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 0149.
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

ACCESSORY.
The rear window defogger can be set
to automatic operation. See “Climate

Personalization 0149. 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 7 °C
(45 °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 mirrors turn on
when the rear window defogger
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
with a razor blade or anything else
that is sharp. This may damage the
rear window defogger grid and
affect the radio's ability to pick up
stations clearly. The repairs would
not be covered by the vehicle
warranty.
