■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, the followings
are examples of conditions under which the engine may not stop automati-
cally:
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is being charged.
● The hybrid battery (traction battery) temperature is low or high.
● The temperature setting of the air conditioning system is high.
■ Charging the battery
● As the gasoline engine or regenerative brake charges the hybrid battery
(traction battery), the battery does not need to be charged from an
outside source. However, if the vehicle is left parked for a long time the
hybrid battery will slowly discharge. For this reason, be sure to drive \
the
vehicle at least once every several months for at least 30 minutes or 10
miles (16 km). If the hybrid battery becomes fully discharged and you are
unable to jump-start the vehicle with the 12 volt battery, contact your
Toyota dealer.
● If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
lever in “D” or “B” to avoid discharging the battery.
■ After the 12 volt battery has disch arged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact your Toyota
dealer.

Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and electronic key battery from
depleting.
● When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of
the vehicle for 10 minutes or more
● If the entry function has not been used for 9 days or more, the vehicle
cannot be unlocked by a door other than the driver’s door. To unlock the
vehicle, grip the driver’s door handle or use the wireless remote control
or the mechanical key.
The system will resume operation when...
● The vehicle is locked touching the door handle lock sensor area.
● The vehicle is locked/unlocked using the wireless remote control function 
( P. 63) or the mechanical key. ( P. 541)

■Panic mode
■ Door lock buzzer (vehicl es with entry function)
If a door or back door is not fully closed, a buzzer sounds continuously for 10
seconds if an attempt to lock the door is made. Fully close the door to stop
the buzzer, and lock the vehicle once more.
■ Electronic key battery depletion
● The standard battery life is 1 to 2 years. (The battery becomes depleted
even if the electronic key is not used.) If the smart key system or the
wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when
necessary. (  P. 460)
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliance that produce a magnetic field.
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps
When is pushed for longer than
about one second, an alarm will sound for
about 60 seconds and the vehicle lights
will flash to deter any person from trying
to break into or damage your vehicle.
To stop the alarm, push any button on the
wireless remote control.

PRIUS_U (OM47668U) U.S.A.
CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. 
Failure to do so, may result in death or serious injury.
● Touch the vehicle or some other metal surface to discharge any static
electricity. 
Sparks resulting from discharging static electricity may cause the fuel
vapors to ignite.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it. 
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
bodies to come close to an open fuel tank.
● Do not inhale vaporized fuel. 
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle. 
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged. 
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

Reverse warning buzzer
When shifting into “R”, a buzzer will sound to inform the driver that the shift
lever is in “R”.
■ When in heavy traffic
If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in “N” for an extended period of time.
■ Eco Driving Mode
When the accelerator pedal is depressed in Eco Driving Mode, it may take
more time to accelerate than usual. This is normal operation.
■ If the system malfunctions
The following situations indicate a problem with the system. 
Immediately stop the vehicle in a safe place and contact your Toyota dealer.
● The indicator on the “P” position switch flashes. However, this does not
indicate a malfunction unless a warning message appears in the multi-
information display.
● All frames of the shift position indicators in the instrument cluster flash.
● The parking system error message appears on the multi-information dis-
play.
● The instrument cluster does not come on when the “POWER” switch is in
ON mode.

Before recharging
When recharging, the 12 volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, before recharging:
● If recharging with the 12 volt battery installed on the vehicle, be sure to
disconnect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12 volt battery.
■ 12 volt battery exterior
Make sure that the 12 volt battery terminals are not corroded
and that there are no loose c onnections, cracks, or loose
clamps.

■After recharging/reconnecting the 12 volt battery
● Unlocking the doors using the smart key system may not be possible
immediately after disconnecting the 12 volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
● Start the hybrid system with the “POWER” switch in ACCESSORY mode.
The hybrid system may not start with the “POWER” switch turned OFF.
However, the hybrid system will operate normally from the second
attempt.
● The “POWER” switch mode is recorded by the vehicle. If the battery is
reconnected, the vehicle will return the “POWER” switch mode to the sta-
tus it was in before the battery was disconnected. Make sure to turn off
the power before disconnect the battery. Take extra care when connect-
ing the battery if the “POWER” switch mode prior to discharge is
unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
CAUTION
■ Chemicals in the 12 volt battery
The 12 volt battery contains poisonous and corrosive sulfuric acid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk
of death or serious injury, take the following precautions while working on or
near the 12 volt battery:
● Do not cause sparks by touching the 12 volt battery terminals with tools.
● Do not smoke or light a match near the 12 volt battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
