properly. If there is no problem and all tires
are properly inflated, the light will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pres-
sure label, you should determine the
proper inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’ s handling and
stopping ability. Please note that the
TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s respon-
sibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale.
The TPMS gives warning both when a tire
is significantly under-inflated and when
there is a problem in the TPMS. The low
tire pressure warning light operates differ-
ently according to these conditions as
follows:
When a tire is significantly under-
inflated:
Steady illumination
When there is a problem in the TPMS:
Flashing
Should the warning light flash, have the
system inspected by your nearest
SUBARU dealer as soon as possible.
WARNING
If this light does not come on briefly
after the ignition switch is turned ON
or the light is flashing, you should
have your Tire Pressure Monitoring
System checked at a SUBARU deal-
er as soon as possible.
If this light comes on while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
If this light still comes on 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, replace it with a spare tire
as soon as possible.
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 flash. This
indicates the TPMS is unable to
monitor all four road wheels. Con-
tact your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light flashes, promptly contact a
SUBARU dealer to have the system
inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32

In case of emergency
If you park your vehicle in an
emergencyThe hazard warning flasher should be
used in day or night to warn other drivers
when you have to park your vehicle under
emergency conditions.
Avoid stopping on the road. It is best to
safely pull off the road if a problem occurs.
The hazard warning flasher can be acti-
vated regardless of the ignition switch
position.
Turn on the hazard warning by pushing
the hazard warning flasher switch. Turn it
off by pushing the switch again.
NOTEWhen the hazard warning flasher is on,
the turn signals do not work.
Temporary spare tire
WARNING
. Never tow a trailer when the
temporary spare tire is used.
The temporary spare tire is not
designed to sustain the towing
load. Use of the temporary spare
tire when towing can result in
failure of the spare tire and/or
less stability of the vehicle and
may lead to an accident.
. 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
flash. This indicates the tire
pressure monitoring system
(TPMS) is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as pos-
sible for tire and sensor replace-
ment and/or system resetting.

stop or collisions, loose equipment
could strike occupants and cause
injury. Store the tire and all tools in
the proper place.& Tire pressure monitoring
system (TPMS) (if equipped)The 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 running over
a sharp object).
WARNING
If the low tire pressure warning light
comes on while driving, never brake
suddenly and keep driving straight
ahead while gradually reducing
speed. Then slowly pull off the road
to a safe place. Otherwise an acci-
dent involving serious vehicle da-
mage and serious personal injury
could occur.
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 comes
on while driving after adjusting the
tire pressure, a tire may have sig-
nificant 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 possible.
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 flash. This
indicates the TPMS is unable to
monitor all four road wheels. Con-
tact your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors.
If the light flashes, promptly contact
a SUBARU dealer to have the sys-
tem inspected.

If the low tire pressure warning light
comes on 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
goes off a few minutes later. If the low tire
pressure warning light does not go 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 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 flash.
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 come on briefly after the
ignition switch is turned ON or the
light is flashing, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
If this light comes on while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.

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

Maintenance and service
a flat tire, replace it with a spare tire
as soon as possible.
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 flash. This
indicates the TPMS is unable to
monitor all four road wheels. Con-
tact your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light flashes, 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 immedi-
ately 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
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 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.
Check the tire pressures when the tires
are cold. Use a pressure gauge to adjust
the tire pressures to the values shown on
the tire placard. The tire placard is located
on the door pillar on the driver ’s side.
Driving even a short distance warms up
the tires and increases the tire pressures.
Also, the tire pressures are affected by the
outside temperature. It is best to check tire
pressure outdoors before driving the
vehicle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to
increase. Be careful not to mistakenly
release air from a warm tire to reduce its
pressure.
