■ Heating
● In HV mode, the gasoline engine may operate in order to exhaust 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 con-
ventional 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.
Outside heat exchanger
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing (P. 516). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When
is turned on, the heating is controlled optimally. Therefore,
the set heating performance may not be achieved even if the fan speed
setting is increased.

● In the following situations the gasoline engine may operate in order to
exhaust heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately -10°C or low
•
is operating
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after
is pressed.

■ Water droplets during air conditioning operation
The outside heat exchanger, accumulator
Accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, 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
on will dehumidify the air from the outlets and defog the
windshield effectively.
●If you turn
off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 515) detects fog on
the windshield and controls the air conditioning system to prevent fog.
■ Outside/recirculated air mode
● When driving on dusty roads such as tunnels or in heavy traffic, set
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During cooling operation, setting the recircu-
lated air mode will also cool the vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.
6
■ Operation of the air conditioning system when the blower customization
is set to “ECO”
● In the “ECO” mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Adjust the temperature setting
• Set the blower customization to “FAST” or “NORMAL” mode.
● When the driving mode is set to Eco driving mode, the fan speed setting
mode will be changed to “ECO” mode automatically. Even in this case, the
fan speed control mode can be changed by pressing
. (P. 412)
■ When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when
is pressed.

6-1. Using the air conditioning system and defogger
■ Ventilation and air conditioning odors
● To let the fresh air in, set the air conditioning 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.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring, 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.
■ Air conditioning filter
P. 609
■ Customization
Settings (e.g. A/C auto switching operation) can be changed.
(Customizable features: P. 708)
WARNING
■ To prevent the windshield from fogging up
●Do not use
during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
●Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.

sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. (P. 513)
Follow these points to avoid damaging
the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sensor or subject it to strong impacts
●Do not stick anything on the sensor
■ To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
■ Air outlets
The air outlets become hot when used for heating. Therefore, use caution
and adjust the air outlets accordingly.

Remote Air Conditioning System
The Remote Air Conditioning System uses electrical energy
stored in the hybrid battery (traction battery) and allows the air
conditioning to be operated by remote control.
If the Remote Air Conditioning System is used while the charging
cable is connected to the vehicle, the reduction of charge in the hybrid
battery (traction battery) will be suppressed to allow you to use elec-
tricity from an external power source.
Charging will be conducted automatically after the Remote Air Condition-
ing System is stopped.
Before leaving the vehicle
Check the temperature setting of the air conditioning system.
(P. 504)
The Remote Air Conditioning System will operate in accordance with the
temperature settings of the air conditioning system.
Activating the Remote Air Conditioning System
Press and hold “A/C” on the wire-
less remote control to operate the
Remote Air Conditioning System.
The system will shut off if a door is
opened.
The system can be stopped by
pressing “A/C” twice.

■ Operating conditions
The system will only operate if all of the following conditions are met:
● The shift position is in P.
● The power switch is off.*
●All doors are closed.
●The hood is closed.
*: The Remote Air Conditioning System cannot be used for approximately 3
minutes and a half after the power switch is turned off.
■ Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
● About 10 minutes have passed since operation began
● Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (traction
battery) drops to low.
■ Conditions affecting operation
The system may not start in the following situations:
● The charge level of the hybrid battery (traction battery) is low
●The outside temperature is extremely low
● When the hybrid system is cool (for example, after being left for a long time
in low temperatures)
■ Windshield defogger
6
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient 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
temperature.
■ Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal opera-
tion.
■ Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The emergency flashers flash to indicate that the doors have been locked
or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)
