The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after several minutes.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light.
The compact spare tire is not equipped
with the tire pressure warning valve and
transmitter. If a tire goes flat, the warning
light will not turn off even though the flat
tire is replaced with the spare tire. Re-
place the spare tire with the repaired tire
and adjust the proper tire inflation pressur-
e. The tire pressure warning light will turn
off after several minutes.CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.

If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
ECU.
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non−genuine Toyota wheels are used.
If tire chains are used.
If the tire pressure warning light continues
to come on after blinking for 1 minute
when the ignition key is turned to the
“ON” position, have the system checked
by your Toyota dealer.
Even if you use genuine wheels, the tire
pressure warning system may not work
properly with some types of tires. Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light.

This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.
NOTICE:
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable protec-
tion against harmful interference in a
residential installation. This equipment
generates, uses and can radiate radio
frequency energy and, if not installed
and used in accordance with the instruc-
tions, may cause harmful interference to
radio communications. However, there is
no guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful interfer-
ence to radio or television reception,
which can be determined by turning the
equipment off and on, the user is en-
couraged to try to correct the interfer-
ence by one or more of the following
measures:
−
Reorient or relocate the receiving an-
tenna.
− Increase the separation between the
equipment and receiver.

−Connect the equipment into an outlet
on a circuit different from that to which
the receiver is connected.
− Consult the dealer or an experienced
radio/TV technician for help.
FCC WARNING:
Changes or modifications not ex-
pressly approved by the party respon-
sible for compliance could void the
user’s authority to operate the equip-
ment.
For vehicles sold in Canada
Operation is subject to the following two
conditions: (1) this device may not
cause interference, and (2) this device
must accept any interference, including
interference that may cause undesired
operation of the device.
REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered in the tire pressure warning
ECU. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
If the ID code is not registered, the sys-
tem will not work properly. After about 20
min −drive, the tire pressure warning light
comes on after blinking for 1 minute to
indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.
TIRE PRESSURE WARNING RESET
SWITCH
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.

To initialize the system, perform the fol-
lowing:1. Park the vehicle in a safe place and turn the ignition key to the “ACC” or
“LOCK” position.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
517 in Section 8.)
3. Turn the ignition key to the “ON” posi- tion.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for several minutes with the igni- tion key “ON”, and then turn the igni-
tion key to the “ACC” or “LOCK” posi-
tion.
If you push the tire pressure reset switch
while vehicle is moving, initialization is not
performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.
If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Toyota dealer.
If turned ignition key to the “ACC” or
“LOCK” position before the initialization is
finished, the tire pressure warning light
may blink 3 times the next time the igni-
tion key is turned to the “ON” position.
CAUTION
Do not push the reset switch without
adjusting the tire inflation pressure to
the specified level. Otherwise, the tire
pressure warning light may not come
on even if the tire inflation pressure
is low, or it may come on when the
tire inflation pressure is actually nor-
mal.
