the new tire set. If the tire pressure select switch is set to the 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.

When to replace your vehicle±s tires

Tires should be replaced if:

●

You have tire damage such as cuts, splits, cracks deep enough to expose the fab-

ric or bulges indicating internal damage

●

A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-

tion of a cut or other damage

If you are not sure, consult with your Lexus dealer.

the tire pressure warning system will not work properly. After about 20 minutes, the

malfunction.
