NOTICE

■When adding coolant

■Coolant selection

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.

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%

deionized water. (Minimum tem-

perature: -31°F [-35°C])

■If you spill coolant

Be sure to wash it off with water to

prevent it from damaging parts or

paint.

Canada:

“Toyota Super Long Life Coolant” is

a mixture of 55% coolant and 45%

deionized water. (Minimum tem-

perature: -44°F [-42°C])

Checking the radiator and

condenser

For more details about coolant, con-

tact your Toyota dealer.

Check the radiator and con-

denser, and clear away any for-

eign 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.

■If the coolant level drops within

a short time of replenishing

Visually check the radiators, hoses,

engine/power control unit 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 sys-

tem.

indicators are showing on a tire.

■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

■Tire types

●Summer tires

Summer tires are high-speed per-

formance tires best suited to high-

way driving under dry conditions.

Since summer tires do not have

the same traction performance as

snow tires, summer tires are inad-

equate for driving on snow-cov-

ered or icy roads. For driving on

snow-covered roads or icy roads,

the use of snow tires is recom-

mended. When installing snow

tires, be sure to replace all four

tires.

●A tire goes flat repeatedly or can-

not be properly repaired due to

the size or location of a cut or

other damage

If you are not sure, consult your

Toyota dealer.

■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.

●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 sum-

mer tires in highway driving.

■Low profile tires (vehicles with

195/50R19 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 on snowy and/or icy roads and

drive carefully at a speed appropri-

ate for road and weather conditions.

■Maximum load of tire

●Snow tires

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 driving on snow-covered

roads or icy roads, we recom-

mend using snow tires. If you

need snow tires, select tires of the

same size, construction 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.429)

For the GAWR, see the Certification

Label. For the maximum load of the

tire, see the load limit at maximum

cold tire inflation pressure men-

tioned on the sidewall of the tire.

(P.609)

515

7-3. Do-it-yourself maintenance

■If the tread on snow tires wears

down below 0.16 in. (4 mm)

NOTICE

■Driving on rough roads

The effectiveness of the tires as

snow tires is lost.

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.

WARNING

■When inspecting or replacing

tires

Observe the following precautions

to prevent accidents.

Failure to do so may cause dam-

age to parts of the drivetrain as

well as dangerous handling char-

acteristics, which may lead to an

accident resulting in death or seri-

ous injury.

■Low profile tires (vehicles

with 195/50R19 tires)

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:

●Do not mix tires of different

makes, models or tread pat-

terns.

Also, do not mix tires of remark-

ably different treadwear.

●Be sure to use proper tire infla-

tion pressure. If tires are under-

inflated, they may be damaged

more severely.

●Do not use tire sizes other than

those recommended by Toyota.

●Do not mix differently con-

structed tires (radial, bias-belted

or bias-ply tires).

●Avoid potholes, uneven pave-

ment, curbs and other road haz-

ards. Failure to do so may lead

to severe tire and wheel dam-

age.

●Do not mix summer, all season

and snow tires.

7

■If tire inflation pressure of

each tire becomes low while

driving

●Do not use tires that have been

used on another vehicle.

Do not use tires if you do not

know how they were used previ-

ously.

Do not continue driving, or your

tires and/or wheels may be

ruined.

Tire rotation

Rotate the tires in the order

shown.

To equalize tire wear and extend

tire life, Toyota recommends that

tire rotation is carried out at the

same interval as tire inspection.

■Routine tire inflation pressure

checks

●Performance may be affected in

the following situations.

• Near a TV tower, electric power

plant, gas station, radio station,

large display, airport or other facil-

ity that generates strong radio

waves or electrical noise

• When carrying a portable radio,

cellular phone, cordless phone or

other wireless communication

device

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.

■Tire inflation pressure

●It may take a few minutes to dis-

play the tire inflation pressure

after the power switch is turned to

ON.

It may also take a few minutes to

display the tire inflation pressure

after inflation pressure has been

adjusted.

If tire position information is not cor-

rectly 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.

●Tire inflation pressure changes

with temperature. The displayed

values may also be different from

the values measured using a tire

pressure gauge.

●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 warning of the tire pressure

warning system will change in

accordance with driving conditions.

For this reason, the system may

give a warning even if the tire pres-

sure 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.

●When removing or fitting the

wheels, tires or the tire pressure

warning valves and transmit-

ters, contact your Toyota dealer

as the tire pressure warning

valves and transmitters may be

damaged if not handled cor-

rectly.

