■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

●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.
■When the outside rear view mir-
ror defoggers are operating
Do not touch the rear view mirror sur- faces when the outside rear view mir-
ror defoggers are on.
