Plug-in hybrid system
■HV mode
When in HV mode, the vehicle
is driven using both the gaso-
line engine and electric motor.• If electricity needed for EV driving in EV mode or AUTO
EV/HV mode is not remain-
ing, 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.
Switching to HV mode when driving on a highway or when driv-
ing uphill is recomme nded in order to conse rve battery power.
When in HV mode, the HV drive mode indicator illuminates.
■
Hybrid battery (traction battery) charge mode
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.
• Charging time differs depending on the driving state of the ve hi-
cle when driving in hybrid batte ry (traction battery) charge mode.
When in the hybrid battery (traction battery) charge mode, the hybrid
battery charge mode indicator illuminates.

3. Things you must know
Things you must know
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the rech arging 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.
■ Gasoline engine operation in EV mode or AUTO EV/HV mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range is being displayed on the multi-
information display, EV driving (driving using only the electri c motor) may be
canceled and both gasoline engine and electric motor are used depending on
the situation (EV driving will be returned to automatically aft er EV driving
becomes possible again).
EV driving may be canceled automatically in the following circu mstances
*1:
● When vehicle speed is more than approximately 84 mph (135 km/h) .
● When power is needed temporarily, for example when the accelera tor pedal
is depressed firmly or when accelerating suddenly.
*2
● 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 14°F (-10°C).
● When the windshield defogger switch is pressed.
● When the system determines that the gasoline engine needs to be started.
*1: The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.
*2: When driving in AUTO EV/HV mode. Even in EV mode, the gasolineengine may start, depending on the condition of the hybrid battery (traction
battery).
