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 comes on after blinking for 1 minute to indi- cate a system malfunction.
- 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.
- If the tread on snow tires wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of the tire as snow tires is lost.
- Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replace- ment tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire.
- Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction perfor- mance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires is recommended. When installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in snow and to be ade- quate for driving in most winter conditions, as well as for use year round. All sea- son tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving.
3 Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capac- ity as the originally installed tires. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restriction.
Snow tires should be installed on all wheels.
- 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.

NOTE:
Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interfer- ence that may cause undesired operation of the device.
CAUTION
- Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire bursts or if sudden air leakage occurs.
- When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drive train, as well as dangerous handling characteristics, which may lead to fatal or injury accidents.
• Do not mix tires of different makes, models, tread patterns or treadwear.
• Do not use tire sizes other than those recommended by Lexus.
• Do not mix radial, bias-belted, or bias-ply tires.
• Do not mix summer, all season and winter tires.
NOTICE
- Repairing or replacing tires, wheels, tire pressure warning valves and transmitters and tire valve caps
• When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Lexus dealer as the tire pressure warning valve and transmitter may be damaged if not handled correctly.
• When replacing tire valve caps, do not use tire valve caps other than those speci- fied. The cap may become stuck.
- To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Lexus dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire.
- Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion- ing ability of the tires. In addition driving on rough roads may cause damage to the tires themselves, as well as the vehicle’s wheels and body.
- If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
