■Heating
●In HV mode, the gasoline engine
may operate in order to extract
heat from the engine coolant via
the heater.
●In EV mode, heating is done by a
heat pump system.
• When the outside temperature is low or it is snowing, compared to
conventional vehicles, heating
may be less effective and warm
air may not come out.
• When the outside heat exchanger is frosted over, fan speed declines
and it may become harder to heat
the interior.
However, it is not a malfunction. In
this situation, the air temperature
from the outlets may not change
even though the set temperature is
raised.
• If frost has formed of the outside heat exchanger, the heating per-
formance will decline. The frost
can be removed from the outside
heat exchanger by operating the
Remote Air Conditioning System
before driving ( P.405). When
frosted over, the heating operation
of the Remote Air Conditioning
System starts after defrosting.
• When “AUTO” switch is turned on,
the heating is controlled opti-
mally. Therefore, the set heating
performance may not be achieved
even if the fan speed setting is
increased.

Outside heat exchanger
●In the following situations the gas-
oline engine may operate in order
to extract heat from the engine
coolant via the heater even in EV
mode.
• The outside temperature is approximately 14° F (-10°C) or low
• is operating
■Water droplets during air condi-
tioning operation
The outside heat exchanger, accu-
mulator and air conditioning piping
may incur condensation or frost may
form.
During or after the air conditioning
operation, water droplets may fall
from the vehicle. However, it is not a
malfunction.

■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C ” switch on will
dehumidify the air from the outlets
and defog the windshield effec-
tively.
●If you turn “A/C” switch off, the
windows may fog up more easily.
●The windows may fog up if the
recirculated air mode is used.
■While using “My Room Mode”
●It may not be possible to obtain
the intended defogging perfor-
mance even if is pressed.
If the windows need to be
defogged before driving, stop
charging power and then press
.
●When the outside temperature is
low, heating may feel insufficient
due to restricted operation of the
air conditioning.
Heating cannot be performed
when it is 14°F (- 10°C) or less as
the gasoline engine cannot be
started during “My Room Mode”. If
heating is desired, stop charging
and remove the AC charging
cable from the vehicle.
■When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode
and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.

WARNING
■Precautions for the Remote
Air Conditioning System
●Do not use the system if people
are in the vehicle.
Even when the system is in use,
the internal temperature may
still reach a high or low level
due to features such as the
automatic shut-off. Children and
pets left inside the vehicle may
suffer heatstroke dehydration or
hypothermia or could result in
death or serious injury.
●Depending on the surrounding
environment, signals from the
wireless switch may transmit
further than e xpected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when neces-
sary.
●Do not operate “A/C” on the
wireless remote control if the
hood is open. The Remote Air
Conditioning System may oper-
ate unintentionally and objects
may be drawn into the electrical
cooling fan.
