PRIUS_OM_OM47B89U_(U)Your Toyota is equipped with several sophisticated computers that will record
certain data, such as:
• Engine speed
• Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level and options
with which it is equipped. These computers do not record conversations or
sounds, and only record images outside of the vehicle in certain situati\
ons.
●Data Transmission
Your vehicle may transmit the data re corded in these computers to Toyota
without notification to you.
●Data usage
Toyota may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a govern- ment agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
●Usage of data collected through Safety Connect (U.S. mainland only)
If your Toyota has Safety Connect and if you have subscribed to those ser-
vices, please refer to the Safety Connect Telematics Subscription Service
Agreement for information on data collected and its usage.

781-3. Hybrid system
PRIUS_OM_OM47B89U_(U)
Hybrid system features
The illustration is an example for explanation and may differ from the
actual item.
Gasoline engine
Electric motor (traction motor)
Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar with
the characteristics of your vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction moto r) according to driving condi-
tions, improving fuel efficien cy and reducing exhaust emis-
sions.

For safety and security
◆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. 80)
◆During normal driving
The gasoline engine is predomin antly 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.
When driving with the gasoline engine stopped, a sound, which
changes in accordance with the driving speed, will be played in order
to warn people nearby of the vehi cle’s approach. The sound will stop
when the vehicle speed exceeds approximately 15 mph (25 km/h).

PRIUS_OM_OM47B89U_(U)
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction 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.
■ 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
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
■ 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 10 miles (16 km). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact your Toyota dealer.
■ Charging the 12-volt battery
→P. 731
■ After the 12-volt battery has dischar ged 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 your
Toyota dealer. Hybrid System Indicator represents the
hybrid system power output and regener-
ative charging. ( →P. 119)

For safety and security
■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. ( →P. 83)
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
● In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
