Engine coolant

The coolant level is satisfactory if it is between the “F” and “L” lines on

the reservoir when the engine is cold.

Reservoir cap

“F” line

“L” line

If the level is on or below the “L”

line, add coolant up to the “F” line.

(P. 567)

■ 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.

U.S.A.:

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

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

Canada:

“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deion-

ized water. (Minimum temperature: -44F [-42C])

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 caps, 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 engine coolant reservoir cap or 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.

NOTICE

■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.

Radiator and condenser

Check the radiator and condenser and clear away any foreign objects.

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

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

WARNING

■ When the engine is hot

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

ous injuries, such as burns.

■ Brake fluid can absorb moisture from the air

Excess moisture in the brake fluid can cause a dangerous loss of braking effi-

ciency. Use only newly opened brake fluid.

WARNING

■ When filling the reservoir

Take care as brake fluid can harm your hands and 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.

NOTICE

■ 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 out or when the fluid level in the accumulator is high.

If the reservoir needs frequent refilling, there may be a serious problem.

explosive. Therefore, observe the following before recharging:

● If recharging with the battery installed on the vehicle, be sure to disconnect

the ground cable.

● Make sure the power switch on the charger is off when connecting and dis-

connecting the charger cables to the battery.

■ After recharging/reconnecting the battery (vehicles with a smart key sys-

tem)

● Unlocking the doors using the smart key system may not be possible imme-

diately after reconnecting the battery. If this happens, use the wireless

remote control or the mechanical key to lock/unlock the doors.

● Start the engine with the engine switch in ACCESSORY mode. The engine

may not start with the engine switch turned off. However, the engine will

operate normally from the second attempt.

● The engine switch mode is recorded by the vehicle. If the battery is recon-

nected, the vehicle will return the engine switch mode to the status it was in

before the battery was disconnected. Make sure to turn off the engine

before disconnecting the battery. Take extra care when connecting the bat-

tery if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact your Toyota

dealer.

◆ Installing tire pressure warning valve and transmitters

When replacing the tires or wheels, the tire pressure warning valve

and transmitters must be installed to the wheels which will be

installed to the vehicle.

When new tire pressure warning valve and transmitters are

installed, new ID codes must be registered in the tire pressure

warning computer and the tire pressure warning system must be

initialized. (P. 477)

◆ Initializing the tire pressure warning system

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

lowing circumstances:

● When the tire inflation pressure is changed such as when chang-

ing traveling speed or load weight.

● When the tire inflation pressure is changed such as when the tire

size is changed.

● When rotating the tires.

● Vehicles with a tire inflation pressure display function: After per-

forming the transmitter ID code registration procedure. (P. 477)

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

Park the vehicle in a safe place and stop the engine for 20 min-

utes or more.

The initialization procedure cannot be started while the vehicle is

moving.

Adjust the tire inflation pressure to the specified cold tire inflation

pressure level. (P. 584)

Make sure to adjust the tire pressure to the specified cold tire infla-

tion pressure level. The tire pressure warning system will operate

based on this pressure level.

Start the engine. (P. 209, 211)

◆ Registering ID codes

 Vehicles without a tire inflation pressure display function

Every tire pressure warning valve and transmitter has a unique ID

code. In addition to the set of tire pressure warning system sensor

ID codes initially registered to the vehicle, a second set of ID codes

can be registered.

A second set of tire pressure warning system sensor ID codes can

be registered at your Toyota dealer. When 2 sets of ID codes have

been registered, either ID code set can be selected.

 Vehicles with a tire inflation pressure display function

Every tire pressure warning valve and transmitter has a unique ID

code. When replacing a tire pressure warning valve and transmitter,

it is necessary to register the ID codes.

The ID codes can be registered on

(4.2-inch display) or

(7-

inch display) of the multi-information display.

■ Changing the available set of ID codes (vehicles without a tire

inflation pressure display function)

When 2 sets of ID codes are registered, the corresponding ID code

set for the installed wheels can be selected on

(4.2-inch display)

(7-inch display) of the multi-information display. It is not nec-

essary to reregister the ID codes each time the wheels are

changed.

■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

If the ID codes of the tire pressure warning valve and transmitters are not

registered, the tire pressure warning system will not work properly. In this

case, after driving for about 20 minutes, the tire pressure warning light will

blink for approximately 1 minute and then illuminate 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.

■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 18 or 19-inch wheels)

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 on snowy and/or icy roads and

drive carefully at a speed appropriate for road and weather conditions.

