Wiper and washer
WARNING
In freezing weather, do not use the
windshield washer until the wind-
shield is sufficiently warmed by the
defroster.
Otherwise the washer fluid can
freeze on the windshield, blocking
your view.
CAUTION
. Do not operate the washer con-
tinuously for more than 10 sec-
onds, or when the washer fluid
tank is empty. This may cause
overheating of the washer motor.
Check the washer fluid level
frequently, such as at fuel stops.
. Do not operate the wipers when
the windshield or rear window is
dry. This may scratch the glass,
damage the wiper blades and
cause the wiper motor to burn
out. Before operating the wiper
on a dry windshield or rear
window, always use the wind-
shield washer.

. 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 11-38.
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 11-39.

vated.
To turn them off, push the control switch
again. They also turn off when the ignition
switch is turned to the “Acc”or “LOCK”
position.
The defogger and deicer system will
automatically shut off after approximately
15 minutes. If the rear window and the
outside mirrors have been cleared and the windshield wiper blades have been deiced
completely before that time, push the
control switch to turn them off. If defrost-
ing, defogging or deicing is not complete,
you have to push the control switch to turn
them on again.

Driving tips
Winter driving& Operation during cold
weatherCarry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen,
use hot water to melt the ice, and after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.
Washer Fluid Con-
centration Freezing Temperature
30% 10.4 8F( 12 8C)
50% 48F( 20 8C)
100% 49
8F( 45 8C)In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block the
nozzles.
CAUTION
.
Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.

! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe
winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
! Parking in cold weather
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, you should observe the following
tips.
1. Place the shift lever in “1 ” or “R”for MT
models, or the select lever in “P”for AT
models.
2. Use tire stops under the tires to
prevent the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them. When the vehicle has been left parked
after use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the
brake system, which could cause poor
braking action. Check for snow or ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-
ness.
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
! Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty. If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity.
&
Driving on snowy and icy
roadsTo prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’s braking perfor-
manceonsnowyandicyroads.For
information on braking on slippery sur-
faces, refer to “ABS (Anti-lock Brake
System) ”F 7-32 and “Vehicle Dynamics
Control system ”F 7-34.

Driving tips
roads. This may cause loss of
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the front wiper blades are frozen to the
windshield, use the defroster with the
airflow control dial in the “
”position
and the temperature control dial set for
maximum warmth until the wiper blades
are completely thawed out. For details,
refer to the following section.
. For the manual climate control system,
refer to “Defrosting or defogging the
windshield ”F 4-5.
. For the automatic climate control sys-
tem, refer to “Control panel ”F 4-8.
If your vehicle is equipped with a wind-
shield wiper deicer, it is helpful to thaw the windshield wiper blades. Refer to
“Defog-
ger and deicer ”F 3-48.
If the rear wiper blade is frozen to the rear
window, use the rear window defogger.
Refer to “Defogger and deicer ”F 3-48.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow control dial in “
”and the
temperature control dial set for maximum
warmth. After the windshield gets warmed
enough to melt the frozen snow on it,
wash it away using the windshield washer.
Refer to “Washer”F 3-39.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.
CAUTION
During high-speed driving, non- freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the
vehicle speed.
NOTEWhen the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.&
Corrosion protectionRefer to “Corrosion protection ”F 10-4.& Snow tires
WARNING
. When replacing original tires with
winter (snow) tires, make sure
you use only the same size,
construction and load range as
the original tires listed on the tire
placard. Using other sizes and
construction may affect speed-
ometer/odometer calibration and
clearance between the body and
tires. It also may be dangerous
and lead to loss of vehicle con-
trol.
. You must install four winter tires
