Temperature sensors
1) Solar sensor
2) Interior air temperature sensor
The automatic climate control system
employs several sensors. These sensors
are delicate. If they are treated incorrectly
and become damaged, the system may
not be able to control the interior tempera-
ture correctly. To avoid damaging the
sensors, observe the following precau-tions: – 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
defroster grille Climate control
4-11

4-12Climate control
–Interior air temperature sensor: on the
side of the driver-side part of the center panel – Outside temperature sensor: behind
front grille. 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 impaired
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
allow 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 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 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 conditioningsystem.
