Setting the tire pressure warning system
To activate the tire pressure warning system, it is necessary to register the
ID code of the sender on the selector switch. Once registered, change
the setting position each time you replace the tires and wheels. Re-regis-
tration is no required.
■ Registering the ID code
ID codes should be registered by Lexus dealer. 2 sets of ID codes can
be registered. The code of the tires originally installed on the vehicle is
registered on the switch at "MAIN". Have a new tires set with new tire
pressure sensors registered at "2nd" by Lexus dealer.
