WARNING
QGeneral precautions while driv- ing
Driving under the influence: Never
drive your vehicle when under the influence of alcohol or drugs that have
impaired your ability to operate your vehicle. Alcohol and certain drugs delay reaction time, impair judgment
and reduce coordination, which could lead to an accident that could result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers or pedestrians might
make and be ready to avoid acci- dents.
Driver distraction: Always give your
full attention to driving. Anything that distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you, your occupants or others.
QGeneral precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to have or use the key.
Children may be able to start the vehi- cle or shift the vehicle into neutral. There is also a danger that children
may injure themselves by playing with the side windows, the panoramic moon roof, or other features of the
vehicle. In addition, heat build-up or extremely cold temperatures inside the vehicle can be fatal to children.

Plug-in hybrid system features
The plug-in hybrid system is a system excellent in both economical
efficiency of electric vehicles and practicality of Plug in Hybrid Elec-
tric Vehicles.
EV driving can be performed using electricity charged from an external
power source.
*
If the amount of electricity remaining in the hybrid battery (traction bat-
tery) becomes low, the vehicle 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 accordance 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 gasoline engine may also be
used simultaneously in accordance with driving conditions.

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 display when the switch is pressed.)
OWhen electricity needed for EV driving is not remaining (when in EV mode or AUTO EV/HV mode)
OWhen the traction battery is almost completely charged (hybrid battery
[traction battery] charge mode)
QWhen switching from EV mode to another mode using the switch
OAfter switching from EV mode to HV
mode or hybrid battery (traction bat- tery) charge mode and the power
switch is turned off, the system returns to EV mode the next time the
vehicle is started.*
OAfter switching from EV mode to
AUTO EV/HV mode and the power switch is turned off, the system does not return to EV mode the next time
the vehicle is started.*
*: If there is not enough charge remain-
ing in the hybrid battery (traction bat-
tery) to allow EV driving, the system
switches to HV mode.
QHybrid battery (traction battery) charge mode
OThe following may occur to protect the system, etc.• Cannot switch to hybrid battery (trac-
tion battery) charge mode or cannot cancel it• Gasoline engine does not start or
stops even after switching to hybrid battery (traction battery) charge mode
OIf 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 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 bat-tery (traction battery) may not be per-
formed.
QWhen in EV mode
In EV mode, EV driving (driving
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.90). Also, if a little electricity is
remaining in the hybrid battery
(traction battery), HV mode is auto-
matically 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

WARNING
QWhen using the hybrid battery (traction battery) charge mode
Observe the following precautions
when using the hybrid battery (trac- tion battery) charge mode while park-ing.
Failure to do so may lead to death or serious health hazard, as the gasoline engine operates when in the hybrid
battery (traction battery) charge mode.
ODo not stop the vehicle near flam-
mable materials.
ODo not use the hybrid battery (trac-
tion battery) charge mode in a closed area where ventilation is insufficient, such as in a garage or
area with snow buildup.

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).

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.

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

QHybrid battery (traction bat-
tery) warming control (Green-
land only)
This control operates after the AC
charging cable remains connected
to the vehicle for 3 days and “Bat-
tery Heater” automatically stops. It
automatically insulates the hybrid
battery (traction battery) in
extremely low temperatures.
This control stops 31 days after
the AC charging cable is con-
nected, even if it is still con-
nected to the vehicle.
When this control operates,
charging schedule settings are
ignored and charging starts.
Q“Battery Cooler”
When the hybrid battery (traction
battery) is hot and the AC charging
cable is connected to the vehicle,
this function cools the hybrid bat-
tery (traction battery) before
charging is carried out.
“Battery Cooler” will operate when
the “Battery Cooler” of the
“Charging Settings” on the multi-
information display is on. (P.185)
QTraction battery heating and cool-
ing system (“Battery Heater” and
“Battery Cooler”)
OThe system operates when the hybrid
battery (traction battery) is below or
above a certain temperature.
OThe system may operate when
charging is not being performed.
OWhen the charging schedule is used
(P.143), this function will operate according to the charging schedule.
Q“Battery Heater”
OWhen “Battery Heater” is operating,
the charging indicator illuminates.
OWhen the AC charging cable is
removed from the vehicle or remains
connected to the vehicle for approxi-
mately 3 days, the system automati-
cally stops.
OWhen “Battery Heater” is operating
during charging, the charging time
may be longer than normal.
OIf the outside temperature becomes
high while “Battery Heater” is operat-
ing, charging may complete earlier
than the “Departure” time set.
(P.143)
OWhen the traction battery is almost
completely charged, “Battery Cooler”
may not be implemented.
OWhen the following operations are
performed while “Battery Heater” is
operating, the hybrid battery (traction
battery) heating operation stops.
• The shift lever is changed to any posi-
tion other than P
• The Remote Air Conditioning System
is operated (P.414)
O“Battery Heater” may operate even
when the hybrid battery (traction bat-
tery) is fully charged depending on the
temperature of the hybrid battery
(traction battery).
• The remaining charge of the hybrid
battery (traction battery) decreases
when “Battery Heater” operates. The
charging operation may start again to
charge the hybrid battery (traction bat-
tery).
• “Charging Stopped Due to Pulled
Charging Connector” may be shown
when the charging connector is
removed while recharging. (P.159)
Q“Battery Cooler”
OThe charging indicator is illuminated
while “Battery Cooler” is on standby or
operating.
O“Battery Cooler” is implemented for a
