system may fail, which could cause an

accident resulting in death or serious

injury.

■

When the electric power steering

system warning light comes on

When the light comes on yellow, the

assist to the power steering is restricted.

When the light comes on red, the assist

to the power steering is lost and handling

operations of the steering wheel become

extremely heavy.

When steering wheel operations are

heavier than usual, grip the steering

wheel firmly and operate it using more

force than usual.

■

If the tire pressure warning light

comes on

Be sure to observe the following precau-

tions.

Failure to do so could cause a loss of

vehicle control and result in death or

serious injury.

●

Stop your vehicle in a safe place as

soon as possible. Check and adjust the

tire inflation pressure immediately.

●

If the tire pressure warning light comes

on even after tire inflation pressure

adjustment, it is probable that you have

a flat tire. Check the tires. If a tire is flat,

change it with the spare tire and have

the flat tire repaired by the nearest

Lexus dealer.

●

Avoid abrupt maneuvering and brak-

ing.

If the vehicle tires deteriorate, you

could lose control of the steering

wheel or the brakes.

■

If a blowout or sudden air leakage

should occur

The tire pressure warning system may

not activate immediately.

■

Maintenance of the tires

Each tire, including the spare (if pro-

vided), should be checked monthly when

cold and inflated to the inflation pressure

recommended by the vehicle manufac-

turer on the vehicle placard or tire infla-

tion pressure label (tire and load

information label). (If your vehicle has

tires of a different size than the size indi-

cated on the vehicle placard or tire infla-

tion pressure label [tire and load

information label], you should determine

the proper tire inflation pressure for

those tires.)

356

7-2. Steps to take in an emergency

WARNING

As an added safety feature, your vehicle

has been equipped with a tire pressure

monitoring system (TPMS-tire pressure

warning system) that illuminates a low

tire pressure telltale (tire pressure warn-

ing light) when one or more of your tires

is significantly under-inflated. Accord-

ingly, when the low tire pressure telltale

(tire pressure warning light) illuminates,

you should stop and check your tires as

soon as possible, and inflate them to the

proper pressure. Driving on a signifi-

cantly under-inflated tire causes the tire

to overheat and can lead to tire failure.

Under-inflation also reduces fuel effi-

ciency and tire tread life, and may affect

the vehicle’s handling and stopping abil-

ity.

Please note that the TPMS (tire pressure

warning system) is not a substitute for

proper tire maintenance, and it is the

driver’s responsibility to maintain correct

tire pressure, even if under-inflation has

not reached the level to trigger illumina-

tion of the TPMS low tire pressure telltale

(tire pressure warning light).

Your vehicle has also been equipped

with a TPMS (tire pressure warning sys-

tem) malfunction indicator to indicate

when the system is not operating prop-

erly. The TPMS (tire pressure warning

system) malfunction indicator is com-

bined with the low tire pressure telltale

(tire pressure warning light). When the

system detects a malfunction, the telltale

will flash for approximately one minute

and then remain continuously illumi-

nated. This sequence will continue upon

subsequent vehicle start-ups as long as

the malfunction exists. When the mal-

function indicator is illuminated, the sys-

tem may not be able to detect or signal

low tire pressure as intended.

TPMS (tire pressure warning system)

malfunctions may occur for a variety of

reasons, including the installation of

replacement or alternate tires or wheels

on the vehicle that prevent the TPMS

(tire pressure warning system) from

functioning properly. Always check the

TPMS (tire pressure warning system)

malfunction telltale after replacing one

or more tires or wheels on your vehicle

to ensure that the replacement or alter-

nate tires and wheels allow the TPMS

(tire pressure warning system) to con-

tinue to function properly.

NOTICE

■

To ensure the tire pressure warning

system operates properly

Do not install tires with different specifi-

cations or makers, as the tire pressure

warning system may not operate prop-

erly.

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 precautions

could cause the wheel nuts to loosen

and the tire to fall off, resulting in death

or serious 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, lead-

ing 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 a serious accident.

Remove any oil or grease from the

wheel bolts or wheel nuts.
