compressor into the accessory power
outlet. Apply the parking brake and turn
on the ignition switch to the“ACC”position.Apply the parking brake and turn on the
ignition switch to the“ACC”position. Turn
the air compressor switch on and adjustthe air pressure to the appropriate level
(green zone of the air gauge).
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.NOTE.After the compressor starts to oper-
ate, the air pressure will temporarily
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, representing the air
pressure in the tire.
.In extremely low temperatures228F
to48F(308Cto208C), the viscosity
of the sealant increases and the sealant
will flow more slowly. In such tempera-
tures, 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 anaccurate reading.
5. While filling the tire with air, attach the
speed limit label on the position shown in
the illustration.
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
normal 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 withair 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.
CAUTION
The sealant may stain clothing.

drive your vehicle immediately for 10
minutes or 3 miles (5 km).
WARNING
.Drive carefully. Do not exceed 50
mph (80 km/h). Driving faster
than that can result in the vehicle
shaking.
.Do not use tire chains on a sealed
tire.
.Do not tow a trailer.
.If heavy vibrations, unsteady
steering behavior or noises oc-
cur while driving, reduce your

tire and its pressure. If the tire
pressure is in the red zone of the
air gauge or if there are any
cracks, bumps or similar tire
damage visible, temporary re-
pairs cannot be performed with
the repair kit. We recommend that
you consult with your SUBARU
dealer or road service provider.
8. After driving for 10 minutes or 3 miles
(5 km), whichever comes first, stop the
vehicle in a safe place to recheck the air
pressure (see step 4).
If necessary, fill the tire with air to the
appropriate air pressure again and drive
carefully to the nearest SUBARU dealer
for tire, valve stem and sealant bottle
replacement.
NOTEConnect the air compressor only to the
tire valve.
CAUTION
.If the air pressure is in red zone of
the air gauge, the kit did not
successfully seal the puncture.
In this case, please stop driving
and contact your SUBARU dealer
for help.
.Do not drive your vehicle with the
sealed tire for more than 125
miles (200 km). Failure to replace
the valve stem may result in air
leakage at the valve stem.
Before the tire is removed from the rim,
inform your SUBARU dealer or other tire
dealer that the tire contains sealant.
CAUTION
The sealant bottle and speed limit
label need to be replaced after using
the flat tire repair kit.NOTENew sealant and replacement parts can
be purchased from your authorizedrepair shop or SUBARU dealer, and
they should also be installed into the kit
by a specialist. Empty sealant bottles
and replacement parts must be re-
turned to your SUBARU dealer or
disposed of in compliance with local
waste disposal regulations.

&Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)Low tire pressure warning lightThe tire pressure monitoring system pro-
vides 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).
WARNING
.If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place. Otherwise an acci-
dent involving serious vehicle
damage and serious personal
injury could occur.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door 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, refer to“Flat
tires”F9-5.
.When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the lowtire 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 sys-
tem resetting.
.When a tire is repaired with liquid
sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid sea-
lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. 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.

hole until its thread can no longer be seen.4. Tighten the towing hook securely using
the wheel nut wrench.
After towing, remove the towing hook fromthe vehicle and stow it in the tool bucket.
Fit the towing hook cover on the bumper.
WARNING
Do not use the towing hook except
when towing your vehicle.
Be sure to remove the towing hook
after towing. Leaving the towing
hook mounted on the vehicle could
interfere with proper operation of
the fuel pump shut off function when
the vehicle is struck from behind.
CAUTION
To prevent deformation to the bum-
per and the towing hook, do not
apply an excessive load to the tow-
ing hook.Front tie-down hooks:
The front tie-down hooks are located
between each of the front tires and the
front bumper.

Parking brake stroke (models
without electronic parking
brake system)Check the parking brake stroke according
to the maintenance schedule in the“War-
ranty and Maintenance Booklet”.
When the parking brake is properly ad-
justed, braking power is fully applied by
pulling the lever up 7 to 8 notches gently
but firmly (approximately 45 lbf [200 N,
20.4 kgf]). If the parking brake lever stroke
is not within the specified range, have the
brake system checked and adjusted at
your SUBARU dealer.
Tires and wheels&Types of tiresYou should be familiar with type of tires
present on your vehicle.
!All season tires
All season tires are designed to provide an
adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads.
All season tires are identified by“ALL
SEASON”and/or“M+S”(Mud & Snow) on
the tire sidewall.
!Summer tires
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving on
slippery roads such as on snow-covered or
icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires.!Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
&Tire pressure monitoring
system (TPMS) (if equipped)The tire pressure monitoring system pro-
vides the driver with a warning message by
sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the
vehicle is driven. Also, this system may not
react immediately to a sudden drop in tire
pressure (for example, a blow-out caused
by running over a sharp object).

Low tire pressure warning lightIf you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to
pressures higher than those shown on
the tire placard. Specifically, inflate them
by an extra 1 psi (6.9 kPa, 0.07 kgf/cm
2) for
every difference of 108F (5.68C) between
the temperature in the garage and the
temperature outside. By way of example,
the following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 608F (15.68C).Example:
Tire size: 245/40R18 97W
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm
2)
Rear: 32 psi (220 kPa, 2.2 kgf/cm2)
Garage temperature: 608F (15.68C)

108F(238C) 40 (275, 2.75)39 (270, 2.7)
If the low tire pressure warning light
illuminates when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light
turns off a few minutes later. If the low tire
pressure warning light does not turn off,
the tire pressure monitoring system may
not be functioning normally. In this event,
go to a SUBARU dealer to have the
system inspected as soon as possible.
While the vehicle is driven, friction be-
tween tires and the road surface causes
the tires to warm up. After illumination ofthe low tire pressure warning light, any
increase in the tire pressures caused by an
increase in the outside air temperature or
by an increase in the temperature in the
tires can cause the low tire pressure
warning light to turn off.
System resetting is necessary when the
wheels are changed (for example, a switch
to snow tires) and new TPMS valves are
installed on the newly fitted wheels. Have
this work performed by a SUBARU dealer
following wheel replacement.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
on the combination meter will illuminate
steadily after blinking for approximately
one minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.

WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-
ble.
If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Other-
wise an accident involving serious
vehicle damage and serious perso-
nal injury could occur.
1) Keep driving straight ahead while
gradually reducing speed.
2) Slowly pull off the road to a safe
place.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, refer to“Flat tires”F9-5.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-sure warning light will illuminate
steadily after blinking for approxi-
mately 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. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
&Tire inspectionCheck on a daily basis that the tires are
free from serious damage, nails, and
stones. At the same time, check the tires
for abnormal wear.
Contact your SUBARU dealer immediately
if you find any problem.NOTE.When the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
that cannot be seen with the naked eye.
This type of damage does not become
evident until time has passed. Try not to
drive over curbs, potholes or on other
rough surfaces. If doing so is unavoid-able, keep the vehicle’s speed down to
a walking pace or less, and approach
the curbs as squarely as possible. Also,
make sure the tires are not pressed
against the curb when you park the
vehicle.
.If you feel unusual vibration while
driving or find it difficult to steer the
vehicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized
SUBARU dealer and have the vehicle
inspected.
&Tire pressures and wearMaintaining the correct tire pressures
helps to maximize the tires’service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) and before any long
journey.
