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.

NOTICE

: Driver's and front passenger's seat belt warning buzzer:

The driver’s seat belt warning buzzer sounds to alert the driver that his or her seat belt

is not fastened. Once the engine switch is turned to IGNITION ON mode, the

buzzer sounds for 6 seconds. If the vehicle reaches a speed of 12 mph (20 km/h), the

■

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.

■

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

P. 666

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 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. 606)

If the warning light does not turn off several minutes after the initialization has been per-

formed, have the vehicle inspected by your Lexus dealer immediately.



If the tire pressure warning light blinks for 1 minute then stays 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 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, 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 compact spare tire is not equipped with a tire pressure warning valve and transmit-

ter. 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. Replace the spare tire with the repaired tire

and adjust the tire inflation pressure. The tire pressure warning light will go off after a few

minutes.

■

Conditions that the tire pressure warning system may not function properly
P. 609

■

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 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.

■

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 precautions. 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 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 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 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.

8-2. Steps to take in an emergency

RX350/RX350L_U

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.
