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.

CAUTION
Do not pull out the extension plate
with the sun visor positioned over
the windshield. The extension plate
would obstruct your view of the
rearview mirror. &
Vanity mirror with light
CAUTION
Keep the vanity mirror cover closed
while the car is being driven to avoid
being blinded by glare.
To use the vanity mirror, swing down the
sun visor and open the vanity mirror cover.
The lights beside the vanity mirror illumi-
nate when the mirror cover is opened. NOTE
Use of the vanity mirror light for a long
period of time while the engine is not
running can cause battery discharge. Storage compartment
CAUTION
. Always keep the storage com-
partment closed while driving to
reduce the risk of injury in the
event of sudden stops or anaccident.
. Do not store spray cans, contain-
ers with flammable or corrosive
liquids or any other dangerous
items in the storage compart-ment. Interior equipment

CAUTION
. Do not attempt to use a cigarette
lighter in the accessory power outlet.
. Do not place any foreign objects,
especially metal ones such as
coins or aluminum foil, into the
accessory power outlet. That
could cause a short circuit. Al-
ways put the cap on the acces-
sory power outlet when it is not
in use.
. Use only electrical appliances
which are designed for 12V DC.
The maximum power rating of an
appliance that can be connected
is 120W. Do not use an appliance
which exceeds the indicated wat-
tage for each outlet.
When using appliances con-
nected to two or more outlets
simultaneously, the total power
consumed by them must not
exceed 120W. Overloading the
accessory power outlet can
cause a short circuit. Do not use
double adapters or more than
one electrical appliance.
. If the plug on your electric appli-
ance is either too loose or too tight for the accessory power
outlet, this can result in a poor
contact or cause the plug to get
stuck. Only use plugs that fit
properly.
. Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause batterydischarge.
. Before driving your vehicle, make
sure that the plug and the cord
on your electrical appliance will
not interfere with your shifting
gears and operating the accel-
erator and brake pedals. If they
do, do not use the electrical
appliance while driving.

malfunction.
. If the rear view camera is used for
a long time while the engine is
not operated, the battery may
become completely discharged.
NOTE . Do not wipe the camera with alcohol,
benzine or paint thinner. Otherwise,
discoloration may occur. To remove
contamination, wipe the camera with a
cloth moistened with a diluted neutral
detergent and then wipe it with a soft,
dry cloth.. When waxing the vehicle, be careful
not to apply the wax to the camera. If it
comes in contact with the camera,
moisten a clean cloth with a diluted
neutral detergent to remove the wax. . The camera lens has hard coating to
help prevent scratches. However, when
washing the vehicle or cleaning the
camera lens, be careful not to scratch
the camera lens. Do not use a washing
brush directly on the camera lens. The
monitor screen may be adversely af-fected.. Strong light shined on the camera
lens may develop white light stripes
around the light source. This is not amalfunction. .
Under fluorescent light, the display
may flicker. However, this is not amalfunction.. The image of the rear view camera
may be slightly different from the
actual color of the objects.
& How to use the rear view camera
When the shift lever or select lever is set to “R ”, the rear view camera automatically
displays the rear view image from the
vehicle. When the lever is set to other
positions, the image before setting to “R ”
is displayed.
1. Set the ignition switch to “ON ”.
2. Set the shift lever or select lever to “R ”.
NOTE . For models with the genuine
SUBARU navigation system, the image
of the rear view camera has priority
over other screen displays. Therefore,
while the rear view camera is in opera-
tion, the operations of other screens
are disabled. To operate other screens,
set the shift lever or select lever to a
position other than “R ”.
. The image of the rear view camera is
horizontally reversed as is the case
with the vehicle rearview mirror or the side view mirror..
It may be difficult to see the image of
the rearview camera in the following
cases. This is not a malfunction of thecamera.
–The vehicle is in a dark place (at
night, in a tunnel, etc.). – The vehicle is in an extremely hot
or cold place.– An object (such as raindrops,
snow, dirt, etc.) that disturbs the
view of the rear view camera sticks
to the lens of the camera. – Strong light shined directly on
the camera lens (occasionally, there
are vertical lines on the screen).
