Windshield fog detection function
When automatic mode is set, the humidity sensor (
→
P. 535) 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 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
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.
■
Operation of the air conditioning system in the air conditioning eco
mode
●
In the air conditioning 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
• Turn off the air conditioning eco mode
●
When the driving mode is set to Eco driving mode, the air conditioning eco
mode will be turned on automatically. Even in this case, the air conditioning
eco mode can be turned off by selecting . (

The dehumidification function may not operate even when is
selected.
■
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.
