■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 t emperature 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 situat ion, the air temperature
from the outlets may not change even though the set tem perature 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 controlle d 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 ea sily fog up when
the humidity in the vehicle is high.
Turning “A/C” s witch 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 powe r and then press
.
●When the outside te mperature 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 o n dusty roads
Close all windows. If dust thrown up by
the vehicle is still d rawn 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 recir culated air mode
temporarily is recommended in pre - venting dirty air from entering the
vehicle interior and helping to cool the
vehicle when the ou tside 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 res trict heating/cool-
ing capacity
• Fan speed restrict ed 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
odors
●To let fresh air in, set the air condition -
ing system to the outside air mode.
