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 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 steep
upgrade.
&Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFO-1234yf. Therefore, the
method of adding, changing or checking
the refrigerant is different from the method
for CFC12 (freon) or HFC134a. Consult
your SUBARU dealer for service. Repairs
needed as a result of using the wrong
refrigerant are not covered under war-
ranty.
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-

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) Push both sides of the glove box
inward to unlock the stoppers and then
pull down the glove box as far as it will
go.
(4) Pull out the glove box horizontally
and remove the hinge portion. When doing this, be careful not to damage
the hinge.
2. Remove the cover of the air filter.
3. Remove the air filter according to the
following procedure in order to prevent
