Recirculation
When outside air contains smoke, odors, or high humidity,
or if rapid cooling is desired, you may wish to recirculate
interior air by pressing the Recirculation control button.
The Recirculation indicator will illuminate when this but-
ton is selected. Press the button a second time to turn off
the Recirculation mode and allow outside air into the
vehicle.
NOTE: In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation fea-
ture may be unavailable (button on the touchscreen greyed
out) if conditions exist that could create fogging on the
inside of the windshield. On systems with Manual Climate
Controls, the Recirculation mode is not allowed in Defrost
mode to improve window clearing operation. Recirculation
will be disabled automatically if this mode is selected.
Attempting to use Recirculation while in this mode will
cause the LED in the control button to blink and then turn
off.
Automatic Temperature Control (ATC) If
Equipped
Automatic Operation
1. Push the AUTO button on the front ATC panel and the
word “AUTO” will illuminate in the front ATC display,
along with two temperatures for the driver and front
passenger. The system will then automatically regulate
the amount of airflow.
2. Adjust the temperature you would like the system to
maintain, by adjusting the driver, and passenger tem-
peratures. Once the desired temperature is displayed,
the system will achieve and automatically maintain that
comfort level.
