■When rotating the tires
Make sure that the power switch is OFF.
If the tires are rotated while the power
switch is in ON, the tire position informa-
tion will not be updated.
If this accidentally occurs, either turn the
power switch to OFF and then to ON, or
initialize the system after checking that
the tire pressure is properly adjusted.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
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)
The tire pressure warning light comes
on and a buzzer sounds when the tire inflation pressure becomes low due to
natural air leakage or outside tempera-
ture. (Ways of coping: P.575, 624)
When “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low sud-
denly due to a blowout. (Ways of cop-
ing: P.575, 582, 593)
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-informa-
tion display.
The unit can be changed.
■How to change the unit
1Park the vehicle in a safe place
and turn the power switch off.
Changing the unit cannot be performed
while the vehicle is moving.
2Turn the power switch to ON.

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.
■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
When rotating the tires.
When changing the tire.
After registering the ID codes.
( P.525)
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 stop the hybrid system for
20 minutes or more.
Initialization 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 (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.511,

left and right turns) at approxi-
mately 40 km/h (25mph) or
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.
■When initializing
●Initialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
●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.
●The 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.
■The initialization operation
●If you have accidentally turned the

●If 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.
●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. 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.
●If 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.
●If 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.
●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, con-
tact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
Every tire pressure warning valve
and transmitter has a unique ID
code. When replacing a tire pres-
sure warning valve and transmitter,
it is necessary to register the ID
code.
When registering the ID codes, per-
form the following procedure.
1 Park the vehicle in a safe place,
wait for approximately 20 min-
utes, and then start the hybrid
system.
