Due to natural language speech recognit ion technology, this system enables rec-
ognition of a command when spoken na turally. However, the system cannot rec-
ognize every variation of each command.
In some situations, it is possible to omit the command for the procedure and
directly state the desired operation.
This function is available in English, Spanish and French.

Interior features
■When the outside temperature exceeds 75 F (24 C) and the air conditioning system
is on
●In order to reduce the air co nditioning power consumption, the air conditioning system
may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the power switch is turned to
ON mode.
●It is possible to switch to outside air mode at any time by pressing the outside/recircu-
lated air mode button.
■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.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting “A/C”
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. 521) 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 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 enteri ng the vehicle interior. During cooling operation, setting 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” 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 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 dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.
■Air conditioning filter
P. 625
■Customization
Some functions can be customized ( P. 736)
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.
●Do not touch the glass at lower part of the windshield or to the side of the front pillars
when the windshield wiper de-icer is on. (if equipped)
●Do not place anything on the instrument
panel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.

items, the lighter may catch fire or the spray can may release gas, causing a fire
hazard.
