button is turned off.
The rear ATC is located on the rear of the front
center console.
Press the Rear Temperature Lock button on
the front Uconnect touchscreen a second

Push a rear blower button, adjust the
temperature using the rear up and down
arrows, and select a control mode to suit the
rear occupant’s needs.

Once the desired temperature is shown on the

experience the greatest efficiency by simply
allowing the system to function automatically.

Automatic Operation

system to maintain, by adjusting the driver,
passenger, and rear temperatures. Once
the desired temperature is displayed, the

level, it is not necessary to change the
settings. You will experience the greatest

comfort as quickly as possible.
To provide you with maximum comfort in the
automatic mode, during cold start-ups, the
blower fan will remain on low until the engine
warms up. The fan will engage immediately if
the Defrost mode is selected, or by changing the
front blower knob setting.
Manual Operation Override
This system offers a full complement of manual
override features. The AUTO symbol in the front
ATC display will be turned off when the system
is being used in the manual mode.
NOTE:
The system will not automatically sense the
presence of fog, mist or ice on the windshield.
Defrost mode must be manually selected to
clear the windshield and side glass.
