Your vehicle is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low tire
inflation pressure before serious problems arise.
 If the tire pressure drops below a predetermined level, the driver
is warned by a screen display and a warning light. (P. 855,
859)
 Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves 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. Have tire pressure warning valve and transmitter ID
codes registered by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional. (P. 814)
 Initializing the tire pressure warning system
 The tire pressure warning system must be initialized in the fol-
lowing circumstances:
 When rotating the tires.
 When the tire inflation pressure is changed such as when
changing traveling speed.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the benchmark pressure.
Tire pressure warning system
 The tire pressure detected by the tire pres-
sure warning system can be displayed on
the multi-information display. (P. 128)
