●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, see a doctor.

■When working near the electric cooling fans or radiator grille

Vehicles with smart key system: Be sure the “ENGINE START STOP” switch

is OFF. With the “ENGINE START STOP” switch in IGNITION ON mode, the

electric cooling fans may automatically start to run if the air conditioning is on

and/or the coolant temperature is high. (P. 318)

Vehicles without smart key system: Be sure the engine switch is OFF. With

the engine switch in the “ON” position, the electric cooling fans may auto-

matically start to run if the air conditioning is on and/or the coolant tempera-

ture is high. (P. 318)

■Safety glasses

help you to select the proper oil.

314

4-3. Do-it-yourself maintenance

■Engine oil consumption

●The amount of engine oil consumed depends on the oil viscosity, the

quality of the oil and the way the vehicle is driven.

●More oil is consumed under driving conditions such as high speeds and

frequent acceleration and deceleration.

●A new engine consumes more oil.

●When judging the amount of oil consumption, keep in mind that the oil

may have become diluted, making it difficult to judge the true level accu-

rately.

●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per

1000 km)

●If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles

(1000 km), contact your Toyota dealer.

■After changing the engine oil (U.S.A. only)

The engine oil maintenance data should be reset. Perform the following pro-

cedures:

4

1. Turn the “ENGINE START STOP” switch or engine switch OFF with the

trip meter A reading shown.

2. While pressing the trip meter reset button (P. 138), turn the “ENGINE

START STOP” switch or engine switch ON.

3. Continue to press and hold the button until the trip meter displays

000000.

4-3. Do-it-yourself maintenance

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. (P. 411)

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

Visually check the radiator, hoses, coolant reservoir cap, radiator cap, drain

cock and water pump.

4

If you cannot find a leak, have your Toyota dealer test the cap and check for

leaks in the cooling system.

■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

■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.

317

4-3. Do-it-yourself maintenance

NOTICE

■When adding engine 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 damage to parts or paint.

Radiator and condenser

Check the radiator and condenser and remove any foreign objects.

If any of the above parts are extremely dirty or you are not sure of

their condition, have your vehicle checked by your Toyota dealer.

CAUTION

■When the engine is hot

Do not touch the radiator or condenser, as they may be hot and may cause

burns.

val as tire inspection.

Front

■ The tire pressure warning system (if equipped)

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. 379)

The compact spare tire is not equipped with the tire pressure

warning valve and transmitters.

326

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 tire pressure warning valve and transmitter ID codes

must be registered in the tire pressure warning computer and the tire

pressure warning system must be initialized. Have tire pressure

warning valve and transmitter ID codes registered by your Toyota

dealer. (P. 328)

Initializing the tire pressure warning system

The tire pressure warning system must be initialized when changing

the tire size.

When the tire pressure warning system is initialized, the current tire

inflation pressure is set as the pressure benchmark.

4

■ How to initialize the tire pressure warning system

STEP

1

Park the vehicle in a safe place and turn the “ENGINE START

STOP” switch or the engine switch OFF.

While the vehicle is moving, initialization is not performed.

STEP

2

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

tion pressure level. (P. 425)

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 “ENGINE START STOP” switch to IGNITION ON

mode (vehicles with smart key system) or the engine switch to

the “ON” position (vehicles without smart key system).

327

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

Vehicles with smart key system: Wait for a few minutes with

the IGNITION ON mode, and then turn the “ENGINE START

STOP” switch OFF.

Vehicles without smart key system: Wait for a few minutes

with the engine switch in the “ON” position, and then turn the

engine switch to the “LOCK” position.

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.

328

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, or 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 comes on

after blinking for 1 minute to indicate a system malfunction.

■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.

4

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

The effectiveness of snow tires is lost.

■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.

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 for the Gross

Axle Weight Ratings (GAWR), see the Certification Label. (P. 335,

431).

■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.

329

4-3. Do-it-yourself maintenance

■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 restrictions. Snow tires

should be installed on all wheels. (P. 166)

■Initializing the tire pressure warning system

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

level.

■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.

330

4-3. Do-it-yourself maintenance

■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.

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

sure warning light does not flash 3 times.

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

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

minutes.

■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.

These conditions may cause losses in tire air 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 and wheels

Wheels with profile tires like 17-inch tires may cause greater damage

than usual to the tire 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 pressures become low while driving

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

■ Inspection and adjustment procedure

Tire valve

Tire pressure gauge

STEP

1

4

Remove the tire valve cap.

Press the tip of the tire pressure gauge onto the tire valve.

Read the pressure using the graduations of the gauge.

If the tire inflation pressure is not at the recommended level

adjust the pressure.

If you add too much air, press the center of the valve to

lower.

STEP

6

After completing the tire inflation pressure measurement

and adjustment, apply soapy water to the valve and check

for leakage.

Reinstall the tire valve cap.

■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.

336

4-3. Do-it-yourself maintenance

■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 refilling, 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 and 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 pressures that are even just a few pounds off can degrade ride

and handling.

4

●Do not bleed or reduce tire inflation pressure after driving. It is normal

for the 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.

337

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 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.

338

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.

■ 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:

● Wheels of different sizes or types

● Used wheels

● Bent wheels that have been straightened

■ Aluminum wheel precautions

4

● 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

use a plastic or rubber hammer when balancing your wheels.

339

4-3. Do-it-yourself maintenance

■When replacing wheels

The wheels of your Toyota, except for the compact spare tire, 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.

327)

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 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.

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.

Tire pressure warning valves and transmitters may not work properly

with non-genuine wheels.
