Maintenance and service

Maintenance schedule

Maintenance precautions

The scheduled maintenance items required to be serviced at regular intervals
are shown in the “Warranty and Maintenance Booklet”.

When maintenance and service are required, it is recommended that all work be
done by an authorized SUBARU dealer.

For details of your maintenance schedule,
read the separate “Warranty and Maintenance Booklet”.

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.

WARNING
. 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.
. Always select a safe area when
performing maintenance on your
vehicle.

11-3

. Always be very careful to avoid
injury when working on the vehicle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, battery
acid.
. 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.
. Always use the proper tools and
make certain that they are well
maintained.
. Never get under the vehicle supported only by a jack. Always use
a safety stands to support the
vehicle.
. 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

guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. 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 engine compartment
WARNING
. Always stop the engine and set
the parking brake firmly to prevent the vehicle from moving.
. 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.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. Always remove the key from the
ignition switch. When the ignition
switch is in the “ON” position,
the cooling fan may operate
suddenly even when the engine
is stopped.

& When you do checking or
servicing in the engine compartment while the engine is
running
WARNING

Engine hood

To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
positions.
2. Pull the hood release knob under the

WARNING
Always check that the hood is
properly locked before you start
driving. If it is not, it might fly open
while the vehicle is moving and
block your view, which may cause
an accident and serious bodily injury.

3. Release the secondary hood release
by moving the lever between the front
grille and the hood toward the left.

Lift up the hood, release the hood prop
from its retainer and put the end of the
hood prop into the slot in the hood.
To close the hood:
1. Lift the hood slightly and remove the
hood prop from the slot in the hood and
return the prop to its retainer.
2. Lower the hood until it approaches
approximately 12 in (30 cm) from the
closed position and let it drop.

After closing the hood, be sure the hood is
securely locked.
If this does not close the hood, release it
from a slightly higher position. Do not push
the hood forcibly to close it. It could
deform the metal.

Engine oil

& Checking the oil level

NOTE

Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.

. The engine oil consumption rate is
not stabilized, and therefore cannot be
determined until the vehicle has traveled at least several thousand miles
(kilometers). Even after break-in, when
the vehicle is used under severe driving conditions such as those mentioned in the Warranty and Maintenance Booklet, engine oil is consumed
or deteriorated more quickly than under normal driving conditions. If you
drive your vehicle under these severe
conditions, you should check the oil
level at least at every second fuel fill-up
time, and change the oil more frequently. Please refer to the Warranty
and Maintenance Booklet for more details.
. If the oil consumption rate seems
abnormally high after the break-in
period, for example more than 1 quart
per 1,200 miles or 1 liter per 2,000
kilometers, we recommend that you
contact your SUBARU dealer.

Lower level

4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the
upper level.

CAUTION
. Use only engine oil with the
recommended grade and viscosity.
. 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
engine oil gets on the exhaust

pipe, be sure to wipe it off.
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.

11-9

WARNING
Be careful not to burn yourself with
hot engine oil.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it
securely with a new sealing washer after
the oil has completely drained out.
6. Remove the under cover.
Turbo models

& 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 weather.
1. Warm up the engine by letting the
engine idle for approximately 10 minutes
to ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.

refilling the engine with oil, therefore, you
must use the dipstick to confirm that the
level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal and drain plug.
14. Run the engine until it reaches the
normal operating temperature. Then stop
the engine and wait a few minutes to allow
the oil drain back. Check the oil level
again and if necessary, add more engine
oil.

CAUTION
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.

Oil capacity (guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)

“ENERGY CONSERVING”

These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
ILSAC Certification Mark (Starburst Mark)

In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following
table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be
used together as long as they are the
same API classification and SAE viscosity
as those recommended by SUBARU.

SAE viscosity No. and applicable temperature
*: 5W-30 is preferred.

Engine oil viscosity (thickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine.

CAUTION
Use only engine oil with the recommended grade and viscosity.

& Recommended grade and
viscosity under severe driving conditions
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 SM (or SL):
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
WARNING
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.

CAUTION
. 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 −338F (−368C). For adding, use genuine SUBARU coolant or an equivalent: a mixture of
50% soft water (or clear and
drinkable water) and 50% phosphate or non-amine type 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.
. Do not splash the engine coolant
over painted 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.

3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.

CAUTION
. Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
. Do not splash the engine coolant

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

& Types of tires

use of winter (snow) tires.
When installing winter tires, be sure to
replace all four 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 factoryfitted tires on other versions are all-season
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.

Tires and wheels

! 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
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 snowcovered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the

& 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
. 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
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 vehicle
inspected.

. The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm2) when the tire becomes warm.
. 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).

WARNING

& 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.

11-31

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.

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.

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.

fuel consumption is also lower.

Rolling resistance is high, so fuel consumption is also higher.

Ride comfort is poor. Also, the tire

& Wear indicators

& 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*

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

WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper operation and may cause the tires to rub
against the wheel well housing during turns. The resulting loss of
vehicle control could lead to an
accident.

NOTE
When any of the wheels are 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

The tank is located on the right-hand side
of the trunk.
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).

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
freezes. A larger amount of water could
break the tank if it froze.

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.

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.

CAUTION
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:

a bulb of different wattage could
result in a fire.

& Headlights (WRX-STI)
WARNING
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
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.
