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 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 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 steepupgrade. & 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 shown in the
following table. This schedule should be
followed to maintain the filter ’sdust
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.
Replacement schedule: Every 15 months or 15,000 miles (24,000 
km) whichever comes first
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. Climate control

8-4Driving tips
To avoid damage to the catalytic conver- ter: .Use only unleaded gasoline. Even a
small amount of leaded gasoline will 
damage the catalytic converter. . Never start the engine by pushing or
pulling the vehicle.. Avoid racing the engine.
. Never turn off the ignition switch while
the vehicle is moving.. Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back- 
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer. . Do not apply undercoating or rust
prevention treatment to the heat shield of 
catalytic converter and the exhaust sys-tem. . Do not drive with an extremely low fuel
level. Periodic inspections 
To keep your vehicle in the best condition 
at all times, always have the recom-
mended maintenance services listed in
the maintenance schedule in the
“War-
ranty and Maintenance Booklet ”per-
formed at the specified time or mileageintervals. Driving in foreign countries 
When planning to use your vehicle in 
another country: .
Confirm the availability of the correct
fuel. Refer to “Fuel requirements ”F 7-2.
. Comply with all regulations and re-
quirements of each country.
