. If your vehicle is involved in a
rear-end collision, have an
authorized SUBARU dealer in-
spect the active head restraints.
. The active head restraints may
not operate in the event the
vehicle experiences only a slight
impact in the rear.
. The active head restraints may be
damaged if they are pushed hard
from behind or subjected to
shock. As a result, they may not
function if the vehicle suffers a
rear impact. Seat heater (if equipped)

Front passenger ’s side
1) HI–Rapid heating
2) LO–Normal heating
The seat heater operates when the igni-
tion switch is either in the “Acc ”or “ON ”
position.
To turn on the seat heater, push the “LO ”
or “HI ”position on the switch, as desired,
depending on the temperature. Selecting the “HI ”position will cause the seat to heat
up quicker.
The indicator located on the switch comes
on when the seat heater is in operation.
When the vehicle ’s interior is warmed
enough or before you leave the vehicle,
be sure to turn the switch off. Seat, seatbelt and SRS airbags

Front fog light button (if equipped)
The front fog lights operate only when the
headlights are on low beam. Push the
front fog light button to turn the front fog
lights on.
Press the button again to turn them off.
The indicator light located on the button
will illuminate when the front fog lights areon. Wiper and washer
WARNING
In freezing weather, do not use the
windshield washer until the wind-
shield is sufficiently warmed by the
defroster.
Otherwise the washer fluid can
freeze on the windshield, blocking
your view.
CAUTION
. Do not operate the washer con-
tinuously for more than 10 sec-
onds, or when the washer fluid
tank is empty. This may cause
overheating of the washer motor.
Check the washer fluid level
frequently, such as at fuel stops.
. Do not operate the wipers when
the windshield or rear window is
dry. This may scratch the glass,
damage the wiper blades and
cause the wiper motor to burn
out. Before operating the wiper
on a dry windshield or rear
window, always use the wind-
shield washer. .
In freezing weather, be sure that
the wiper blades are not frozen to
the windshield or rear window
before switching on the wipers.
Attempting to operate the wiper
with the blades frozen to the
window glass could cause not
only the wiper blades to be
damaged but also the wiper mo-
tor to burn out. If the wiper
blades are frozen to the window
glass, be sure to operate the
defroster, windshield wiper dei-
cer (if equipped) or rear window
defogger before turning on the
wiper.
. If the wipers stop during opera-
tion because of ice or some other
obstruction on the window, the
wiper motor could burn out even
if the wiper switch is turned off. If
this occurs, promptly stop the
vehicle in a safe place, turn the
ignition switch to the “LOCK ”
position and clean the window
glass to allow proper wiper op-eration.
. Use clean water if windshield
washer fluid is unavailable. In
areas where water freezes in
winter, use SUBARU Windshield
Washer Fluid or the equivalent.

&Heater operation
! Defrosting or defogging the wind- shield
To direct warm air to the windshield and
front door windows:
1. Set the air inlet selection lever to the “
”position.
2. Set the air flow control dial to the “
”
position.
3. Turn the temperature control dial all
the way to the right.
4. Set the fan speed control dial to the
highest speed.
If your vehicle is equipped with an air
conditioner, when the “
”or “”position
is selected, the air conditioner compressor
automatically operates regardless of the position of the air conditioner button to
defog the windshield quickly.
However, the air conditioner indicator light
does not come on at this time.
NOTE
Warm air also comes out from the right
and left air outlets. To stop warm air
flow from these outlets, turn the corre-
sponding knob clockwise. ! Heating and defrosting
To direct warm air toward the floor and the windshield:
1. Set the air inlet selection lever to the “
”position.
2. Set the air flow control dial to the “
”
position.
3. Set the temperature control dial to the most comfortable level.
4. Set the fan speed control dial to the
desired speed.

Bi-level heating
This setting allows you to direct air of
different temperatures 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 lever to the “
”position.
2. Set the air flow control dial to the “
”
position.
3. Set the temperature control dial to the
desired temperature 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 difference
between the air from the instrument panel outlets and the air from the foot outlets. !
Ventilation
To force outside air through the instrument
panel outlets:
1. Set the air inlet selection lever to the “
”position.
2. Set the air flow control dial to the “
”
position.
3. Set the temperature control dial all the
way left.
4. Set the fan speed control dial to the
desired speed.
When driving on a dusty road, set the air
inlet selection lever to the “
”position.

&Fan speed control dial
The 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 25 steps. NOTE
With the fan speed control dial in the
AUTO position and the air flow control
dial in the
“
”, “”,or “”position,
the fan does not operate during engine
warm-up until the engine coolant tem-
perature exceeds approx. 122 8F (50 8C).
& Temperature control dial
This 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 andmaintained.
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 heatingperformance. &
Air flow control dial
This dial has the following six positions.
The outlets from which air is supplied in
each position are as follows: AUTO: The air flow control is adjusted
automatically in accordance with the air
temperature inside and outside the pas-
senger compartment, the intensity of sun-
light, and other factors. SUBARU recom-
mends using the AUTO position.

other factors. Pressing the button cancels the“AUTO ”mode. SUBARU recommends
using the AUTO position.
NOTE
The air conditioner ’s compressor does
not operate with an outside tempera-
ture of 32 8F(0 8C) or lower.
& Temperature sensors
1) Interior air temperature sensor
2) Solar sensor
The automatic climate control system
employs several sensors. These sensors
are delicate. If they are not treated
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 windshield defros-
ter grille– Interior air temperature sensor: beside
the fan speed control dial– Outside temperature sensor: behind
front grille. Operating tips for heater and
air conditioner &
Cleaning ventilation 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 Climate control
