■Gasoline engine operation in EV/EV auto mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range ( P. 207, 223, 230, 247) is being
displayed on the multi-information display etc., EV driving (dr iving using only
the electric motor) may be canceled and both gasoline engine an d 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 circu mstances:
● 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.
*
● 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. ( P. 500, 510)
● When the system determines that the gasoline engine needs to be started.
The gasoline engine may also operate in circumstances other tha n those
listed above, depending on conditions.
*: When traveling in the EV auto mode only
■ 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. 500, 510)
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.

◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) off when it is
not needed. Doing so can help reduce excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on th e
air conditioning system and reduc e electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the heated steering w heel (if equipped) and seat heat-
ers is effective. ( P. 5 2 2 )
● Using the Remote Air Conditioning System ( P. 518) while the
charging cable is connected to the vehicle can reduce electrici ty
consumption immediately after st arting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode a nd
setting “Climate Prep” to “On” c an reduce electricity consumption
immediately after starting off by operating air conditioning be fore
charging is completed. ( P. 154)
*1: Vehicles with 7-inch display
*2: Vehicles with 11.6-inch display
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If t here is
improper tire inflation pressur e in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead t o increased fuel and electricity consumptio n.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

■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 l ocal code.
Use of a 15A individual circuit is strongly recommended.
● Use of a block heater for charging is prohibited.
● Make sure to connect the charging connector and charging inlet directly.
Do not connect a converting adaptor or extension cord between t he
charging connector and charging inlet.
● Do not connect the charging cable to a
multi-outlet adapter, multi-plugs, or con-
version plug.
