2008 SUBARU LEGACY TPMS reset

3-34Instruments and controls
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.
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
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should go
off a few minutes later. Therefore, be
sure to install the specified size for the front and rear tires.
& ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ”
position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, the ABS system may not
work properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. . The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. The warning light comes on when
the ignition switch is turned tothe “ON ”position, but it does not
go out even when the vehicle
speed exceeds approximately 8
mph (12 km/h).
. The warning light comes on dur-
ing driving. If any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
The ABS warning light comes on together
with the brake system warning light if the
EBD system becomes faulty. For further
details of the EBD system fault warning,
refer to “Brake system warning light ”.
NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. . The warning light comes on right
after the engine is started but goes out
immediately, remaining off.. The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).. The warning light comes on during
driving, but it goes out immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.

9-2In case of emergency
If you park your vehicle in an emergency
The 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 switchposition.
Turn on the hazard warning by pushing
the hazard warning flasher switch. Turn it
off by pushing the switch again. NOTE
When 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
illuminate steadily after blinking
for approximately one minute.
This indicates the tire pressure
monitoring system (TPMS) is un-
able to monitor all four road
wheels. Contact your SUBARU
dealer as soon as possible for
tire and sensor replacement 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)
Vehicle with SI-DRIVE
Vehicle without SI-DRIVE
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 thedriver
’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 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.
Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors. In case of emergency

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 snowtires), 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, 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 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 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.

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 illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all

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 inspection
Check 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 vehicleinspected.
& Tire pressures and wear
Maintaining 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 thevehicle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to
