2-1. Plug-in hybrid system
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.166)
QEV mode
When a sufficient amount of elec-
tricity is remaining after charging*1,
EV driving is performed using elec-
tricity 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 SOC (State of
Charge) gauge. ( P.172)
*2: Depending on the situation, EV driv-
ing may be canceled and both gaso-
line engine and electric motor are
used. ( P.90)
QAUTO 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 accel-
eration by strongly depressing the
accelerator pedal.
When the vehicle is in a condition
where EV driving is possible, EV
mode and AUTO EV/HV mode can
be switched by operating the
switch. ( P.86)
When in AUTO EV/HV mode, the
AUTO EV/HV mode indicator illumi-
nates.
QHV mode
When in HV mode, the vehicle is
driven using both the gasoline
Plug-in hybrid system oper-
ation mode

charge will deplete quickly. Also,
EV driving may be canceled by
rapid acceleration 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-information display.
(P.179)
QWhen in AUTO EV/HV mode
Only the electric motor is used for
EV driving
* during normal driving,
but when the accelerator pedal is
strongly depressed, the gasoline
engine starts. (P.90)
Also, when the hybrid battery (trac-
tion 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 driv-
ing 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 multi-information display.
(P.179)
QWhen 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 primarily carried out as follows in accor-
dance with the driving conditions.
The gasoline engine stops
* when
the vehicle is stopped.
During start off, the electric
motor (traction motor) drives the
vehicle.
During normal driving, the gaso-
line engine and electric motor
(traction motor) are controlled
effectively, and the vehicle is
driven with optimum fuel effi-
ciency. Also, when necessary,
the electric motor (traction
motor) operates as an electrical
generator to charge the hybrid
battery (traction battery).
When the accelerator pedal is
depressed heavily, drive force
from both the gasoline engine
and the electric motor (traction
motor) is used to accelerate.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine
is warming up, etc., the gasoline
engine will not automatically stop.
(P.91)
QWhen braking (regenerative
braking)
The electric motor (traction motor)
charges the hybrid battery (traction
battery).
The EV driving range can be
extended by actively using this
regenerative braking to store elec-
tricity in the hybrid battery (traction
battery).

922-1. Plug-in hybrid system
hybrid battery (traction battery)
from an external power source
before using the vehicle.
Even if charging the hybrid battery
(traction battery) has not been com-
pleted, the vehicle can be driven. How-
ever, if there is not enough charge
remaining, it is possible that the vehicle
cannot be driven in EV mode or AUTO
EV/HV mode, or the EV driving range
will become shorter.
QRefilling fuel
Plug in Hybrid Electric Vehicles can be
driven using electricity charged from an external power source. However, as the gasoline engine is used depending on
the situation ( P.90) even if in EV mode or AUTO EV/HV 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 immedi-
ately when the fuel level becomes low. ( P.298)
QIf the vehicle is not used for a long time
OThe 12-volt battery may discharge. In
this event, charge the 12-volt battery. ( P.546) In order to prevent the hybrid battery
(traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from external power source or start the
hybrid system at least once every 2 or 3 months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after approximately 10 seconds have
passed since the “READY” indicator came on, the power switch can be turned to off without any further
action.) When the 12-volt battery is dis-charged, refer to “If the 12-volt battery
is discharged” ( P.546) and perform the correction procedure.
OWhen the vehicle is left with the AC charging cable connected, the elec-tricity consumption amount of the 12-
volt battery increases due to controls, such as the system checking, operat-ing. When the AC charging cable is
not needed, remove it from the vehi- cle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of the
vehicle’s approach. The sound will
stop when the vehicle speed
exceeds approximately 25 km/h (15
mph).
QAcoustic Vehicle Alerting System
In the following cases, the Acoustic
Vehicle Alerting System may be difficult for surrounding people to hear.
OIn very noisy areas
OIn the wind or the rain
Acoustic Vehicle Alerting
System

1002-1. Plug-in hybrid system
Shift the shift lever to D when
stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift
lever to P when parking. When
using the N, there is no positive
effect on fuel consumption. In the
N, the gasoline engine operates but
electricity cannot be generated.
Also, when using the air condition-
ing system, etc., the hybrid battery
(traction battery) power is con-
sumed.
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accelera-
tion and deceleration will make
more effective use of the electric
motor (traction motor) without
having to use gasoline engine
power.
Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (traction
battery) power, resulting in poor
fuel consumption. Battery power
can be restored by driving with
the accelerator pedal slightly
released.
Make sure to operate the brakes
gently and a timely manner. A greater amount of electrical energy
can be regenerated when slowing
down.
Repeated acceleration and decel-
eration, as well as long waits at traf-
fic lights, will lead to high fuel and
electricity consumption. Check traf-
fic reports before leaving and avoid
delays as much as possible. When
driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly
while avoiding overuse of the accel-
erator pedal. Doing so can help
control excessive electricity and
fuel consumption.
Control and maintain the vehicle
at a constant speed. Before stop-
ping at a toll booth or similar,
allow plenty of time to release
the accelerator and gently apply
the brakes. A greater amount of
electrical energy can be regener-
ated when slowing down.
Electricity consumption will
increase significantly when driv-
ing at high speeds in EV mode or
AUTO EV/HV mode. If there will
be a long distance to the next
external charging point after
leaving a freeway, it is recom-
mended to drive in HV mode
while on the freeway and change

mode after leaving the freeway.
(P.86)
Turn the “A/C” switch off when it
is not needed. Doing so can help
reduce excessive electricity and
fuel consumption.
In summer: When the ambient tem-
perature is high, use the recirculated air
mode. Doing so will help to reduce the
burden on the air conditioning system
and reduce electricity and fuel con-
sumption as well.
In winter: Avoid excessive and unnec-
essary use of the heater. Usage of the
heated steering wheel (if equipped)
(P.416) and seat heaters (P.417)
are effective.
Using the Remote Air Condition-
ing System (P.414) while the
AC charging cable is connected
to the vehicle can reduce elec-
tricity consumption immediately
after starting off by operating air
conditioning mainly using elec-
tricity from an external power
source.
When setting the charging
schedule, setting the charging
mode to “Departure” and “Cli-
mate Prep” to on can reduce
electricity consumption immedi-
ately after starting off by operat-
ing air conditioning before
charging is completed. (P.143)Make sure to check the tire inflation
pressure frequently. If there is
improper tire inflation pressure in
the tires, the EV driving range will
become shorter, and fuel consump-
tion when in HV mode will increase.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to increased fuel
and electricity consumption.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a
large roof rack will also cause poor
fuel economy.
Since the gasoline engine starts up
and cuts out automatically, warm-
ing up is not necessary.
