housing and damage the mirror. !
Photosensors
The mirror has a photosensor attached on
both the front and back sides. During
nighttime driving, these sensors detect
distracting glare from vehicle headlights
behind you and automatically dim the
mirror to eliminate glare and preserve
your vision. For this reason, use care not
to cover the sensors with stickers, or other
similar items. Periodically wipe the sen-
sors clean using a piece of dry soft cotton
cloth or an applicator. !

&Air conditioner button
The button positions and their functions
are as follows. ON: The air conditioner operates while the
fan is running.
Push the button to select this position. The
indicator light will illuminate. OFF: The air conditioner does not oper-
ate.
Push the button again to select this
position. The indicator light will turn off. AUTO: Turn the fan speed control dial and
airflow control dial to the AUTO position.
The air conditioner compressor operation
is then adjusted automatically in accor-
dance with the air temperature inside and
outside the passenger compartment, the
intensity of sunlight, and other factors. Pushing the button cancels the
“AUTO ”
mode. To return to “AUTO ”mode, turn the
fan speed control dial or airflow control
dial to a position other than the AUTO
position. Then turn to “AUTO ”mode.
SUBARU recommends using the AUTOposition.
NOTE
The air conditioner ’s compressor does
not operate with an outside tempera-
ture of 32 8F(0 8C) or lower. &

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

&Auto mode
In the auto mode, the system estimates
the driving and road conditions using
signals from the wheel speed sensor,
throttle position sensor, steering angle
sensor and brake switch, etc. According
to the result, it electronically and auto-
matically controls the degree of limitation
of the differential action (LSD torque) to
optimize the differential action of the
center differential. When the ignition
switch is turned ON, the “AUTO ”indicator
light on the combination meter illuminates. The auto mode has 3 modes as follows.
Mode Operation
AUTO [+] This mode emphasizes traction control and strengthens the
limitation of differential action
that is suitable for driving on
slippery roads for vehicle stabi-
lity.
AUTO This mode is suitable for most driving situations.
AUTO [ ] This mode is suitable when you
seek quick response from the
steering wheel and smooth driving.
! Mode setting method
In most situations, it is recommended that the “AUTO ”mode is selected.
Push the control switch forward to select the
“AUTO [+] ”mode. After setting the
mode, “
”on the combination meter
illuminates.
Pull the control switch rearward to select the “AUTO [ ]” mode. After setting the
mode, “
”on the combination meter
illuminates.
When the “AUTO [+] ”mode is selected,
pull the control switch rearward to change
to the “AUTO ”mode. When the “AUTO
[ ]” mode is set, push the control switch
forward to change to the “AUTO ”mode.

Tire pressure monitoring
system (TPMS) (U.S.-spec.models)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also,
this system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a
sharp object).
WARNING
If the low tire pressure warning light
illuminates while driving, never
brake suddenly and keep driving
straight ahead while gradually redu-
cing speed. Then slowly pull off the
road to a safe place. Otherwise an
accident involving serious vehicle
damage and serious personal injury
could occur.
Check the pressure for all four tires
and adjust the pressure to the COLD
tire pressure shown on the tire
placard on the door pillar on thedriver ’s side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures increase
accordingly. Be sure to let the tires
cool thoroughly before adjusting
their pressures to the standard
values shown on the tire placard.
Refer to “Tires and wheels ”F 11-23.
The tire pressure monitoring system
does not function when the vehicle
is stationary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)
to start the TPMS re-checking of the
tire inflation pressures. If the tire
pressures are now above the severe low pressure threshold, the low tire
pressure warning light should turn
off a few minutes later.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors. If the light
illuminates steadily after blinking for
approximately one minute, promptly
contact a SUBARU dealer to have
the system inspected.

CAUTION
. Do not place metal film or any
metal parts in the cargo area/
trunk. This may cause poor re-
ception of the signals from the
tire pressure sensors, and the
tire pressure monitoring system
will not function properly.
. FCC WARNING
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user ’s authority
to operate the equipment.
