Cleaning and protecting the vehicle exterior

Perform the following to protect the vehicle and maintain it in prime

condition:

● Working from top to bottom, liberally apply water to the vehicle

body, wheel wells and underside of the vehicle to remove any

dirt and dust.

● Wash the vehicle body using a sponge or soft cloth, such as a

chamois.

● For hard-to-remove marks, use car wash soap and rinse thor-

oughly with water.

● Wipe away any water.

● Wax the vehicle when the waterproof coating deteriorates.

If water does not bead on a clean surface, apply wax when the vehicle

body is cool.

■Automatic car washes

●Fold the mirrors and remove the antenna before washing the vehicle.

Start washing from the front of the vehicle. Make sure to re-install the

antenna and extend the mirrors before driving.

●Brushes used in automatic car washes may scratch the vehicle surface

and harm your vehicle’s paint.

●Roof antenna, rear spoiler may not be washable in some automatic car

washes. There may also be an increased risk of damage to vehicle.

437

4-3. Do-it-yourself maintenance

■ Tire pressure warning system

Your vehicle 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. 499)

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 ID codes must be registered in the tire pressure warn-

ing computer and the tire pressure warning system must be initial-

ized. Have tire pressure warning valve and transmitter ID codes

registered by your Toyota dealer. (P. 440)

438

4-3. Do-it-yourself maintenance

Initializing the tire pressure warning system

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

lowing circumstances:

● When rotating front and rear tires which have different tire infla-

tion pressures

● When changing the tire size

When the tire pressure warning system is initialized, the current

tire inflation pressure is set as the benchmark pressure.

■ How to initialize the tire pressure warning system

STEP

1

Park the vehicle in a safe place and turn the “POWER” switch

off.

Initialization cannot be performed while the vehicle is moving.

STEP

2

Adjust the tire inflation pressure to the specified cold tire infla-

tion pressure level. (P. 569)

4

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.

STEP

3

Turn the “POWER” switch to ON mode.

439

4-3. Do-it-yourself maintenance

Press and hold the tire pressure

warning reset switch until the tire

pressure warning light blinks

slowly 3 times.

STEP

STEP

5

Wait for a few minutes with the “POWER” switch in ON mode

and then turn the “POWER” switch off.

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. Have the ID code

registered by your Toyota dealer.

440

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 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.

4

■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.

■Low profile tires (vehicles with 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.

441

4-3. 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. 575)

■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. 317)

442

4-3. Do-it-yourself maintenance

■Initializing the 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.

■If you press 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.

■When 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.

●When operating the tire pressure warning reset switch, the tire pres-

sure warning light does not blink 3 times.

4

●After carrying out the initialization procedure, the tire pressure warn-

ing light blinks for 1 minute then stays on after driving for 20 minutes.

■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 handling characteristics, which may lead to an accident

resulting in death or serious injury.

●Do not mix tires of different makes, models or tread patterns.

Also, do not mix tires of remarkably different treadwear.

●Do not use tire sizes other than those recommended by Toyota.

●Do not mix differently constructed tires (radial, bias-belted or bias-ply

tires).

●Do not mix summer, all season and snow tires.

●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.

■When initializing the tire pressure warning system

4

Do not operate the tire pressure warning reset switch without first adjust-

ing the tire inflation pressure to the specified level. Otherwise, the tire

pressure 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 nor-

mal.

445

4-3. Do-it-yourself maintenance

NOTICE

■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 transmitters 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 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. 438)

■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.

■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:

●Be sure to use proper tire inflation pressure. If tires are under-inflated,

they may be damaged more severely.

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

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

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

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

■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 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.

4

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.

449

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.

450

4-3. Do-it-yourself m aintenanc e

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

4

■ 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.

● Use only Toyota genuine balance weights or equivalent and a

plastic or rubber hammer when balancing your wheels.

451

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 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. 438)

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

tubeless tire. Doing so may result in an accident, causing death or seri-

ous injury.

■When installing the wheel nuts

●Be sure to install the wheel nuts with

the tapered ends facing inward.

Installing the nuts with the tapered

ends facing outward can cause the

wheel to break and eventually cause

Tapered

the wheel to come off while driving,

which could lead to an accident

resulting in death or serious injury.

portion

ITI41P007

●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.

452

4-3. Do-it-yourself maintenance

CAUTION

■Use of defective wheels prohibited

Do not use cracked or deformed wheels.

Doing so could cause the tire to leak air during driving, possibly causing

an accident.

NOTICE

■Replacing tire pressure warning valves and transmitters

●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.

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

■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. 467)

●If the replaced fuse blows again, have the vehicle inspected by your

Toyota dealer.

■If there is an overload in a circuit

The fuses are designed to blow, protecting the wiring harness from damage.

■When replacing light bulbs

Toyota recommends that you use genuine Toyota products designed for this

vehicle. Because certain bulbs are connected to circuits designed to prevent

overload, non-genuine parts or parts not designed for this vehicle may be

unusable.

CAUTION

4

■To prevent system breakdowns and vehicle fire

Observe the following precautions.

Failure to do so may cause damage, and possibly a fire or injury.

●Never use a fuse of a higher amperage rating than that indicated, or use

any other object in place of a fuse.

●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.

●Do not modify the fuses or fuse boxes.

■Fuse box near the power control unit

Never check or replace the fuses as there are high voltage parts and wiring

near the fuse box.

Doing so may cause electric shock, resulting in death or serious injury.
