Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed. When new tire pressure warning valves and transmitters are installed, new tire pressure warning valve and transmitter ID codes must be registered in the tire pressure warning computer and tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer. (→P. 456)

Initializing the tire pressure warning system

n The tire pressure warning system must be initialized when the

tire size is changed

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the pressure benchmark. n How to initialize the tire pressure warning system STEP 1

Park the vehicle in a safe place and turn the engine switch to the “ACC” or “LOCK” position. While the vehicle is moving, initialization is not performed. Adjust the tire inflation pressure to the specified cold tire infla- tion pressure level. (→P. 548) 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. Turn the engine switch to the “ON” position.

n When to replace your vehicle's tires

Tires should be replaced if: l You have tire damage such as cuts, splits, cracks deep enough to

expose the fabric or bulges indicating internal damage

l 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 Toyota dealer.

n 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 indicate a system malfunction.

n 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.

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

The effectiveness of snow tires is lost.

n Maximum load of tire

Check that the maximum load of the replaced 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. As for the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight Ratings (GAWR), see the Certification Label. (→P. 543, 553).

n 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 performance 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 adequate for driving in most winter conditions, as well as for use year round. All season 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, con- struction and load capacity 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. (→P. 226) n Initializing the tire pressure warning system

Initialize the tire pressure warning system with the tire inflation pressure adjusted to the specified level.

n If you push the tire pressure warning reset switch accidentally

If initialization is performed, adjust the tire inflation pressure to the speci- fied level and initialize the tire pressure warning system again.

n When the initialization of the tire pressure warning system has

failed Initialization can be completed in several minutes. However, in the fol- lowing 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. l When operating the tire pressure warning reset switch, the tire pres-

sure warning light does not flash 3 times.

l After carrying out the initialization procedure, the tire pressure warn- ing light blinks for 1 minute then stays on after driving for about 20
minutes.

n 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.

NOTICE

n Repairing or replacing tires, wheels and tire pressure warning

valves and transmitters When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Toyota dealer as the tire pressure warning valve and transmitter may be damaged if not handled correctly. n To avoid damaging the tire pressure warning valves and transmit-

ters Do not use liquid sealants on flat tires.

n Do not use puncture sealant sprays to repair flats

Puncture sealant sprays may damage tire pressure warning valves and transmitters.

n Driving on rough roads

Take particular care when driving on roads with loose surfaces or pot- holes. 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.

n If tire inflation pressures become low while driving

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

n Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following: l Reduced fuel efficiency l Reduced driving comfort and tire life l Reduced safety l Damage to the drive train If a tire needs frequent refilling, have it checked by your Toyota dealer.

n Instructions for checking tire inflation pressure

When checking tire inflation pressure, observe the following: l Check only when the tires are cold.

If your vehicle has been parked for at least 3 hours and has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.

l Always use a tire pressure gauge.

The appearance of the tire can be misleading. In addition, tire infla- tion pressures that are even just a few pounds off can degrade ride and handling.

l Do not bleed or reduce tire inflation pressure after driving. It is normal

for the tire inflation pressure to be higher after driving.

l Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is balanced.

If a wheel is bent, cracked or heavily corroded, it should be replaced. Otherwise, the tire may separate from the wheel or cause loss of handling control. n Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset. Replacement wheels are available at your Toyota dealer. Toyota does not recommend using: l Wheels of different sizes or types l Used wheels l Bent wheels that have been straightened

n Aluminum wheel precautions

l Use only Toyota wheel nuts and wrenches designed for use

with your aluminum wheels.

l When rotating, repairing or changing your tires, check that the

wheel nuts are still tight after driving 1000 miles (1600 km).

l Be careful not to damage the aluminum wheels when using

tire chains.

l Use only Toyota genuine balance weights or equivalent and a

plastic or rubber hammer when balancing your wheels.

n When replacing wheels

The wheels of your Toyota are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advanced warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be installed. (→P. 455)
