Plug-in hybrid system
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. 231)
*2: Depending on the situation, EV driving may be canceled and both gaso-
line engine and electric motor are used. (P. 95)

EV auto mode (P. 9 0 )
When a sufficient amount of electricity for EV driving is remaining in
the hybrid battery (traction battery) after charging
*, the operation
mode can be switched to EV auto mode.
Switching to EV auto mode make powerful driving possible by using
both the gasoline engine and electric motor in a driving condition
that requires large driving force, such as when passing a vehicle on
a highway or driving on a steep slope.
When in EV auto mode, the EV auto mode indicator illuminates.
*: The amount of remaining charge can be checked on the multi-informa-
tion display etc. (P. 231)
HV mode
When in HV mode, the vehicle is driven using both the gasoline
engine and electric motor (traction motor). (P. 9 2 )
●If electricity needed for EV driving in EV mode or EV auto 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. 90). 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 auto mode indi-
cator turn off.
*: The EV driving range may reduce even after switching to HV mode.

■Switching to the hybrid battery (traction battery) charge mode
Press and hold the 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 com-
plete.
When the hybrid battery (traction battery) is fully charged
*, the hybrid
battery (traction battery) charge mode is automatically canceled and the
operation mode will be switched to HV mode.
The hybrid battery (traction battery) charge mode will be canceled by
pressing EV/HV mode selection switch or EV auto mode switch.
*: The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully 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 EV/HV mode selection switch or EV auto mode switch
is pressed. (In this case, the warning message is displayed on the multi-infor-
mation display when the switch is pressed.)
●When electricity needed for EV driving is not remaining (when in EV/EV
auto mode)
●When the traction battery is almost completely charged (hybrid battery [trac-
tion 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 canceled
and the system returns to EV mode the next time the vehicle is started.
■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 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.

■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.
■EV driving range
●The EV driving range is displayed on the multi-information display etc.
(P. 214, 230, 237, 254)
●The EV driving range changes in accordance with the charge status of the
hybrid battery (traction battery), the speed of the vehicle, etc.
●Even if there is enough charge remaining in the hybrid battery (traction bat-
tery), EV driving may be canceled and both gasoline engine and electric
motor are used depending on the situation. (P. 95)
■After EV mode has switched to HV mode due to low hybrid battery (trac-
tion battery) charge
If the hybrid battery (traction battery) is regenerated by driving continuously
down a long slope, the EV driving range etc. will be displayed on the multi-
<004c0051004900520055005000440057004c0052005100030047004c00560053004f0044005c0003004400510047000300280039000300500052004700480003005a004c004f004f00030045004800030044005800570052005000440057004c0046004400
4f004f005c00030056005a004c00570046004b004800470003[to.
If EV mode is not switched to even though EV driving range is being dis-
played, EV mode can be switched to by pressing the EV/HV mode selection
switch.
■Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source. However, as the gasoline engine is used depending on the
situation even if in EV mode, and the gasoline engine is provided on board as
a power source for driving in HV mode, it is needed to refueling the vehicle.
Check the fuel amount and refill immediately when the fuel level becomes
low. (P. 371)
