Maintenance schedule
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the“Warranty and Main-
tenance Booklet ”.
For details of your maintenance schedule,
read the separate “Warranty and Main-
tenance Booklet ”. Maintenance precautions
When maintenance and service are re-
quired, 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 opera-
tion. 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 per-
formed on a single two-wheel
dynamometer or similar appara-
tus. 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 yourvehicle. .
Always be very careful to avoid
injury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, batteryacid.
. Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
. Always use the proper tools and
make certain that they are wellmaintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
a safety stands to support thevehicle.
. 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
11-3

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 these 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.
& 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. Engine hood
To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their originalpositions.
2. Pull the hood release knob under the
instrument panel.

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. 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.
2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops with the graphic
symbol “
”on its top appearing as
shown in the illustration.

3.0 L models
1) Upper level
2) 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.
NOTE . To prevent overfilling the engine oil,
do not add any additional oil above the
upper level when the engine is cold.. In 2.5 L engine models, the level
gauge 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.
