Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to outside
air supply and turn on the air
conditioner. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. To turn Auto Defog off or
on, see Climate and Air Quality
under Vehicle Personalization 0 152.
Ionizer : If equipped with an ionizer,
this feature helps to clean the air
inside the vehicle and remove
contaminants; such as pollen, odors,
and dust. If the climate control
system is on and the ionizer is
enabled, the ionizer status indicator
will be lit on the climate control touch
screen. To turn the ionizer on or off,
see Climate and Air Quality under
Vehicle Personalization 0 152.
Rear Window Defogger
: Press to turn the rear window
defogger on or off.
The rear window defogger can be set
to automatic operation. See Climate

Personalization 0 152. When Auto Rear
Defog is selected, the rear window
defogger turns on automatically when
the interior temperature is cold and
the outside temperature is about 4 °C
(40 °F) and below.
The upper grid lines on the rear
window are antenna lines and are not
intended to heat when the defogger is
activated.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and help to
clear fog or frost from the surface of
the mirrors.
