This feature is used to prevent ice from
building up on the windshield and wiper
blades.
The windshield de-icer will automatically
turn off after a while.
■Micro dust and pollen filter
Outside air mode switches to
(recirculated air) mode. Pollen is removed
from the air and the air flows to the upper
part of the body.
Usually the system will automatically turn
off after a while.
In order to prevent the windshield from fog-
ging up when the outside air is cold, the
dehumidification function may operate or
the outside/recirculated air mode may not
switch to (recirculated air) mode.
Pollen is filtered even if the micro dust and
pollen filter is turned off.

tor goes off. However, automatic mode for
functions other than th at operated is main-
tained.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing 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 immedi-
ately after the automatic mode switch is
pressed or “AUTO” is selected.
Cool air may blow around the upper body
even when the heater is on due to sunlight.
■Automatic mode for air intake control (if
equipped)
In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically 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.
This function automatically controls the
air conditioning airflo w so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver's
seat. Unnecessary air conditioning is
suppressed, contributing to increased
fuel efficiency.
Front seat concentrated airflow mode
operates in the following situations.
 No passengers are detected in the
rear seats
 The windshield defogger is not
operating
 Pollen removal mode is not operat-
ing
