considerable speed and force
and can injure or even kill chil-
dren, especially if they are not
restrained or improperly re-
strained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater.
For that reason, we strongly
recommend that ALL children
(including those in child seats
and those that have outgrown
child restraint devices) sit in the
REAR seat properly restrained at
all times in a child restraint
device or in a seatbelt, whichever
is appropriate for the child ’ s age,
height and weight.
Secure ALL types of child re-
straint devices (including for-
ward facing child seats) in the
REAR seats at all times.
According to accident statistics,
children are safer when properly
restrained in the rear seating
positions than in the front seat-
ing positions.
For instructions and precautions
concerning the child restraint
system, refer to “ Child restraint
systems ” F 1-21. . NEVER INSTALL A FORWARD
OR REARWARD FACING CHILD
SEAT IN THE FRONT SEAT.
DOING SO RISKS SERIOUS IN-
JURY OR DEATH TO THE CHILD
BY PLACING THE CHILD ’ S HEAD
TOO CLOSE TO THE SRS AIR-
BAG.
. Never allow a child to stand up,
or to kneel on the front passen-
ger ’ s seat, or never hold a child
on your lap or in your arms. The
SRS airbag deploys with consid-
erable force and can injure or
even kill the child.
CAUTION. When the SRS airbag deploys,
some smoke will be released.
This smoke could cause breath-
ing problems for people with a
history of asthma or other
breathing trouble. If you or your
passengers have breathing pro-
blems after SRS airbag deploys,
get fresh air promptly. . A deploying SRS airbag releases
hot gas. Occupants could get
burned if they come into direct
contact with the hot gas.
NOTE . When you sell your vehicle, we urge
you to explain to the buyer that it is
equipped with SRS airbags by alerting
the buyer to the applicable section in
this Owner ’ s Manual.
. If the SRS airbag deploys, fuel
supply will be cut off to reduce the risk
of fire caused by leaking fuel. For
details about restarting of the engine,
refer to “ If your vehicle is involved in
an accident ” F 9-18.Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)

Wiper and washer WARNINGIn 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
might cause the wiper motor to
fail. 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 might cause
the wiper motor to fail. If the
wiper blades are frozen to the
window glass, be sure to operate
the defroster, windshield wiper
deicer (if equipped) or rear win-
dow defogger 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 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 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 wiper blades 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 Instruments and controls/Wiper and washer

Starting and operating/Fuel
! MMT
Some gasoline contains an octane-en-
hancing additive called MMT (Methylcy-
clopentadienyl 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
additives 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 cleaning
agents 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 MTBE
(Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in your vehicle, but should contain no more
than 15% MTBE or 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
operators 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 an
octane 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
ONLY if it does not exceed 5% of the fuel
mixture AND if 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 methanol EXCEPT
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.
CAUTIONDo 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.7-4
