Engine coolant

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

Reservoir cap “FULL” “LOW” If the level is on or below the “LOW” line, add coolant up to the “FULL” line.

n If the coolant level drops within a short time after replenishing

Visually check the radiator, hoses, engine coolant reservoir cap, 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.

n Coolant selection

Only use “Toyota Super Long Life Coolant” or 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. (Enabled: -31°F [-35°C])

Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant

and 45% deionized water. (Enabled: -44°F [-42°C])

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

CAUTION

n When the engine is hot

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

4-3. Do-it-yourself maintenance

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 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. 480)

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. 206)

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 (vehicles with a tire pressure warning sys- tem) 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 (vehicles with a tire pressure warning system) Do not use liquid sealants on flat tires.

n Do not use puncture sealant sprays to repair flats (vehicles with a

tire pressure warning system) 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 inset*. Replacement wheels are available at your Toyota dealer. *: Conventionally referred to as “offset”. 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 (vehicles with a tire pressure warning sys-

tem) 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. 370)

CAUTION

n When replacing wheels

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

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

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

NOTICE

n Replacing tire pressure warning valves and transmitters (vehicles

with a tire pressure warning system) l Because tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by your Toyota dealer or other qualified service shop. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer.

l Ensure that only genuine Toyota wheels are used on your vehicle.

Tire pressure warning valves and transmitters may not work properly with non-genuine wheels.

n After a fuse is replaced

If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement. (→P. 400) If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.

n If there is an overload in the circuits

The fuses are designed to blow before the entire wiring harness is damaged.

CAUTION

n To prevent system breakdowns and vehicle fire

Observe the following precautions. Failing to do so may cause damage, and possibly a fire or injury. l Never use a fuse of a higher amperage rating than indicated, or use any

other object in place of a fuse.

l Always use a genuine Toyota fuse or equivalent.

Never replace a fuse with a wire, even as a temporary fix. This can cause extensive damage or even fire.

l Do not modify fuses or the fuse box.

NOTICE

n Before replacing fuses

Have the cause of electrical overload determined and repaired by your Toyota dealer as soon as possible.
