Compass mirror (if equipped)
HB6019BC
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The inside electronic compass mirror has an anti-
glare feature which automatically reduces glare
coming from headlights of vehicles behind you. It also contains a built-in compass. By pressing and releasing the left button, the au-
tomatic dimming function is toggled on or off. Whenthe automatic dimming function is on, the auto dim-
ming indicator light (green) located to the right of the button will illuminate.
By pressing and releasing the right button, the
compass 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
surface turns bright if the transmission is shifted into
reverse. This is to ensure good rearward visibility
during reversing.
n Photosensors
HB6020BA
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 sen-
sors 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. Periodi-
cally wipe the sensors clean using a piece of dry
soft cotton cloth or an applicator.
n Compass calibration
1. For optimum calibration, switch off all nonessen-
tial 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 me-
tallic objects or structures and make certain the igni-
tion switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then
release, 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).
5. The compass is now calibrated. Further calibra-
tion is not required. The compass will automatically
calibrate from this point forward. n
Compass zone adjustment
HB6021AA
Compass calibration zones
1. The zone setting is factory preset to Zone 8. Re- fer to the “Compass calibration zone ” map shown
above or one attached to the end of this manual to
verify that the compass zone setting is correct for your geographical location.
2. Press and hold the right button for 3 seconds
then release, and the word “ZONE” will briefly ap-
pear and then the zone number will be displayed.
3. Press the right hand button repeatedly to cycle
the display through all possible zone settings. Stop

The mirrors can also be adjusted manually.
Outside mirror defogger (if equipped)
The outside mirror defogger shares the switch with
rear window defogger.
The outside mirror defogger operates only when the
ignition switch is in the “ON” position.
HB5009BC
1) OFF
2) ON 3) Push
To turn on the outside mirror defogger, push the
switch. To turn it off, push the switch again. The indi-
cator light located on the switch lights up while the
outside mirror defogger is operating.
The defogger will automatically shut off after about 15 minutes. If the mirror clears before that time,
push the switch to turn it off. It also turns off when
the ignition switch is turned to the
“ACC” or “LOCK”
position. If defrosting or defogging is desired when
you restart your vehicle, you have to push the switch
to turn it on again. NOTE While the outside mirror defogger is operating, the rear window defogger also operates.
CAUTION
To prevent the battery from being discharged,
do not operate the defogger continuously for
any longer than necessary.

To direct warm air toward the floor:
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 com-
fortable level.
4. Set the fan speed control dial to the desired speed. NOTE
Warm air also comes out from the right and left
air outlets. To stop warm air flow from these out-lets, turn the corresponding knob clockwise.
Bi-level heating
HG4026AA
This setting allows you to direct air of different tem-
peratures 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 desiredspeed.
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.

Operating tips for heater and air conditioner Cleaning ventilator grille
HG4016BA
Always keep the front ventilator inlet grille free of
snow, leaves, or other obstructions to ensure effi-
cient heating and defrosting. Since the condenser is
located in front of the radiator, this area should be
kept clean because cooling performance is im-
paired 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 win- dows 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 win-dows closed during the operation of the air condi-
tioner for maximum cooling efficiency. Lubrication oil circulation in the refrigerant circuit
Operate the air conditioner compressor at a low en- gine speed (at idle or low driving speeds) a few
minutes each month during the off-season to circu-
late its oil. Checking air conditioning system before 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.
