Climate control/Operating tips for heater and air conditioner
& Efficient cooling after parking
in direct sunlightAfter 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 circuitOperate 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-
sonCheck 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 conditions 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 up a steep
incline. & Refrigerant for your climate
control system
1) Air conditioner label
Your air conditioner uses ozone friendly
refrigerant HFC134a (as shown on the air
conditioner label). Therefore, the method
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.4-10

features of the audio/visual system. Some
information may not pertain to your sys-
tem.
Your audio/visual system works when the
ignition switch is turned to the “ ACC ” or
“ ON ” position.
CAUTIONTo prevent the battery from being
discharged, do not leave the audio/
visual system on longer than neces-
sary when the engine is not running.5-12

Interior equipment/Sun visors
& Sun visor extension plate
(models with the EyeSight
system)
With the sun visor positioned over the side
window, you can use the sun visor
extension plate to prevent glare through
the gap between the sun visor and center
pillar. To use the extension plate, pull it
toward the rear of the vehicle. When you
have finished using it, stow it by pushing it
toward the front of the vehicle. CAUTIONDo not pull out the extension plate
with the sun visor positioned over
the windshield. The extension plate
would obstruct your view of the rear
view mirror. & Vanity mirror with light CAUTIONKeep the vanity mirror cover closed
while the vehicle is being driven to
avoid being temporarily blinded by
the glare of bright light.
To use the vanity mirror, swing down the
sun visor and open the vanity mirror cover.
The light beside the vanity mirror illumi-
nates 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.6-4

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 battery
discharge.
. 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.
& Use with a cigarette lighter (if
equipped) To use the accessory power outlet as a
cigarette lighter socket, purchase the
cigarette lighter plug, which is an optional
accessory. A cigarette lighter plug is
available from your SUBARU dealer.
The cigarette lighter operates only when
the ignition switch is in the “ ON ” or “ ACC ”
position.
To use the cigarette lighter, push in the
knob and wait a few moments. It will
automatically spring up when ready for
use.
WARNING
To avoid being burned, never grasp
the lighter by the end with the
heating element. Doing so could
result in injury and could also
damage the heating element.
CAUTION
. Do not hold the lighter pushed in,
because it will overheat. . The electrical power socket is
originally designed to use a gen-
uine SUBARU cigarette lighter
plug. Do not use a non-genuine
cigarette lighter plug in the sock-
et. Doing so may cause a short-
circuit and overheating, resulting
in a fire.
. If the socket is ever used for a
plug-in accessory such as a cell
phone, that may damage the
portion of the socket ’ s internal
mechanism that causes a cigar-
ette lighter plug to “ pop out ”
after its lighter element is heated.
Therefore, do not place a cigar-
ette lighter plug in a socket that
has been used, even once, to
power a plug-in accessory. Doing
so may cause the plug to stick
and overheat, creating a potential
fire hazard.Interior equipment/Accessory power outlets

of the image on the monitor is
limited, you should always check
the rear view and the surround-
ing area with your eyes and
mirrors, and move backward at
a slow speed. Moving backward
only by checking the rear view
image from the camera could
cause an accident.
. Do not disassemble or modify the
camera, switch or wiring. If
smoke comes out or you smell
a strange odor, stop using the
rear view camera immediately.
Contact your SUBARU dealer
for an inspection. Continued use
may result in accident, fire or
electric shock.
CAUTION
. If your vehicle is washed with a
high-pressure washer, do not
allow water to contact the camera
directly. Entry of water into the
camera lens may result in con-
densation, malfunction, fire or
electric shock.
. Since the camera is a precision
device, do not subject it to strong
impacts. Otherwise, malfunction, fire or electric shock may occur.
. If mud or snow sticks to or is
frozen on the camera, you must
be very careful when removing it.
Otherwise, damage to the camera
may cause a fire or electric
shock. Pour water or lukewarm
water over the camera to remove
mud and ice, and wipe it with a
soft, dry cloth.
. Do not put a flame close to the
camera or wiring. Otherwise, da-
mage or fire may occur.
. When replacing the fuse, be sure
to use a fuse with the specified
rating. Use of a fuse with a
different rating may result in a
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 a 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 image quality of the rear view
camera may deteriorate.
. Strong light shined on the camera
lens may develop vertical lines around
the light source. This is not a malfunc-
tion.
. Under fluorescent light, the display
may flicker. However, this is not a
malfunction.
. 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/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 ”Interior equipment/Rear view camera
