transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system.
 When “Adjust Pressure” is dis-
played (Normal Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance of the tire
due to natural air leakage as well as the
pressure lowering due to changes in
the pressure according to the outside
temperature.
 When “Immediately Check tyre
when Safe” is displayed (Emer-
gency Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is a known level of low tire pres-
sure with the appearance of the tire due
to pressure suddenly lowering.
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
 The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-infor-
mation display.

■When rotating the tires
It is necessary to register the posi-
tion of each wheel after performing
a tire rotation.
Wheel position registration can be
performed by oneself. Wheel posi-
tion registration is performed by
driving forward with moderate left
and right turns. However, depend-
ing on the driving conditions and
driving environment, registration
may take some time to complete.
■Registration of the tire posi-
tion
1 Park the vehicle in a safe place
and stop the EV system for 15
minutes or more.
2 Start the EV system (P.243)
Registration cannot be performed while the vehicle is moving.

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 and the tire pressure warning valves could be bound.
●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 or other qualified ser- vice shop as soon as possible. After use of liquid sealant, make sure to
replace the tire pressure warning valve and transmitter when repairing or replacing the tire.

 When the tire inflation pressure
is changed such as when the tire
size is changed.
If the tire inflation pressure has
been adjusted to the specified
level, perform the tire inflation set-
ting procedure by selecting speci-
fied inflation pressure on the multi-
information display.
When the tire inflation pressure is
to be other than specified, such as
when tires other than the specified
size are used, etc., set the tire infla-
tion pressure using the current
pressure. Make sure to adjust the
tire inflation pressure of each tire to
the appropriate level before per-
forming tire pressure setting. The
tire pressure warning system oper-
ates based on this tire inflation
pressure.
■Setting by selecting a speci-
fied tire inflation pressure
1 Start the EV system (P.243)
The tire inflation pressure cannot be set while the vehicle is moving.

■Warning performance of the tire pressure warning system (Setting
using the current tire inflation pres- sure)
●When performing the tire pressure setting using the current tire inflation pressure, the warning timing of the tire
pressure warning system will vary according to the conditions under which tire pressure setting was per-
formed. Therefore, a warning may be output even if the tire inflation pres-
sure drops slightly or if the tire inflation pressure increases above that when the tire inflation pressure was set.
●Make sure to perform the tire pressure setting procedure after adjusting the
tire inflation pressure. Also, make sure the tires are cold before performing the tire pressure setting procedure or
adjusting the tire inflation pressure.

■Tire inflation pressure setting pro-
cedure (Setting using the current tire inflation pressure)
●If the power switch is turned off while setting the tire inflation pressure, the next time the power switch is turned to
ON, the setting procedure will resume and it will not be necessary to restart the procedure.
●If the tire inflation pressure setting procedure is started unnecessarily,
adjust the tire inflation pressure to the specified level with the tires cold and then perform setting by selecting a
specified tire inflation pressure, or per- form the tire inflation pressure setting procedure with the current tire inflation
pressure.
■If the tire inflation pressure cannot be set properly
●Normally, the tire inflation pressure setting procedure can be completed in 2 or 3 minutes.
●If the tire pressure warning light does not blink 3 times when starting the tire
inflation pressure setting procedure, the procedure may not have started. Perform the procedure again from the
beginning.
●If tire inflation pressure setting proce-
dure cannot be completed after per- forming the above procedure, contact by any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer.
■When the registering ID codes
The tire pressure warning valve
and transmitter is equipped with a
unique ID code.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer.
■How to registration ID code
1 Park the vehicle in a safe place,
wait for approximately 15 min-
utes.
2 Start the EV system. (P.243)
The ID code registration procedure
cannot be performed while the vehicle is moving.
3 Press or of the meter
control switches and select .
4 Press or of the meter
control switches and select
“Vehicle Settings”, and then

WARNING
■When setting using the current
tire inflation pressure
Make sure to adjust the tire inflation pressure of each tire to the appropri-
ate level before performing tire pres- sure setting. Otherwise, the tire pressure warning light may not illumi-
nate even if the tire inflation pressure drops or may illuminate even though the tire inflation pressure is normal.
