dicator light (green) located to the right of the button
will illuminate.y
By pressing and releasing the right button, the com-
pass display is toggled on or off. When the compass is
on, an illuminated compass reading will appear in the
lower part of the mirror.
Even with the mirror in anti-glare mode, the mirror sur-
face turns bright if the transmission is shifted into re-
verse. This is to ensure good rearward visibility during reversing. T Photosensors
The mirror has a photosensor attached on both the
front and back sides. If the glare from the headlights of vehicles behind you strikes the mirror, these sensors
detect it and make the reflection surface of the mirror
dimmer to help prevent you from being blinded. For
this reason, use care not to cover the sensors with
stickers, or other similar items. Periodically wipe the
sensors clean using a piece of dry soft cotton cloth or
an applicator. T
Compass calibration
1. For optimum calibration, switch off all nonessential
electrical accessories (rear window defogger, heater/
air conditioning system, spotlight, etc.) and ensure all
doors are shut.
2. Drive to an open, level area away from large metal-
lic objects or structures and make certain the ignition
switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then re-
lease, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears from
the display (about two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary should out-
side influences cause the mirror to read inaccurately.
You will know that this has occurred if your compass
begins to read in only limited directions. Should you
encounter this situation, return to step one of the
above procedure and recalibrate the mirror.

Manual heating and air conditioning
system „Control panel
1) Temperature control dial
2) Fan speed control dial
3) Air flow control dial
4) Air conditioner button
5) Air inlet selection button
6) Rear window defogger button (Refer to “Rear window defogger switch” in chapter 3.)
T Temperature control dial
This dial regulates the temperature of air flow from the air outlets over a range from the blue area (cool) to red
area (warm). T
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. T Air flow control dial
This dial has the following five positions:
: Air flows through the instrument panel outlets.: Air flows through the instrument panel outlets
and the foot outlets.
: Air flows through the foot outlets and some
through the windshield defroster outlets.
: Air flows through the windshield defroster outlets
and foot outlets.
: Air flows through the windshield defroster out-
lets.

this switch is pushed.
: Outside air is drawn into the passenger com-
partment. When the air conditioning system is operat-
ed in the “AUTO” mode, this position is selected auto-
matically. The indicator light “ ” on the control
panel comes on when this switch is pushed. T Temperature control dial
1) Temperature control dial
NOTE
The temperature setting remains even after the ig-
nition switch is turned to the “OFF”. However, if
the battery cables are disconnected, the tempera- ture will be set to 77
°F (25 °C) automatically.
Set desired temperature by turning the temperature
control dial; turn the dial clockwise to raise the temper-
ature setting and turn it counterclockwise to lower it.
The temperature can be set in increments of 1 °F with-
in a range of 65 to 85 °F for US models and in incre-
ments of 0.5 °C within a range of 18 to 32 °C for Cana-
dian models.
Even when quick cooling or warming is necessary,
you do not have to change the temperature setting.
The Automatic Climate Control system operates at
maximum performance until the air in the passenger
compartment reaches to the specified temperature.

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 cool- ing efficiency. „ Lubrication oil circulation in the refrig-
erant circuit
Operate the air conditioner compressor at a low en-
gine speed (at idle or low driving speeds) a few min-
utes each month during the off-season to circulate its
oil. „ Checking air conditioning system be-
fore summer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and proper operation each spring.
This check is best performed by your SUBARU dealer. „
Cooling and dehumidifying in high hu-
midity and low temperature weather condition
Under certain weather conditions (high relative humid-
ity, 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 con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accerela-
tion or when driving on a steep upgrade. „ Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method 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 (if equipped)
If your vehicle’s air conditioning system is equipped
with a optional air filtration system, replace the filter el-
ement according to the replacement schedule shown
below. This schedule should be followed to maintain
the filter’s dust collection ability. Under extremely
dusty conditions, the filter should be replaced more
frequently. Since the filter element is a viscous type, it
is unnecessary to clean or wash the element. Have
your filter checked or replaced by your SUBARU deal- er.
Replacement schedule:
Every 12 months or 9,300 miles (15,000 km) whichev-
er comes first
NOTE
The filter can influence the air conditioning, heat-
ing and defroster performance if not properly
maintained.

hicle control could lead to an accident. TMeasuring and adjusting air pressure to
achieve proper inflation
Check and, if necessary, adjust the pressure of
each tire (including the spare) at least once a
month and before any long journey. Check the
tire pressures when the tires are cold. Use a
pressure gauge to adjust the tire pressures to the
specific values. Driving even a short distance
warms up the tires and increases the tire pres-
sures. Also, the tire pressures are affected by the
ambient temperature. It is best to check tire pres-
sure outdoors before driving the vehicle. When a
tire becomes warm, the air inside it expands,
causing the tire pressure to increase. Be careful
not to mistakenly release air from a warm tire to
reduce its pressure. „ Glossary of tire terminology
y Cold tire pressure
The pressure in a tire that has been driven less
than 1 mile or has been standing for three hours
or more. y Maximum inflation pressure The maximum cold inflation pressure to which a
tire may be inflated. y
Recommended inflation pressure
The cold inflation pressure recommended by a
vehicle manufacturer. y Intended outboard sidewall
1)The sidewall that contains a whitewall, bears
white lettering or bears manufacturer, brand,
and/or model name molding that is higher or
deeper than the same molding on the other
sidewall of the tire, or
2)The outward facing sidewall of an asymmet-
rical tire that has a particular side that must al-
ways face outward when mounting on a vehi- cle.
y Accessory weight
The combined weight (in excess of those stan-
dard items which may be replaced) of floor mats,
leather seats and cross bars to the extent that
these items are available as factory-installed
equipment (whether installed or not). y Curb weight
The weight of a motor vehicle with standard
equipment including the maximum capacity of fu-
el, oil, and coolant and air conditioning.
