NX300h_U_OM78007U ■
Fogging up of the windows ●
The windows will easily fog up when the humidity in the vehicle is high. Pressing “A/C”
button or selecting “A/C” will dehumidify th e air from the outlets and defog the wind-
shield effectively. ●
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. ■
Windshield fog detection function
When automatic mode is set, the humidity sensor (  P. 4 3 9 ) d e t e c t s f o g o n t h e w i n d -
shield 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 outside 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 automati cally switch depending on the tempera-
ture setting or the inside temperature. ■
When the outside temperature is low
The dehumidification function may not operat e even when “A/C” is pressed or “A/C” is
selected. ■
Operation of the air conditioning system in Eco drive mode ●
In the Eco drive mode, the air conditioning sy stem 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 performa nce, 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 conditio ning 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 dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.■
