interval

You should check tire inflation pres-

sure 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

●

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 vehi-

cle 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.

set.

Toyota does not recommend
using the following:



Wheels of different sizes or
types



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. (

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.

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 acci-

dent, causing death or serious

injury.

■

When installing the wheel

nuts

Never use oil or grease on the

wheel bolts or wheel nuts.

Oil and grease may cause the

wheel nuts to be excessively tight-

ened, 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.

■

Use of defective wheels pro-

hibited

Do not use cracked or deformed

wheels. Doing so could cause the

tire to leak air during driving, pos-

sibly causing an accident.

NOTICE

■

Replacing tire pressure warn-

ing valves and transmitters

●

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.
