If the tire is punctured, you can seal the
flat tire temporarily by using the flat tire
repair kit. You can seal a flat tire caused,
for example, by nails or similar objects
with less than 0.2 in (4 mm). However,
depending on the type and extent of tire
damage, some tires can only be partially
sealed or not sealed at all, and this condi-
tion may cause a loss of tire pressure. A
loss of tire pressure can affect vehicle
handling, leading to the loss of vehicle
control.
After sealing the flat tire temporarily,
change the tires with new ones as soon as
possible. We recommend that you have
the sealed tire changed by your nearest
SUBARU dealer. You may reuse the
wheel if the attached sealant is wiped off,
but the valve of the wheel must be
replaced with a new one. If you reuse the
wheel without replacing the valve, air may
leak from the valve. For tire replacement, refer to "Tire

Replacement" P365.
▼ Safety precautions when sealing a
flat tireObserve the following rules when sealing
a flat tire.1) Sealing is possible
2) Sealing is not possible
Compliance with these instructions
is vital to ensuring vehicle safety.
Noncompliance with these instruc-
tions means risking tire damage,
which can affect vehicle handling
and lead to loss of vehicle control.
This may result in serious injury or
death.
WARNING
 Do not use the flat tire repair kit in
the following cases.
- The tire has already been
damaged as a result of being
driven in the under inflated
condition.

- The tire damage is not located
within the visible tread of the
tire.- The tire damage is on the
sidewall of the tire.- When the tire has been taken
off of the wheel.- The wheel or the tire valve of
the flat tire is damaged.- Two or more tires have been
punctured.- The expiration date of the
sealant has passed.- The tire is punctured by
pointed items such as nails of
0.2 in (4 mm) or larger.
 When inflating the flat tire, if the
tire inflation pressure does not
reach the green zone of the pres-
sure gauge within 10 minutes, do
not continue to seal the tire. We
recommend that you contact your
SUBARU dealer. Drive with caution and avoid
making sudden steering or
driving maneuvers. Do not exceed a maximum speed
of 50 mph (80 km/h). Do not exceed a maximum
driving distance of 125 miles (200
km).

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 tireTo 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.
