Registering ID codes

The tire pressure warning valve and transmitter is equipped with

a unique ID code. When replacing a tire pressure warning valve

and transmitter, it is necessary to register the ID code. Have the

ID code registered by any authorized Lexus dealer or repairer, or

another duly qualified and equipped professional.

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

fabric, and bulges indicating internal damage

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

location of a cut or other damage

If you are not sure, consult with any authorized Lexus dealer or repairer, or

another duly qualified and equipped professional.

If the ID code of the tire pressure warning valve and transmitter is not regis-

tered, the tire pressure warning system will not work properly. After driving

for about 10 minutes, the tire pressure warning light blinks for 1 minute and

stays on to indicate a system malfunction.

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

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

Routine tire inflation pressure checks

The tire pressure warning system does not replace routine tire inflation pres-

sure checks. Make sure to check tire inflation pressure as part of your routine

of daily vehicle checks.

When rotating the tires

Make sure that the engine switch is off. If the tires are rotated while the

engine switch is in IGNITION ON mode, the tire position information will

not be updated.

If this accidentally occurs, either turn the engine switch to off and then to

IGNITION ON mode, or initialize the system after checking that the tire

pressure is properly adjusted.