Installing tire pressure

warning valves and trans-

mitters

●Make sure to install the tire

valve caps. If the tire valve caps

are not installed, water could

enter the tire pressure warning

valves, corrode the valve, and

cause sticking and air leaks.

When replacing tires or wheels,

tire pressure warning valves and

transmitters must also be

installed.

●When replacing tire valve caps,

do not use tire valve caps other

than those specified. The cap

may become stuck.

When new tire pressure warning

valves and transmitters are

installed, new ID codes must be

registered in the tire pressure

warning computer. (P.522)

■To avoid damage to the tire

pressure warning valves and

transmitters

When a tire is repaired with liquid

sealants, the tire pressure warn-

ing valve and transmitter may not

operate properly. If a liquid seal-

ant 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.518)

■When replacing the 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. In this

case, after driving for about 20 min-

utes, the tire pressure warning light

blinks for 1 minute and stays on to

indicate a system malfunction.

WARNING

■Replacing a flat tire

●Do not touch the disc wheels or

the area around the brakes

immediately after the vehicle

has been driven.

• Never use oil or grease on the

wheel bolts or wheel nuts.

After the vehicle has been

driven the disc wheels and the

area around the brakes will be

extremely hot. Touching these

areas with hands, feet or other

body parts while changing a tire,

etc. may result in burns.

Oil and grease may cause the

wheel nuts to be excessively

tightened, leading to bolt or disc

wheel damage. Remove any oil

or grease that has adhered

when installing the wheel nuts.

• Have the wheel nuts tightened

with a torque wrench to 76 ft•lbf

(103 N•m, 10.5 kgf•m) as soon

as possible after changing

wheels.

• After replacing a tire, check the

tightening torque as soon as

possible. If you cannot confirm

the tightening torque yourself,

have the vehicle inspected at

your Toyota dealer.

• When installing a tire, only use

wheel nuts that have been spe-

cifically designed for that wheel.

• If there are any cracks or defor-

mations in the bolt screws, nut

threads or bolt holes of the

wheel, have the vehicle

inspected by your Toyota

dealer.

• Do not attach a heavily dam-

aged wheel ornament, as it may

fly off the wheel while the vehi-

cle is moving.

■Replacing a flat tire for vehi-

cles with power back door

In cases such as when replacing

cold tire inflation pressure reading.

3 Read the pressure using the

gauge gradations.

4 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.

●Always use a tire pressure gauge.

It is difficult to judge if a tire is

properly inflated based only on its

appearance.

●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.

5 After completing the tire infla-

tion pressure measurement

and adjustment, apply soapy

water to the valve and check

for leakage.

●Never exceed the vehicle capacity

weight. Passengers and luggage

weight should be placed so that

the vehicle is balanced.

6 Put the tire valve cap back

on.

■Tire inflation pressure check

interval

You should check tire inflation pres-

sure every two weeks, or at least

once a month.

Wheels

WARNING

■Proper inflation is critical to

save tire performance

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.

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 seri-

ous injury:

●Excessive wear

●Uneven wear

●Poor handling

Wheel selection

When replacing wheels, care

should be taken to ensure that

they are equivalent to those

removed in load capacity, diam-

●Possibility of blowouts resulting

from overheated tires

●Air leaking from between tire

and wheel

eter, rim width and inset^*.

●Wheel deformation and/or tire

damage

Replacement wheels are avail-

able at your Toyota dealer.

●Greater possibility of tire dam-

age while driving (due to road

hazards, expansion joints,

types

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.

 Used wheels

 Bent wheels that have been

straightened

■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 pres-

sure. Whenever wheels are

replaced, tire pressure warning

valves and transmitters must be

installed. (P.531, 534)

WARNING

NOTICE

■When replacing wheels

■Replacing tire pressure warn-

ing valves and transmitters

●Do not use wheels that are a dif-

ferent size from those recom-

mended in the Owner’s Manual,

as this may result in a loss of

handling control.

●Because tire repair or replace-

ment may affect the tire pres-

sure 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 transmit-

ters at your Toyota dealer.

●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 serious injury.

■When installing the wheel

●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.

nuts

●Be sure to install the wheel nuts

with the tapered ends facing

inward. (P.530)

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 result-

ing in death or serious injury.

Aluminum wheel precau-

tions

 Use only Toyota wheel nuts

and wrenches designed for

use with your aluminum

wheels.

●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.

 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 of defective wheels pro-

hibited

Do not use cracked or deformed

wheels.

 Use only Toyota genuine bal-

ance weights or equivalent

and a plastic or rubber ham-

mer when balancing your

wheels.

Doing so could cause the tire to

leak air during driving, possibly

causing an accident.
