■ Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem 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:
● Turn off eco air conditioning mode
(P.347)
● Adjust the fan speed
● Turn off Eco drive mode (P.325)

nearly 32°F (0°C)
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 sys-
tem. This may then cause odor to be
emitted from the vents.
● To reduce potential odors from occur-
ring:
• It is recommended that the air condition-
ing 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 imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on.
● When parking, the system automatically
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle.
■ Using the voice control system
