2-1.Plug-in hybrid system
The illustration is an example for explanation and may differ from the actual
item.
Gasoline engine
Electric motor (traction motor)
Plug-in hybrid system features
The plug-in hybrid system is a system excellent in both eco-
nomical efficiency of electric vehicles and practicality of Plug-
in Hybrid Electric Vehicles
 EV driving can be performed using electricity charged from an
external power source.
*
If the amount of electricity remaining in the hybrid battery (trac-
tion battery) becomes low, the ve hicle is automatically controlled
in such a way that it can be driven as a Plug-in Hybrid Electric
Vehicle through the joint use of the gasoline engine.
*: The EV driving range will vary in a ccordance 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 gas-
oline engine may also be used simultaneously in accordance with driv-
ing conditions.

Plug-in hybrid system
The plug-in hybrid system oper-
ates in the following modes.
The meter display can be used to
check which mode the plug-in
hybrid system is currently being
driven in. (P.150)
■EV mode
When a sufficient amount of
electricity is remaining after
charging
*1, EV driving is per-
formed using electricity stored in
the hybrid battery (traction bat-
tery).
*2
When in EV mode, the EV drive
mode indicator illuminates.
*1: The amount of remaining charge can be checked on the SOC
(State of Charge) gauge.
( P.155)
*2: Depending on the situation, EV
driving may be canceled and
both gasoline engine and electric
motor are used. ( P.79)
■AUTO EV/HV mode
Normally, the electricity stored
in the hybrid battery (traction
battery) is used for EV driving.
However, when more power is
required, such as for driving
uphill or accelerating suddenly,
the gasoline engine starts and
provides powerful acceleration
by strongly depressing the
accelerator pedal.
When the vehicle is in a condi-
tion where EV driving is possi-
ble, EV mode and AUTO EV/HV
mode can be switched by oper-
ating the switch. ( P.74)
When in AUTO EV/HV mode, the
AUTO EV/HV mode indicator illumi-
nates.
■HV mode
When in HV mode, the vehicle is
driven using both the gasoline
Plug-in hybrid system

742-1. Plug-in hybrid system
engine and electric motor.
(P.77)
• If electricity needed for EV driving in EV mode or AUTO
EV/HV 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 driv-
ing etc. ( P.74).
* 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 HV drive
mode indicator illuminates.
*: The EV driving range may reduce even after switching to HV mode.
■Hybrid battery (traction bat-
tery) charge mode ( P.75)
Electricity generated by the gas-
oline engine can be used to
charge the hybrid battery (trac-
tion battery) by switching to the
hybrid battery (traction battery)
charge mode when electricity
needed for EV driving is not remaining.
*
• The system may not be able
to switch to the hybrid battery
(traction battery) charge
mode due to the state of the
plug-in hybrid system.
( P.76)
• Charging time differs depend- ing on the driving state of the
vehicle when driving in hybrid
battery (traction battery)
charge mode.
When in the hybrid battery (traction
battery) charge mode, the hybrid
battery charge mode indicator illu-
minates.
*: When in the hybrid battery (trac-tion battery) charge mode, the
hybrid battery can be charged
while driving. However, the gaso-
line engine runs to charge the
battery and fuel consumption
becomes higher compared with
driving in HV mode.
The plug-in hybrid system oper-
ation modes can be switched
using the switches.
■Switching the plug-in
hybrid system operation
modes
Press the AUTO EV/HV mode
switch or EV/HV mode selection
switch to change modes as the
following table shows.
When in EV mode, the EV drive

AUTO EV/HV mode switch
*: If there is not enough charge remaining in the hybrid battery
(traction battery) to allow EV driv-
ing, AUTO EV/HV mode will not
be selectable.
EV/HV mode selection switch
*: If there is not enough charge remaining in the hybrid battery
(traction battery) to allow EV driv-
ing, EV mode will not be select-
able.
■Switching to the hybrid bat-
tery (traction battery)
charge mode
Press and hold the EV/HV mode
selection switch.
Take your hand off the switch once
the hybrid battery charge mode
indicator starts to blink.
The hybrid battery charge mode
indicator illuminates when the
switch to hybrid battery (traction
battery) charge mode is complete.
When the hybrid battery (traction
battery) is sufficient charged
*, the
hybrid battery (traction battery)
charge mode is automatically can-
celed and the operation mode will
be switched to HV mode.
The hybrid battery (traction bat-
tery) charge mode will be canceled
by pressing AUTO EV/HV mode
switch or EV/HV mode selection
switch.
*: The maximum charge amount in the hybrid battery (traction bat-
tery) charge mode is approxi-
mately 80% of the sufficient
charged capacity for the charging

from an external power source.
■If the plug-in hybrid system
operation mode cannot be
changed
In the following situations, the plug-
in hybrid system operation mode
cannot be changed even if the
AUTO EV/HV mode switch or
EV/HV mode selection switch is
pressed. (In this case, the warning
message is displayed on the multi-
information displa y when the switch
is pressed.)
●When electricity needed for EV
driving is not remaining (when in
EV mode or AUTO EV/HV mode)
●When the hybrid battery (traction
battery) is almost completely
charged (hybrid battery [traction
battery] charge mode)
■When switching from EV mode
to another mode using the
switch
When the power switch is turned off,
operation mode switching is can-
celed and the system returns to EV
mode the next time the vehicle is
started.
*
*
: If there is not enough charge remaining in the hybrid battery
(traction battery) to allow EV driv-
ing, the system switches to HV
mode.
■Hybrid battery (traction battery)
charge 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 battery (traction battery)
charge mode
●If a load to the system is large,
such as when the power con-
sumption of the air conditioning
system is large or when the tem-
perature of the engine coolant is
high, it may take longer time than
usual to charge using the hybrid
battery (traction battery) charge
mode, or charging to the hybrid
battery (traction battery) may not
be performed.

WARNING
■When using the hybrid bat-
tery (traction battery) charge
mode
Observe the following precautions
when using the hybrid battery
(traction battery) charge mode
while parking.
Failure to do so may lead to death
or serious health hazard, as the
gasoline engine operates when in
the hybrid battery (traction bat-
tery) charge mode.
●Do not stop the vehicle near
flammable materials.
●Do not use the hybrid battery
(traction battery) charge mode
in a closed area where ventila-
tion is insufficient, such as in a
garage or area with snow
buildup.
Control when driving in
each mode
