7-3. Do-it-yourself maintenance

WARNING

The engine compartment contains many mechanisms and fluids that may

move suddenly, become hot, or become electrically energized. To avoid death

or serious injury, observe the following precautions.

■When working on the engine compartment

●Keep hands, clothing and tools away from the moving fan and engine

drive belt.

●Be careful not to touch the engine, radiator, exhaust manifold, etc., right

after driving as they may be hot. Oil and other fluids may also be hot.

●Do not leave anything that may burn easily, such as paper and rags, in the

engine compartment.

●Do not smoke, cause sparks or expose an open flame to fuel or the bat-

tery. Fuel and battery fumes are flammable.

●Be extremely cautious when working on the battery. It contains poisonous

and corrosive sulfuric acid.

●Take care because brake fluid can harm your hands or eyes and damage

painted surfaces. If fluid gets on your hands or in your eyes, flush the

affected area with clean water immediately.

If you still experience discomfort, consult a doctor.

■When working near the electric cooling fan or radiator grille

Be sure the engine switch is in the “LOCK” position. With the engine switch

in the “ON” position, the electric cooling fans may automatically start to run

if the air conditioning is on and/or the coolant temperature is high. (→P. 252)

■Safety glasses

Wear safety glasses to prevent flying or falling material, fluid spray, etc.,

from getting in your eyes.

7

NOTICE

■If you remove the air cleaner filter

Driving with the air cleaner filter removed may cause excessive engine wear

due to dirt in the air.

■If the fluid level is low or high

It is normal for the brake fluid level to go down slightly as the brake pads

wear or when the fluid level in the accumulator is high.

If the reservoir needs frequent refilling, it may indicate a serious problem.

7-3. Do-it-yourself maintenance

■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.

“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-

ized water. (Minimum temperature: -35°C [-31°F])

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 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.

WARNING

■When the engine 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 serious injuries, such as burns.

■When replacing the coolant

To avoid coolant spilling on the alternator, do not remove the upper radiator

hose from engine side (remove from the radiator side). Coolant spilled on

the alternator will cause corrosion of the coil and a fire.

NOTICE

7

■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.

To equalize tire wear and help extend tire life, Toyota recommends

that tire rotation is carried out approximately every 5000 km

(3000 miles).

Tire pressure warning system (if equipped)

Your vehicle is equipped with a tire pressure warning system that uses

tire pressure warning valves and transmitters to detect low tire infla-

tion pressure before serious problems arise.

7

If the tire pressure drops below a predetermined level, the driver is

warned by a warning light. (→P. 309)

Installing tire pressure warning valves and transmitters (vehicles

with a tire pressure warning system)

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 warning com-

puter and the tire pressure warning system must be initialized. Have

tire pressure warning valve and transmitter ID codes registered by

your Toyota dealer. (→P. 262)

262

7-3. Do-it-yourself maintenance

Initializing the tire pressure warning system (vehicles with a 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

1

Park the vehicle in a safe place and turn the engine switch to the

“LOCK” position.

Initialization cannot be performed while the vehicle is moving.

2

Adjust the tire inflation pressure to the specified cold tire inflation

pressure level. (→P. 346)

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.

3

Turn the engine switch to the “ON” position.

4

Press and hold the tire pres-

sure warning reset switch

until the tire pressure warn-

ing light blinks slowly 3 times.

KBAV730504E

5

Wait for a few minutes with the engine switch in the “ON” position

and then turn the engine switch to the “ACC” or “LOCK” position.

Registering ID codes (vehicles with a tire pressure warning sys-

tem)

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.

263

7-3. Do-it-yourself maintenance

■When to replace your vehicle’s tires

Tires should be replaced if:

●The treadwear indicators are showing on a tire.

●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 (vehicles with a tire pressure warning sys-

tem)

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 10 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.

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

The effectiveness of the tires as snow tires is lost.

■Routine tire inflation pressure checks (vehicles with a tire pressure

warning system)

The tire pressure warning system does not replace routine tire inflation pres-

sure checks. Make sure to check tire inflation pressure as part of your routine

of daily vehicle checks.

■Initializing the tire pressure warning system (vehicles with a tire pres-

sure warning system)

7

Initialize the system with the tire inflation pressure adjusted to the specified

level.

■Situations in which the tire pressure warning system may not operate

properly (if equipped)

●In the following cases, the tire pressure warning system may not operate

properly.

• If non-genuine Toyota wheels are used.

• A tire has been replaced with a tire that is not an OE (Original Equipment)

tire.

• A tire has been replaced with a tire that is not of the specified size.

• Tire chains, etc., are equipped.

• An auxiliary-supported run-flat tire is equipped.

• If a window tint that affects the radio wave signals is installed.

• If there is a lot of snow or ice on the vehicle, particularly around the

wheels or wheel housings.

• If the tire inflation pressure is extremely higher than the specified level.

264

7-3. Do-it-yourself maintenance

• If the spare tire is in a location subject to poor radio wave signal recep-

tion.

