The tire pressure warning system

Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise. (P. 747)

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 tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and the tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. (P. 687)

Initializing the tire pressure warning system

■ The tire pressure warning system must be initialized in the following
circumstances:
● When rotating the tires
● When the tire inflation pressure is changed such as when changing
travelling speed or load weight
● When changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
