the blade rubbers are not frozen
to the windshield before switch-
ing on the wipers. Attempting to
operate 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 or
the windshield wiper deicer (if
equipped) 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 place, turn the ignition
switch to the“LOCK”/“OFF”po-
sition 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”F11-38.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 windshield wiper motor is pro-
tected against overloads by a circuit
breaker. If the motor operates continu-
ously 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 blade rubbers and win-
dow glass periodically with a washer
solution to prevent streaking, and to
remove accumulations of road salt or
road film. Operate the windshield
washer for at least 1 second so that
washer solution will be sprinkled all
over the windshield.
.Grease, wax, insects or other mate-rial on the windshield or the blade
rubbers 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 and the blade
rubbers using a sponge or soft cloth
with a neutral detergent or mild-abra-
sive cleaner. After cleaning, rinse the
window glass and blade rubbers 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 (or blade
rubbers) with new ones. For replace-
ment instructions, refer to“Replace-
ment of wiper blades”F11-39.

and may produce a sulfur exhaust odor or
smell. SUBARU recommends that you try
a different brand of unleaded gasoline
having lower sulfur to determine if the
problem is fuel related before returning
your vehicle to an authorized dealer for
service.
!MMT
Some gasoline contains an octane-enhan-
cing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/Mal-
function indicator light may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not be
covered by your warranty.
!Gasoline for cleaner air
Your use of gasoline with detergent ad-
ditives will help prevent deposits from
forming in your engine and fuel system.
This helps keep your engine in tune and
your emission control system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never
need to add any fuel system cleaningagents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as ethanol
(ethyl or grain alcohol) may be used in your
vehicle, but should contain no more than
10% ethanol for the proper operation of
your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from any
pump labeled E15, E30, E50 or E85 (which
are only some examples of fuel containing
more than 10% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station op-
erators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
.Fuel should be unleaded and have anoctane rating no lower than that specified
in this manual.
.Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLYif it does not exceed 5% of the fuel
mixtureANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanolEXCEPT
under these conditions.
.If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
.Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
CAUTION
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty.

Parking your vehicle
WARNING
.Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to them.
.Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
.Be sure to stop the engine if you
take a nap in the vehicle. If engine
exhaust gas enters the passen-
ger compartment, occupants in
the vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.
CAUTION
TYPE RA: When parking the vehicle,
be careful not to contact a wheel
stop, etc. Doing so may damage the
bumpers, underside of the vehicle,
etc.&Parking brake (models with-
out electronic parking brake
system)To set the parking brake, depress the
brake pedal firmly and hold it down until
