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.

■

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 the

wrong tire setting, the tire pressure warning system will not operate

properly. After driving for about 20 minutes, the tire pressure warning

light comes on after blinking for 1 minute to indicate a system malfunc-

tion.
