&Cooling and dehumidifying in
high humidity and low tem-
perature weather conditionsUnder certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate
any problem with the air conditioning
system.&Air conditioner compressor
shut-off when engine is
heavily loadedTo improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving up a steep
incline.
&Refrigerant for your climate
control system1) Air conditioner labelYour air conditioner uses ozone friendly
refrigerant HFC134a (as shown on the air
conditioner label). Therefore, the method
of adding, changing or checking the
refrigerant is different from the method
for CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are not
covered under warranty.
Air filtration systemYour vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the cabin air filter element ac-
cording to the replacement schedule found
in the“Warranty and Maintenance Book-
let”. This schedule should be followed to
maintain the filter’s dust collection ability.
Under extremely dusty conditions, the filter
should be replaced more frequently. Have
your filter checked or replaced by your
SUBARU dealer. For replacement, use
only a genuine SUBARU air filter kit.
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter:
.Reduction of the airflow through
the vents.
.Windshield gets easily fogged or
misted.NOTEThe filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.

Maintenance scheduleU.S. models
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the“Warranty and Mainte-
nance Booklet”. For details, read the
separate“Warranty and Maintenance
Booklet”.
Canada models
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the“Warranty and Service
Booklet”. For details, read the separate
“Warranty and Service Booklet”.
Other models
Some items of your vehicle are required to
be serviced at scheduled intervals. For
details about your maintenance schedule,
read the separate“Warranty and Main-
tenance Booklet”.NOTEYou can set a reminder to be displayed
when a scheduled maintenance item is
almost due. For details, refer to“Main-
tenance settings”F3-59.
Maintenance precautionsWhen 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 sec-
tion 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 performed
on a single two-wheel dynam-
ometer or similar apparatus. At-
tempting to do so will result in
transmission damage and in un-
controlled 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 avoidinjury 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 to
guard against getting oil or fluids

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.
NOTETo 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 filterChange 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 ex-
tremely cold weather.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.
&Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to“Engine oil”F12-4.NOTEEngine 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 en-
gine.

Except STI
1) Fill up to this level3. After refilling the reserve tank and the
radiator, reinstall the cap 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
It may be difficult to change the coolant.
Have the coolant changed by your
SUBARU dealer if necessary.
Have the coolant changed according to the
maintenance schedule in the“Warranty
and Maintenance Booklet”.
Air cleaner element
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters in-
take 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.
CAUTION
When 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 perforated or
removed, engine wear will be excessive
and engine life shortened.
It is not necessary to clean or wash the air
cleaner element.
