Fuel pump shut off system

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

Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.

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 supply of fuel to 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
damaged and is in need of repair. Do not restart the engine.

■

SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors (front door), side impact sensors (rear), driver’s
seat position sensor, driver’s seat belt buckle switch, front passenger occu-
pant classification system (ECU and sensors), “AIR BAG ON” indicator light,

■

Front passenger detection sensor, seat belt reminder and warning
buzzer

●

If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.

●

If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning 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 Toyota dealer
as soon as possible.

■

When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Push-

ing the tire pressure warning reset switch will not turn off the tire pressure

warning light.

552

■

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 tem-

perature. In this case, adjusting the tire inflation pressure will turn off the

warning light (after several minutes).

■

When a tire is replaced with a spare tire
The temporary 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 temporary

spare tire. Replace the temporary spare tire with the repaired tire and

adjust the tire inflation pressure. The tire pressure warning light will go off

after several minutes.

■

Conditions that the tire pressure warning system may not function

properly
P. 501

■

If the tire pressure warning light frequently 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 “ON” position, have it checked

by your Toyota dealer.

■

Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.

553

WARNING

■

If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
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.

■

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 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 Toyota 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.

■

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 dif-

ferent 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 monitoring 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) illumi-

nates, 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.

554

WARNING

Please note that the TPMS (tire pressure warning system) is not a sub-

stitute 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 warn-

ing system) malfunction indicator to indicate when the system is not

operating properly. The TPMS (tire pressure warning system) malfunc-

tion indicator is combined 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 malfunction indicator is illu-

minated, the system may not be able to detect or signal low tire pres-

sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-

ety 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 pres-

sure 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

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.
