Follow the procedure below to restart
the engine after the system is activated.

Turn the engine switch to ACCES-
SORY mode or turn it off.

Restart the engine.

Fuel pump shut off system

supply of fuel to the engine.

Restarting the engine

NOTICE

Before starting the engine

Inspect the ground under the vehicle.

If you find that fuel has leaked onto the

ground, the fuel system has been dam-

■

When the tire pressure warning light

comes on

Check the tire inflation pressure and adjust

to the appropriate level. Pushing the tire

pressure warning reset switch will not turn

off the tire pressure warning light.

■

The tire pressure warning light may

come on due to natural causes

The tire pressure warning light may come

on due to natural causes such as natural air

leaks and tire inflation pressure changes

caused by temperature. In this case, adjust-

ing the tire inflation pressure will turn off the

warning light (after a few minutes).

■

When a tire is replaced with the spare

tire

The spare tire is not equipped with a tire

pressure warning valve and transmitter. If a

tire goes flat, the tire pressure warning light

will not turn off even though the flat tire has

been replaced with the spare tire.

■

Conditions that the tire pressure warn-

ing system may not function properly

P.258

■

If the tire pressure warning light fre-

quently comes on after blinking for 1

minute

If the tire pressure warning light frequently

comes on after blinking for 1 minute when

the engine switch is turned to IGNITION

ON mode, have it checked by your Lexus

dealer.

■

Warning buzzer

In some cases, the buzzer may not be heard

due to being in a noisy location or audio

sound.

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

The steering wheel may 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. Adjust the tire infla-

tion 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.)

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 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.
