NOTE
When the “
”button or “”button is
pressed the air conditioner compres-
sor automatically operates to quickly
defog the windshield. However the
indicator on the air conditioner button
will not illuminate. At the same time,
the air inlet selection is automatically
set to “outside air ”mode. Automatic climate control
system (if equipped) NOTE .
Operate the automatic climate con-
trol system when the engine is running. . The blower fan rotates at a low
speed when the engine coolant tem-
perature is low.
For efficient defogging or dehumidify-
ing 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 ”indi-
cator light on the control panel illumi-nates.
The automatic climate control system
automatically controls outlet air tempera-
ture, fan speed, air flow distribution air-
inlet control, and air conditioner compres-
sor operation. It activates when the fan
speed control button or the “AUTO ”button
is pressed, and is used to maintain a
constant, comfortable climate within the
passenger compartment. If you press the
defroster button while the automatic cli-
mate control system is deactivated, only
the defroster function will be activated. The temperature can be set within a range
of 61 to 89

setting, press the“”side of the tempera-
ture control button.
Each temperature setting is shown on the
display. When the “LO ”is shown, the
system provides maximum cooling perfor-
mance. When the “HI ” is shown, the
system provides maximum heating perfor-mance. ! DUAL mode
It is possible to make separate tempera-
ture settings for the driver ’s side and
passenger ’s side (DUAL mode).
To activate the DUAL mode:
Press the “DUAL ”button. When the DUAL
mode is activated, the indicator light on the “DUAL ”button illuminates. To deactivate the DUAL mode:
Press the
“DUAL ”button again. When the
DUAL mode is deactivated, the indicator
light on the “DUAL ”button turns off and
the temperature setting for the frontpassenger ’s side becomes the same as
the setting for the driver ’s side.

ter button “
”. When the “”button is
pressed, the air conditioner compressor
automatically operates to quickly defog
the windshield, outside air is drawn into
the passenger compartment, air flow is
directed towards the windshield and front
door windows, and the indicator light on
the button illuminates. After eliminating the fogging from the
windshield, return the climate control
systemtotheFULLAUTOmodeby
pressing the
“AUTO ”button or turn off by
pressing the “OFF ”button.
Alternatively, press the “
”button again
to return the system to the setting that was

pressing the air flow mode selection
button. The selected air flow mode is
shown on the display.
(Ventilation): Air flows through the
instrument panel outlets.
(Bi-level): Air flows through the instru-
ment panel outlets and the foot outlets.
(Heat): Air flows through the instrument
panel outlets, the foot outlets, and some
through the windshield defroster outlets.
(Heat-def): Air flows through the instru-
ment panel outlets, the windshield defros-
ter outlets, and the foot outlets. NOTE
When the
“

conditioner compressor automatically
operates to quickly defog the wind-
shield and the air inlet selection is
automatically set to the “outside air ”
mode. ! Air inlet selection button

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 the air con-
ditioning system checked by your
SUBARU dealer. & 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 system.
& Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steepupgrade. & Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od 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.

Transmitter flash sequence Feature description
Flashes when button is pressed Indicates that the system is transmitting an RF signal.
Two long flashes following re-
mote start activation (transmit-
ter button is pressed two times
within 3 seconds) Indicates that the transmitter did not receive the remote start
activation confirmation from the vehicle system. The transmitter
will automatically send one additional remote start activation
attempt. This usually occurs when the operational range is at its
limit or has been exceeded.
One flash following remote
start activation (transmitter
button is pressed two times
within 3 seconds) Indicates that the engine is running via remote start. If the
transmitter is moved outside of the operating range of the
system, this sequence will timeout after the normal 15-minute
vehicle run cycle.
2 flashes every 5 seconds Indicates that the engine is running via remote start. If the
transmitter is removed outside of the operating range of the
system, this sequence will timeout after the normal 15-minute
vehicle run cycle.
3 flashes Indicates that the engine has turned off due to a remote start
system 15-minute timeout, vehicle safety parameter or normal shutdown. &
Entering the vehicle follow-
ing remote engine start shut- down
An alarm trigger may occur if the vehicle is
opened by the remote keyless entry
transmitter within a few seconds immedi-
ately following remote engine start shut-down. & Pre-heating or pre-cooling
the interior of the vehicle
Models with automatic climate control system:
After the system starts the engine, the
automatic climate control system will
activate the “FULL AUTO ”mode and heat
or cool the interior to the predetermined
median (room) temperature. No pre-
setting of controls is necessary.
Models with manual climate control system:
Before exiting the vehicle, set the tem-
perature controls to the desired setting
and operation. After the system starts the
engine, the heater or air conditioning will
activate and heat or cool the interior to
your setting. Starting and operating
