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 your Toyota dealer.
■
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 your Toyota dealer.
■
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure warning system will not work properly. After
driving for about 20 minutes, the tire pressure warning light blinks for
1 minute and stays on to indicate a system malfunction.
