3996-1. Using the air conditioning system and defogger
6
Interior features
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.
Accumulator
Outside heat exchanger
■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.

4006-1. Using the air conditioning system and defogger
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally. This may also reduce fuel
consumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
●It is possible to switch to outside
air mode at any time by pressing
the outside/recirculated air mode
switch.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air conditioning perfor-
mance, perform the following
operations:
• Turn off Eco drive mode ( P.377)
• Turn off Eco air conditioning mode
●When the driving mode is set to
Eco driving mode, the Eco air con-
ditioning mode will be turned on
automatically. Even in this case,
the Eco air conditioning mode can
be turned off by pressing the Eco
air conditioning mode switch.
■When the outside temperature
falls to nearly 32°F (0°C)
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 condi-
tioning 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
occurring:
• It is recommended that the air conditioning system be set to out-
side 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 con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
■Air conditioning filter
 P.483
■Air conditioning system refrig-
erant
●A label regarding the refrigerant of
the air conditioning system is
attached to the h ood at the loca-
tion shown in the following illustra-
tion.
●The meaning of each symbol on
the label are as follows:
Caution
Air conditioning system

4066-1. Using the air conditioning system and defogger
cient due to the power being
restricted more than during normal
air conditioning operation. Also, the
outside of the windshield may fog up
due to the outside temperature,
humidity or air conditioning set tem-
perature.
■Using the heater via the Remote
Air Conditioning System
●When the outside temperature is
low, heating may feel insufficient
due to restricted operation of the
air conditioning.
●When the outside heat exchanger
becomes frosted over, heating
performance may decline due to
automatically switching to the frost
removal operation. ( P.396)
■Security feature
Any unlocked doors will be automat-
ically locked when the system is
operating. The buzzer sounds and
the emergency flashers flash to indi-
cate that the doors have been
locked or the system has been
turned off.
■Conditions affecting operation
 P.218
■While the Remote Air Condi-
tioning System is operating
●Depending on the operating con-
dition of the Remote Air Condition-
ing System, the air conditioning
compressor or cooling fan may
spin and an operating noise may
be heard. However, this does not
indicate a malfunction.
●The air conditioning operation
switches, etc. will not operate
while the Remote Air Condition-
ing System is operating.
■Electronic key battery depletion
 P.194
■When the electronic key bat-
tery is fully depleted
 P.493
■Customization
Setting (e.g. Operation using “A/C”
on the wireless remote control) can
be changed. (Customizable fea-
tures: P.569)
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.
NOTICE
■To prevent the hybrid battery
(traction battery) from being
discharged
Use “A/C” on the wireless remote
control only when necessary.
