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 ” .
NOTE For models with a multi function dis-
play, you can set a reminder to be
displayed when a scheduled mainte-
nance item is almost due. For details,
refer to “ Maintenance settings ” F 3-79.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
model 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 your
vehicle. . 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, battery
acid.
. 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 well
maintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support the
vehicle.
. 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 toMaintenance and service/Maintenance schedule
– CONTINUED –11-3

CAUTION. For models except STI, be careful
not to touch the engine oil filter
when removing the oil filler cap.
Doing so may result in a burn, a
pinched finger, or may cause
some other injury.
. 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.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.
For models STI, 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. NOTE 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 ” .
NOTE . Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also,
used oils are properly disposed of.
. If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.
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. ! Changing the oil filter
It may be difficult to change the oil filter.
Have the oil filter changed by your
SUBARU dealer if necessary.
! Changing the oil
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.

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
It may be difficult to change the coolant.
Have the coolant changed by your
SUBARU dealer if necessary.
The coolant should be changed according
to the maintenance schedule in the
“ Warranty and Maintenance Booklet ” .Air cleaner element WARNINGDo 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.
CAUTIONWhen replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
It is not necessary to clean or wash the air
cleaner element. & 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.

2. Open the air cleaner case and pull the
cover rearward while lifting it up.
3. Remove the air cleaner element. 4. Clean the inside of the air cleaner case
and case cover with a damp cloth and
install a new air cleaner element.
5. To install the air cleaner case cover,
insert the projections on the air cleaner
case cover into the slits on the air cleaner
case. The illustration above shows an
example in which the projections are not
fitted into the slits correctly.
6. Install in the reverse order of removal. Spark plugs 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 ” .
& Recommended spark plugs For the recommended spark plugs, refer
to “ Electrical system ” F 12-8.Maintenance and service/Spark plugs

Maintenance and service/Drive belts
Drive belts NOTE For models except STI, it is unneces-
sary to check the deflection of the drive
belt periodically because this engine is
equipped with an automatic belt ten-
sion adjuster. However, replacement of
the belt should be done according to
the maintenance schedule in the “ War-
ranty and Maintenance Booklet ” . Con-
sult your SUBARU dealer for replace-
ment.
If the drive belt is loose, cracked or
worn, contact your SUBARU dealer. STI

CAUTION
The front side belt, which runs in
conjunction with the following com-
ponents, must be used within the
specified deflection.
. Power steering oil pump pulley
. Alternator pulley
. Crank pulley
Check the deflection of the front side belt and if there is any loosen-
ess, cracks, wear or unusual noise
on the front side belt, contact your
SUBARU dealer.
Continuing to use the vehicle with
the belt outside of the specification
may cause the engine to malfunc-
tion and the above components to
malfunction.
To check the deflection of the front side
belt, place a straightedge (ruler) across
two adjacent pulleys (alternator pulley and
crank pulley) and apply a force of 22 lbf
(98 N, 10 kgf) midway between the pulleys
by using a spring scale. The belt deflec-
tion should be the amount specified. If the
front side belt is loose, cracked or worn,
contact your SUBARU dealer. in (mm)

SUBARU dealer.11-22

Manual transmission oil It is not necessary to check the transmis-
sion oil level. Check that there are no
