WARNING

■

Replacing a flat tire

●

Do not touch the disc wheels or

the area around the brakes

immediately after the vehicle

has been driven.

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.

●

Failure to follow these precau-

tions could cause the wheel

bolts to loosen and the tire to fall

off, resulting in death or serious

injury.

• Never apply oil or grease to the

wheel bolts or their contact sur-
face on the wheel

Doing so may cause the wheel
bolts to be tightened exces-
sively, leading to damage to the
wheel bolts, the threaded por-
tion the wheel bolts install to

or the wheel.
Also, the wheel bolts may come
loose, possibly leading to the
wheel coming off, causing a
serious accident.
If oil or grease is attached to
either of these parts, remove it.

●

When installing a wheel, use the

same wheel bolts that were

removed with the wheel. Also,

do not use any wheel bolts

other than Toyota Genuine

wheel bolts.

• If a wheel bolt hole in a wheel or

the threads of a wheel bolt or

the wheel hub are deformed,

cracked, rusty or otherwise

damaged, have the vehicle

inspected by your Toyota

dealer.

■

When tightening the wheel

bolts

Do not tighten the wheel bolts

excessively.

Doing so may cause the wheel

bolts, the threads of the wheel

hub, or the wheel to be damaged.

■

Replacing a flat tire for vehi-

cles with power back door

In cases such as when replacing

tires, make sure to cancel the

power back door system

(

Effects of incorrect tire inflation

pressure

Driving with incorrect tire inflation

pressure may result in the following:

●

Reduced electricity consumption

●

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 pres-

sure, 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

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.

●

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 seri-

ous 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 dam-

age while driving (due to road

hazards, expansion joints,

sharp edges in the road, etc.)

NOTICE

■

When inspecting and adjust-

ing 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.

WARNING

■

When replacing wheels

●

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.

●

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.

■

Wheel bolts

Observe the following precautions

to reduce the risk of death or seri-

ous injury:

●

Do not over tighten.

●

Never use oil or grease on the

wheel bolts. Oil and grease may

cause the wheel bolts to be

excessively tightened, leading

to bolt or disc wheel damage. In

addition, the oil or grease can

cause the wheel bolts to loosen

and the wheel may fall off, caus-

ing a serious accident. Remove

any oil or grease from the wheel

bolts.

●

If there are any cracks or defor-

mations in the wheel bolts, or if

the surface treatment becomes

worn, have the wheel bolts

replaced at your Toyota dealer.

Failure to follow these precau-

tions could cause the wheel

bolts to loosen and the tire to fall

off, resulting in death or serious

injury.

■

Use of defective wheels pro-

hibited

Do not use cracked or deformed

wheels.
Doing so could cause the tire to

leak air during driving, possibly

causing an accident.
