■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize 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
• Turn off Eco drive mode
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur:
●Immediately after the “AUTO” switch is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

■When the hybrid battery cooling system operates
●If the hybrid battery cooling system operates when the air conditioning is off, a
message will be shown on the multi-information display and the air conditioning will
automatically turn on. ( P. 121)
●The sound of the air flow may change when cool air flows from the rear roof vents
or the air purifier is in operation. This occurs when the hybrid battery is being
cooled and does not indicate a malfunction.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Pollen removal mode
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the pollen removal mode is turned off.
■Air purifier (with rear air conditioning system)
The air purifier will turn on when turning the rear air conditioning system on.
■When the outside temperature falls to nearly 0 C (32F)
The dehumidification function may not operate even when “A/C” is selected.

■Ventilation and air conditioning odors
●To let 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.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning 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 immedi-
ately after the air conditioning system is started in automatic mode.
■nanoe *1
Your vehicle incorporates a nanoe device, which is considered a biocidal product.
The nanoe  device generates charged water particles from the ambient air. These
particles purify the air in the cabin by suppressing bacteria.
The nanoe  device is considered a biocidal product in the EU according to the
interpretation of Regulation (EU) No 528/2012.
Active substances: Charged water particles (nano) containing hydroxyl radicals,
generated from ambient air
nanoe  helps to provide purified air by emitting electrically charged water particles
through the front center vent on the driver’s side*2.
●When the fan is turned on and “nanoe” on the option control screen is selected, the
nanoe  is activated.
●When the fan is operated in the following conditions, system performance will be
maximized. If the following conditions are not met, the nanoe  may not operate at
full capacity.
• The , or air outlets are being used.
• The front center vent on driver’s side is open.
●When nanoe  is generated, a small amount of ozone is emitted and may be faintly
smelled in some situations. However, this is approximately the same as the amount
that already exists in nature, such as in forests, and it has no affect on the human
body.
●A slight noise may be heard during operation. This is not a malfunction.

*2: According to temperature and humidity conditions, fan speed and direction of the
air flow, the nanoe  may not operate at full capacity.
