

up to the upper level.
y Use only engine oil with the recommended
grade and viscosity.
y Be careful not to spill engine oil when adding
it. If oil touches the exhaust pipe, it may cause
a bad smell, smoke, and/or a fire.
If you check the oil level just after stopping the engine,
wait a few minutes for the oil to drain back into the oil
pan before checking the level.
Just after driving or while the engine is warm, the engine oil level reading may be in a range between the
upper level and the notch mark. This is caused by thermal expansion of the engine oil.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is
cold.
Changing the oil and oil filter
Change the oil and oil filter according to the maintenance schedule in the “Warranty and Maintenance
Booklet”.
The engine oil and oil filter must be changed more frequently than listed in the maintenance schedule when
driving on dusty roads, when short trips are frequently
made, or when driving in extremely cold whether.
1. Warm up the engine by letting the engine idle for
about 10 minutes to ease draining the engine oil.
2. Park the vehicle on a level surface and stop the engine.

If the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applications such as towing a trailer, use of oil with the following grade and viscosities is recommended.
API classification SL (or SJ):
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
Synthetic oil
You can use synthetic engine oil that meets the same
requirements given for conventional engine oil. When
using synthetic oil, you must use oil of the same classification, viscosity and grade shown in this owner’s
manual, and must follow the oil and filter changing intervals shown in the maintenance schedule.
Cooling system
Never attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is removed.
y The cooling system has been filled at the factory with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
against freezing down to –33°F (–36°C). For
adding, use genuine SUBARU coolant or an
equivalent: a mixture of 50% soft water and 50%
ethylene-glycol basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix different kinds of coolant.
y Do not splash the engine coolant over paint-

ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
Cooling fan, hose and connections
Your vehicle employs an electric cooling fan which is
thermostatically controlled to operate when the engine
coolant reaches a specific temperature.
If the radiator cooling fan does not operate even when
the engine coolant temperature gauge exceeds the
normal operating range, the cooling fan circuit may be
defective. Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling system
checked by your SUBARU dealer.
If frequent addition of coolant is necessary, there may
be a leak in the engine cooling system. It is recommended that the cooling system and connections be
checked for leaks, damage, or looseness.

Automatic transmission fluid
Checking the fluid level
The automatic transmission fluid expands largely as
its temperature rises; the fluid level differs according to
fluid temperature. Therefore, there are two different
scales for checking the level of hot fluid and cold fluid
on the dipstick.
Though the fluid level can be checked without warming up the fluid on the “COLD” range, we recommend
checking the fluid level when the fluid is at operating
temperature.
T Checking the fluid level when the fluid is hot
1. Drive the vehicle several miles to raise the temperature of the transmission fluid up to normal operating
temperature; 158 to 176°F (70 to 80°C) is normal.
2. Park the vehicle on a level surface and set the parking brake.
3. First shift the selector lever in each position. Then
shift it in the “P” position, and run the engine at idling
speed.

Replacement of brake pad and lining
HS7012BA
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.
Maintenance and service
If you continue to drive despite the scraping
noise from the audible brake pad wear indicator, it will result in the need for costly brake rotor repair or replacement.
Breaking-in of new brake pads and lin-
ings
When replacing the brake pad or lining, use only genuine SUBARU parts. After replacement, the new parts
must be broken in as follows:

Tires and wheels
Types of tires
You should be familiar with type of tires present on
your vehicle.
The factory-fitted 17-inch tires on the WRX-STi are
summer tires. The factory-fitted tires on other versions
are all-season tires. The 17-inch tires that can be dealer-fitted on the WRX as an option are summer tires.
T 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.
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-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.
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 summer tires and all season tires on
roads other than snow-covered and icy roads.
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 immediately if you find
any problem.
NOTE
y When the wheels and tires strike curbs or are
subjected to harsh treatment 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
– CONTINUED –

Maintenance and service
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 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 vehicle inspected.
Tire pressures and wear
Maintaining the correct tire pressures helps to maximize the tires’ service lives and is essential for good
running performance. 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.
UGB510BA
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 vehicle.
When a tire becomes warm, the air inside it expands,
causing the tire pressure to increase. Be careful not to
mistakenly release air from a warm tire to reduce its
pressure.
11-48
Page 49
Maintenance and service
NOTE
y The air pressure in a tire increases by approximately 4.3 psi (30 kPa, 0.3 kgf/cm
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).
Do not let air out of warm tires to adjust pressure. Doing so will result in low tire pressure.
Incorrect tire pressures detract from controllability and
ride comfort, and they cause the tires to wear abnormally.

