Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn 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. 264) detects fog on
the windshield and controls the air conditioning system to prev ent fog.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to recirculated air mode. Thi s is effective in
preventing outside air from entering the vehicle interior. Duri ng cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
■ Operation of the air conditioni ng system in ECO HEAT/COOL mode
● In ECO HEAT/COOL mode, the air conditioning system is controlle d as fol-
lows to prioritize fuel efficiency:
• Fluid (heating) heater 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 temperature settings and fan speed
• Touch while in , and is set
• Touch while in , and ECO HEAT/COOL mode is canceled
■ Operation of the air conditioning system in Eco drive mode
When ECO MODE switch is pressed, operations switch over to ECO HEAT/
COOL mode. ( P. 183)
■ When the outside temperature exceeds 75°F (24°C) and the air co ndition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing 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 pre ssing .

When the outside t emperature is low
The dehumidification function may not operate even when is pre ssed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in aut omatic
mode.
■ Air conditioning filter

04 (about 0.12 sec.) 05 (about 0.14 sec.)
With the desired setting displayed, without switching over the screen by
performing touch operations for about 5 seconds, when the power

WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weathe r.
The difference between the temperature of the outside air and t hat of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
● Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers 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.
NOTICE
■Humidity sensor
■ To prevent 12-volt b attery discharge
Do not leave the air conditioning system on longer than necessa ry when the
fuel cell system is off.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc., is installed. ( P. 261)
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor
● Do not spray the glass cleaner on the
sensor or subject it to strong impacts
● Do not stick anything on the sensor
