NOTE
Warm air also comes out from the right and left air
outlets. To stop warm air flow from these outlets,
turn the corresponding thumb-wheel down. THeating and defrosting
To direct warm air toward the floor and the windshield:
1. Set the air flow control dial to the “ ” position.
2. Set the temperature control dial to the most com-
fortable level.
3. Set the fan speed control dial to the desired speed. If your vehicle is equipped with an air conditioner,

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.

Automatic climate control system (if
equipped)
Although this climate control system can be used as a
full-automatic climate control system, it can also, if de-
sired, be used as a semi-automatic climate control system.
When it is used as a full-automatic climate control sys-
tem, the outlet air temperature, fan speed, air flow dis-
tribution, air inlet control, and air conditioner compres-
sor operation are all automatically controlled to main-
tain a constant, comfortable temperature inside the vehicle.
NOTE yOperate the automatic climate control system
when the engine is running. y When the engine coolant is cold, the blower
does not run.y In the “AUTO” mode, when the air temperature
in the passenger compartment is sufficiently cool,
the air conditioner compressor does not operate.
For efficient defogging or dehumidifying in cold
weather, press the “A/C” button to operate the air
conditioner compressor. y 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. „

To use as full-automatic climate con-
trol system
Place the temperature control dial in the position for
your desired temperature, then set the other dials and
buttons as described below. The system’s functions
will then switch to AUTO mode and be controlled au-
tomatically. y Air flow control dial: AUTO position
y Fan speed control dial: AUTO position
y Air inlet selection button: Press for at least 1 sec-
ond. (Indicator will flash twice.)y Air conditioner button: Press for at least 1 second.
(Indicator will flash twice.) „ To use as semi-automatic climate con-
trol system
Each function can be individually set to AUTO mode
independently of the others. Any function set to AUTO
mode is controlled automatically. Any function not set
to AUTO mode can be manually adjusted as desired.
The temperature can be set within a range of 65 to85 °F (20 to 30 °C). „
Fan speed control dial
The fan operates only with the ignition switch in the
ON position. The fan speed control dial is used to se-
lect the AUTO (automatic control) mode or to select
the desired fan speed. The dial’s positions and their
functions are as follows:
OFF: The fan does not operate.
AUTO: The fan speed is adjusted automatically in ac-
cordance with the air temperature inside and outside
the passenger compartment, the intensity of sunlight,
and other factors. SUBARU recommends using the
AUTO position.
Other positions: The fan speed can be adjusted in
seven steps.

NOTE
With the fan speed control dial in the AUTO posi-
tion and the air flow control dial in the “ ”,
“ ”, or “ ” position, the fan does not oper-
ate during engine warmup until the engine coolant
temperature exceeds approx. 122 °F (50 °C).
„ Temperature control dial
This dial is used to set the desired interior tempera-
ture. With the dial set to your desired temperature, the
system automatically adjusts the temperature of air
supplied from the outlets such that the desired temper-
ature 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. „
Air flow control dial
This dial has the following six positions. The outlets
from which air is supplied in each position are as fol-
lows:AUTO: The air flow control is adjusted automatically in
accordance with the air temperature inside and out-
side the passenger compartment, the intensity of sun-
light, and other factors. SUBARU recommends using

NOTE
When the dial is placed in the “ ” or “ ” po-

ton to the ON position for fast cooling with the air con-
ditioner or when driving on a dusty road. The indicator
light will come on.
OFF position (Outside Air): Outside air is drawn into
the passenger compartment. Push the air inlet selec-
tion button to the OFF position when the interior has
cooled to a comfortable temperature and the road is
no longer dusty. The indicator light will go off.
AUTO: When the air inlet selection button is pressed
for at least one second, the indicator flashes twice.
