minated by operating the light control
switch from the “
”(off) position to the
“” or “”position.

&Daytime running light system
WARNING
The brightness of the illumination of
the high beam headlights is reduced
by the daytime running light system.
The light switch must always be
turned to the “
”position when it
is dark outside.
The high beam headlights will automati-
cally illuminate at reduced brightness
when the following conditions are fulfilled.
. The engine is running.
. The parking brake is fully released.
. The light control switch is in the
“AUTO ”(if equipped), “
”or off position.
. For CVT models, the select lever is in a
position other than the “P”position.
NOTE
. When the light switch is in the “”
position, the instrument panel illumina-
tion, front side marker lights, tail lights
and license plate lights are also illumi-
nated.
. For models with the auto on/off
headlights, while the light control
switch is in the “AUTO”position and
the system is activated to the auto-on
mode depending on the ambient light level, the high beam headlights that
have illuminated at reduced brightness
turn off, and the low beam headlights
turn on alternatively. At this time, the

Automatic climate control
operation (type B, C and D)
When 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.
&Type B
1. Turn the airflow mode selection dial
and fan speed control dial to the “AUTO”
position.
2. Set the preferred temperature using
the temperature control dial.
NOTE
. Each function can be individually
set to the AUTO mode independently of
the other functions. Any function set to
the AUTO mode is controlled automa-
tically. Any function not set to the
AUTO mode can be manually adjusted
as desired.
. The controllable temperature range
may vary depending on the regional
specifications of the vehicle.
To turn off the climate control system, turn
the fan speed control dial to the “OFF ”
position. Then the air inlet selection will be set as follows.
.
when the AUTO mode is selected: OFF
(outside air)
. when the AUTO mode is not selected:
the mode that was selected when turning
off the climate system will be selected.
& Type C and D
1. Depress the “AUTO ”button. The
indicator light “FULL AUTO ”on the display
illuminates.
2. Set the preferred temperature using
the temperature control dial.
NOTE
. 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 “OFF”
button, rear window defogger 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 change the system
back to the FULL AUTO mode, press
the “AUTO ”button. To turn off the climate control system,
press the
“OFF ”button. Then the air inlet
selection will be set to OFF (outside air).
& Operation tips
. Operate the automatic climate control
system when the engine is running.
. Even when cooling is not necessary,
setting the temperature much lower than
the current outlet air temperature turns on
the air conditioner compressor automati-
cally and the “A/C”indicator light on the
control panel illuminates.

button again.
NOTE
For efficient defogging or dehumidify-
ing in cold weather, turn on the air
conditioner. However, if the ambient
temperature decreases to approxi-
mately 32 8F(0 8C), the air conditioner
compressor will stop operating.
& Air inlet selection
Select the air inlet by pressing the air inlet
selection button.
ON position (recirculation): Interior air is
recirculated inside the vehicle. Press the
air inlet selection button to the ON position
for fast cooling with the air conditioner or
when driving on a dusty road.
OFF position (outside air): Outside air is
drawn into the passenger compartment.
Press the air inlet selection button to the
OFF position when the interior has cooled to a comfortable temperature and the road
is no longer dusty.
WARNING
Continued operation in the ON posi-
tion may fog up the windows. Switch
to the OFF position as soon as the
outside conditions are no longer
dusty.
NOTE
.
When the indicator light on the air
inlet selection button is flashing at
engine starting, a malfunction might
be occurring in the electrical system.
Contact your SUBARU dealer for in-
spection.
. The indicator light on the air inlet
selection button may flash in the
following cases. However, this does
not indicate a malfunction.
–After the vehicle battery has been
disconnected and reconnected.
– When the vehicle battery voltage
is low.

Climate control/Air filtration system
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 conditions
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 steep
upgrade.
&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.
Air filtration system
Your vehicle’ s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule found in the
“Warranty and Maintenance Booklet ”. This
schedule should be followed to maintain
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.
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.
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
