P.436

If none of the tires are punctured:

Turn the engine switch off then turn it to

IGNITION ON mode. Check if the tire

pressure warning light comes on or blinks.



If the tire pressure warning light blinks for

approximately 1 minute then stays on

There may be a malfunction in the tire

pressure warning system. Have the vehicle

inspected by your Lexus dealer immedi-

ately.



If the tire pressure warning light comes

After the temperature of the tires has

lowered sufficiently, check the inflation

pressure of each tire and adjust them to

the specified level.

If the warning light does not turn off

even after several minutes have

elapsed, check that the inflation pres-

sure of each tire is at the specified level

and perform initialization. (

P.397)

■

The tire pressure warning light may

WARNING

■

If both the ABS and the brake system

warning lights remain on

Stop your vehicle in a safe place immedi-

ately and contact your Lexus dealer.

The vehicle will become extremely

unstable during braking, and the ABS

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.

●

Decelerate to the lowest appropriate

speed as soon as possible. Do not

drive over 50 mph (80 km/h).

●

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. Have the flat tire replaced 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.

WARNING

■

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.)

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 system)

malfunction indicator to indicate when

the system is not operating properly. The

TPMS (tire pressure warning system)

malfunction indicator is combined with

the low tire pressure telltale (tire pres-

sure warning light). When the system

detects a malfunction, the telltale will

flash for approximately one minute and

then remain continuously illuminated.

This sequence will continue upon subse-

quent vehicle start-ups as long as the

malfunction exists. When the malfunction

indicator is illuminated, the system 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 func-

tioning 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 alternate

tires and wheels allow the TPMS (tire

pressure warning system) to continue 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.
