Seat heater (if equipped)
The seat heater is equipped in the front seats.
The seat heater operates when the igni-
tion switch is either in the “Acc ”or “ON ”
position.
CAUTION
. There is a possibility that people
with delicate skin may suffer
slight burns even at low tempera-
tures if they use the seat heater
for a long period of time. When
using the heater, always be sure
to warn the persons concerned.
. Do not put anything on the seat
which insulates against heat,
such as a blanket, cushion, or
similar items. This may cause the
seat heater to overheat.
NOTE
Use of the seat heater for a long period
of time while the engine is not running
can cause battery discharge. &

&Temperature gauge (turbo models)
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “Engine overheating ”F9-
13. REV indicator light and buz-

WARNING
Continued operation with the air

&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 7 steps. NOTE
With 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 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. &
Airflow control dial
Each dial position activates the following
air outlets. AUTO: The airflow 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.

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 grille
Always 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 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 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