■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. 593)

480

6-3. Do-it-yourself maintenance

■ 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 install-

ing 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 com-

pared 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. 377)

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

The effectiveness of the tires as snow tires is lost.

■ Situations in which the tire pressure warning system may not oper-

ate properly

● In the following situations, the tire pressure warning system may not

operate properly.

• If non-genuine Toyota wheels are used.

• If a tire has been replaced with a tire that is not an OE (Original

Equipment) tire.

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

• If tire chains, etc. are installed.

• If a window tint that affects 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 much higher than the specified level.

• If wheels not equipped with tire pressure warning valve and transmit-

ter are used.

• If the ID codes of the tire pressure warning valve and transmitters are

not registered in the tire pressure warning computer.

6-3. Do-it-yourself maintenance

481

●Performance may be affected in the following situations.

• When driving near a TV tower, electric power plant, gas station, radio

station, large display, airport or other facility that generates strong

radio waves or electrical noise

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

other wireless communication device

Vehicles with a tire inflation pressure display function: If tire position

information is not correctly displayed due to the radio wave conditions,

the display may be corrected by changing the location of the vehicle as

the radio wave conditions may change.

● When the vehicle is stopped, the time taken for the warning to start or

turn off may be longer.

●When the inflation pressure of a tire drops rapidly, for example when a

tire has burst, the warning may not operate.

■Initialization procedure

●Make sure to perform the initialization procedure after adjusting the tire

inflation pressure.

Also, make sure the tires are cold before performing the initialization

procedure or adjusting the tire inflation pressure.

● If the engine switch is turned to the “LOCK” position (vehicles without a

smart key system) or off (vehicles with a smart key system) during ini-

tialization, it is not necessary to restart the initialization procedure from

the beginning as it will begin automatically when the engine switch is

turned back to the “ON” position (vehicles without a smart key system)

or IGNITION ON mode (vehicles with a smart key system).

●If initialization has accidentally been started when it is not necessary,

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

cold and then perform the initialization procedure again.

● Vehicles with a tire inflation pressure display function: While the position

of each tire is being determined and the inflation pressures are not being

displayed on the multi-information display, if the inflation pressure of a

tire drops, the tire pressure warning light will come on.

■ Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accor-

dance 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.

482

6-3. Do-it-yourself maintenance

■If the tire pressure warning system is not initialized properly

 Vehicles without a tire inflation pressure display function

Initialization can be completed in a few minutes. However, in the following

cases, the settings have not been recorded and the system will not oper-

ate properly. If repeated attempts to record tire inflation pressure settings

are unsuccessful, have the vehicle inspected by your Toyota dealer.

●If initialization is attempted and the tire pressure warning light does not

blink 3 times.

●If, when the vehicle has been driven for about 20 minutes after perform-

ing initialization, the tire pressure warning light blinks for approximately

1 minute and then illuminates.

 Vehicles with a tire inflation pressure display function

●In the following situations, initialization may take longer than usual to be

completed or may not be possible. (Usually, the vehicle will need to be

driven for approximately 10 to 30 minutes to complete initialization.)

If initialization is not complete after driving approximately 30 minutes,

continue driving for a while.

• If the vehicle is driven on an unpaved road, it may take longer to com-

plete initialization.

• If the vehicle is backed up while performing initialization, data col-

lected during initialization will be cleared and it will take longer than

normal to complete.

• If the vehicle is driven in heavy traffic or another situation where other

vehicles are driven close by, it may take time for the system to recog-

nize the tire pressure warning valve and transmitters of your vehicle

over those of other vehicles.

If initialization is not complete after driving for approximately 1 hour,

park the vehicle in a safe place for approximately 20 minutes and then

drive the vehicle again.

● In the following situations, initialization will not be started or was not

completed properly and the system will not operate properly. Perform

the initialization procedure again.

• If, when attempting to start initialization, the tire pressure warning light

does not blink 3 times.

• If, when the vehicle has been driven for about 20 minutes after per-

forming initialization, the tire pressure warning light blinks for approxi-

mately 1 minute and then illuminates.

●If initialization cannot be completed after performing the above proce-

dure, contact your Toyota dealer.

6-3. Do-it-yourself maintenance

483

■When registering ID codes (vehicles with a tire inflation pressure dis-

play function)

●Before performing ID code registration, make sure that no wheels with

tire pressure warning valve and transmitters installed are near the vehi-

cle.

●Make sure to initialize the tire pressure warning system after registering

the ID codes. If the system is initialized before registering the ID codes,

the initialized values will be invalid.

●As the tires will be warm when registration is completed, make sure to

allow the tires to cool before performing initialization.

