Operating tips for heater and
air conditioner
&Cleaning ventilator grille
1) Front ventilator inlet 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
Climate control/Defrosting
–CONTINUED–4-9

Climate control/Air filtration system
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 indicateany 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 steep
upgrade.
&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 (if
equipped)
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’sdust
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. For the replacement
schedule, refer to the“Warranty and
Maintenance Booklet”.
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter.
.Reduction of the airflow through
the vents.
.Windshield gets easily fogged or
misted.
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-

”button three times.
The system will honk the vehicle’s horn
each time the button is pressed.
6. The system will pause for 1 second
then honk the vehicle’s horn three times to
indicate that the service mode has been
engaged or honk one time to indicate that
the service mode has been disengaged.
NOTE
When taking your vehicle in for service,
it is recommended that you inform the
service personnel that your vehicle is
equipped with a remote engine start
system.
&Remote transmitter program
(models without“keyless ac-
cess with push-button start
system”)
New transmitters can be programmed to
the remote engine start system in the
7-20

Continuously variable trans-
mission
The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNING
Do not shift from the“P”or“N”
position into the“D”or“R”position
while depressing the accelerator
pedal. This may cause the vehicle
to lurch forward or backward.
CAUTION
.Shift into the“P”or“R”position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
.Do not race the engine for more
than 5 seconds in any position
except the“N”or“P”position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
.Do not shift from the“D”positioninto the“R”position or vice
versa until the vehicle has com-
pletely stopped. Such shifting
may cause damage to the trans-
mission.
.When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the“P”position. Do not park for
a long time with the select lever
in any other position as doing so
could result in a dead battery.
NOTE
.When the engine coolant tempera-
ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automatically
shift to the normal timing after the
engine has warmed up.
.Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the currentcondition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
.When driving under continuous hea-
vy load conditions such as towing a
camper or climbing a long, steep hill,
the engine speed or the vehicle speed
may automatically be reduced. This is
not a malfunction. This phenomenon
results from the engine control func-
tion maintaining the cooling perfor-
mance of the vehicle. The engine and
vehicle speed will return to a normal
speed when the engine is able to
maintain the optimum cooling perfor-
mance after the heavy load decreases.
Driving under a heavy load must be
performed with extreme care. Do not
try to pass a vehicle in front when
driving on an uphill slope while towing.
.The continuously variable transmis-
sion is a chain type system that
provides superior transmission effi-
ciency for maximum fuel economy. At
times, depending on varying driving
conditions, a chain operating noise
may be heard that is characteristic of
this type of system.

Jump starting
WARNING
.Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you,
thoroughly flush the exposed
area with water immediately. Get
medical help if the fluid has
entered your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and obtain immediate medical
help.
Keep everyone including chil-
dren away from the battery.
.The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.
.Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
.Whenever working on or around
a battery, always wear suitableeye protectors, and remove metal
objects such as rings, bands or
other metal jewelry.
.Be sure the jumper cables and
clamps on them do not have
loose or missing insulation.
.Do not jump start unless cables
in suitable condition are avail-
able.
.A running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away
from the cooling fan, belts and
any other moving engine parts.
Removing rings, watches and
ties is advisable.
.Jump starting is dangerous if it is
done incorrectly. If you are un-
sure about the proper procedure
for jump starting, consult a com-
petent mechanic.
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
&How to jump start
1. Make sure the booster battery is 12
volts and the negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and
accessories.
4. Connect the jumper cables exactly in
the sequence illustrated.

Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place.
&If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
&If no steam is coming from
the engine compartment
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-14.
1. Keep the engine running at idling
speed.2. Open the hood to ventilate the engine
compartment. Refer to“Engine hood”
F11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Towing
WARNING
Never tow AWD vehicles with the
front wheels raised off the ground
while the rear wheels are on the
ground, or with the rear wheels
raised off the ground while the front
wheels are on the ground. This will
cause the vehicle to spin away due
to the operation or deterioration of
the center differential.
If towing is necessary, SUBARU recom-
mends it be done by your SUBARU dealer
or a commercial towing service.
