Temperature sensors
1) Solar sensor
2) Interior air temperature sensor
The automatic climate control system em-
ploys several sensors. These sensors are
delicate. If they are treated incorrectly and
become damaged, the system may not be
able to control the interior temperature
correctly. To avoid damaging the sensors,
observe the following precautions:
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows:
– Solar sensor: beside windshield de-
froster grille
– Interior air temperature sensor: on the side of the driver-si
de part of the center
panel
– Outside temperature sensor: behind
front grille.
Continued operation in the “ ”
position may fog up the windows.
Switch to the “ ” position as
soon as the outside dusty condition
clears.

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.

Air filtration system (if
equipped)
If your vehicle’s air conditioning system is
equipped with an air filtration system, re-
place the filter element according to the
replacement schedule shown in the fol-
lowing. This schedule should be followed
to maintain the filter’s dust collection abili-
ty. Under extremely dusty conditions, the
filter should be replaced more frequently.
Have your filter checked or replaced by
your SUBARU dealer. For replacement,
we recommend the use of a genuine
SUBARU air filter kit.
Replacement schedule:
Every 12 months or 9,300 miles (15,000
km) whichever comes first
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
Contact your SUBARU dealer if the
following occurs, even if it is not yet time to change the filter:
– Reduction of the air flow through the vents.
– Windshield gets easily fogged or misted.
