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.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system tem-
porarily place that system in the
service mode to prevent it from
unexpectedly starting the engine. &
When checking or servicing
in the engine compartment
(2.5 L non-turbo models)
CAUTION
Do not contact the belt cover while
checking the components in the
engine compartment. Doing so may
cause your hand to slip off the belt
cover and result in an unexpected
injury.

11-12Maintenance and service
Engine oil
NOTE .When the engine low oil level warn-
ing light illuminates, have your vehicle
inspected by your SUBARU dealer as
soon as possible.. 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.

2.5 L models
1) Notch
2) Full level
3) Low level3.6 L models
1) Full level
2) Low 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. Maintenance and service

11-14Maintenance and service
&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.
2.5 L non-turbo models
2.5 L turbo models
3.6 L 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 and around
the drain plug with a clean cloth and
tighten it securely with a new sealing
washer after the oil has completely
drained out.

3.6 L models
6. Remove the oil filter with an oil filter wrench.
7. Before installing a new oil filter, apply a
thin coat of engine oil to the seal. 8. 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.
9. Tighten the oil filter by the amount
indicated in the following table after the
seal makes contact with the bottom ofengine.

2.5 L models Black 15208AA100 1 rotation

3.6 L models Black 15208AA031 3/4
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 left unremoved, the oil could
catch fire.
10. Reinstall the cover under the oil filter.
11. Pour engine oil through the filler neck. Oil capacity (guideline):
2.5 L models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.6 L models: 6.7 US qt (6.3 liters, 5.5 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 level
gauge to confirm that the level is correct.
12. Start the engine and make sure that no
oil leaks appear around the filter ’s rubber
seal and drain plug.
13. Keep the engine idling until the engine
reaches the normal operating temperature
range, as indicated by the temperature
gauge on the combination meter. After
that, check the engine oil level again. For
further details about the check procedure,
refer to “Checking the oil level ”F 11-12.

&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 (Star-
burst 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 designa- tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities 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 numb
er 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.
