WARNING
Never drive the vehicle with the head re-
straints removed because they are designedto reduce the risk of serious neck injury in the
event that the vehicle is struck from the rear.Seat heater (if equipped)
The seat heater operates when the ignition 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.

1)HI – Rapid heating
2) LO – Normal heating
The indicator located on the switch comes on when the seat heater is in operation. When the vehicle ’s in-
terior is warmed enough or before you leave the ve-
hicle, be sure to turn the switch off.
CAUTION
There is a possibility that people with deli-
cate skin may suffer slight burns even at low
temperatures if he/she uses 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 insu-
lates against heat, such as a blanket, cushion,or similar items. This may cause the seat heat-er to overheat.
NOTE Use of the seat heater for a long period of time
while the engine is not running can cause battery discharge. When cleaning the seat, do not use benzine,
paint thinner, or any similar materials.

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
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). Thecompass is now calibrated.
5. Further calibration may be necessary should out-
side. Influences cause the mirror to read inaccurate-
ly. You will know that this has occurred if your com-
pass begins to read in only limited directions.
Should you encounter this situation, return to step
one of the above procedure and recalibrate the
mirror.

WARNING
Continued operation in the position may
fog up the windows. Switch to the posi-
tion as soon as the outside dusty condition clears.
Heater operation
Defrosting or defogging the windshield
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 highestspeed.
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 but-
ton 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 out- lets, turn the corresponding knob clockwise.

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 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.
