!Bi-level heating
This setting allows you to direct air of different temper-
atures from the instrument panel and foot outlets. The
air from the foot outlets is slightly warmer than from the
instrument panel outlets.
1. Set the air inlet selection button to the OFF posi-tion.
2. Set the air flow control dial to the “ ” position.
3. Set the temperature control dial to the desired tem-perature level.
4. Set the fan speed control dial to the desired speed.
Setting the temperature control dial fully turned to the
red area or blue area decreases the temperature dif-
ference between the air from the instrument panel out-
lets and the air from the foot outlets. ! Ventilation

Climate control
NOTE
In a vehicle equipped with an air conditioner, when
the dial is placed in the “ ” position or “ ”
position the air conditioner compressor automati-
cally operates to quickly defog the windshield.
However the indicator on the air conditioner but-
ton will not come on. At the same time, the air inlet
selection is automatically set to “outside air” mode.
In this state, you cannot select “recirculation”
mode by manually pressing the air inlet selection button.
Also, you cannot stop the air conditioner com-
pressor by pressing the air conditioner button.
Automatic climate control system (if
equipped)
NOTE "
Operate the automatic climate control system
when the engine is running. " The blower fan rotates at a low speed when the
engine coolant temperature is low.
For efficient defogging or dehumidifying in cold
weather, press the “A/C” button. " Even when cooling is not necessary, setting the
temperature much lower than the current outlet air
temperature turns on the air conditioner compres-
sor 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 dis-
tribution air-inlet control, and air conditioner compres-
sor operation. It activates when the “AUTO” button is
pressed, and is used to maintain a constant, comfort-
able climate within the passenger compartment.
The temperature can be set within a range of 65 to 85 °F (18 to 32 °C).

Passenger’s side
It is possible to make separate temperature settings
for the driver’s side and passenger’s side. Each tem-
perature setting is shown on the display. With the dial
set at your desired temperature, the system automati-
cally adjusts the temperature of air supplied from the
outlets such that the desired temperature is achieved
and maintained.
If the dial is turned fully counterclockwise, the system
gives maximum cooling performance. If the dial is
turned fully clockwise, the system gives maximum
heating performance. !
– Defroster button
To defrost or dehumidify the windshield and front door
windows, push the defroster button “ ”. When the
“ ” button is pushed, regardless whether the air
conditioner is operating or not, outside air is drawn into
the passenger compartment, the air conditioner com-
pressor turns on, air flow is directed towards the wind-
shield and front door windows, and the indicator light
on the button comes on.
After eliminating the fogging from the windshield, re-turn the climate control system to the AUTO mode by
pushing the “AUTO” button or turn off by pushing the
“OFF” button.
Alternatively, push the “ ” button again to return

!Air flow mode selection button
Select the desired air flow mode by pushing the air
flow mode selection button. The selected air flow
mode is shown by the display. (Ventilation): Air flows through the instrument panel
outlets.
(Bi-level): Air flows through the instrument panel
outlets and the foot outlets.
(Heat): Air flows through the instrument panel out-
lets, the foot outlets, and some through the windshield
defroster outlets. (Heat-def): Air flows through the instrument panel
outlets, the windshield defroster outlets, and the foot
outlets. ! Air inlet selection button
Select air flow by pushing the air inlet selection button
“/” .
The selected air inlet setting is shown on the control
panel.
(Recirculation): Interior air recirculates inside the
passenger compartment. Use this position when
quickly cooling down the passenger compartment or
to prevent outside air from entering the passenger
compartment. When the recirculation mode is select-

The sensors are located as follows:
– Solar sensor: beside windshield defroster grille
– 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 con-
ditioner !
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 ac-
cumulation 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 cool- ing efficiency. ! Lubrication oil circulation in the refrig-
erant circuit
Operate the air conditioner compressor at a low en-
gine speed (at idle or low driving speeds) a few min-
utes each month during the off-season to circulate its
oil. ! Checking air conditioning system be-
fore summer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and proper operation each spring.
Have your SUBARU dealer perform this check. !
Cooling and dehumidifying in high hu-
midity and low temperature weather condition
Under certain weather conditions (high relative humid-
ity, 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 system. ! Air conditioner compressor shut-off
when engine is heavily loaded
To improve acceleration and gas mileage, the air con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accelera-
tion 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 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.

In case of emergency
Do not jump start unless cables in suitable con-
dition are available."
A running engine can be dangerous. Keep
your fingers, hands, clothing, hair and tools
away from the cooling fan, belts and any other
moving engine parts. Removing rings, watches
and ties is advisable. " Jump starting is dangerous if it is done incor-
rectly. If you are unsure about the proper proce-
dure for jump starting, consult a competent me-
chanic.
When your vehicle does not start due to a run down
(discharged) battery, the vehicle may be jump started
by connecting your battery to another battery (called
the booster battery) with jumper cables. ! How to jump start
1. Make sure the booster battery is 12 volts and the
negative terminal is grounded.
2. If the booster battery is in another vehicle, do not let
the two vehicles touch.
3. Turn off all unnecessary lights and accessories.
4. Connect the jumper cables exactly in the sequence
illustrated.

In case of emergency
– CONTINUED –
Confirm that the cooling fan is turning. If the fan is not
turning, immediately turn the engine off and contact
your authorized dealer for repair.
3. After the engine coolant temperature has dropped, turn off the engine.
If the temperature gauge stays at the overheated
zone, turn the engine off.
4. After the engine has fully cooled down, check the
coolant level in the reserve tank.
If the coolant level is below the “MIN” mark, add cool-
ant up to the “MAX” mark.
5. If there is no coolant in the reserve tank, add cool-
ant to the reserve tank. Then remove the radiator cap
and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first
wrap a thick cloth around the radiator cap, then turn
the cap counterclockwise slowly without pressing
down until it stops. Release the pressure from the ra-
diator. After the pressure has been fully released, re-
move the cap by pressing down and turning it.Towing
Never tow AWD vehicles (both AT and MT) with
the front wheels raised off the ground while the
rear wheels are on the ground, or with the rear
wheels raised off the ground while the front
wheels are on the ground. This will cause the
vehicle to spin away due to the operation or de-
terioration of the center differential.
If towing is necessary, it is best done by your SUBARU