match current loading conditions.
Driving at high speeds with excessively low tire

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 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.
Wear indicators
A
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 replaced when the tread wear indicator appears as a
solid band across the tread.
B

HSB055BB
– CONTINUED –
11-51
Page 52
Maintenance and service
When a tire’s tread wear indicator becomes visible, the tire is worn beyond 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 resulting loss of vehicle control can lead to
an accident.
NOTE
For safety, inspect tire tread regularly and replace
the tires before their tread wear indicators become
visible.
Tire rotation
HSB056BA
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 rotation, adjust the tire pressures and make sure the wheel nuts are correctly
tightened.
11-52
Page 53
Maintenance and service
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 incorrect body-to-tire clearances and inappropriately changes the vehicle’s ground clearance.
All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, and size. You
are advised to replace the tires with new ones that are
identical to those fitted as standard equipment.
For safe vehicle operation, SUBARU recommends re-
placing all four tires at the same time.
y All four tires must be the same in terms of
manufacturer, brand (tread pattern), construction, degree of wear, speed symbol, load index
and size. Mixing tires of different types, sizes or
degrees of wear can result in damage to vehicle’s power train. Use of different types or sizes
of tires can also dangerously reduce controllability and braking performance and can lead to
an accident.
y Use only radial tires. Do not use radial tires
together with belted bias tires and/or bias-ply
tires. Doing so can dangerously reduce 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 equipment. Replacement wheels are available from
SUBARU dealers.

Aluminum wheels
Use only those wheels that are specified for

loss of vehicle control could lead to an accident.
NOTE
When any of the wheels is removed and replaced
for tire rotation or to change a flat tire, 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.

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.

Replacement of wiper blades
Grease, wax, insects, or other material on the windshield or the wiper blade results in jerky wiper operation and streaking on the glass. If you cannot remove
the streaks after operating the windshield washer or if
the wiper operation is jerky, clean the outer surface of
the windshield (or rear window) and the wiper blades
using a sponge or soft cloth with a neutral detergent or
mild-abrasive cleaner. After cleaning, rinse the windshield and wiper blades with clean water. The windshield is clean if beads do not form when you rinse the
windshield with water.
Do not clean the wiper blades with gasoline or
a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiper
blades.
If you cannot eliminate the streaking even after following this method, replace the wiper blades using the following procedures:

Battery
y Before beginning work on or near any battery, be sure to extinguish all cigarettes, matches, 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 battery.
y Do not let battery fluid contact eyes, skin,
fabrics, or paint because battery fluid is a corrosive acid. If battery fluid gets on your skin or
in your eyes, immediately flush the area with
water thoroughly. Seek medical help immediately 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 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 because 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, chemicals 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.

Fuses
Never replace a fuse with one having a higher
rating or with material other than a fuse because serious damage or a fire could result.
The fuses are designed to melt during an overload to
prevent damage to the wiring harness and electrical
equipment. The fuses are located in two fuse boxes.

The main fuses are designed to melt during 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 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 vehicle. Such accessories may cause the electronic system to malfunction if they are incorrectly installed or if
they are not suited for the vehicle.

Headlights (U.S.-spec. WRX-STi)
High-intensity-discharge (HID) bulbs are used
for the low beams of the headlights on the U.S.spec. 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 replace them. Neither
should you attempt to replace the high-beam
bulbs, remove/refit the headlight assemblies,
or remove any headlight-assembly components. For replacement of the headlight bulbs
(low-beam and high-beam), removal and installation of the headlight assemblies, and removal
of headlight-assembly components, contact
your SUBARU dealer.

Headlights (Except U.S.-spec. WRX-
STi)
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 develop 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.
NOTE
y If headlight aiming is required, consult your
SUBARU dealer for proper adjustment of the headlight aim.
y It may be difficult to replace the bulbs. Have
your SUBARU dealer replace the bulbs if necessary.
