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
