Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure 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 warning light. (→P. 574)
◆ 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 your Lexus dealer. (→P. 527)
◆ Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following circum-
stances:
● When adjusting the tire inflation pressure
● When the tire inflation pressure is changed such as when changing travel-
ing speed.
● When rotating the tires
● When changing the tire.
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
pressure warning system can be dis-
played on the multi-information display.
