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 hybrid system 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.

NOTICE

n When adding the coolant

Coolant is neither plain water not straight antifreeze. The correct mixture of water and anti freeze must be used to provide proper lubrication, corrosion protection and cooling. Be sure to read the antifreeze or coolant label.

n The tire pressure warning system

Your Toyota is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire inflation pressure before serious problems arise. (→P. 509) The compact spare tire is not equipped with a tire pressure warning valve and transmitter.

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 Toyota dealer. (→P. 456)

Initializing the tire pressure warning system

n The tire pressure warning system must be initialized in the fol-

lowing circumstances l When rotating the tires on vehicles differing with front and rear

tire inflation pressures.

l When changing the tire inflation pressure by changing traveling

speed or load weight, etc.

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

454

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

n How to initialize the tire pressure warning system STEP 1

Park the vehicle in safe place and turn the “POWER” switch OFF. While the vehicle is moving, initialization is not performed. Adjust the tire inflation pressure to the specified cold tire infla- tion pressure level. (→P. 575) 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 “POWER” switch to ON mode.

STEP 2

STEP 3

STEP 4

Push and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly 3 times.

STEP 5

Wait for a few minutes with the ON mode, and then turn “POWER” switch OFF.

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

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.

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 regis- tered, 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.

456

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

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 Low profile tires (vehicles with 17-inch tires)

Generally, low profile tires will wear more rapidly and tire grip performance 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.

n 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. 581)

457

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

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. 270)

458

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

n Initializing the tire pressure warning system

Initialize the tires 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 a few minutes. However, in the following 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 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.

CAUTION

n 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 han- dling characteristics, which may lead to an accident resulting in death or serious injury. l Do not mix tires of different makes, models or tread patterns.

Also, do not mix tires of remarkably different treadwear.

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

tires).

l Do not mix summer, all season and winter tires. l 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.

n When initializing the tire pressure warning system

Do not push the tire pressure warning reset switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pres- sure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.

4-3. Do-it-yourself maintenance

NOTICE

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

and transmitters and tire valve caps l 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 cor- rectly.

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

those specified. The cap may become stuck.

n 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. 454)

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 Low profile tires (vehicles with 17-inch tires)

Low profile tires may cause greater damage than usual to the wheel when receiving impact from the road surface. Therefore pay attention to the following: l Be sure to use proper tire inflation pressure. If tires are under-inflated,

they may be damaged more severely.

l Avoid pot holes, uneven pavement, curbs and other road hazards.

Failure to do so can lead to severe tire and wheel damage.

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.

465

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

CAUTION

n 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. l Excessive wear l Uneven wear l Poor handling l Possibility of blowouts resulting from overheated tires l Poor sealing of the tire bead l Wheel deformation and/or tire separation l A greater possibility of tire damage from road hazards

NOTICE

n When inspecting and adjusting tire inflation pressure

Be sure to reinstall the tire valve caps. 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 have been lost, replace them as soon as possible.

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 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.

467

PRIUS_U (OM47685U) DVD

4-3. Do-it-yourself maintenance

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. 454)

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 death or seri- ous injury.

NOTICE

n Replacing tire pressure warning valves and transmitters

l Because tire repair or replacement may affect the tire pressure warn- ing 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. 481) 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, protecting the wiring harness from damage.

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.
