SRS warning light
This warning light system monitors the airbag sensor assembly, front impact sensors, side

impact sensors (rear), side impact sensors (front door), safing sensor (rear), driver’s seat

belt buckle switch, driver’s seat position sensor, front passenger’s seat belt buckle switch,

airbags, interconnecting wiring and power sources, front passenger occupant classifica-

■

Front passenger detection sensor, seat belt reminder and warning buzzer

●

If luggage is placed on the front passenger seat, the front passenger detection sensor

may cause the warning light to flash and the warning buzzer to sound even if a passen-

ger is not sitting in the seat.

●

If a cushion is placed on the seat, the sensor may not detect a passenger, and the warn-

ing light may not operate properly.

■

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.

■

If the low speed four-wheel drive indicator light or the center differential lock indicator

light blinks
Take the specified steps. (

P. 311)

If the brake system warning light or the malfunction indicator light also comes on, or the

low speed four-wheel drive indicator light or the center differential lock indicator light

continues to blink after taking the specified steps, there may be a malfunction in the

engine, the brake system or the four-wheel drive system. In this case, you may not be able

to transfer between “H4” and “L4” modes, and the center differential lock may not be

able to be locked or unlocked. Have the vehicle inspected by your Lexus dealer, immedi-

ately.

■

When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured:

P. 535

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 flashes.



If the tire pressure warning light comes on
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 pressure of each tire is at the specified level and perform initialization.

(

P. 489)

If the warning light does not turn off even after several minutes have elapsed, have the

vehicle inspected by your Lexus dealer immediately.



If the tire pressure warning light flashes for 1 minute then stay on

There may be a malfunction in the tire pressure warning system. Have the vehicle

inspected by your Lexus dealer immediately.

■

The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as natural air leaks

or tire inflation pressure changes caused by temperature. In this case, adjusting 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 pressure

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 min-

utes.

WARNING

■

If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehi-

cle will become extremely unstable during braking, and the ABS system may fail, which

could cause an accident resulting in death or serious injury.

■

If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of vehi-

cle control and result in death or serious injury.

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure

immediately.

●

If the tire pressure warning light comes on even after tire inflation pressure adjust-

ment, it is probable that you have a flat tire. Check the tires. If the tire is flat, change to

the spare tire and have the flat tire repaired by the nearest Lexus dealer.

●

Avoid abrupt maneuvering and braking. 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.

530

7-2. Steps to take in an emergency

WARNING

■

Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and

inflated to the inflation pressure recommended by the vehicle manufacturer on the

vehicle placard or tire inflation pressure label (tire and load information label). (If your

vehicle has tires of a different size than the size indicated on the vehicle placard or tire

inflation 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 moni-

toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure

telltale (tire pressure warning light) when one or more of your tires is significantly

under-inflated. Accordingly, 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 significantly under-inflated tire causes the

tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency

and tire tread life, and may affect the vehicle’s handling and stopping ability.
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 illumination of the TPMS low

tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-

function indicator to indicate when the system is not operating properly. The TPMS

(tire pressure warning system) malfunction indicator is combined with the low tire pres-

sure 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 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 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 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 specifications or makers, as the tire pressure warning

system may not operate properly.
