11-4Maintenance 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 seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner 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 pre-
vent 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.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option) temporarily place
that system in the service mode
to prevent it from unexpectedly
starting the engine. &
When you do checking or
servicing in the engine com-
partment 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 other moving
engine parts. Removing rings,
watches and ties is advisable.

11-8Maintenance and service
Engine oil NOTE .The engine oil consumption rate is
not stabilized, and therefore cannot be
determined until the vehicle has tra-
veled at least several thousand miles
(kilometers). Even after break-in, when
the vehicle is used under severe driv-
ing conditions such as those men-
tionedintheWarrantyandMainte-
nance Booklet, engine oil is consumed
or deteriorated more quickly than un-
der 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 fre-
quently. Please refer to the Warranty
and Maintenance Booklet for more de-tails.. 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, contact your SUBARU deal-
er. &
Checking the oil level
Check the engine oil level at each fuelstop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the level gauge that has the “” symbol on top, wipe it clean, and
insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
1) Notch
2) Upper level
3) Lower level
4. Pull out the level gauge 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 vis-
cosity.
. 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. & Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “War-
ranty 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.
Turbo models
Non-turbo 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.
6. Remove the under cover.

7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal.
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. Oil filter color Part number
Amount of
rotation
Black 15208AA100 1 rotation
Blue 15208AA12A 7/8
rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover.
12. Pour engine oil through the filler neck. Oil capacity (guideline): 4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only 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 level gauge 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 engineoil.
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.

&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.
API Service label
1) Indicates the oil quality by API designa- tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities
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 tempera- ture
*: 5W-30 is recommended.
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 recom-
mended grade and viscosity. Maintenance and service

11-12Maintenance and service
&Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or is
used for heavy-duty applications, 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 radia-
tor 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 boil-
ing hot coolant when the cap isremoved.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top up the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is shortened to that of the mixingcoolant.
. 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 con- nections
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 coolant temperature high
warning light blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warninglight ”F 3-13.
Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
Refer to “Fuses ”F 11-44 and “Fuse panel
located in the engine compartment ”F 12-
8.
If frequent addition of coolant is neces-
sary, 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
1) “FULL ”level mark
2) “LOW ”level mark
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.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface. !
Changing the coolant
WARNING
Never attempt to remove the radia-
tor 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 boil-
ing hot coolant when the cap isremoved.
Always add genuine SUBARU cooling
system conditioner whenever the coolant
is replaced.
Change the engine coolant and add
genuine SUBARU cooling system condi-
tioner using the following procedures
according to the maintenance schedule.
1. Remove the under cover. Maintenance and service
