2010 SUBARU LEGACY air conditioning

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

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.

Air filtration system
Your vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule shown in the
following table. This schedule should be
followed to maintain the filter ’s dust
collection ability. Under extremely dusty
conditions, the filter should be replaced
more frequently. Have your filter checked
or replaced by your SUBARU dealer. For
replacement, use only a genuine
SUBARU air filter kit.
Replacement schedule: Every 15 months or 15,000 miles (24,000
km) whichever comes first
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter. . Reduction of the air flow through
the vents.
. Windshield gets easily fogged or
misted. NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained. &
Replacing an air filter
1. Remove the glove box. (1) Open the glove box.
(2) Remove the damper shaft from the
glove box.
(3) Pull out the glove box.
2. Remove the cover of the air filter. Climate control

Transmitter flash sequence Feature description
Flashes when button is pressed Indicates that the system is transmitting an RF signal.
Two long flashes following re-
mote start activation (transmit-
ter button is pressed two times
within 3 seconds) Indicates that the transmitter did not receive the remote start
activation confirmation from the vehicle system. The transmitter
will automatically send one additional remote start activation
attempt. This usually occurs when the operational range is at its
limit or has been exceeded.
One flash following remote
start activation (transmitter
button is pressed two times
within 3 seconds) Indicates that the engine is running via remote start. If the
transmitter is moved outside of the operating range of the
system, this sequence will timeout after the normal 15-minute
vehicle run cycle.
2 flashes every 5 seconds Indicates that the engine is running via remote start. If the
transmitter is removed outside of the operating range of the
system, this sequence will timeout after the normal 15-minute
vehicle run cycle.
3 flashes Indicates that the engine has turned off due to a remote start
system 15-minute timeout, vehicle safety parameter or normal shutdown. &
Entering the vehicle follow-
ing remote engine start shut- down
An alarm trigger may occur if the vehicle is
opened by the remote keyless entry
transmitter within a few seconds immedi-
ately following remote engine start shut-down. & Pre-heating or pre-cooling
the interior of the vehicle
Models with automatic climate control system:
After the system starts the engine, the
automatic climate control system will
activate the “FULL AUTO ”mode and heat
or cool the interior to the predetermined
median (room) temperature. No pre-
setting of controls is necessary.
Models with manual climate control system:
Before exiting the vehicle, set the tem-
perature controls to the desired setting
and operation. After the system starts the
engine, the heater or air conditioning will
activate and heat or cool the interior to
your setting. Starting and operating
