& Outside mirrors! Convex mirror (passenger side)
WARNING
Objects look smaller in a convex
mirror and farther away than when
viewed in a flat mirror. Do not use
the convex mirror to judge the
distance of vehicles behind you
when changing lanes. Use the inside
mirror (or glance backwards) to
determine the actual size and dis-
tance of objects that you view in
convex mirror. !

2) Direction control switchThe remote control mirrors operate only
when the ignition switch is in the “ON”or
“Acc ”position.
1. Press either end of the selection
switch, “L”for the left, “R”for the right.
2. Move the direction control switch in the

window defogger. Some models are also
equipped with an outside mirror defogger
and/or windshield wiper deicer. The de-
fogger and deicer system is activated only
when the ignition switch is in the “ON”
position.Manual climate control system
Automatic climate control systemTo activate the defogger and deicer
system, push the control switch that is
located on the climate control panel. The
rear window defogger, outside mirror
defogger and windshield wiper deicer are
activated simultaneously. The indicator
light on the control switch illuminates while
the defogger and deicer system is acti-
vated.
To turn them off, push the control switch
again. They also turn off when the ignition
switch is turned to the “Acc”or “LOCK”
position.
The defogger and deicer system will
automatically shut off after approximately
15 minutes. If the rear window and the
outside mirrors have been cleared and the windshield wiper blades have been deiced
completely before that time, push the
control switch to turn them off. If defrost-
ing, defogging or deicing is not complete,
you have to push the control switch to turn
them on again.
For models with the automatic climate
control system,
it is possible to set the
defogger and deicer system for the con-
tinuous operation mode as follows.
. Models with genuine SUBARU navi-
gation system:
The setting can be changed for the
continuous operation mode using the
navigation monitor. For details, refer to
the Owner ’s Manual supplement for the
navigation system.
The setting can also be changed by a
SUBARU dealer. Contact your SUBARU
dealer for details.
. Models without genuine SUBARU
navigation system:
The setting can be changed by a
SUBARU dealer. Contact your SUBARU
dealer for details.
If the battery voltage drops below the
permissible level, continuous operation of
the defogger and deicer system is can-
celed and the system stops operating.

! Fan speed control dial
The fan operates only when the ignition
switch is turned to the “ON”position. The
fan speed control dial is used to select
four fan speeds.
! Airflow control dial
Each dial position activates the following
air outlets.
(Ventilation): Instrument panel outlets(Bi-level): Instrument panel outlets and
foot outlets(Heat): Foot outlets, both side outlets of
the instrument panel and some through
windshield defroster outlets (A small
amount of air flows to the windshield and
both side windows to prevent fogging.)(Heat-def): Windshield defroster out-
lets, foot outlets and both side outlets of
the instrument panel: Windshield defroster outlets and both
side outlets of the instrument panel
For details, refer to “Airflow selection”F 4-
2.
NOTEWhen the dial is placed in the “
”or
“
” position, the air conditioner com-
pressor operates automatically regard- less of the position of the air condi-
tioner button to defog the windshield
more quickly. 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.
In this state, you cannot select “recir-
culation ”mode by manually pressing
the air inlet selection button.
Also, you cannot stop the air condi-
tioner compressor by pressing the air
conditioner button.
! Air conditioner button
The air conditioner operates only when
the engine is running.
Push the air conditioner button while the
fan is in operation to turn on the air conditioner. The indicator light will illumi-
nate.
Push it again to turn off the air conditioner.

Air inlet selection button
ON position (recirculation): Interior air is
recirculated inside the vehicle. Push the
air inlet selection button to the ON posi-
tion. The indicator light will illuminate.
Place 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.
Push the air inlet selection button again to
the OFF position. The indicator light will
turn off.

selected, the air conditioner compres-
sor automatically operates regardless
of the position of the air conditioner
button to defog the windshield more
quickly. At the same time, the air inlet
selection is automatically switched to
the OFF position (outside air). How-
ever, the air conditioner indicator light
does not illuminate at this time.
. When defrosting, defogging or heat-
ing, warm air is also emitted from the
right and left air outlets. To stop warm
airflow from these outlets, turn the
corresponding thumb wheel down. !
Defrosting or defogging the wind-
shield
To direct warm air to the windshield and
front door windows:
1. Set the airflow control dial to the “
”
position.
2. Turn the temperature control dial all
the way to the right.
3. Set the fan speed control dial to the
highest speed. !
Heating and defrosting
To direct warm air toward the floor and the
windshield:
1. Set the airflow control dial to the “
”
position.

& Fan speed control dialThe fan operates only with the ignition
switch in the ON position. The fan speed
control dial is used to select 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 auto-
maticallyinaccordancewiththeair
temperature inside and outside the pas-
senger compartment, the intensity of sun-
light, and other factors. SUBARU recom-
mends using the AUTO position.
Other positions: The fan speed can be
adjusted in 7 steps.
NOTEWith the fan speed control dial in the
AUTO position and the airflow control
dial in the “
”, “
”,or “
”position,
the fan does not operate during engine
warm-up until the engine coolant tem-
perature exceeds approximately 1228 F
(50 8C).
& Temperature control dialThis dial is used to set the desired interior
temperature. With the dial set to your
desired temperature, the system automa-
tically 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 per-
formance. If the dial is turned fully clock-
wise, the system gives maximum heating
performance.

Airflow control dialEach dial position activates the following
air outlets.

properly and become damaged, the sys-
tem may not be able to control the interior
temperature correctly. To avoid damaging
the sensors, observe the following pre-
cautions.
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows.
– Solar sensor: beside the windshield
defroster grille.
– Interior air temperature sensor: near
the ignition switch.
– Outside temperature sensor: behind
the front grille.
Operating tips for heater and
air conditioner& Cleaning ventilation grilleAlways keep the front ventilation 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 sunlightAfter 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 circuitOperate 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-
sonCheck 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 conditionsUnder 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
