WARNING
 The cooling function operates
only when the engine is running.Do not leave children or adults
who would normally require the
support of others alone in your
vehicle. Pets should not be left
alone either. On hot, sunny days,
temperatures in a closed vehicle
could quickly become high
enough to cause severe or
possibly fatal injuries to people
or animals.

Automatic Climate Control Operation
2004-3. Automatic ClimateControl OperationWhen this mode is selected, the fan
speed, airflow distribution, air-inlet control,
and air conditioner compressor operation
are automatically controlled. To activate
this mode, perform the following.
1. Press the AUTO button. The FULL
AUTO mode is selected and the “FULL
AUTO” indicator light on the display illumi-
nates.
2. Set the preferred temperature using
the temperature control dial.NOTEOperate the automatic climate
control system when the engine is
running.
 Even when cooling is not necessary,
the air conditioner compressor will
automatically turn on if the tempera-
ture is set much lo wer than the current
outlet air temperature. Even in this
case, the “A/C” indicator light on the
control panel illuminates
 The air conditioner may not operate
in the following cases: - When the cabin temperature is
low
- When the ambient temperature
decreases close to 32°F (0°C) 
The controllable temperature range
may vary depending on the regional
specifications of the vehicle.
 If you operate any of the buttons on
the control panel other than the ON/
OFF button, rear window defogger
button, SYNC button and temperature
control dial(s) during FULL AUTO
mode operation, the “FULL” indicator
light on the control panel will turn off
and the “AUTO” indicator light will
remain illuminated. You can then
manually control the system as desired
using the button you operated. To

To turn off the climate control system,
press the ON/OFF button. Then the air
inlet selection will be set to the following.
 When the air inlet selection is set to
auto mode: Outside air circulation
 When the air inlet selection is set to
manual mode: No change
When the ignition switch is changed to the
“OFF” or “ACC” position from “ON”, the air
inlet mode will automatically change to the
outside air mode regardless of whether it
is the auto mode or manual mode.

Temperature Control
Turn the temperature control dial to set
the preferred interior temperature.NOTEThe controllable temperature range
may vary depending on the regional
specifications of the vehicle.
▼
MAX A/C mode
For quicker cooling, press the MAX A/C
button.
When the MAX A/C mode is on, the
following settings will be changed auto-
matically.
 The air conditioner will turn on.
 The temperature will be set on the
lowest.
 The fan speed will be set on the
maximum speed.
 The air inlet will be set to the recircula-
tion mode.
 The airflow mode setting will be set to
the ventilation mode.
To turn off MAX A/C mode and return the
previous setting, press the MAX A/C
button again. ▼
SYNC mode
When the SYNC mode is turned on, both
the driver’s and front passenger’s side

Operating Tips for Heater and Air Conditioner
204system to the setting that had been
selected before the defroster was acti-
vated.
4-6. Operating Tips for Heaterand Air Conditioner■
Cleaning Ventilator Grille1) Front ventilator inlet grille
2) CondenserAlways 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
Seaso n
Check the air conditioner unit for refrig-
erant leaks, hose conditions, and proper
operation each spring. Have the air condi-
tioning system checked by your SUBARU
dealer.

Cooling and Dehumidifying
in High Humidity and Low
Temperature Weather Condi-
tion
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
conditioner operation whenever the accel-
erator is fully depressed such as during
rapid acceleration or when driving on a
steep upgrade.
■
Refrigerant for Your Climate
Control System1) Air conditioner labelYour air conditioner uses ozone friendly
refrigerant R-1234yf (HFO-1234yf).
Before adding, changing or checking the
refrigerant, check the air conditioner label
in the location shown in the illustration to
confirm the type of refrigerant is used in
your vehicle.
Consult your SUBARU dealer for service.
Repairs needed as a result of using the
wrong refrigerant are not covered under
warranty.
4-7. Air Filtration SystemYour vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the cabin air filter according to
the replacement schedule found in the
“Warranty and Maintenance Booklet”.
This schedule should be followed to main-
tain the filter’s dust collection ability.
Under extremely dusty conditions, the
filter should be replaced more frequently.
Have your filter checked or replaced by
your SUBARU dealer. For replacement,
use only a genuine SUBARU air filter kit.NOTEThe filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.

CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter. Reduction of the airflow through
the vents.Windshield gets easily fogged or
misted.

6-6. USB Power Supply
NOTEThe rated voltage of each USB
terminal is 5 V/2.1 A (total 4.2 A). For
details about the maximum rated
power, refer to "How to Use the USB
Power Supply" 
P217. Before
connecting a device, be sure to read
the instruction manual of the device
and check whether or not this specifi-
cation of the output is supported by the
device. If a device that requires power
exceeding the maximum rating is
connected, power supply or charging
may not be possible. Even if charging
could be completed, the time required
for charging may be longer than when
the genuine charger for that device is
used.
 Depending on the device, charging
may be possible only when a special
 If the plug on your electric appli-
ance is either too loose or too
tight for the accessory power
outlet, this can result in a poor
contact or cause the plug to get
stuck. Only use plugs that fit
properly.Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause battery
discharge.Before driving your vehicle, make
sure that the plug and the cord on
your electrical appliance will not
interfere with your shifting gears
and operating the accelerator and
brake pedals. If they do, do not
use the electrical appliance while
driving.
CAUTION
The specification of a USB
terminal that can be used is the A-
type. If a different specification of
terminal is connected, power
supply or charging may not be
possible, or the device may
malfunction.There is a risk that a connected
device may malfunction or data
may be damaged. The connection
of a device shall be performed at
your responsibility.To avoid an electric shock or a
malfunction, observe the
following precautions.
- Do not connect a USB hub.- Do not insert any metal or
other foreign object into the
USB terminal.- Do not spill water or otherliquid on the USB terminal.
Be careful not to pull the
connected cable. Doing so could
break the USB terminal and the
connected device.
If a device is connected for a long
time when the engine is not
running, doing so may cause the
risk of a discharged battery. Even
when the engine is running, we
recommend that you do not
connect a device for an unneces-
sarily long time.Do not connect a malfunctioning
device. Doing so may cause the
risk of smoke and fire.
