Recirculation is not available in the defrost mode
and shuts off when defog mode is selected.
Both of these features are designed to limit fogging
in the vehicle. If recirculation is selected during
defog mode, it automatically turns off after
10 minutes to limit problems with fogging.
In some conditions, using recirculation for long
periods of time can cause the air inside the vehicle
to become too dry or stuffy. To prevent this from
happening, after the air in the vehicle has
cooled, select AUTO to return to automatic climate
control operation or push the recirculation button
again to select outside air.
Press this button a second time to select
outside air.
:(Outside Air): This mode forces the system
to pull air from outside the vehicle. It can be
used to bring fresh air into the vehicle.
Air Quality Sensor: Your vehicle could have an
air quality sensor to help limit the climate
control system from pulling in some harmful
exhaust fumes from older, poorly running, or
diesel-equipped vehicles that are driving near you.
This sensor, when active, monitors the air
quality in front of your vehicle and switches to air
recirculation when poor quality air is detected
outside your vehicle. Press the AUTO button on
the climate control to activate the air quality
sensor. The word AUTO comes on the center of
the climate control display. While the air quality
sensor senses poor quality air, the recirculation
graphic displays.
Under some conditions, the air quality sensor
system does not operate. In cold weather, the
system might not be active (even if AUTO is
displayed) because of concerns of fogging your
windows, which may occur by activating
recirculation mode. Also, the air quality sensor
system does not remain in recirculation mode for
extended periods of time that could cause stuffy or
very dry conditions in the vehicle. Following a
poorly running vehicle for an extended period of
time may not keep recirculation active indefinitely.
