■ Outside/recirculated air mode
● When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on the tempera-
ture setting or the inside temperature.
■ When the outside temperature is low
The dehumidification function may not operate even when “A/C” is selected.
■ 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
■ 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 accu-
mulate 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.
