Battery exterior

Make sure that the battery terminals are not corroded and that there are no loose connections, cracks, or loose clamps.

Terminals

Hold-down clamp

Before recharging

When recharging, the battery produces hydrogen gas which is flammable and explosive. Therefore, observe the following before recharging:

If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.

Make sure the power switch on the charger is off when connecting and dis- connecting the charger cables to the battery.

After recharging/reconnecting the battery (vehicles with a smart key sys- tem)

Unlocking the doors using the smart key system may not be possible imme- diately after reconnecting the battery. If this happens, use the wireless remote control or the mechanical key to lock/unlock the doors.

Start the engine with the engine switch in ACCESSORY mode. The engine may not start with the engine switch turned off. However, the engine will operate normally from the second attempt.

The engine switch mode is recorded by the vehicle. If the battery is recon- nected, the vehicle will return the engine switch mode to the status it was in before the battery was disconnected. Make sure to turn off the engine before disconnect the battery. Take extra care when connecting the battery if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact your Toyota dealer.

Treadwear indicator

The location of treadwear indicators is shown by a“TWI” or“Δ” mark, etc., molded into the sidewall of each tire.

Replace the tires if the treadwear indicators are showing on a tire.

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.

7-3. Do-it-yourself maintenance

441

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 ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized. Have tire pressure warning valves and transmitter ID codes registered by your Toyota dealer. (P. 443)

Initializing the tire pressure warning system

The tire pressure warning system must be initialized in the fol- lowing circumstances:

When changing the tire size.

When the tire inflation pressure is changed such as when chang- ing traveling speed or load weight.

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

442 7-3. Do-it-yourself maintenance

How to initialize the tire pressure warning system

Initialization cannot be performed while the vehicle is moving. Adjust the tire inflation pressure to the specified cold tire inflation pressure level. (P. 546)

Make sure to adjust the tire pressure to the specified cold tire infla- tion pressure level. The tire pressure warning system will operate based on this pressure level.

Turn the engine switch to the“ON” position (vehicles without a smart key system) or IGNITION ON mode (vehicles with a smart key system).

Open the glove box. Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly 3 times.

Vehicles without a smart key system: Wait for a few minutes with the engine switch in the“ON” position and then turn the engine switch to the“ACC” or“LOCK” position.

Vehicles with a smart key system: Wait for a few minutes with the engine switch in IGNITION ON mode and then turn the engine switch off.

Registering ID codes

7-3. Do-it-yourself maintenance

443

When to replace your vehicle’s tires

Tires should be replaced if:

The treadwear indicators are showing on a tire.

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 (vehicles with a tire pressure warning system)

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 (vehicles with a tire pressure warning system)

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 (17-inch tires)

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

444 7-3. Do-it-yourself maintenance

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. (P. 551)

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. 263)

Initializing the tire pressure warning system (vehicles with a tire pressure warning system)

Initialize the system with the tire inflation pressure adjusted to the speci- fied level.

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

The effectiveness of the tires as snow tires is lost.

7-3. Do-it-yourself maintenance

445

If you press the tire pressure warning reset switch accidentally (vehi- cles with a tire pressure warning system)

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

When initialization of the tire pressure warning system has failed (vehicles with a tire pressure warning system)

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

When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times.

After driving for a certain period of time since the initialization has been completed, the warning light comes on after blinking for 1 minute.

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 economy

Reduced driving comfort and poor handling

Reduced tire life due to wear

Reduced safety

Damage to the drive train

If a tire needs frequent inflating, have it checked by your Toyota dealer.

450 7-3. Do-it-yourself maintenance

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.

It is difficult to judge if a tire is properly inflated based only on its appear- ance.

It is normal for the tire inflation pressure to be higher after driving as heat is generated in the tire. Do not reduce tire inflation pressure after driving.

Never exceed the vehicle capacity weight.

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

7-3. Do-it-yourself maintenance

451

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

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 (vehicles with a tire pressure warning sys- tem)

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. 441)
