Interior features
When the outside temperature is low
The dehumidification function may not operate even when “A/C” is pressed.
Operation of the air conditioning system in Eco drive mode
In the Eco drive 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
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. (P. 658)
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
immediately after the air conditioning system is started in automatic mode.
Air conditioning filter
P. 527
Customization
Settings (e.g. A/C automatic mode switch operation) can be changed.
