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.

should be checked daily, weekly or at
fuel stops.
7-4. Starting and Stopping Engine■Safety PrecautionsRefer to "Safety Precautions"  P94.■Operating Range for Push-
Button Start SystemRefer to "Operating Range for Push-
Button Start System" P125.■ General Precautions When
Starting Engine
NOTEIt may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This
difficulty is caused by the electroni-
cally controlled throttle’s self-diag-
nosis function. To overcome it, keep
the ignition switch in the “ON” position
for approximately 10 seconds before
starting the engine.
 Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
 After the engine starts, the engine
speed will be kept high.
CAUTION
Small animals trapped in the cool-
ing fan and belt of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
WARNING
Never start the engine from
outside the vehicle. It may result
in an accident. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide
poisoning.
 Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
 If the engine is stopped during
driving, the catalyst may overheat
and burn. When starting the engine, be sure
to sit in the driver’s seat.

Driving Tips8
– CONTINUED –
8-8. 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 afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that
contains an antifr eeze solution. Do not
use engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
If you fill the windshield washer tank with
a fluid with a different concentration from
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.-Ride-Handling- Braking- Speedometer/Odometer cali-
bration- Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
 In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a
seat belt. The driver and all your
passengers should fasten their
seatbelts before st arting to drive
in order to minimize the chance of
serious injury or death. Do not make sharp turns or quick
maneuvers unless absolutely
unavoidable. Such actions are
dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
 Whenever strong crosswinds are
present, slow do wn sufficiently to
maintain control of your vehicle. Never to drive through pools and
puddles, or roads flooded with
water. Water entering the engine
air intake or the exhaust pipe or
water splashing onto electrical
parts may damage your vehicle
and may cause it to stall. In this
case, contact your SUBARU
dealer immediat ely. Regardless
of its depth, it can wash away the
ground from under your tires,
resulting in possible loss of trac-
tion and even vehicle rollover.
CAUTION
After driving on gravel roads or
rough roads, check the undercar-
riage of the vehicle body for any
damage, deformation, or paint
removal. If you notice any irregulari-
ties, contact a SUBARU dealer for
an inspection as soon as possible.

Winter Driving
294the 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.
▼ 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.

Alloy Wheels
366NOTEWhen any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000
km). If any nut is loos e, tighten it to the
specified torque.
11-22. Alloy WheelsAlloy wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
 When any of the wheels is removed
and replaced for tire rotation or to change
a flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
 Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
 Never let the wheel rub against sharp
protrusions or curbs.
 When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
11-23. Windshield Washer Fluid1) “LOW” positionThe washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge. 
If the level falls below the second hole
from the bottom (the “LOW” position), add
washer fluid.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing
during turns. The resulting loss of
vehicle control could lead to an
accident.

Replacement of Wiper Blades
367
Maintenance and Service11
– CONTINUED –
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.
