Selecting ID codes

When replacing tires, make sure to select the ID code set that matches

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

setting, the system will not work properly. After about 1 hour, the tire

pressure warning light blinks (comes on after blinking for 1 minute) to

indicate a system malfunction.

Switching ID codes

Push the tire pressure warning

select switch to select MAIN or

2nd ID codes.

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.

■

Tire life

Any tire over 6 years old must be checked by a qualified technician even if they

have seldom or never been used or damage is not obvious.

■

If the tread wears down below 0.16 in. (4 mm) on snow tires

The effectiveness of snow tires is lost.
