308Do not use tire chains on a sealed
tire.Do not tow a trailer.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant.Safely park your vehicle on the
roadside so that you do not
obstruct the flow of traffic and so
that you are able to seal the flat
tire without being in danger.Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the
vehicle will not move.Stop the engine before sealing
the flat tire.Turn on the hazard warning
flasher while sealing the flat tire.Do not attempt to remove foreign
objects like nails or screws that
have penetrated the tire. Leave
them as they are. Never leave the flat tire repair kit
unattended while in use.Only one tire can be repaired with
one bottle of sealant.
The tires can be repaired when
the ambient temperature is −22 °F
( − 30 °C) or higher.
CAUTION
 Remember that the flat tire repair
kit only provides temporary
mobility. Regulations concerning
tire repair after usage of flat tire
repair kit may di ffer from country
to country. We recommend that
you consult your SUBARU dealer
or tire dealer for advice. Store the flat tire repair kit safely
and secure it under the floor of
the trunk. Storing it anywhere in
the passenger compartment is
not advisable because it could
strike an occupant in the event of
a sudden stop or collision and
cause injury. Use the flat tire repair kit with
original vehicle tires only.Do not keep the air compressor
operating for more than 10
minutes, otherwise there is a risk
of overheating.The temperature of the air
compressor may become high.
Be careful not to burn yourself.
When raining, take measures to
prevent the air compressor from
being exposed directly to the
rain. Exposing to rain may cause
a malfunction.Do not use air compressors other
than the one in the repair kit.
Using an air compressor other
than the one in the repair kit may
damage the tires.Do not disassemble or modify the
air compressor to enable the use
of a power supply or a battery
other than DC 12 V.If a temporary puncture repair is
performed with the repair kit, the
Tire Pressure Monitoring System
(TPMS) (if equipped) may not
operate normally.

How to seal the flat tire
To seal the flat tire, perform the following
steps.
 First, pump in the sealant and air. Drive
the vehicle for approximately 10 minutes or 3 miles (5 km) so that the sealant can
seal the damaged area.

Stop the vehicle again, check and, if
necessary, adjust the pressure of the
damaged tire.
 After that, you can continue to drive
carefully no faster than 50 mph (80 km/h)
and within the maximum distance of 125
miles (200 km).
Inform all other users of the vehicle that
the tire has been temporarily sealed with
the flat tire repair kit and make them aware
of the special driving conditions to be
observed.
WARNING
 Do not drink the sealant. If the
sealant is accidentally swal-
lowed, seek medical attention
immediately.If the sealant splashes onto your
skin or eyes, wash it away imme-
diately with plen ty of water. If
necessary, seek medical atten-
tion immediately. Keep the flat tire repair kit out of
the reach of children.

312outlet. Apply the parking brake and turn on
the ignition switch to the “ACC” position.Turn the air compressor switch on and
adjust the air pressure to the appropriate
level (green zone of the air gauge).
NOTEAfter the compressor starts to
operate, the air pressure will tempo-
rarily rise to 45 psi (300 kPa, 3.0 kgf/
cm
2) or higher. After about 30 seconds
when all of the sealant is inside the tire,
the air pressure will lower, repre-
senting the air pressure in the tire.
 In extremely low temperatures −22°F
to −4°F ( −30°C to − 20°C), the viscosity
of the sealant increases and the
sealant will flow more slowly. In such
temperatures, bring the sealant into
the vehicle to warm it up before use.
 When mending the tire, if the air
pressure gauge is hard to read, turn
the compressor switch off once to get
an accurate reading. 5. While filling the tire with air, attach the
speed limit label on the position shown in
the illustration.

CAUTION

Do not run the air compressor for
more than 10 minutes as it can
get hot. Be careful not to get
burned.If tire pressure doesn’t reach the
green zone for 10 minutes, this kit
will be unable to seal the tire.
Please contact your SUBARU
dealer for help.
WARNING
Do not attach the speed limit label
in a position where the label hides
the warning lamp or on the steering
wheel. It may interfere with the nor-
mal operation of the airbag and lead
to a critical failure.

6. Turn the air compressor power switch
off when the air pressure reaches the
green zone of the air gauge.
Remove the power plug from the acces-
sory power socket.
Remove the hose after filling the tire with
air and fasten the valve cap. Connect the hose of the bottle to the valve
of the bottle in a circular fashion to avoid
leakage of the remaining sealant.
7. Stow the kit back in the vehicle and
drive your vehicle immediately for 10
minutes or 3 miles (5 km).

Tire Pressure Monitoring
System (TPMS) (If Equipped)Low tire pressure warning lightThe tire pressure monitoring system
provides the driver with the warning
message indicated by sending a signal
from a sensor that is installed in each
wheel when tire pressure is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven.
Also, this system may not react immedi-
ately to a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
702780
WARNING
 If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
Otherwise an accident involving
serious vehicle damage and
serious personal injury could
occur.
(1) Keep driving straight ahead
while gradually reducing
speed.(2) Slowly pull off the road to asafe place.(3) Check the pressure for allfour tires and adjust the pres-
sure to the CO LD tire pres-
sure shown on the vehicle
placard on the center pillar on
the driver’s side.If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, replace it
with a spare tire as soon as pos-
sible.
 When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately one minute.
This indicates the TPMS is unable
to monitor all four road wheels.
Contact your SUBARU dealer as
soon as possible for tire and
sensor replacement and/or
system resetting.When a tire is repaired with liquid
sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid
sealant is used, contact your
nearest SUBARU dealer or other
qualified service shop as soon as
possible. Make sure to replace
the tire pressure warning valve
and transmitter when replacing
the tire. You may reuse the wheel
if there is no damage to it and if
the sealant residue is properly
cleaned off.
If the light illuminates steadily
after blinking for approximately
one minute, promptly contact a
SUBARU dealer to have the sys-
tem inspected.

WARNING
 Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you, thor-
oughly flush the exposed area
with water immedi ately. Get med-
ical help if the fluid has entered
your eyes.If battery fluid is accidentally
swallowed, imme diately drink a
large amount of milk or water,
and obtain immediate medical
help.Keep everyone including chil-
dren away from the battery.
 The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
Whenever working on or around a
battery, always wear suitable eye
protectors, and remove metal
objects such as rings, bands or
other metal jewelry.Be sure the jumper cables and
clamps on them do not have
loose or missing insulation.Do not jump start unless cables in
suitable condition are available.A running engine can be
dangerous. Keep your fingers,
hands, clothing, hair and tools
away from the cooling fan, belts
and any other moving engine
parts. Removing rings, watches
and ties is advisable.Jump starting is dangerous if it is
done incorrectly. If you are
unsure about the proper proce-
dure for jump starting, consult a
competent mechanic.
