. In freezing weather, be sure that
the wiper blades are not frozen to
the windshield or rear window
before switching on the wipers.
Attempting to operate the wiper
with the blades frozen to the
window glass could cause not
only the wiper blades to be
damaged but also the wiper mo-
tor to burn out. If the wiper
blades are frozen to the window
glass, be sure to operate the
defroster, windshield wiper dei-
cer (if equipped) or rear window
defogger before turning on the
wiper.
. If the wipers stop during opera-
tion because of ice or some other
obstruction on the window, the
wiper motor could burn out even
if the wiper switch is turned off. If
this occurs, promptly stop the
vehicle in a safe place, turn the
ignition switch to the “LOCK ”
position and clean the window
glass to allow proper wiper op-
eration.
. Use clean water if windshield
washer fluid is unavailable. In
areas where water freezes in
winter, use SUBARU Windshield
Washer Fluid or the equivalent. Refer to
“Windshield washer
fluid ”F 11-31.
Also, when driving the vehicle
when there are freezing tempera-
tures, use non-freezing type wi-
per blades.
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
NOTE. The wiper operates only when the
ignition switch is in the “ON ”or “Acc ”
position.
. The front wiper motor is protected
against overloads by a circuit breaker.
If the motor operates continuously
under an unusually heavy load, the
circuit breaker may trip to stop the
motor temporarily. If this happens, park
your vehicle in a safe place, turn off the
wiper switch, and wait for approxi-
mately 10 minutes. The circuit breaker
will reset itself, and the wipers will
again operate normally.
. Clean your wiper blades and win-
dow glass periodically with a washer
solution to prevent streaking, and to
remove accumulations of road salt or road film. Keep the washer button
depressed at least for 1 second so that
washer solution will be sprinkled all
over the windshield or rear window.
.
Grease, wax, insects or other mate-
rial on the windshield or the wiper
blade results in jerky wiper operation
and streaking on the glass. If you
cannot remove those streaks after
operating the washer or if the wiper
operation is jerky, clean the outer sur-
face of the windshield or rear window
and the wiper blades using a sponge or
soft cloth with a neutral detergent or
mild-abrasive cleaner. After cleaning,
rinse the window glass and wiper
blades with clean water. The glass is
clean if no beads form on the glass
when you rinse with water.
. If you cannot eliminate the streaking
even after following this procedure,
replace the wiper blades with new
ones. For replacement instructions,
refer to “Replacement of wiper blades ”
F 11-32.

disappears from the display (approxi-
mately two to 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.

properly and become damaged, the sys-
tem may not be able to control the interior
temperature correctly. To avoid damaging
the sensors, observe the following pre-
cautions.
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows.
– Solar sensor: beside the windshield
defroster grille.
– Interior air temperature sensor: near
the ignition switch.
– Outside temperature sensor: behind
the front grille.
Operating tips for heater and
air conditioner& Cleaning ventilation grilleAlways keep the front ventilation 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 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 conditionsUnder 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
