Replace or rotate tires in accordance with maintenance schedules
and treadwear.
Checking tires Check if the treadwear indicators are showing on the tires. Also check the tires for uneven wear, such as excessive wear on one side of the tread. Check the spare tire condition and pressure if not rotated.
The location of treadwear indicators is shown by a "TWI" or "" mark, etc., molded into the sidewall of each tire. Replace the tires if the treadwear indicators are showing on a tire. Tire rotation Rotate the tires in the order shown. To equalize tire wear and extend tire life, Toyota recommends that tire rotation is carried out at the same interval as tire inspection. Do not fail to initialize the tire pressure warning system after tire rotation. Tire pressure warning system Your vehicle is equipped with a tire pressure warning system that uses tire pressure warning valve and transmitters to detect low tire inflation pressure before serious problems arise.
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 turn the engine switch off. 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 on the multi-information display using the meter control switches on the steering wheel. 5. 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. "---" will be displayed on the multi-information display for the inflation pressure of each tire while initialization is being performed. 8. Drive straight (with occasional left and right turns) at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes. Initialization is complete when the position of each tire is determined and the inflation pressure of each tire is displayed on the multi-information display. Initialization may take longer than approximately 1 hour in certain situations, such as when the vehicle is stopped for a long time at traffic lights, etc. Registering ID codes 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 of the multi-information display. ■ How to register the ID codes 1. Select on the multi-information display using the meter control switches on the steering wheel. 2. Select and then press and hold . 3. Select "TPWS" and then press . 4. 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. 5. Drive straight (with occasional left and right turns) 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. Registration may take longer than approximately 1 hour in certain situations, such as when the vehicle is stopped for a long time at traffic lights, etc. After registering the ID codes, make sure to 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
■When registering ID codes
■Canceling ID code registration
■If ID codes are not registered properly
