Interior features
■Fogging up of the windows
●The windows will easily fog up when the humi dity in the vehicle is high. Selecting “A/C”
on the option control screen will dehumidify the air from the outlets and defog the
windshield 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. 393) detects fog on the wind-
shield and controls the air cond itioning system to prevent fog.
■Outside/recirculated air mode
●When driving on dusty roads, in tunnels, or in heavy traffic, set to the
recirculated air mode. This is effective in preventing outside air from entering the vehi-
cle interior. During cooling operation, settin g the recirculated air mode will also cool
the vehicle interior effectively.
●Outside/recirculated air mode may automa tically 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” on the option control
screen is selected.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold, the fol-
lowing may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollen is filtered out ev en if the micro dust and pollen filter is turned off.
■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 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.
• Immediately after the air conditioning system is started in automatic mode, the start
timing of the blower may be delayed for a short period of time.
■Air conditioning filter
→ P. 476
■Customization
Settings (e.g. A/C automatic mode sw itch operation) can be changed.
(Customizable features: →P. 568)
WARNING
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause
the outer surface of the windshield to fog up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Vehicles with windshield wiper de-icer: Do not touch the glass at lower part of the
windshield or to the side of the front pill ars when the windshield wiper de-icer is on.
●Do not place anything on the instrument
panel which may cover the air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
