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 for 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.
