■Windshield wiper de-icer (if equipped)
This feature is used to prevent ice from
building up on the wi ndshield and wiper
blades.
The windshield de-icer will automatically
turn off after approximately 15 minutes.
■Eco air conditioning mode
When Eco drive mode is selected using the
driving mode select switch, eco air condi-
tioning mode turns on.
When a drive mode other than Eco drive
mode is selected, eco air conditioning
mode may turn off.
■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 approximately 1 to 3 minutes.
In order to prevent the windshield from fog-
ging up when the outside air is cold, the

the outside/recirculat ed air mode may not
switch to (recirculated air) mode.
Pollen is filtered even if the micro dust and
pollen filter is turned off.

■Using automatic mode
Fan speed is adjusted automatically accord-
ing to the temperature setting and the

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.
■Windshield fog detection function
When automatic mode is set, the humidity
sensor detects fog on the windshield and
controls the air condit ioning system to pre-
vent fog.
■Automatic mode for air intake control
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.

shield wiper de-icer)
