◆Installing tire pressure warning valves and transmitters
When replacing the tires or wheels, the tire pressure warning v alve
and transmitters must be install ed to the wheels which will be
installed to the vehicle.
When new tire pressure warning valve and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. ( P. 448)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
● When the tire inflation pressure is changed such as when the ti re
size is changed.
● When rotating the tires.
● Vehicles with a tire inflation pr essure display function: After per-
forming the transmitter ID code registration procedure. ( P. 4 4 8 )
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and stop the hybrid system for 20
minutes or more.
The initialization procedure cannot be started while the vehicle is
moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 550)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
Start the hybrid system. ( P. 2 0 6 )
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the ste er-
ing wheel. ( P. 109, 126).
4.2-inch display: Select “Vehi cle Settings” and then press .

inflation pressure of each tire
while initialization is being per-
formed.
Vehicles with a tire inflation pressure display function: Drive at
approximately 25 mph (40 km/h) 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 display.
Even if the vehicle is not driven at approximately 25 mph (40 k m/h)
or more, initialization can be completed by driving for a long time.
However, if initialization does not complete after driving for 1 hour or
more, park the vehicle in a safe place for approximately 20 min utes
and then drive the vehicle again.

◆Registering ID codes
Vehicles without a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. In addition to the set of tire pressure warning system se nsor
ID codes initially registered to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes ca n
be registered at your Toyota dealer. When 2 sets of ID codes ha ve
been registered, either ID code set can be selected.
Vehicles with a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmit ter,
it is necessary to reg ister the ID codes.
The ID codes can be registered on (4.2-inch display) or (7-
inch display) of the multi-information display.
■Changing the available set of ID codes (vehicles without a tire
inflation pressure display function)
When 2 sets of ID codes are reg istered, the corresponding ID code
set for the installed wheels can be selected on (4.2-inch disp lay)
or (7-inch display) of the multi-information display. It is no t nec-
essary to reregister the ID codes each time the wheels are
