Plug-in hybrid system features

The illustration is an example for explanation and may differ from the
actual item.

Gasoline engine
Electric motor (traction motor)

The plug-in hybrid system is a system excellent in both econom-
ical efficiency of electric vehicles and practicality of hybrid vehi-
cles.

●

EV driving can be performed using electricity charged from an
external power source.

●

If the amount of electricity remaining in the hybrid battery (traction
battery) becomes low, the vehicle is automatically controlled in
such a way that it can be driven as a hybrid 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 gaso-
line engine may also be used simultaneously in accordance with driving
conditions.

EV City mode (



P. 88)

When a sufficient amount of electricity for EV driving is remaining in
the hybrid battery (traction battery)

, the operation mode can be

switched to EV City mode.
EV City mode limits motor output and minimizes the operation of
the gasoline engine.

Therefore, the vehicle can be driven with

only electric motor (traction motor) in city areas, etc.

When in EV City mode, the EV City mode indicator illuminates.

: The amount of remaining charge can be checked on the multi-informa-

tion display etc. (



P. 232)

: When acceleration is required, fully depress the accelerator pedal to

start the gasoline engine.

HV mode
When in HV mode, the vehicle is driven using both the gasoline
engine and electric motor (traction motor). (



P. 92)

●

If electricity needed for EV driving in EV 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. 88). 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 City mode indi-
cator turn off.

: The EV driving range may reduce even after switching to HV mode.



P. 89)

Electricity generated in the gasoline engine can be charged in the
hybrid battery (traction battery) by switching to the hybrid battery
(traction battery) charge mode when electricity needed for EV driv-
ing is not remaining.*

●

The system may not be able to switch to the hybrid battery (trac-
tion battery) charge mode due to the state of the plug-in hybrid
system. (

P. 90)

●

Charging time differs depending on the driving state of the vehi-
cle when driving in hybrid battery (traction battery) charge mode.

When in the hybrid battery (traction battery) charge mode, the hybrid
battery charge mode indicator illuminates.

: When in the hybrid battery (traction battery) charge mode, the hybrid

battery can be charged while driving. However, the gasoline engine runs
to charge the battery and fuel consumption becomes higher compared
with driving in HV mode.

2-1. Plug-in hybrid system

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.

When in EV mode

In EV mode, EV driving (driving using only the electric motor)

possible. However, depending on the situation, EV driving may be
canceled and both gasoline engine and electric motor are used
(



P. 94). 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 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 dis-

play etc. (



P. 215, 231, 238, 255)

■

When in EV City mode

In EV City mode, EV driving (driving using only the electric motor) is
possible.

●

Motor output is limited at the same level unless the accelerator
pedal is fully depressed.
When it is necessary to accelerate the vehicle, depress the
accelerator pedal completely or cancel EV City mode as needed.

●

In the following situations, EV City mode is automatically can-
celed.

• When driving in EV driving is not possible. (



P. 94)

• When Dynamic radar cruise control with full-speed range is

activated.

• When the accelerator pedal is fully depressed.

: The EV driving range can be checked using the multi-information dis-

play etc. (

P. 215, 231, 238, 255)

: Depending on the circumstances, EV City mode may also be canceled

in situations other than those above.

Control when driving in each mode

2-1. Plug-in hybrid system

■

When in HV mode

The vehicle can be used in the same way as a standard hybrid
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 vehi-
cle.

●

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).

●

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 battery) requires charging or the

engine is warming up, etc., the gasoline engine will not automatically
stop. (



P. 95)

■

When braking (regenerative braking)

The electric motor (traction motor) charges the hybrid battery (trac-
tion battery).
The EV driving range can be extended by actively using this regen-
erative braking to store electricity in the hybrid battery (traction bat-
tery).
Moreover, as fuel consumption is also reduced when in HV mode,
the regenerative braking system can be used effectively.

tem

In order to make EV/EV City mode
available, charge the hybrid bat-
tery (traction battery) from an
external power source before
using the vehicle.

Even if charging the hybrid battery
(traction battery) has not been
completed, the vehicle can be
driven. However, if there is not
enough charge remaining, it is pos-
sible that the vehicle cannot be
driven in EV/EV City mode or the
EV driving range will become
shorter.

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 (16 mph).

■

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

●

While the GPF system (



P. 508) is operating to regenerate the exhaust gas

filter, the hybrid battery (traction battery) may not be recharged.

■

EV driving range

●

The EV driving range is displayed on the multi-information display etc.
(



P. 215, 231, 238, 255)

●

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. (

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-
information display and EV mode will be automatically switched 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. 351)

■

Gasoline engine operation in EV mode

Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range (



P. 215, 231, 238, 255) is being

displayed on the multi-information display etc., EV driving (driving using only
the electric motor) may be canceled and both gasoline engine and electric
motor are used depending on the situation (EV driving will be returned to
automatically after EV driving becomes possible again).
EV driving may be canceled automatically in the following circumstances:

●

When vehicle speed is more than approximately 135 km/h (84 mph).

●

When power is needed temporarily, for example when the accelerator pedal
is depressed firmly or when accelerating suddenly.

●

When the temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.

●

When the temperature of the hybrid system is low.

●

When the heater is switched on when the outside temperature is below
about -10



C (14



F).

●

When the windshield defogger switch is pressed. (



P. 527)

●

When the system determines that the gasoline engine needs to be started.

The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.

Conditions in which the gasoline engine may not stop

The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions

●

During gasoline engine warm-up

●

During hybrid battery (traction battery) charging

●

When the temperature of the hybrid battery (traction battery) is high or low

●

When the windshield defogger switch is pressed. (



P. 527)

: Depending on the circumstances, the gasoline engine may also not stop

automatically in situations other than those above.

■

If the vehicle is not used for a long time

●

The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(



P. 594)

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 vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to controls, such
as the system checking, operating. When the charging cable is not needed,
immediately remove it from the vehicle.

●

For vehicles with solar charging system, please refer to P. 181.
