Climate control/Air filtration system
allow outside air to circulate into the
heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency.
&Lubrication oil circulation in
the refrigerant circuit
Operate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.
&Checking air conditioning
system before summer sea-
son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer.
&Cooling and dehumidifying in
high humidity and low tem-
perature weather conditions
Under 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 loaded
To 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 on a steep
upgrade.
&Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od 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 system
Your vehicle’ s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule found in the
“Warranty and Maintenance Booklet ”. 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.
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.

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
. 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 to
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-
Maintenance and service/Maintenance schedule

erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE
SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.
&Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and apply
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 has stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. When the ignition switch is in the
“ON ”position, the cooling fan
may operate suddenly even
when the engine is stopped. If
your body or clothes come into
contact with a rotating fan, that
could result in serious injury. To
avoid risk of injury, perform the
following precautions.
– Models with push-button start
system:
Always turn the push-button
ignition switch to the “OFF”
position and confirm that the
operation indicator on the
switch is turned off. Then take
the access key out from the
vehicle.
– Models without push-button
start system:
Always remove the key from
the ignition switch.
. Before performing any servicing
on a vehicle equipped with a remote engine start system (a
dealer option), temporarily place
the remote engine start system in
service mode to prevent it from
unexpectedly starting the engine.
&
When checking or servicing
in the engine compartment
CAUTION
. Do not contact the drive belt
cover while checking the compo-
nents in the engine compart-
ment. Doing so may cause your
hand to slip off the cover and
result in an unexpected injury.
. Do not touch the oil filter until the
11-4

engine has cooled down comple-
tely. Doing so may result in a
burn or other injury. Note that the
oil filter becomes very hot when
the engine is running and re-
mains hot for some time after
the engine has stopped.
&When checking or servicing
in the engine compartment
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, drive belt and any other moving
engine parts. Removing rings,
watches and ties is advisable.
Engine hood
CAUTION
. When you open the engine hood,
do not stand the wiper blades up.
Furthermore, while the hood is
open, do not operate the wind-
shield wipers. Doing so could
result in damage to the engine
hood and wiper blades.
. Be extremely careful not to catch
fingers or other objects when
closing the engine hood.
. Do not push the hood forcibly to
close it. It could deform the
metal.
. Be extremely careful opening the
engine hood when the wind is
strong. The engine hood could
close suddenly, possibly causing
injuries from slamming.
. Do not install accessories other
than genuine SUBARU parts to
the engine hood. If the engine
hood becomes too heavy, the
stay may not be able to support
holding it open. To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
position.
2. Pull the hood release knob under the
instrument panel.

3. 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.
The coolant should be 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
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.
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 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.
