To remove:
While pressing the release button, pull out
the head restraint.
To install:
Install the head restraint into the holes that
are located on the top of the seatback until
the head restraint locks.
WARNING
. Never drive the vehicle with the
head restraints removed because
they are designed to reduce the
risk of serious neck injury in the
event that the vehicle is struck
from the rear. Therefore, when
you remove the head restraints,
you must reinstall all head re-
straints to protect vehicle occu-pants.
. All occupants, including the dri-
ver, should not operate a vehicle
or sit in a vehicle ’s seat until the
head restraints are placed in their
proper positions in order to mini-
mize the risk of neck injury in the
event of a collision. Seat heater (if equipped)
1)
HIGH –Rapid heating
2) LOW –Normal heating
3) OFF –Off
A) Left-hand side
B) Right-hand side The seat heater operates when the igni-
tion switch is either in the
“Acc ”or “ON ”
position.
To turn on the seat heater, press the “ LOW ”or “HIGH ”position on the switch,
as desired, depending on the tempera-ture.
Selecting the “HIGH ”position will cause
the seat to heat up quicker.
To turn off the seat heater, slightly press
the opposite side of the current position.
The indicator located on the switch illumi-
nates when the seat heater is in operation.
When the vehicle ’s interior is warmed
enough or before you leave the vehicle,
be sure to turn the switch off.
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. Rear seats
WARNING
Seatbelts provide maximum re-
straint when the occupant sits well
back and upright in the seat. Do not
put cushions or any other materials
between occupants and seatbacks
or seat cushions. If you do so, the
risk of sliding under the lap belt and
of the lap belt sliding up over the
abdomen will increase, and both can
result in serious internal injury ordeath.
WARNING
Never stack luggage or other cargo
higher than the top of the seatback
because it could tumble forward and
injure passengers in the event of a
sudden stop or accident. Seat, seatbelt and SRS airbags

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 duringreversing. !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. !
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 metallic 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 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 (approxi-
mately two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary
should outside 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 recali-
brate the mirror. !
Compass zone adjustment
1. The zone setting is factory preset to
Zone 8. Refer to the “Compass calibration
zone ”map 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 appear 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 cycling when the
correct zone setting for your location isdisplayed.
4. Releasing the button for 3 seconds will
exit the zone setting mode. Instruments and controls

sor automatically operates to quickly
defog the windshield. However the
indicator on the air conditioner button
will not illuminate. At the same time,
the air inlet selection is automatically
set to “outside air ”mode.
. Warm air also comes out from the
right and left air outlets. To stop warm
air flow from these outlets, turn the
corresponding wheel to the “
”posi-
tion. ! Defrosting or defogging the wind- shield
To direct warm air to the windshield and
front door windows:
1. Set the air inlet selection button to the
OFF position.

Operating tips for heater and
air conditioner &Cleaning ventilator grille
Always keep the front ventilator 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 condition
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 system.
& Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steepupgrade. & Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od 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.
