Flat Tires
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.

■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).
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 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.

9-4. Jump Starting■ Battery Precautions
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
702781
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.

Tires and Wheels
35811-21. Tires and Wheels■Types of TiresYou should be familiar with type of tires
present on your vehicle.
▼ Summer tires
The factory-installed tires on your new
vehicle are 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.
▼ 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.
▼ 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.
NOTEIf the tread wears down below 0.16 in.
(4mm) on snow tires the effectiveness
of snow tires is lost.
▼ Low profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to
use snow tires or tire chains on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.NOTELow profile tires may cause greater
damage than usual to the wheel when
receiving impact from the road sur-
face. Therefore pay attention to the fol-
lowing: 
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
 Avoid pot holes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■ Tire Pressure Monitoring
System (TPMS) (If Equipped)The tire pressure monitoring system
provides 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 monitoring system will acti-
vate 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).
If 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 pres-
sures higher than those shown on the tire
inflation pressure label. Specifically,
inflate them by an extra 1 psi (6.9 kPa,
0.07 kgf/cm
2) for every difference of 10°F

(5.6°C) between the temperature in the
garage and the temperature outside. By
way of example, the following table shows
the required tire pressures that corre-
spond to various outside temperatures
when the temperature in the garage is
60°F (15.6°C).
Example:
Tire size: 215/40R18 85Y
Standard tire pressures:
Front: 35 psi (240 kPa, 2.4 kgf/cm
2)
Rear: 35 psi (240 kPa, 2.4 kgf/cm2)
Garage temperature: 60°F (15.6°C)
Example:
Tire size: 215/45R17 87W
Standard tire pressures:
Front: 35 psi (240 kPa, 2.4 kgf/cm2)
Rear: 35 psi (240 kPa, 2.4 kgf/cm2)
Garage temperature: 60°F (15.6°C) If the low tire pressure warning light illumi-
nates when you drive the vehicle in cold

outside air after adjusting the tire pres-
sures in a warm garage, re-adjust the tire
pressures using the method described
above. Then, increase the vehicle speed
to at least 25mph (40km/h) and check to
see that the low tire pressure warning light
goes off a few minutes later. If the low tire
pressure warning light does not go off, the
tire pressure monito ring 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
between tires and the road surface
causes the tires to warm up. After illumi-
nation of the 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 go 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 replace-
ment.
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
in the instrument panel 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,
therefore, you s hould have the work
performed by a SUBARU dealer.

■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 treatment 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
unavoidable, 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 fi nd 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.
 Tires should be replaced if:
– You have tire damage such
as cuts, splits, cracks deep
enough to expose the fabric or
bulges indicating internal
damage
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 so on as possi-
ble.If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Oth-
erwise 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.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 ai r rapidly. If you
have a flat tire, re fer to "Flat Tires"
 P303.
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 possi-
ble 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.
