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.
● EV driving can be performed using electricity charged from an
external power source.*
● If the amount of electricity remaining in the hybrid battery (traction
battery) becomes low, the vehicle is automatically controlled in
such a way that it can be driven as a hybrid vehicle through the
joint use of the gasoline engine.
*: The EV driving range will vary in accordance with conditions such as
vehicle speed, the amount of charge remaining in the hybrid battery
(traction battery) and the usage of the air conditioning system. The gaso-
line engine may also be used simultaneously in accordance with driving
conditions.

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. 230)
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. 242)
*2: Depending on the situation, EV driving may be canceled and both gaso-
line engine and electric motor are used. (P. 104)

962-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
EV City mode (P. 9 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. 242)
*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. 102)
●If electricity needed for EV driving in EV mode is not remaining,
the operation mode will be automatically switched to HV mode.
●The operation mode can be switched to HV mode at any timing
by operating the switch to keep electricity for EV driving etc.
*
(P. 98). 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. 9 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.*
●The 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. 100)
●Charging 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.

●The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or cannot
cancel it
• Gasoline engine does not start or stops even after switching to hybrid bat-
tery (traction battery) charge mode
●If a load to the system is large, such as when the power consumption of the
air conditioning system is large or when the temperature of the engine cool-
ant is high, it may take longer time than usual to charge using the hybrid bat-
tery (traction battery) charge mode, or charging to the hybrid battery
(traction battery) may not be performed.
