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
8-4 Driving tips
reduce HC, CO and NOx in exhaust gas-
es, thus providing cleaner exhaust.
To avoid damage to the catalytic convert-
er:
y Use only unleaded gasoline. Even a
small amount of leaded gasoline will dam-
age the catalytic converter.
y Never start the engine by pushing or
pulling the vehicle.
y Avoid racing the engine.
y Never turn off the ignition switch while
the vehicle is moving.
y 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.
y Do not apply undercoating or rust pre-
vention treatment to the heat shield of cat-
alytic converter and the exhaust system. Periodic inspections To keep your vehicle in the best condition
at all times, always have the recommend-
ed maintenance services listed in the
maintenance schedule in the “Warranty
and Maintenance Booklet” performed at
the specified time or mileage intervals.
Driving in fo reign countries When planning to use your vehicle in an-
other country:
y Confirm the availability of the correct fu-
el. (Refer to the “Fuel requirements” sec-
tion in chapter 7.)
y Comply with all regulations and require-
ments of each country.
