Auto Defog : The climate control

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 0 150.
Ionizer : If equipped with an ionizer,
this feature helps to clean the air

odors, and dust. If the climate
