Maintenance and care
●When replacing only the tire, the sensor already installed on the wheel
does not need to be replaced.
● Replacing both a wheel and its sensor.
When new tire pressure sensors are installed, new sensor ID codes must be
registered in the ECU and tire inflatio n pressure sensor must be initialized.
( P. 2 8 1 , 2 8 2 )
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
●When the standard tire pressure changes by replacing tires or
wheels
● When tires are rotated.
● When tire pressure sensors are replaced.
● When driving with the tires inflated to a higher than standard tire
pressure.
When the tire pressure warning sy stem is initialized, the current tire
pressure is set as the pressure benchmark.
■ How to initialize the tire pressure warning system
To initialize the system, use the satellite switch. ( P. 218)
Park the vehicle in safe place and turn off the engine.
Adjust the tire pressure to the specified pressure ( P. 383)
Start the engine.
Make sure to adjust the tire pressure to the specified level. The tire infla-
tion pressure warning system will operate based on this pressure level.

It may take several minutes to com-
plete the setting. Wait for several
minutes before turning the engine
switch OFF if necessary.
Recording tire pressure settings
Press the ON/OFF button for
more than 3 seconds. At this time,
the tire inflation pressure warning
indicator flashes 3 times and the
message showing that the initial
setting is complete is displayed on
the multi-information display.
Registering and selecting tire inflation pressure sensor ID codesThe tire inflation pressure sensor is equipped with a unique ID code.
To select tire inflation pressure sensor ID codes, use the satellite switch.
( P. 218)
■ Registering ID codes
Two separate sets of ID codes can be registered for each vehicle. This
allows 2 separate sets of settings to be conveniently recorded for all
season and winter tires.
MAIN: The MAIN ID code is used fo r the factory installed tire pres-
sure sensors.
2nd: The 2nd ID code is used for tire inflation pressure sensors associ-
ated with a secondary set of tires.
Make sure to have all tire inflation pressure warning system ID codes regis-
tered by your Lexus dealer. ID codes must be reset when tires or wheels are
replaced.
