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

Visually check the radiator, hoses, engine coolant filler cap, radiator cap, drain cock and water pump. If you cannot find a leak, have your Toyota dealer pressure 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 coolant is hot

Do not remove the radiator 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 If you spill coolant

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

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. 429) The compact spare tire is not equipped with a tire pressure warning valve and transmitter.

379

PRIUS_U_(L/O_0802)

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 sensor ID codes must be registered in the tire pressure warning computer and tire pressure warning system must be initial- ized.

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.

380

PRIUS_U_(L/O_0802)

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 to OFF mode. While the vehicle is moving, initialization is not performed. Adjust the tire inflation pressure to the specified cold tire infla- tion pressure level. (→P. 470) 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.

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 about 20 minutes, the tire pressure warning light blinks (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 maximum load of the replaced 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. As for the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight Ratings (GAWR), see the Certification Label. (→P. 388, 474).

PRIUS_U_(L/O_0802)

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. 177) n Initializing the tire pressure warning system

Initialize the tires with the tire inflation pressure adjusted to the specified level.

383

PRIUS_U_(L/O_0802)

4-3. Do-it-yourself maintenance

n If you push the tire pressure reset switch accidentally

If initialization is performed, adjust the tire inflation pressure to the speci- fied level and initialize the 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 follow- ing 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 warning light does not flash (The tires cannot be initializes whiled the vehicle is moving.).

l After driving for a certain period of time since the initialization has

been completed, the warning light flashes.

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.

4-3. Do-it-yourself maintenance

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.

390

PRIUS_U_(L/O_0802)

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.

391

PRIUS_U_(L/O_0802)

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 offset. Replacement wheels are available at your Toyota dealer. 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.

392

PRIUS_U_(L/O_0802)

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 switched over from the old wheels. (→P. 380)

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. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer.

CAUTION

n Replacing light bulbs

l Turn off the headlights. Do not attempt to replace the bulb immediately

after turning off the headlights. The bulbs become very hot and may cause burns.

l Do not touch the glass portion of the light bulb with bare hands. Hold the

bulb by the plastic or metal portion. If the bulb is scratched or dropped it may blow out or crack.

l Fully install light bulbs and any parts used to secure them. Failing to do so may result in heat damage, fire, or water entering the headlight unit. This may damage the headlights or cause condensation to build up on the lens. l Do not take apart or repair the low beam discharge headlight bulbs, con-

nectors, power supply circuits, or related components. Doing so could result in electric shock and death or serious injury.

n High-intensity discharge (HID) headlights

l Contact your Toyota dealer before replacing high-intensity discharge

headlights (including light bulbs).

l Do not touch the high-intensity discharge headlight’s high voltage socket when the headlights are turned on. An extremely high voltage of 20000V will be discharged and could result in serious injury or death by electric shock.

n To prevent damage or fire

Make sure bulbs are fully seated and locked.

5-1. Essential information If your vehicle needs to be towed

If towing is necessary, we recommend having your vehicle towed by your Toyota dealer or a commercial towing service, using a lift-type truck or a flat bed truck. Use a safety chain system for all towing, and abide by all state/pro- vincial and local laws. If towing from the front, the vehicle’s rear wheel and axles must be in good condition. (→P. 420) If they are damaged, use a towing dolly or flat bed truck.

Before towing

The following may indicate a problem with your transmission. Contact your Toyota dealer before towing. l The hybrid system is running, but the vehicle will not move. l The vehicle makes an abnormal sound.

Emergency towing

If a tow truck is not available, in an emergency your vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet. This should only attempted on hard, surfaced roads for short distances below 18 mph (30km/h). A driver must be in the vehicle to steer and operate the brakes. The vehicle’s wheels, drive train, axles, steering and brakes must be in good condition.
