◆ Installing tire pressure warning valve and transmitters

When replacing the tires or wheels, the tire pressure warning valve and transmitters must be installed to the wheels which will be installed to the vehicle.

When new tire pressure warning valve and transmitters are installed, new ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized.

◆ Initializing the tire pressure warning system

■ The tire pressure warning system must be initialized in the following circumstances:

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure.

■ How to initialize the tire pressure warning system

1. Park the vehicle in a safe place and stop the engine for 20 minutes or more.

The initialization procedure cannot be started while the vehicle is moving.

2. Adjust the tire inflation pressure to the specified cold tire inflation pressure level. Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level.

3. Start the engine.

4. Select (4.2-inch display) or (7-inch display) on the multi-information display using the meter control switches on the steering wheel.

5. 4.2-inch display: Select "Vehicle Settings" and then press .

7-inch display: Select and then press and hold .

6. Select "TPWS" and then press .

7. Select "Set Pressure" then press and hold until the tire pressure warning light blinks 3 times.

Then a message will be displayed on the multi-information display.

Vehicles with a tire inflation pressure display function: "- -" will be displayed on the multi-information display for the inflation pressure of each tire while initialization is being performed.

8. Vehicles with a tire inflation pressure display function: Drive at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes.

When initialization is complete, the inflation pressure of each tire will be displayed on the multi-information display.

Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, initialization can be completed by driving for a long time.

However, if initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.

◆ Registering ID codes

Vehicles without a tire inflation pressure display function

Every tire pressure warning valve and transmitter has a unique ID code. In addition to the set of tire pressure warning system sensor ID codes initially registered to the vehicle, a second set of ID codes can be registered.

A second set of tire pressure warning system sensor ID codes can be registered at your Toyota dealer. When 2 sets of ID codes have been registered, either ID code set can be selected.

Vehicles with a tire inflation pressure display function

Every tire pressure warning valve and transmitter has a unique ID code. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID codes.

The ID codes can be registered on (4.2-inch display) or (7- inch display) of the multi-information display.

■ Changing the available set of ID codes (vehicles without a tire inflation pressure display function)

When 2 sets of ID codes are registered, the corresponding ID code set for the installed wheels can be selected on (4.2-inch display) or (7-inch display) of the multi-information display. It is not necessary to reregister the ID codes each time the wheels are changed.

For information regarding changing the registered ID codes for an ID code set, contact your Toyota dealer.

■ How to register the ID codes (vehicles with a tire inflation pressure display function)

1. Park the vehicle in a safe place, wait for approximately 20 minutes, and then start the engine.

2. Select (4.2-inch display) or (7-inch display) on the multi-information display using the meter control switches on the steering wheel.

3. 4.2-inch display: Select "Vehicle Settings" and then press .

7-inch display: Select and then press and hold .

4. Select "TPWS" and then press .

5. Select "Change Wheel" then press and hold until the tire pressure warning light blinks slowly 3 times.

Then a message will be displayed on the multi-information display.

When registration is being performed, the tire pressure warning light will blink for approximately 1 minute then illuminate and "- -" will be displayed for the inflation pressure of each tire on the multi-information display.

6. Drive at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes.

Registration is complete when the tire pressure warning light turns off and the inflation pressure of each tire is displayed on the multi-information display.

Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, registration can be completed by driving for a long time.

However, if registration does not complete after driving for 1 hour or more, perform the procedure again from the beginning.

7. Initialize the tire pressure warning system.

■When to replace your vehicle's tires

Tires should be replaced if:

If you are not sure, consult with your Toyota dealer.

■Replacing tires and wheels

If the ID codes of the tire pressure warning valve and transmitters are not registered, the tire pressure warning system will not work properly. In this case, after driving for about 20 minutes, the tire pressure warning light will blink for approximately 1 minute and then illuminate to indicate a system malfunction.

■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 replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks.

■Low profile tires (vehicles with 18 or 19-inch wheels)

Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when compared to standard tires. Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed appropriate for road and weather conditions.

■Maximum load of tire

Check that the maximum load of the replacement 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

■If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

■Situations in which the tire pressure warning system may not operate properly

■Initialization procedure

■Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accordance with the conditions 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.

■If the tire pressure warning system is not initialized properly

Vehicles without a tire inflation pressure display function

Initialization can be completed in a few minutes. However, in the following cases, the settings have not been recorded and the system will not operate properly. If repeated attempts to record tire inflation pressure settings are unsuccessful, have the vehicle inspected by your Toyota dealer.

WARNING

■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 an accident resulting in death or serious injury.

■When initializing the tire pressure warning system

Do not initialize the tire pressure warning system without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.

NOTICE

■Repairing or replacing tires, wheels, tire pressure warning valve and transmitters and tire valve caps

■To avoid damage to the tire pressure warning valve 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 Toyota 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 cushioning 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.

■Low profile tires (vehicles with 18 or 19-inch wheels)

Low profile tires may cause greater damage than usual to the tire wheel when sustaining impact from the road surface. Therefore, pay attention to the following:

■If tire inflation pressure of each tire becomes low while driving

Do not continue driving, or your tires and/or wheels may be ruined.