■Canceling ID code registration (vehicles with a tire inflation pressure

display function)

● To cancel ID code registration after it has been started, turn the engine

switch off before driving the vehicle.

If the vehicle is driven after ID code registration is started, to cancel reg-

istration, perform the ID code registration start procedure again and turn

the engine switch off before driving.

●If ID code registration has been canceled, the tire pressure warning light

will blink for approximately 1 minute when the engine switch is turned to

the “ON” position (vehicles without a smart key system) or IGNITION

ON mode (vehicles with a smart key system) and then illuminate. The

tire pressure warning system will be operational when the tire pressure

warning light turns off.

●If the warning light does not turn off even after several minutes have

elapsed, ID code registration may not have been cancelled correctly. To

cancel registration, perform the ID code registration start procedure

again and then turn the engine switch off before driving.

484

6-3. Do-it-yourself maintenance

■If ID codes are not registered properly (vehicles with a tire inflation

pressure display function)

● In the following situations, ID code registration may take longer than

usual to be completed or may not be possible. (Usually, the vehicle will

need to be driven for approximately 10 to 30 minutes to complete ID

code registration.)

If ID code registration is not complete after driving for approximately 30

minutes, continue driving for a while.

• If the vehicle is driven on an unpaved road, it may take longer than

normal to complete registration.

• If the vehicle is backed up while performing registration, data col-

lected during registration will be cleared, and it will take longer than

normal to complete.

• If the vehicle is driven in heavy traffic or another situation where other

vehicles are driven close by, it may take time for the system to recog-

nize the tire pressure warning valve and transmitters of your vehicle

over those of other vehicles.

• If a wheel with a tire pressure warning valve and transmitter installed

is inside or near the vehicle, registration of the ID codes for the

installed wheels may not be possible.

If ID registration is not complete after driving for approximately 1 hour,

park the vehicle in a safe place for approximately 20 minutes and then

perform the ID code registration procedure again.

●In the following situations, ID code registration will not be started or was

not completed properly and the system will not operate properly. Per-

form the ID code registration procedure again.

• If, when attempting to start ID code registration, the tire pressure

warning light does not blink slowly 3 times.

• If, when the vehicle has been driven for about 20 minutes after per-

forming ID code registration, the tire pressure warning light blinks for

approximately 1 minute and then illuminates.

●If ID code registration cannot be completed after performing the above

procedure, contact your Toyota dealer.

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, 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

Do not initialize the tire pressure warning system 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 nor-

mal.

486

6-3. Do-it-yourself maintenance

NOTICE

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

and transmitters and tire valve caps

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

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

warning valve and transmitters may be damaged if not handled cor-

rectly.

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

installed, water may enter the valves of the tire pressure warning valve

and transmitters and the valves may become stuck.

●When replacing tire valve caps, do not replace them with metal caps or

any tire valve caps other than specified, as they may become stuck.

■ To avoid damage to the tire pressure warning valve 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. 475)

■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 18 or 19-inch wheels)

Low profile tires may cause greater damage than usual to the tire wheel

when sustaining 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 potholes, uneven pavement, curbs and other road hazards. Fail-

ure to do so may 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.

Inspection and adjustment procedure

Tire valve

Tire pressure gauge

Remove the tire valve cap.

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

Read the pressure using the gauge gradations.

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 deflate.

After completing the tire inflation pressure measurement and

adjustment, apply soapy water to the valve and check for leakage.

Put the tire valve cap back on.

■ 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 economy

●Reduced driving comfort and poor handling

●Reduced tire life due to wear

●Reduced safety

●Damage to the drivetrain

If a tire needs frequent inflating, have it checked by your Toyota dealer.

6-3. Do-it-yourself maintenance

489

■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 mile or 1.5 km, 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.

● Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is

balanced.

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 on 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.

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 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 plas-

tic or rubber hammer when balancing your wheels.

■When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valve

and transmitters that allow the tire pressure warning system to provide

advance warning in the event of a loss in tire inflation pressure. When-

ever wheels are replaced, tire pressure warning valve and transmitters

must be installed. (P. 475)

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

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.

(P. 553) Installing the nuts with the tapered ends facing 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 seri-

ous 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

accident and resulting in death or serious injury. Remove any oil or

grease from the wheel bolts or wheel nuts.

NOTICE

■Replacing tire pressure warning valve and transmitters

●Because tire repair or replacement may affect the tire pressure warn-

ing valve 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 valve and transmitters at your

Toyota dealer.

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

Tire pressure warning valve and transmitters may not work properly

with non-genuine wheels.
