Registering and selecting ID codes
n Registering ID codes
2 sets of tire pressure warning valve and transmitter ID codes can be
registered. Once a second set of tires 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 ID 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.
n Selecting ID codes
When replacing tires, make sure to select the ID code set that matches
the new tire set. If the tire pressure warning select switch is set to
wrong tire setting, the tire pressure warning system will not operate
properly. After about 20 minutes, the tire pressure warning light
comes on after blinking for 1 minute to indicate a system malfunction.
