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 ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer. (P. 365)

◆ 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 Toyota 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, and 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 Toyota dealer.

■Replacing tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not reg- istered, the tire pressure warning system will not work properly. After driv- ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on 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.

■Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 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. (P. 469)

■Tire types

●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 install- ing snow tires, be sure to replace all four tires.

●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 com- pared with summer tires in highway driving.

●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 restrictions. Snow tires should be installed on all wheels. (P. 268)

CAUTION

■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. ●Do not mix tires of different makes, models or tread patterns.

Also, do not mix tires of remarkably different treadwear.

●Do not use tire sizes other than those recommended by Toyota. ●Do not mix differently constructed tires (radial, bias-belted or bias-ply

tires).

●Do not mix summer, all season and snow tires. ●Do not use tires that have been used on another vehicle.

Do not use tires if you do not know how they were used previously.

NOTICE

■Repairing or replacing tires, wheels, tire pressure warning valves,

transmitters and tire valve caps ●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pres- sure warning valves and transmitters may be damaged if not handled correctly.

●When replacing tire valve caps, do not use tire valve caps other than

those specified. The cap may become stuck.

■To avoid damage to the tire pressure warning valves and transmit-

ters 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. (P. 365)

■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.

■If tire inflation pressure of each tire becomes low while driving Do not continue driving, or your tires and/or wheels may be ruined.

Inspection and adjustment procedure

Tire valve Tire pressure gauge

Remove the tire valve cap. Press the tip of the tire pressure gauge onto the tire valve. Read the pressure using the gauge gradations. If the tire inflation pressure is not at the recommended level, adjust the pressure. If you add too much air, press the center of the valve to deflate. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage. Put the tire valve cap back on.

■Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once a month. Do not forget to check the spare.

■Effects of incorrect tire inflation pressure

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

■Instructions for checking tire inflation pressure

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

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

●Always use a tire pressure gauge.

The appearance of the tire can be misleading. In addition, tire inflation pressure that is even just a few pounds off can affect ride quality and handling.

●Do not reduce tire inflation pressure after driving. It is normal for tire

inflation pressure to be higher after driving. ●Never exceed the vehicle capacity weight.

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

CAUTION

■Proper inflation is critical to save tire performance

Keep your tires properly inflated. Otherwise, the following conditions may occur and result in an accident causing death or serious injury: ●Excessive wear ●Uneven wear ●Poor handling ●Possibility of blowouts resulting from overheated tires ●Poor sealing of the tire bead ●Wheel deformation and/or tire separation ●A greater possibility of tire damage from road hazards

NOTICE

■When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on. Without the valve caps, dirt or moisture could get into the valve and cause air leakage, which could result in an accident. If the caps are lost, replace them as soon as possible.

Wheels

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

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 inset*. Replacement wheels are available at your Toyota dealer. *: Conventionally referred to as “offset”. Toyota does not recommend using the following: ● Wheels of different sizes or types ● Used wheels ● Bent wheels that have been straightened Aluminum wheel precautions ● Use only Toyota wheel nuts and wrenches designed for use with

your aluminum wheels.

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

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

● Be careful not to damage the aluminum wheels when using tire

chains.

● Use only Toyota genuine balance weights or equivalent and a plas-

tic or rubber hammer when balancing your wheels.

■When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning valves and trans- mitters must be installed. (P. 365)

CAUTION

■When replacing wheels

●Do not use wheels that are a different size from those recommended in

the Owner’s Manual, as this may result in a loss of handling control.

●Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing death or seri- ous injury.

■When installing the wheel nuts

●Be sure to install the wheel nuts with the inward. Installing the nuts with the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come off while driving, which could to an accident resulting in death or serious injury.

lead

Tapered portion

●Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off, causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts or wheel nuts.
