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 0170.
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

defogger turns on automatically when
the interior temperature is cold and
the outside temperature is about 4 °C

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 mirrors turn on

button is on and help to clear fog or
frost from the surface of the mirrors.
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
