◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a unique ID
code. When replacing a tire pressure wa rning valve and transmitter, it is nec-
essary 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:
●The treadwear indicators are showing on a tire.
●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 prop erly 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.
■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 proper ly. After driving for about 10 minutes, the tire pressure warning light blinks for 1 minu te and stays on to indicate a system malfunc-
tion.
■Tire life
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 re place routine tire inflation pressure checks.
Make sure to check tire inflation pressure as part of your routine of daily vehicle checks.
■Initializing the tire pressure warning system
Initialize the system with the tire inflatio n pressure adjusted to the specified level.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, ad just the tire inflation pressure to the specified level and ini- tialize the tire pressure warning system again.

■Warning performance of the tire pressure warning system
The warning of the tire pressure warning syst em will change in accordance with the con- ditions under which it was initialized. For this reason, the system may give a warning even
if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.
■When initialization of the tire pressure warning system has failed
Initialization may take longer to complete if the vehicle is driven on an unpaved road. When performing initialization, drive on a paved road if possible. Depending on the driv- ing environment and cond ition of the tires, initialization will be completed in approxi-
mately 10 to 30 minutes. If initialization is not complete after driving approximately 10 to 30 minutes, continue driving for a while.
If the inflation pressure of each tire is not displayed after driving for approximately 1 hour,
perform the following procedure.
●Park the vehicle in a safe place for approxim ately 20 minutes. Then drive straight (with occasional left and right turns) at appr oximately 40 km/h (25 mph) or more for
approximately 10 to 30 minutes.
However, in the following situations, the tire inflation pressure will not be recorded and the system will not operate proper ly. Perform initialization again.
●When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times.
●After performing initialization, the tire pre ssure warning light blinks for 1 minute then
stays on while driving.
If the inflation pressure of each tire is still not displayed, have the vehicle inspected by any authorized Lexus dealer or repairer, or anot her duly qualified and equipped professional.
