Maintenance schedule
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”.
Maintenance precautions
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.
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.
. 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 ser-
viced 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 sup-
ported 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
– CONTINUED –
11-4 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,
thecoolingfanmayoperate
suddenly even when the engine
is stopped.
& When you do checking or
servicing in the engine compartment while the engine is
running
WARNING
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, belts and any ot her moving
engine parts. Removing rings,

while the vehicle is moving and
block your view, which may cause
an accident and serious bodily injury.
3. Release the secondary hood release
located under the front grille by moving the
lever toward the left.
4. 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.
3. 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
Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
Maintenance and service 11-9
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly inserted until it stops with the graphic
symbol “
” on its top appearing as
shown in the illustration.
2.5-liter models
1) Notch
2) Upper level
3) Lower level
3.0-liter models
1) Upper level
2) 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.
– CONTINUED –
11-10 Maintenance and service
. 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.
To prevent overfilling the engine oil, do not
add any additional oil above the upper
level when the engine is cold.
In 2.5-liter-engine models, the dipstick has
a notch above the upper 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.
& 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.
2.5-liter models
3.0-liter models
4. Drain out the engine oil by removing
the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
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.
Maintenance and service 11-11
9. Clean the rubber seal seating area of
the bottom of engine and install the oil
filter by hand turning. Be careful not to
twist or damage the seal.
10. Tighten the oil filter by the amount
indicated in the following table after the
seal makes contact with the bottom of
engine.
2.5-liter models

Oil capacity (Guideline):
2.5-liter models: 4.2 US qt (4.0 liters, 3.5
Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8
Imp qt)
The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil and the time the oil is left
flowing out. After 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.
& Recommended grade and
viscosity
CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade:
ILSAC GF-4, which can be identified with
the ILSAC certification mark (Starburst
mark)
or API classification SM with the words
“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)
API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving
capabilities
Maintenance and service 11-13
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 number 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.
& 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
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 add-
ing, 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.
& 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.
& Engine coolant
! Checking the coolant level
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW” level mark, add coolant up to the
“FULL” level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.
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.
Maintenance and service 11-15
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant

coolant to the radiator’s filler neck and to
the reserve tank’s “FULL” level.
10. Put the radiator cap and reservoir cap
back on and tighten firmly.
Air cleaner element
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the a ir
cleaner element is not installed
when the engine backfires, you
could be burned.
CAUTION
When replacing the air cleaner element, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perforated or removed, engine wear will be
excessive and engine life shortened.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the element.
