recirculated to quickly cool the

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. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation.

temperature is about 7 °C (44 °F)
and below. The auto rear defogger
turns off automatically.
If the vehicle is equipped with
heated outside mirrors, they turn on
when the rear window defogger
button is on and help to clear fog or
frost from the surface of the mirror.
