Maintenance schedule
Maintenance and service
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.
y Testing of an All-Wheel Drive ve-
hicle 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 in-
jury 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.
y 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.
y Always use the proper tools and
make certain that they are well
maintained.
y Never get under the vehicle sup-
ported 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.
– CONTINUED –
11-4 Maintenance and service
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 engine 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
even when the engine is stopped.
When you do checking or ser-
vicing 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.
Engine hood
B00300
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
instrument panel.
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.
Maintenance and service 11-5
B00301
3. Release the secondary hood release
located under the front grille by moving
the lever toward the left.
4. Lift up the hood.
To close the hood:
1. Lower the hood to a point approximately 20 in (50 cm) from the closed position
and then give the hood a strong push
down to make it drop.
2. 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.
When closing the hood, be careful
not to pinch your or other person’s
hands or anything else in the hood.

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.
B00303
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.

B00304
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.
y Use only engine oil with the rec-
ommended 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 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.
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 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.

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 indi-
cated in the following table after the seal
makes contact with the bottom of engine.
B00305 B00306
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.
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. Open the access cover by removing
the five clips and turning the access cover
counterclockwise. The oil filter will be exposed.

y Never over tighten the oil filter be-
cause that can result in an oil leak.
y Thoroughly wipe off any engine
oil that has spilled over the exhaust pipe and/or under-cover. If
left unremoved, the oil could
catch fire.
11.Reinstall the cover under the oil filter.
12.Pour engine oil through the filler neck.
Oil capacity (Guideline):
5.8 US qt (5.5 liters, 4.8 Imp qt)
Maintenance and service 11-9
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
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.

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
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, yeararound 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.
Maintenance and service 11-11
y 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
T Checking the coolant level
B00309
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.
B00018
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.
y Be careful not to spill engine cool-
ant 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.
y Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

11-12 Maintenance and service
T Changing the coolant
Always add genuine Subaru cooling system conditioner whenever the coolant is
replaced.
Change the engine coolant and add genuine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule in the “Warranty and Maintenance Booklet”.
1. Remove the under cover.
B00310
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
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.
4. Install the under cover.

B00311
1) Fill up to here
5. Slowly pour the coolant and fill up to
just below the filler neck, allowing enough
room to add genuine Subaru cooling system conditioner in the radiator. Add genuine Subaru cooling system conditioner until the coolant level reaches the filler neck.
Do not pour the coolant too quickly, as this
may lead to insufficient air bleeding and
trapped air in the system.
Coolant capacity (Guideline):
7.8 US qt (7.4 liters, 6.5 Imp qt)
y Be careful not to spill engine cool-
ant 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.
y Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

6. Pour the coolant and fill to the reservoir
tank’s “FULL” level mark.
B00018
7. Put the radiator cap back on and tighten firmly. At this time, make sure that the
rubber gasket in the radiator cap is cor-
rectly in place.
8. Start and run the engine for more than
five minutes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the coolant cools down (122 to 140°F [50 to
60°C]). If there is any loss of coolant, add
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
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 air cleaner
element is not installed when the engine backfires, you could be burned.
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.
Replacing the air cleaner ele-
ment
Replace the air cleaner element according
to the maintenance schedule in the “Warranty and Maintenance Booklet”. Under
extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts.
