Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
Humidity sensor
Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high.
Selecting on will dehumidify the air from the outlets and defog the
windshield effectively.
If you off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
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 the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculated air mode will also cool the vehi-
cle interior effectively.
Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature. A sensor, which detects humidity inside
the vehicle and the temperature of the
windshield, is provided to detect fog on
the front windscreen. Due to the sensor,
when automatic mode is set the air condi-
tioning may make the following controls:
Changing the amount of air flow
Changing the amount of air introduced
from outside when in outside air mode
with the air vents in the position
Changing the settings of the air vents to
when the is set

automatically 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.
Pollen removal mode
In order to prevent the windshield from fogging up when the outside air is
cold, the following 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 pollens are filtered out even if the pollen removal mode is turned off.
When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when is selected.
Air conditioning odors
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.
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 delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
