Prius Plug-in Hybrid_OM_OM47E75E_(EE)The vehicle is equipped with sophisticated computers that will record certain
data, such as:
• Engine speed/Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras
Your vehicle is equipped with cameras. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer for the loca-
tion of recording cameras.
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level, options and
destinations with which it is equipped.
These computers do not record conversations or sounds, and only record
images outside of the vehicle in certain situations.
OData usage
Toyota may use the data recorded in this computer 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
ORecorded image information can be erased by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
The image recording function can be disabled. However, if the function is
disabled, data from when the system operates will not be available.
The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer, before
you scrap your vehicle.

Prius Plug-in Hybrid_OM_OM47E75E_(EE)
For safety and security
QIf the SRS airbags deploy (inflate)
O Slight abrasions, burns, bruising etc., may be sustained from SRS airbags,
due to the extremely high speed depl oyment (inflation) by hot gases.
O A loud noise and white powder will be emitted.
O Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front and rear pillars, a nd roof side rails,
may be hot for several minutes. The airbag itself may also be h ot.
O The windshield may crack.
O The hybrid system will be stopped and fuel supply to the engine will be
stopped. ( P. 99)
O The emergency flashers will turn on automatically. (P. 646)
Q SRS airbag deployment conditions (SRS front airbags)
O The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an app roximately 20 -
30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or
deform).
However, this threshold veloci ty will be considerably higher in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
O Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
Q SRS airbag deployment conditions (SRS side and curtain shield airbags)
O The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 1500 kg [3300 lb.] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 20 - 30 km/h [12 - 18 mp h]).
O Both SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.

Plug-in hybrid system features
The illustration is an example for explanation and may differ from the
actual item.
Gasoline engine
Electric motor (traction motor)
The plug-in hybrid system is a system excellent in both econom-
ical efficiency of electric vehicles and practicality of hybrid vehi-
cles.
O EV driving can be performed using electricity charged from an
external power source.*
O If the amount of electricity remaining in the hybrid battery (traction
battery) becomes low, the vehicle is automatically controlled i n
such a way that it can be driven as a hybrid vehicle through th e
joint use of the gasoline engine.
*: The EV driving range will vary in accordance with conditions s uch as
vehicle speed, the amount of charge remaining in the hybrid bat tery
(traction battery) and the usage of the air conditioning system . The gaso-
line engine may also be used simultaneously in accordance with driving
conditions.

Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
The plug-in hybrid system operates in the following modes.
The multi-information display can be used to check which mode the plug-in
hybrid system is currently being driven in. (P. 220)
EV mode
When a sufficient amount of electricity is remaining after
charging
*1, EV driving is performed using electricity stored in the
hybrid battery (traction battery).
*2
When in EV mode, the EV drive mode indicator illuminates.
*1: The amount of remaining charge can be checked on the multi-informa-
tion display etc. (P. 232)
*2: Depending on the situation, EV driving may be canceled and both gaso-
line engine and electric motor are used. (P. 94)
Plug-in hybrid system operation mode

862-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
EV City mode (P. 8 8 )
When a sufficient amount of electricity for EV driving is remaining in
the hybrid battery (traction battery)
*1, the operation mode can be
switched to EV City mode.
EV City mode limits motor output and minimizes the operation of
the gasoline engine.
*2 Therefore, the vehicle can be driven with
only electric motor (traction motor) in city areas, etc.
When in EV City mode, the EV City mode indicator illuminates.
*1: The amount of remaining charge can be checked on the multi-informa-
tion display etc. (P. 232)
*2: When acceleration is required, fully depress the accelerator pedal to
start the gasoline engine.
HV mode
When in HV mode, the vehicle is driven using both the gasoline
engine and electric motor (traction motor). (P. 9 2 )
OIf electricity needed for EV driving in EV mode is not remaining,
the operation mode will be automatically switched to HV mode.
OThe operation mode can be switched to HV mode at any timing
by operating the switch to keep electricity for EV driving etc.
*
(P. 88). Switching to HV mode when driving on a highway or
when driving uphill is recommended in order to conserve battery
power.
When in HV mode, the EV drive mode indicator and EV City mode indi-
cator turn off.
*: The EV driving range may reduce even after switching to HV mode.

Hybrid battery (traction battery) charge mode (P. 8 9 )
Electricity generated in the gasoline engine can be charged in the
hybrid battery (traction battery) by switching to the hybrid battery
(traction battery) charge mode when electricity needed for EV driv-
ing is not remaining.*
OThe system may not be able to switch to the hybrid battery (trac-
tion battery) charge mode due to the state of the plug-in hybrid
system. (P. 9 0 )
OCharging time differs depending on the driving state of the vehi-
cle when driving in hybrid battery (traction battery) charge mode.
When in the hybrid battery (traction battery) charge mode, the hybrid
battery charge mode indicator illuminates.
*: When in the hybrid battery (traction battery) charge mode, the hybrid
battery can be charged while driving. However, the gasoline engine runs
to charge the battery and fuel consumption becomes higher compared
with driving in HV mode.
