Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Vehicles without a smart entry & start system
Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
Vehicles with a smart entry & start system
Turn the engine switch to ACCESSORY mode or turn it off.
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 the 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.

*1: Parking brake engaged warning buzzer:
A buzzer will sound if the vehicle is driven at a speed of approximately
5 km/h (3 mph) or more.
*2: Open door warning buzzer:
A buzzer will sound if the vehicle reaches a speed of 5 km/h (3 mph) or
more with any door open.
*3: Driver’s and front passenger’s seat belt warning buzzer:
The driver’s and front passenger’s seat belt warning buzzer sounds to alert
the driver and front passenger that his or her seat belt is not fastened. If
the seat belt is unfastened, the buzzer sounds intermittently for a certain
period of time after the vehicle reaches a certain speed.
*4: Rear passengers’ seat belt warning buzzer:
The rear passengers’ seat belt warning buzzer sounds to alert the rear
passenger that his or her seat belt is not fastened. If the seat belt is unfas-
tened, the buzzer sounds intermittently for a certain period of time, after
the seat belt is fastened and unfastened and the vehicle reaches a certain
speed.
Low fuel level warning light (warning buzzer)
Indicates remaining fuel is approximately 5.25 L (1.4 gal.,
1.1 Imp.gal.) or less
Refuel the vehicle.
Tire pressure warning light (if equipped)
When the light comes on:
Low tire inflation pressure such as
• Natural causes ( P. 455)
• Flat tire ( P. 459, 481)
Adjust the tire inflation pressure to the specified level.
The light will turn off after a few minutes. In case the
light does not turn off even if the tire inflation pressure
is adjusted, have the system checked by any autho-
rized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
When the light comes on after blinking for 1 minute:
Malfunction in the tire pressure warning system ( P. 456)
Have the system checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable
repairer.

When trouble arises
AYGO_OM_Europe_OM9A012E
■To prevent the clutch from overheating (vehicles with a multi-mode man-
ual transmission)
● Do not use the accelerator pedal or starting assist system to hold the vehicle
on a hill.
● On an uphill incline, observe the following whenever possible:
• Maintain a safe distance from the vehicle ahead and avoid unnecessary
starting off and stopping.
• Avoid using E mode on an uphill slope. This will help to avoid unneces-
sary gear changes.
■ 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
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empt y, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer as soon
as possible.
■ Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient 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 (vehicles with the tire
pressure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 459, 481
If the tire is not punctured:
Check the tire inflation pressure after the tire temperature has lowered suffi-
ciently. Adjust the inflation pressure to the appropriate level and carry out ini-
tialization. ( P. 4 0 6 )
■ The tire pressure warning light may come on due to natural causes
(vehicles with the tire pressure warning system)
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 is at the specified level and
carry out initialization. ( P. 406)
