8-8 Climate Controls
@ (Recirculation): Press to
alternate between recirculating air
inside the vehicle or pulling in
outside air. The indicator light on the
button is lit when recirculation mode
is active. This helps to quickly cool
the air inside the vehicle or reduce
the outside air and odors that may
enter.
Pressing this button cancels
automatic recirculation. Press AUTO
to return to automatic operation;
recirculation runs automatically as
needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
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 on
page 5-44.

Defogger): Press to turn the rear
window defogger on or off. An
indicator light on the button comes
on to show that the rear window
defogger is on.
The upper gridlines 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. They help to clear fog
or frost from the surface of the
mirrors.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization on
page 5-44. 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 auto rear
defogger turns off automatically.
