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.
In the case of OUTBACK models,
lower the hood to a height of approxi-
mately 5.9 in (15 cm) above its closed
position and then let it drop.
In the case of the models except OUT- BACK, lower the hood to a height of
approximately 12 in (30 cm) above its
closed position and then 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.
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 in-
jury. Maintenance 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, we recommend that you
contact your SUBARU dealer. &
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 dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly in-
serted 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 Maintenance and service

11-10Maintenance and service
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 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.
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 “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.

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 ofengine.

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 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):
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 tempera-
ture 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 engineoil. &
Recommended grade and viscosity
CAUTION
Use only engine oil with the recom-
mended 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.

11-18Maintenance and service
& Replacing the air cleaner element
Replace the air cleaner element according
to the maintenance schedule in the“ Warranty and Maintenance Booklet ”. Un-
der extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. ! Non-turbo models

bottom of the side surface of the air
cleaner case. 3. Undo the screw and pull the air duct
out of the air cleaner case.
4. Unsnap the two clamps holding the air
cleaner case cover.
5. Open the air cleaner case cover and
remove the air cleaner element.
6. Clean the inside of the air cleaner
cover and case with a damp cloth and

CAUTION
. When disconnecting the spark
plug cables, always grasp the
spark plug cap, not the cables.
. Make sure the cables are re-
placed in the correct order.
It may be difficult to replace the spark
plugs. It is recommended that you have
the spark plugs replaced by your
SUBARU dealer.
The spark plugs should be replaced
according to the maintenance schedule
in the “Warranty and Maintenance Book-
let ”. &
