■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 conven-
tional 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 inte-
rior. 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 performance
will decline. The frost can be removed
from the outside heat exchanger by
operating the Remote Air Conditioning
System before driving (P.460).
When frosted over, the heating opera-
tion of the Remote Air Conditioning
System starts after defrosting.
• When “AUTO” switch is turned on, the
heating is controlled optimally. There-
fore, the set heating performance may
not be achieved even if the fan speed
setting is increased.
Outside heat exchanger
●In the following situations the gasoline
engine may operate in order to extract
heat from the engine coolant via the
heater even in EV mode.
• The outside temperature is approxi-
mately -10°C (14°F) or low

■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 dehumid-
ify the air from the outlets and defog
the windshield effectively.
●If you turn “A/C” switch off, the win-
dows may fog up more easily.
●The windows may fog up if the recir-
culated air mode is used.
■While using “My Room Mode”
●It may not be possible to obtain the
intended defogging performance 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 condi-
tioning. Heating cannot be performed
when it is -10°C (14°F) 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 vehi-
cle.
■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 recom-
mended 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 recommended in pre-
venting dirty air from entering the
vehicle interior and helping to cool the
vehicle when the outside air tempera-
ture is high.
●Outside/recirculated air mode may
automatically switch depending on the
temperature setting or the inside tem-
perature.
■Operation of the air conditioning
system in Eco drive mode
●In Eco drive mode, the air conditioning
system is controlled as follows to pri-
oritize fuel efficiency:
• Engine speed and compressor opera-
tion controlled to restrict heating/cool-
ing capacity
• Fan speed restricted when automatic
mode is selected
●To improve air conditioning perfor-
mance, perform the following opera-
tions:
• Turn off Eco drive mode (P.434)
• Turn off blower customization
(P.454)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not
operate even when “A/C” switch is
pressed.
■Ventilation and air conditioning

4566-1. Using the air conditioning system and defogger
●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●To reduce potential odors from occur-
ring: • It is recommended that the air condi-tioning system be set to outside air
mode prior to turning the vehicle off. • The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
●When parking, the system automati-cally switches to outside air mode to encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

WARNING
■Cautions for using “My Room Mode”
Do not leave children, people who need assistance, or pets inside the vehicle. The system may turn off
automatically and the interior tem- perature may become high or low, resulting in heat stroke, dehydration
or hypothermia. Failure to do so may result in death or serious injury.
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather.The difference between the tempera-
ture of the outside air and that of the windshield can cause the outer sur-face of the windshield to fog up,
blocking your vision.
