■Engine oil consumption

●The amount of engine oil consumed depends on the oil viscosity, the

quality of the oil and the way the vehicle is driven.

●More oil is consumed under driving conditions such as high speeds and

frequent acceleration and deceleration.

●A new engine consumes more oil. ●When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accu- rately.

●Oil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/

1000 km)

●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600

miles (1000 km), contact your Toyota dealer.

CAUTION

■Used engine oil

●Used engine oil contains potentially harmful contaminants which may cause skin disorders such as inflammation and skin cancer, so care should be taken to avoid prolonged and repeated contact. To remove used engine oil from your skin, wash thoroughly with soap and water.

●Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and filters in household trash, in sewers or onto the ground. Call your Toyota dealer, service station or auto parts store for information concerning recycling or disposal.

●Do not leave used engine oil within the reach of children.

Engine coolant

The coolant level is satisfactory if it is between the “F” and “L” lines on the reservoir when the engine is cold.

Reservoir cap “F” line “L” line If the level is on or below the “L” line, add coolant up to the “F” line. (→P. 627)

CTH43AS108

■Coolant selection

Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.

U.S.A.:

“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31°F [-35°C]) Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44°F [-42°C])

For more details about engine coolant, contact your Toyota dealer.

■If the coolant level drops within a short time of replenishing

Visually check the radiator, hoses, engine coolant reservoir caps, drain cock and water pump. If you cannot find a leak, have your Toyota dealer test the cap and check for leaks in the cooling system.

CAUTION

■When the engine is hot

Do not remove the engine coolant reservoir cap. The cooling system may be under pressure and may spray hot coolant if the cap is removed, causing serious injuries, such as burns.

NOTICE

■When adding coolant

Coolant is neither plain water nor straight antifreeze. The correct mixture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be sure to read the antifreeze or coolant label.

■If you spill coolant

Be sure to wash it off with water to prevent it from damaging parts or paint.

Radiator and condenser

Check the radiator and condenser and clear away any foreign objects. If either of the above parts is extremely dirty or you are not sure of their condition, have your vehicle inspected by your Toyota dealer.

4-3. Do-it-yourself maintenance

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 the tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer. (→P. 538)

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 of tire pressure warning valve and transmitter. Have the ID code registered by your Toyota dealer.

4-3. Do-it-yourself maintenance

■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 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.

■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.

■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. 648)

4-3. Do-it-yourself maintenance

■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 installing 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 compared 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. 288)

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

The effectiveness of the tires as snow tires is lost.

■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 transmitter 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 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 replac- ing the tire. (→P. 538)

■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 vehi- cle’s wheels and body.

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

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

■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 infla- tion 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.

4RUNNER_U

4-3. Do-it-yourself maintenance

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.

546

4RUNNER_U

4-3. Do-it-yourself maintenance 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.

● When balancing your wheels, use only Toyota genuine bal- ance weights or the equivalent. If clip-on balance weights are being used, use a plastic or rubber hammer to install the weight.

547

4RUNNER_U

4-3. Do-it-yourself maintenance

■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 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. 538)

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 tube- less tire. Doing so may result in an accident, causing death or serious injury.

■When installing the wheel nuts

Tapered portion

●Be sure to install the wheel nuts with the tapered end facing inward. Install- ing the nuts with the tapered end fac- ing outward can cause wheel to break and eventually cause a wheel to come off while driving, which could lead to an accident resulting in death or serious injury.

CTH43AS138

●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.
