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 of tire pressure
warning valve and transmitter. 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 or 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 regis-
tered, the tire pressure warning system will not work properly. After driving
for about 20 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
