Maintenance and care
Installing tire pressure warning valves and transmittersWhen replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning va lves and transmitters are installed,
sensor ID codes must be registered in the tire pressure warning ECU.
Registering and selecting ID codes
■ Registering ID codes
2 sets of tire pressure warning va lve and transmitter ID codes can be
registered. Once a second set of ti res (winter tires etc.) is registered at
“2nd”, you can switch between tire set settings simply by pressing the
tire pressure warning select switch.
There are 2 settings:
“MAIN” position: The ID code of the tire pressure warning valve and
transmitter on the tires originally installed on the vehicle is registered.
“2nd” position: The code is not registered. When you replace a new set
of tires, purchase tire pressure warning valves and transmitters from
your Lexus dealer and have the new ID code registered by your Lexus
dealer.
