Tires

Replace tires when the treadwear indicators show.
■ Checking tires
■ The tire pressure warning system
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. (P. 315)
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters 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 tire pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Lexus dealer.
