NOTEContact a SUBARU dealer when jack-
ing up the vehicle using a garage jack.
1. Park on a hard, level surface, when-
ever possible, then stop the engine.
2. Set the parking brake securely and
shift the shift lever in reverse (MT models)
or the select lever to the “P” (Park) posi-
tion (AT models).
3. Turn on the hazard warning flasher
and unload all occupants and luggage
from the vehicle.
4. Put wheel blocks at the front and rear
of the tire diagonally opposite the flat tire. 5. Take out the jack, jack handle and

wheel nut wrench.
The tools and the spare tire are stored
under the floor of the trunk. Refer to
"Maintenance Tools" P302.
NOTEMake sure that the jack is well lubri-
cated before using it.
6. Models with spare tire: Take out the
under-floor storage compartment and turn
the attaching bolt counterclockwise, then
take the spare tire out.
 Always turn off the engine before
raising the flat tire off the ground
using the jack. Never swing or
push the vehicle supported with
the jack. The jack can come out of
the jacking point due to a jolt and
this can result in serious injury or
death. All passengers must exit the
vehicle before you raise it with
the jack. Raising the vehicle with
someone inside of it could result
in serious injury or death. Do not start the vehicle while it is
supported by the jack. Doing so
could result in serious injury or
death.
CAUTION
Do not hit and bend the disc rotor
backing plate when removing and
installing the tire. A bent backing
plate may scrape against the disc
rotor and cause noise while the
vehicle is in motion.

– CONTINUED –
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.

 Do not run the air compressor for
more than 10 minutes as it can
get hot. Be care ful 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

■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 mo nitoring 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).

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 a
safe place.(3) Check the pressure for all
four 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.
