(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

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.
■When in EV mode
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

Plug-in hybrid system
using only the electric motor)* is
possible. However, depending
on the situation, EV driving may
be canceled and both gasoline
engine and electric motor are
used ( P.79). Also, if a little
electricity is remaining in the
hybrid battery (traction battery),
HV mode is automatically
selected. To drive in EV mode
long, observe the followings.
 Avoid sudden acceleration
and sudden deceleration, and
be sure to drive smoothly. If
you repeatedly accelerate,
the hybrid battery (traction
battery) charge will deplete
quickly. Also, EV driving may
be canceled by rapid acceler-
ation or vehicle speed.
 Restrain your speed as much
as possible. The distance that
can be driven in EV mode will
reduce considerably at high
speeds.
*: The EV driving range can be
checked using the meter.
( P.155)
■When in AUTO EV/HV mode
Only the electric motor is used
for EV driving
* during normal
driving, but when the accelera-
tor pedal is strongly depressed,
the gasoline engine starts.
( P.79)
Also, when the hybrid battery
(traction battery) level is low, the
mode switches to HV mode automatically the same as in EV
mode.
AUTO EV/HV mode is suitable
for driving conditions when more
power is required, such as for
driving uphill or accelerating
suddenly. However, because
the gasoline engine will start
more easily, it is recommended
to drive in EV mode usually.
*: The EV driving range can be
checked using the meter.
( P.155)
■When in HV mode
The vehicle can be used in the
same way as a standard Plug-in
Hybrid Electric Vehicle
In HV mode, controls are pri-
marily carried out as follows in
accordance with the driving con-
ditions.
 The gasoline engine stops
*
when the vehicle is stopped.
 During start off, the electric
motor (traction motor) drives
the vehicle.
 During normal driving, the
gasoline engine and electric
motor (traction motor) are
controlled effectively, and the
vehicle is driven with optimum
fuel efficiency. Also, when
necessary, the electric motor
(traction motor) operates as
an electrical generator to
charge the hybrid battery
(traction battery).

782-1. Plug-in hybrid system
When the accelerator pedal is
depressed heavily, drive force
from both the gasoline engine
and the electric motor (trac-
tion motor) is used to acceler-
ate.
*: When the hybrid battery (traction
battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P.79)
■When braking (regenera-
tive braking)
The electric motor (traction
motor) charges the hybrid bat-
tery (traction battery).
The EV driving range can be
extended by actively using this
regenerative braking to store
electricity in the hybrid battery
(traction battery).
Moreover, as fuel consumption
is also reduced when in HV
mode, the regenerative braking
system can be used effectively.
■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 bat-
tery (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.
●The Regeneration Boost oper-
ates when the shift position is
shifted to B. The regenerative
braking force can be changed when the Regeneration Boost is
operating. (
P.260)
■EV driving range
●The EV driving range is displayed
on the meter. ( P.155)
●The EV driving range changes in
accordance with the charge status
of the hybrid battery (traction bat-
tery), the speed of the vehicle, etc.
●Even if there is enough charge
remaining in the hybrid battery
(traction battery), EV driving may
be canceled and both gasoline
engine and electric motor are
used depending on the situation.
( P.79)
■EV indicator
The EV indicator comes on when
the vehicle is driven using only the
electric motor (traction motor) or the
gasoline engine is stopped.
The on/off operation of the EV indi-
cator can be changed. ( P.166)
■After EV mode has switched to
HV mode due to low hybrid bat-
tery (traction battery) charge
If the hybrid battery (traction battery)
is regenerated by driving continu-
ously down a long slope, the EV
driving range etc. will be displayed
on the meter an d EV mode will be
automatically switched to.
If EV mode is not switched to even
though EV driving range is being
displayed, EV mode can be
switched to by pressing the EV/HV
mode selection switch.

schedules, the closest charging
schedule after the current time is called the “Next Event”.
For charging schedule, AC
charging will be performed
according to the “Next Event”.
The charging schedule can be
registered on the multi-informa-
tion display or Multimedia Dis-
play.
