3-14. Wiper and Washer
NOTEThe windshield 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
location, turn off th e wiper switch, and
wait for approximately 10 minutes. The
circuit breaker will reset itself, and the
wipers will again operate normally.
 Clean your blade rubbers and
window glass periodically with a
washer solution to prevent streaking,
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 contin-
uously for more than 10 seconds,
or when the washer fluid tank is
empty. This may cause over-
heating of the washer motor.
Check the washer fluid level
frequently, such as at fuel stops. Do not operate the wipers when
the windshield is dry. This may
scratch the glass, damage the
blade rubbers and cause the
wiper motor to bu rn out. Before
operating the wiper on a dry wind-
shield always use the windshield
washer.
 In freezing weather, be sure that
the blade rubbers are not frozen
to the windshield before
switching on the wipers.
Attempting to op erate the wiper
with the blade rubbers frozen to
the window glass could cause not
only the blade rubbers to be
damaged but also might cause
the wiper motor to fail. If the blade
rubbers are frozen to the window
glass, be sure to operate the
defroster before turning on the
wiper. If the wipers stop during opera-
tion because of ice or some other
obstruction on the window, this
might cause the wiper motor to
fail even if the wiper switch is
turned off. If this occurs,
promptly stop the vehicle in a
safe location, turn the ignition
switch to the “OFF” position and
clean the window glass to allow
proper wiper operation.
 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" P366. 
Also, when driving the vehicle
when there are freezing tempera-
tures, use non-freezing type
wiper 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.

fluid from the piping between the wind-
shield washer 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.
▼ 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 accu-
mulated 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
CAUTION
Adjust the washer fluid concen-
tration appropriately for the
outside temperature. If the
concentration is inappropriate,
sprayed washer fluid may freeze
on the windshield and obstruct
your view, and the fluid may
freeze in the windshield washer
tank. State or local regulations on vola-
tile 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.
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.
CAUTION
 Do not use the parking brake
when parking for long periods in
cold weather since it could freeze
in that position. When the vehicle is parked in
snow or when it snows, raise the
wiper blades off the glass to
prevent damage to them. Under either of the following
conditions, icing may develop on
the brake system, which could
cause poor braking action.
- When the vehicle has been left
parked after use on roads
heavily covered with snow- When the vehicle has been left
parked during a snowstormCheck for snow or ice buildup on
the suspension, disc brakes and
brake hoses underneath the vehi-
cle. If there is caked snow or ice,
remove it, being careful not to
damage the disc brakes and
brake hoses and ABS harness.

If you fill the windshield washer tank with
a fluid with a different concentration from
the one used previously, purge the old
fluid from the piping between the wind-
shield washer 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.
11-24. Replacement of Wiper BladesGrease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks
after operating the windshield washer or if
the wiper operation is jerky, clean the
outer surface of the windshield using a
sponge or soft cloth with a neutral deter-
gent or mild-abrasive cleaner. Do not,
however, use detergent to clean the blade
rubbers. Use only a sponge or soft cloth
(and no neutral deterge nt or mild abrasive
cleaner) when you clean the blade
rubbers. If you wipe the rubber of the
blade strongly, the black coating compo-
nent will peel off, which will cause the
wiper to judder. Also, after wiping it off,
check that the rubber has not come loose.
After cleaning the window glass and wiper
blade rubbers, be sure to rinse them with
clean water. Rinse the window until the
water does not form beads on the glass.
This indicates that the glass is clean.
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
CAUTION
 Adjust the washer fluid concen-
tration appropriately for the
outside temperature. If the
concentration is inappropriate,
sprayed washer fluid may freeze
on the windshield and obstruct
your view, and the fluid may
freeze in the windshield washer
tank. Be careful foreign matter does
not contaminate the washer fluid
when filling the tank. Contamina-
tion could cause malfunctions,
such as clogging the pump.
 State or local regulations on vola-
tile 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.
CAUTION
 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.

WARNING
 Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and
lighters. Never expose a battery
to an open flame or electric
sparks. Batteries give off a gas
which is highly flammable and
explosive. For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery. Do not let battery fluid contact
eyes, skin, fabrics, or paint
because battery fluid is a corro-
sive acid. If battery fluid gets on
your skin or in your eyes, immedi-
ately flush the area with water
thoroughly. Seek medical help
immediately if acid has entered
the eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention
immediately.
