■Defogging the rear window
and outside rear view mirrors
Defoggers are used to defog the
rear window, and to remove rain-
drops, dew and frost from the out-
side rear view mirrors.
Press the rear window and outside
rear view mirror defoggers switch.
The defoggers will automatically turn off
after 15 minutes.

Normal  “ECO”  “FAST”
■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.438).
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

■Water droplets during air condi-
tioning operation
The outside heat exchanger, accumula-
tor 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 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.411)
• Turn off blower customization
(P.432)
■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.
●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.
■Using the voice control system (if equipped)
Air conditioning system can be operated using the voice control system. For details regarding the voice control sys-
tem, refer to the “Multimedia owner’s manual”.
■Air conditioning filter
 P.500
■Noise from air conditioning system
Approximately 90 seconds after the power switch turned to OFF, you may hear sound coming from air conditioning
system. This is the sound of a air condi- tioning system initialize and, it does not indicate a malfunction.
■Customization
Settings (e.g. A/C Auto switch opera- tion) can be changed.(Customizable features: P.607)
1Press the “AUTO” switch.
The dehumidification function begins to operate. Air outlets and fan speed are automatically adjusted according to the

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.
