ises

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

Turn the engine switch to ACC or
OFF.

Restart the engine.

Fuel pump shut off system

To minimize the risk of fuel leakage
when the engine stalls or when an
airbag inflates upon collision, the
fuel pump shut off system stops the
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-

aged and is in need of repair. Do not

restart the engine.

If the malfunction indicator lamp comes

on while driving

First check the following:

●

Is the fuel tank empty?

If it is, fill the fuel tank immediately.

●

Is the fuel tank cap loose?

If it is, tighten it securely.

The light will go off after several driving

trips.
If the light does not go off even after several

trips, contact your Lexus dealer as soon as

possible.

■

Electric power steering system warning

light (warning buzzer)

When the battery charge becomes insuffi-

cient or the voltage temporarily drops, the

electric power steering system warning

light may come on and the warning buzzer

may sound.

■

When the tire pressure warning light

comes on

Inspect the tires to check if a tire is punc-

tured.
If a tire is punctured:



P.511

If none of the tires are punctured:
Turn the engine switch to OFF then turn it

to ON. 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 pres-
sure 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.469)

■

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 a spare tire

The spare tire is also equipped with the tire

pressure warning valve and transmitter. The

tire pressure warning light will turn on if the

tire inflation pressure of the spare tire is low.

If a tire goes flat, even though the flat tire is

replaced with the spare tire, the tire pres-

sure warning light does not turn off.

Replace the spare tire with the repaired tire

and adjust the proper tire inflation pressure.

The tire pressure warning light will turn off

after a few minutes.

ing system may not function properly

WARNING

■

If a warning light comes on or a warn-

ing buzzer sounds when a warning

message is shown on the multi-infor-

mation display

Check and follow the message shown on

the multi-information display.
Failure to do so may result in death or

serious injury.

■

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.

WARNING

■

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. 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.)

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).

506

7-2. Steps to take in an emergency

WARNING

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 manufacturers, as the tire

pressure warning system may not oper-

ate properly.

If a warning message is dis-
played

The multi-information display
shows warnings of system malfunc-
tions, incorrectly performed opera-
tions, and messages that indicate a
need for maintenance. When a
message is shown, perform the cor-
rection procedure appropriate to
the message.

If a warning message is displayed
again after the appropriate actions
have been performed, contact your
Lexus dealer.