• If a large metallic object which can interfere with signal reception is put

near the spare tire.

• If a wheel, not equipped with a tire pressure warning valve and transmit-

ter, is used.

• If the ID code on the tire pressure warning valves and transmitters is not

registered in the tire pressure warning computer.

●Performance may be affected in the following situations.

• Near a TV tower, electric power plant, gas station, radio station, large dis-

play, airport or other facility that generates strong radio waves or electri-

cal noise

• When carrying a portable radio, cellular phone, cordless phone or other

wireless communication device

●When the vehicle is parked, the time taken for the warning to start or go off

could be extended.

●When tire inflation pressure declines rapidly for example when a tire has

burst, the warning may not function.

■The initialization operation (vehicles with the tire pressure warning sys-

tem)

●Make sure to carry out initialization after adjusting the tire inflation pressure.

Also, make sure the tires are cold before carrying out initialization or tire

inflation pressure adjustment.

●If you have accidentally turned the engine switch to the “LOCK” position

during initialization, it is not necessary to press the reset switch again as ini-

tialization will restart automatically when the engine switch has been turned

to the “ON” position for the next time.

●If you accidentally press the reset switch when initialization is not necessary,

adjust the tire inflation pressure to the specified level when the tires are

cold, and conduct initialization again.

■Warning performance of the tire pressure warning system (if equipped)

The warning of the tire pressure warning system will change in accordance

with the conditions under which it was initialized. For this reason, the system

may give a warning even if the tire pressure does not reach a low enough

level, or if the pressure is higher than the pressure that was adjusted to when

the system was initialized.

265

7-3. Do-it-yourself maintenance

■When initialization of the tire pressure warning system has failed (vehi-

cles with a tire pressure warning system)

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.

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

warning light does not blink 3 times.

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

completed, the warning light comes on after blinking for 1 minute.

WARNING

■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 and all season 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 (vehicles with a tire

pressure warning system)

Do not operate the tire pressure warning reset switch without first adjusting

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 normal.

267

7-3. Do-it-yourself maintenance

NOTICE

■Driving on rough roads

Take particular care when driving on roads with loose surfaces or potholes.

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.

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

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

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

transmitters and tire valve caps (vehicles with a tire pressure warning

system)

●When removing or fitting the wheels, tires or the tire pressure warning

valves and transmitters, contact your Toyota dealer as the tire pressure

warning valves and transmitters may be damaged if not handled correctly.

●Make sure to install the tire valve caps. If the tire valve caps are not

installed, water could enter the tire pressure warning valves and the tire

pressure warning valves could be bound.

●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

(vehicles with a tire pressure warning system)

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. After

use of liquid sealant, make sure to replace the tire pressure warning valve

and transmitter when repairing or replacing the tire. (→P. 261)

7-3. Do-it-yourself maintenance

Tire inflation pressure

Make sure to maintain proper tire inflation pressure. Tire infla-

tion pressure should be checked at least once per month. How-

ever, Toyota recommends that tire inflation pressure be checked

once every two weeks. (→P. 346)

■Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following:

●Reduced fuel economy

●Reduced driving comfort and poor handling

●Reduced tire life due to wear

●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 1.5 km or 1 mile, you will get an accurate cold tire inflation

pressure reading.

●Always use a tire pressure gauge.

It is difficult to judge if a tire is properly inflated based only on its appear-

ance.

●It is normal for the tire inflation pressure to be higher after driving as heat is

generated in the tire. Do not reduce tire inflation pressure after driving.

269

7-3. Do-it-yourself maintenance

WARNING

■Proper inflation is critical to save tire performance

Keep your tires properly inflated.

If the tires are not properly inflated, the following conditions may occur

which could lead to an accident resulting in death or serious injury:

●Excessive wear

●Uneven wear

●Poor handling

●Possibility of blowouts resulting from overheated tires

●Air leaking from between tire and wheel

●Wheel deformation and/or tire damage

●Greater possibility of tire damage while driving (due to road hazards,

expansion joints, sharp edges in the road, etc.)

NOTICE

■When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on.

If a valve cap is not installed, dirt or moisture may get into the valve and

cause an air leak, resulting in decreased tire inflation pressure.

7

270

7-3. 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 (if equipped)

● 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 1600 km (1000 miles).

● Use only Toyota genuine balance weights or equivalent and use a

plastic or rubber hammer when balancing your wheels.

■When replacing wheels (vehicles with a tire pressure warning system)

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 transmitters must be

installed. (→P. 261)

WARNING

■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

●Be sure to install the wheel nuts with the

tapered ends facing inward. Installing

the nuts with the tapered ends facing

Tapered

portion

outward can cause the wheel to break

and eventually cause the wheel to come

off while driving, which could lead to an

accident resulting in death or serious

injury.

●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 acci-

dent and resulting in death or serious injury. Remove any oil or grease

from the wheel bolts or wheel nuts.

■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 (vehicles with

a tire pressure warning system)

●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.

●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.
