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

*: 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

■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.

In EV mode, EV driving (driving 
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
