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 pres-
sure 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. 802, 808)
The tire pressure detected by the tire pressure
●
warning system can be displayed on the multi-
information display. (P. 96)
◆
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 the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes registered by your Lexus
dealer. (P. 762)
◆
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
●
traveling speed.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
