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 (t rac-
tion battery) becomes low, the vehicle is automatically controlled
in such a way that it can be driven as a Plug-in Hybrid Electri c
Vehicle through the joint use of the gasoline engine.
*: The EV driving range will vary in accor dance with conditions such as
vehicle speed, the amount of charge remaining in the hybrid bat tery
(traction battery) and the usage of the air conditioning system . The gas-
oline engine may also be used si multaneously in accordance with driv-
ing conditions.

Plug-in hybrid system
The plug-in hybrid system oper-
ates 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.185, 196)
■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.173)
*2: Depending on the situation, EV
driving may be canceled and
both gasoline engine and electric
motor are used. ( P.80)
■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.76)
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

engine and electric motor.
(P.79)
• 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.76).
* 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.77)
Electricity generated in the gas-
oline engine can be charged in
the hybrid battery (traction bat-
tery) 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.78)
• 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 mod e indicator illu-
minates.
*: When in the hybrid battery (trac- tion battery) charge mode, the
hybrid battery can be charged
while driving. Ho wever, 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

■If the plug-in hybrid system
operation mode cannot be
changed
In the following si tuations, 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 displaye d 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 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 s witches 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 insufficien t, such as in a
garage or area with snow
buildup.
Control when driving in

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.80). 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 multi-informa-
tion display. ( P.173, 178)
■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.80)
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 th e multi-informa-
tion display. ( P.173, 178)
■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).

802-1. 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.81)
■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 si tuations, 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 lever in
D or S.
●The brake pedal is depressed
while driving with the shift lever in
D or S.
■EV driving range
●The EV driving range is displayed on the multi-information display.
(
 P.173, 178)
●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.80)
■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.191,
203)
■After EV mode has switched to
HV mode due to low hybrid bat-
tery (traction battery) charge
I f t h e h y b r i d b a t t e r y (traction battery)
is regenerated by driving continu-
ously down a long slope, the EV
driving range etc. will be displayed
on the multi-information display and
EV mode will be a utomatically
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.
■Gasoline engine operation in
EV mode or AUTO EV/HV mode
Even if there is a sufficient amount
of electricity remaining in the hybrid
