■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. 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.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( P.281)
■Replacing 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
■Repairing or replacing tires, wheels, tire pressure warning
valves, transmitters and tire valve caps
●When 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.
●Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire
pressure warning valves, corrode the valve, and cause sticking and air leaks.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damage to the tire pres-sure warning valves and trans-mitters
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 as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when
replacing the tire. ( P.279)

■The tire pressure warning sys-
tem must be init ialized in the
following circumstances:
 When rotating front and rear tires
which have different tire inflation
pressures.
 When changing the tire size.
 When the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
 When changing between two
registered wheel sets.
When the tire pressure warning
system is initialized, the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system
1 Park the vehicle in a safe place
and turn the engine switch off,
wait for approximately 15 min-
utes or more and perform the
procedure.
2 Adjust the tire inflation pressure
to the specified cold tire inflation
pressure level. ( P.355)

ing for 1 hour or more, park the vehicle in a safe place for more than 15 min-utes and please drive a vehicle once
again with the engine switch ON. ( P.283)
■Initialization procedure
●Make 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.
●If you have accidentally turned the engine switch off during initialization, it is not necessary to press the reset
switch again as initialization will restart automatically when the engine switch is turned to ON the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the tires are cold, and conduct initialization
again.
●While 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.
■If the tire pressure warning system
is not initialized properly
●In the following situations, initialization
may take longer than usual to be com- pleted or may not be possible. (Usu-ally, the vehicle will need to be driven
for approximately 10 to 30 minutes to complete initialization.) If initialization is not complete after driving approxi-
mately 30 minutes, continue driving for a while.• If the vehicle is driven on an unpaved
road, it may take longer to complete initialization.• If the vehicle is backed up while per-
forming initialization, data collected during initialization will be cleared and it will take longer than normal to com-
plete.
• 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.
If initialization is not complete after driv-
ing for approximately 1 hour, park the
vehicle in a safe place for more than 15
minutes and then drive the vehicle
again.
●In 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 and then illuminates.
●If initialization cannot be completed after performing the above procedure,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
