Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Vehicles with smart key system: Turn the “ENGINE START
STOP” switch OFF.
Vehicles without smart key system: Turn the engine switch to
the “ACC” or “LOCK” position.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.

■If the malfunction indicator lamp comes on while driving
First check the following:
●Is your vehicle low on gas?
If it is, refuel the vehicle immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after taking several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■SRS warning light
This warning light system monitors the following:
●The airbag sensor assembly
●Front airbag sensors
●The curtain shield airbag sensors
●The side and curtain shield airbag sensor assemblies
●The driver’s seat position sensor
●Driver’s seat belt buckle switch
●The front passenger occupant classification ECU
●The pressure sensor
●The belt tension sensor
●“AIR BAG ON” and “AIR BAG OFF” indicator lights
●Front passenger’s seat belt buckle switch
●The inflators
●The warning light
●The interconnecting wiring and power sources
■Front passenger detection sensor and passenger seat belt reminder
If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor may cause the warning light to flash, even if a passenger is not
sitting in the seat.

CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause 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 pres-
sure adjustment, 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 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 differ-
ent 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.
