taken for the warning to start or go off
could be extended.
OWhen tire inflation pressure declines
rapidly for example when a tire has burst, the warning may not function.
QWarning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance with the conditions under which it was initial-
ized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if
the pressure is higher than the pressure that was adjusted to when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
( P.470)
QWhen replacing the tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis- tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunc-
tion.

ing valves and transmitters
NOTICE
QRepairing or replacing tires, wheels, tire pressure warning
valves, transmitters and tire valve caps
OWhen removing or fitting the
wheels, tires or the tire pressure warning valves and transmitters, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as the tire pressure warning valves
and transmitters may be damaged if not handled correctly.
OMake sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire
pressure warning valves and the tire pressure warning valves could be bound.
OWhen replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
QTo avoid damage to the tire pres-sure warning valves and trans-mitters (vehicles without spare
tire)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is used, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer or other qualified ser-vice shop as soon as possible. Make
sure to replace the tire pressure warn- ing valve and transmitter when repair-ing or replacing the tire. ( P.465,

more for approximately 10 to 30
minutes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information dis-
play.
Even if the vehicle is not driven at
approximately 40 km/h (25 mph) or
more, initialization can be completed by
driving for a long time. However, if ini-
tialization does not complete after driv-
ing for 1 hour or more, park the vehicle
in a safe place for approximately 20
minutes and then drive the vehicle
again.
QWhen initializing
OInitialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
OMake sure to carry out initialization
after adjusting the tire inflation pres-
sure. Also, make sure the tires are
cold before carrying out initialization
or tire inflation pressure adjustment.
OThe tire pressure warning system can
be initialized by yourself, but depend-
ing on the driving conditions and driv-
ing environment, initialization may
take some time to complete.
QThe initialization operation
OIf you have accidentally turned the
power switch to OFF during initializa-
tion, it is not necessary to restart the
initialization again as initialization will
restart automatically when the power
switch has been turned to ON for the
next time.
OIf you accidentally perform initializa-
tion when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization
again.
OWhile the position of each tire is being
determined and the inflation pres-
sures are not being displayed on the
multi-information display, if the infla-tion pressure of a tire drops, the tire
pressure warning light will come on.
QIf the tire pressure warning system
is not initialized properly
OIn the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Nor-
mally, initialization completes within
approximately 30 minutes.
• Vehicle is not driven at approximately
40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit-
ters of your vehicle over those of other
vehicles.
• If the vehicle is driven in heavy traffic
or another situation where other vehi-
cles are driven close by, it may take
time for the system to recognize the
tire pressure warning valve and trans-
mitters of your vehicle over those of
other vehicles.
OIf initialization does not complete after
driving for 1 hour or more, park the
vehicle in a safe place for approxi-
mately 20 minutes and then drive the
vehicle again.
OIf the vehicle is reversed during initial-
ization, the data up to that point is
reset, so perform the initialization pro-
cedure again from the beginning.
OIn the following situations, initialization
will not be started or was not com-
pleted properly and the system will not
operate properly. Perform the initial-
ization procedure again.
• If, when attempting to start initializa-
tion, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven
for about 20 minutes after performing
initialization, the tire pressure warning
light blinks for approximately 1 minute

ing system. (P.468)
QWhen registering ID codes
OID code registration is performed
while driving at a vehicle speed of
approximately 40 km/h (25 mph) or
more.
OBefore performing ID code registra-
tion, make sure that no wheels with
tire pressure warning valve and trans-
mitters installed are near the vehicle.
OMake sure to initialize the tire pres-
sure warning system after registering
the ID codes. If the system is initial-
ized before registering the ID codes,
the initialized values will be invalid.
OID codes can be registered by your-
self, but depending on the driving con-
ditions and driving environment,
registration may take some time to
complete.
OAs the tires will be warm when regis-
tration is completed, make sure to
allow the tires to cool before perform-
ing initialization.
QCanceling ID code registration
OTo cancel ID code registration after it
has been started, select “Identifying
Each Wheel & Position” on the multi-
information display and press and
hold again.
OIf ID code registration has been can-
celed, the tire pressure warning light
will blink for approximately 1 minute

QEffects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres-
sure may result in the following:
OReduced fuel economy
OReduced driving comfort and poor
handling
OReduced tire life due to wear
OReduced safety
ODamage to the drive train
If a tire needs frequent inflating, have it
checked by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer.
QInstructions for checking tire infla-
tion pressure
When checking tire inflation pressure,
observe the following:
OCheck only when the tires are cold.
If your vehicle has been parked for at
least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you
will get an accurate cold tire inflation
pressure reading.
OAlways use a tire pressure gauge.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
OIt is normal for the tire inflation pres-
sure to be higher after driving as heat
is generated in the tire. Do not reduce
tire inflation pressure after driving.
OPassengers and luggage weight
Tire inflation pressure
Make sure to maintain the
proper tire inflation pressure.
Tire inflation pressure should
be checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. (P.564)
