For safety and security
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint.
● Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat
tracks and stop the seat from locking in place. This may lead to an acci-
dent and the adjustment mechanism may also be damaged.
● Always observe the legal speed limit when driving on public roads.
● When driving over long distances, take regular breaks before you start to
feel tired.
Also, if you feel tired or sleepy while driving, do not force yourself to con-
tinue driving and take a break immediately.

821-2. Hybrid system
PRIUS +_OM_OM47D30E_(EE)
◆When stopped/during start off
The gasoline engine stops* when the vehicle is stopped. During
start off, the electric motor (traction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine is
stopped* and the electric motor (traction motor) is used.
When shift position is in N, the hybrid battery (traction battery) is not
being charged.
*: When the hybrid battery (traction battery) requires charging or the engine
is warming up, etc., the gasoline engine will not automatically stop.
( P. 83)
◆During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery (traction battery) as nec-
essary.
◆When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the
hybrid battery (traction battery) is added to that of the gasoline
engine via the electric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power
generator, and the hybrid battery (traction battery) is charged.
■ Regenerative braking
In the following situations, kinetic ener gy is converted to electric energy and
deceleration force can be obtained in c onjunction with the recharging of the
hybrid battery (traction battery).
● The accelerator pedal is released while driving with the shift position in D or
B.
● The brake pedal is depressed while driving with the shift position in D or B.

For safety and security
■Hybrid System Indicator
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the heater is switched on
■ Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery (traction battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 16 km (10 miles). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■ Charging the 12-volt battery
 P. 516
■ After the 12-volt battery has discharged or when the terminal has been
removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
Hybrid System Indicator represents the
hybrid system power output and regener-
ative charging. ( P. 124)

■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent under the right-
hand front seat.
■ Maintenance, repair, recycling, and disposal
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer regarding maintenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.

861-2. Hybrid system
PRIUS +_OM_OM47D30E_(EE)
There is an air intake vent under
the right-hand front seat for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vent
becomes blocked, the hybrid bat-
tery (traction battery) may over-
heat, leading to a reduction in
hybrid battery (traction battery)
output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. ( P. 458)
