Operating tips for heater and
air conditioner „ Cleaning ventilator grille
Always keep the front ventilator inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept
clean because cooling performance is im-
paired by any accumulation of insects and
leaves on the condenser.
„ Efficient cooling after parking
in direct sunlight
After parking in direct sunlight, drive with
the windows open for a few minutes to al- low 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 con-
ditioner 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 op-
eration each spring. Have your SUBARU
dealer perform this check.
„ Cooling and dehumidifying in
high humidity and low tem-
perature weather condition 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 sys-
tem.
„ Air conditioner compressor
shut-off when engine is
heavily loaded To improve acceleration and gas mileage,
the air conditioner compressor is de-
signed to temporarily shut off during air
conditioner operation whenever the accel-
erator 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
method of adding, changing or checking
the refrigerant is diffe rent 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.400590

„ Before checking or servicing

vicing in the engine compart-
ment while the engine is run-
ning Engine hood
To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
positions.
2. Pull the hood release knob under the
instrument panel.y 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.
y Do not tamper wi th the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. The wir-
ing and connectors of these sys-
tems are yellow for easy identifi-
cation. NEVER use a circuit tester
for these wiring.
If your SRS airbag or seatbelt pre-
tensioner needs service, consult
your nearest SUBARU dealer.
y Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving. y Always let the engine cool down.
Engine parts b ecome very hot
when the engine is running and
remain hot for some time after the
engine is stopped.
y Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
y Always remove the key from the
ignition switch. When the ignition
switch is in the “ON” position, the
cooling fan may operate suddenly
even when the engine is stopped.
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, belts and any other moving en-
gine parts. Removing rings, watch-
es and ties is advisable. B00099

– CONTINUED –Engine oil „ Checking the oil levelCheck the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic symbol
“ ” on its top appearing as shown in
the illustration. 2.5-liter models

level, add oil to bring the level up to the up-
per level.B00104 1

y Use only engine oil with the rec-
ommended grade and viscosity.
y 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 en-
gine oil gets on the exhaust pipe,
be sure to wipe it off. 1

11 - 1 0 Maintenance and service
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.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
In 2.5-liter-engine models, the dipstick 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 filterChange the oil and oil filter according to
the maintenance schedule in the “Warran-
ty 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 frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine 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-liter models
3.0-liter 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.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it se-
curely with a new sealing washer after the
oil has completely drained out.

11 - 2 0 Maintenance and service
Drive belts The alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct.
„ 2.5-liter models
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley in (mm)
To check belt tensi on, place a straight-
edge (ruler) across two adjacent pulleys
and apply a force of 22 lbs (98 N, 10 kg)
midway between the pulleys by using a
spring scale. Belt deflection should be the
amount specified.
„ 3.0-liter models It is unnecessary to check belt tension pe-
riodically because your engine is
equipped with an autom atic belt tension
adjuster. However, replacement of the
belt should be done according to the
maintenance schedule in the “Warranty
and Maintenance Booklet”. Consult your
SUBARU dealer for replacement.
If a belt is loose, cr acked, or worn, contact
your SUBARU dealer. Manual transmission oil „ Checking the oil level

Power steering fluid „ Checking the fluid level The power steering fluid expands greatly
as its temperature rises; the fluid level dif-
fers according to fluid temperature. There-
fore, the reservoir tank has two different
checking ranges for hot and cold fluids.
Check the power steering fluid level
monthly.
1. Park the vehicle on a level surface, and
stop the engine.
2. Check the fluid level of the reservoir
tank.
When the fluid is hot after the vehicle has
been run: Check that the oil level is be-
tween “HOT MIN” and “HOT MAX” on the
surface of the reservoir tank.
When the fluid is cool before the vehicle is
run: Check that the oil level is between
“COLD MIN” and “COLD MAX” on the sur-
face of the reservoir tank.
3. If the fluid level is lower than the appli-
cable “MIN” line, add the recommended
fluid as necessary to bring the level be-
tween the “MIN” and “MAX” line. If the fluid level is extreme low, it may indi-
cate possible leakage. Consult your
SUBARU dealer for inspection.
