blinded. For this reason, use care not to cover the
sensors with stickers, or other similar items. Periodi-
cally wipe the sensors clean using a piece of dry
soft cotton cloth or an applicator.
n Compass calibration
1. For optimum calibration, switch off all nonessen-
tial electrical accessories (rear window defogger,
heater/air conditioning system, spotlight, etc.) and
ensure all doors are shut.
2. Drive to an open, level area away from large me-
tallic objects or structures and make certain the igni-
tion switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then
release, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears
from the display (about two or three circles).
5. The compass is now calibrated. Further calibra-
tion is not required. The compass will automatically
calibrate from this point forward. n

Compass calibration zones
1. The zone setting is factory preset to Zone 8. Re- fer to the “Compass calibration zone ” map shown
above or one attached to the end of this manual to
verify that the compass zone setting is correct for your geographical location.
2. Press and hold the right button for 3 seconds
then release, and the word “ZONE” will briefly ap-
pear and then the zone number will be displayed.
3. Press the right hand button repeatedly to cycle
the display through all possible zone settings. Stop
cycling when the correct zone setting for your loca-
tion is displayed.

Operating tips for heater and air conditioner Cleaning ventilator grille
HG4016BA
Always keep the front ventilator inlet grille free of
snow, leaves, or other obstructions to ensure effi-
cient 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 win- dows open for a few minutes to allow outside air to
circulate into the heated interior. This results in
quicker cooling by the air conditioner. Keep the win-dows closed during the operation of the air condi-
tioner for maximum cooling efficiency. Lubrication oil circulation in the refrigerant circuit
Operate the air conditioner compressor at a low en- gine speed (at idle or low driving speeds) a few
minutes each month during the off-season to circu-
late its oil. Checking air conditioning system before summer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and proper operation each spring.
This check is best performed by your SUBARU
dealer.

Cooling and dehumidifying in high humidity and low temperatureweather condition
Under certain weather conditions (high relative hu-
midity, low temperatures, etc.) a small amount of wa-
ter vapor emission from the air outlets may be not-
iced. 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 conditioner operation whenever
the accelerator is fully depressed such as duringrapid acceleration or when driving on a steepupgrade. Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method of adding, chang-
ing 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 (if equipped) If your vehicle’s air conditioning system is equipped
with an air filtration system, replace the filter element
according to the replacement schedule shown
below. This schedule should be followed to maintain the filter ’s dust collection ability. Under extremely
dusty conditions, the filter should be replaced more
frequently. Since the filter element is a viscous type,
it is unnecessary to clean or wash the element.
Have your filter checked or replaced by your
SUBARU dealer.
Replacement schedule: Every 12 months or 7,500 miles (12,000 km) whichever comes first
NOTE The filter can influence the air conditioning, heat- ing and defroster performance.
