Plug-in hybrid system control
The plug-in hybrid system feat ures both EV mode and HV mode,
which are switched automatically. When a sufficient amount of elec-
tricity is remaining in the hybrid ba ttery (traction battery) the vehicle
can be driven as an electric vehicle in EV mode; and when only a lit-
tle electricity is remaining in the hybrid battery (traction battery), HV
mode is automatically selected and the vehicle can be used in the
same manner as a hybrid vehicle.
The modes can also be switched using the EV/HV mode selection
switch. ( P. 37)
■ EV mode
Using the electricity stored in the
hybrid battery (traction battery),
the vehicle can be driven using
only the electric motor (traction
motor).
The gasoline engine may also be
used temporarily at the same
time in accordance with the
speed and load of the vehicle,
and with heater usage.

■Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source, however the gasoline engine that is provided on board as
an auxiliary power source and as a power source for driving in HV mode
needs to be filled with fuel. Check the fuel amount and refill immediately
when the fuel level becomes low. ( P. 174)
■ 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. 58, 268) is being displayed,
the gasoline engine may operate automatically in the following circum-
stances (EV driving will be returned to automatically after EV driving
becomes possible again):
● When the heater etc. is in use.
● 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.
The vehicle has been left in temperatures lower than about 32 °F (0 °C)
for a long period of time etc.
● When power is needed temporarily, for example when accelerating sud-
denly.
● When vehicle speed is more than approximately 62 mph (100 km/h).
● When the accelerator pedal is depressed firmly or the vehicle is on a hill
etc.
● When the outside temperature is low (less than 14 °F [-10 °C])
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.

When continually using EV mode only
After driving for approximately 124 miles (200 km) with the gasoline engine
off, the gasoline engine may start for a short amount of time in order to pro-
tect the system.
■ 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
● When the temperature of the hybrid battery (traction battery) is high or
low
● During hybrid battery (traction battery) charging
● When the heater is switched on
*: 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, 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.)

■Highway driving
Control your speed and keep at a constant speed. Also, before
stopping 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 reta ined when slowing down.
Electricity consumptio n will increase substantially when driving
at high speeds in EV mode. If ther e will be a long distance to the
next external charging point afte r leaving a freeway, driving in
HV mode while on the freeway and in EV mode after leaving the
freeway is recommended.
■ Air conditioning on/off
●Switch the air conditioning ( ) to off when it is not
needed. Doing so can help cont rol excessive electricity and
fuel consumption.
In summer: In high temperatures, use the recirculated air
mode. Doing so will help to reduce the burden on the air con-
ditioner and reduce fuel consumption as well.
In winter: Because the gasoli ne engine will not automatically
cut out until the gasoline engine and the interior of the vehicle
are warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
● For efficiency, use the Remo te Air Conditioning System
before departing while the c harging cable is connected.

CAUTION
■
Power sources precautions
Observe the following precautions.
If you do not follow them, fire, electrical shock or damage may occur, possi-
bly resulting in death or serious injury.
● Connect to an AC 120 V outlet (NEMA 5-15R) with a Ground-Fault Circuit-
Interrupter (GFCI) and supplied by a circuit breaker per your local code.
Use of a 15A individual circuit is strongly recommended.
● Use of a block heater for charging is prohibited.
●Do not connect the charging cable to a
multi-outlet adapter, multi-plugs, or con-
version plug.
● Connecting the charging cable to an
extension cord is strictly prohibited. The
extension cord may overheat and does
not contain a Ground-Fault Circuit-
Interrupter (GFCI).
● Do not connect to a power strip.

As shown below, the driving conditions of the vehicle can be con-
firmed by checking the status of the indicator bar.
*1: The images are examples only, and may vary slightly from actual condi- tions.
*2: If the gasoline engine is operated (for example when driving at highspeeds or using the heater), the EV indicator may turn off even if the bar
is in the EV driving area. ( P. 40)
