Automatic climate control system (if equipped) NOTE Operate the automatic climate control system when the engine is
running. When the engine coolant is cold, for instance in cold weather, the
air flows through the windshield defroster outlets and the blowerruns at the lowest speed to prevent cold air from blowing directly
against the driver and front passenger. In the “AUTO” mode, if the air temperature in the passenger
compartment is cooled down to the specified temperature, the air
conditioner compressor stops automatically. For efficient defogging
or dehumidifying in cold weather, press the “A/C” switch on.
Even when cooling is not necessary, setting the temperature
much lower than the current outlet air temperature turns on the airconditioner compressor automatically and the “A/C” indicator light
on the control panel comes on.
The automatic climate control system automatically controls outlet air
temperature, fan speed, air flow distribution air-inlet control, and air con-
ditioner compressor operation. It activates when the “AUTO” switch is
pressed, and is used in conjunction with the Temperature control dial to
maintain a constant, comfortable climate within the passenger compart-ment.
The temperature can be set within a range of 65 – 85 °F (18 – 32 °C).
NOTE
The temperature is shown in units of Fahrenheit for US model and in Centigrade for Canadian model.

ECON (economy) mode:
When you press the “AUTO” switch while the system is in the AUTO
mode, it selects the ECON (economy) mode, turning on the“
ECON ” indicator light. In the ECON mode, the compressor runs to
be thrifty with energy consumption. Interior windows tend to fog in this
energy-saving operation. It is therefore recommended that the AUTOmode be used only in high humidity conditions. Manual mode operation:
When the Automatic Climate Control system is operating in the AUTO
mode, pressing the “
”, “”, “MODE”, “A/C” or
“
” switch shifts the operation into the “MANUAL” mode and the
indicator light “AUTO” on the control panel will go out.
When the “
”, “”, “MODE”, “A/C” or “”
switch is pressed, the corresponding function can be controlled inde-
pendently, while automatic control of the other functions are main-tained.
To change the system back to the AUTO mode, press the “AUTO”
switch. n OFF switch
The Automatic Climate Control system turns off (the air conditioner
compressor and fan turn off) when the “OFF” switch is pressed.
When the “OFF” switch is pressed, the outside air introduction mode
(“
” position) is automatically selected.
NOTE Display illumination dimness cancellation (BRIGHT): Setting the light switch to the “p ” or “ a ” position causes the
illuminating icons on the display panel to dim. When travelingwith the lights on in gloomy daylight or in twilight, press the OFFswitch for 1 second or longer if you feel it is too hard to identify
the icons clearly. The brightness comes back to normal.If you wish to dim the icons again, hold down the OFF switchagain or if you can safely do so, turn the light switch OFF andthen place it in the “p ” or “a ” position.

nOUT.TEMP switch
To check the outside air temperature, push the “OUT.TEMP” switch.
The outside air temperature will be displayed for five seconds, and
then the display automatically changes back to the inside air temper-
ature.
The display changes over from the inside air temperature to the out-
side air temperature as its normal indication if you keep the switch
pressed for more than 2 seconds. NOTE You can check the outside air temperature even when the Au-
tomatic Climate Control is off. (The ignition switch should be in the “ON” position.)
In the following cases, the display can indicate a higher tem-
perature than the actual outside air temperature: – In direct sunlight
– When the vehicle is parked for a long period of time with the
engine kept running.– During stop and go driving
n
— Defroster switch
To defrost or dehumidify the windshield and side window, push the
defroster switch “
”. When the “” switch is pushed, re-
gardless whether the air conditioner is operating or not, outside air is
drawn into the passenger compartment, the air conditioner compres-
sor turns on, air flow is directed towards the windshield and side win-dows, and the indicator light “
” on the control panel comes on.
After eliminating the fogging from the windshield, set the air condition- er back in the AUTO mode by pushing the “AUTO” switch or turn off
by pushing the “OFF” switch or “
” switch.

n — Fan speed control switch
HB5021BB
The fan speed control switch has the 5 positions: AUTO position and
4 different fan speed positions.
With the fan speed control switch in the AUTO position, the fan speed
changes automatically corresponding to various conditions: air tem-
perature inside and outside of the passenger compartment, intensityof the sunlight, etc.
Use this switch to select desired fan speed. Fan speed increases with
each press of the switch and returns to the AUTO position. n A/C — Air conditioner switch
NOTE The air conditioner compressor does not operate when the out- side air temperature is below 32 °F (0 °C).
If the windshield starts to fog when the air conditioner is operated in
the AUTO mode, push the air conditioner switch “A/C” to defog and
dehumidify.
When this switch is pushed, the air conditioner compressor turns onand the indicator light “A/C” on the control panel comes on. After
eliminating the fogging from the windshield, set the air conditionerback in the AUTO mode by pushing the “AUTO” switch.

pushed.
n Temperature control dial
HB4033BB
NOTE A setting of about 77 °F (25 °C) throughout the year is recom-
mended. The temperature setting remains even after the ignition switch
is turned to the “OFF”. However, if the battery cables are discon-
nected, the temperature will be set to 77 °F (25 °C) automatically.
Set desired temperature by turning the temperature control dial; turn
the dial clockwise to raise the temperature setting and turn it counter-clockwise to lower it.
The temperature can be set in increments of 1 °F within a range of 65
– 85 °F for US models and in increments of 0.5 °C within a range of 18
– 32 °C for Canadian models.
Even when quick cooling or warming is necessary, you do not have to
change the temperature setting. The Automatic Climate Control sys-
tem operates at maximum performance until the air in the passenger
compartment reaches to the specified temperature.

Temperature sensors
This Automatic Climate Control system employs the several sensors.
These are very delicate parts. Therefore, if these sensors are dam-
aged, it is possible that the Automatic Climate Control system will not
properly control the air temperature in the passenger compartment.
To prevent possible damage to the sensors, please observe the fol-lowing: – Do not allow anything to impact the sensors.
– Be careful not to let water contact the sensors.
– Do not cover the sensors.
The sensors are found at the following locations: –Sun-load sensor (beside the windshield defroster grille)
– In-vehicle temperature sensor (beside the temperature control
dial.)– Ambient sensor (at the backside of the front grille)

Operating tips for heater and air conditionerCleaning ventilator grille
HB5019BC
Always keep the front ventilator inlet grille free of snow, leaves, or oth-
er 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 windowsclosed during the operation of the air conditioner for maximum cool-
ing 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-sea-
son to circulate 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.
