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
Lexus 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 Lexus 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 flashes for 1 minute to indicate a system mal-
function.
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.
Routine tire inflation pressure checks
■
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
Tire rotation
■
It is not possible to rotate the tires, as each tire is designed only for its original posi-
tion on the vehicle.
