Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTO
button on the touchscreen on the Automatic Temperature
Control (ATC) Panel.
2. Next, adjust the temperature you would like the system
to maintain by adjusting the driver and passenger
temperature control buttons. Once the desired tempera -
ture is displayed, the system will achieve and automati -
cally maintain that comfort level.
3. When the system is set up for your comfort level, it is not
necessary to change the settings. You will experience the
greatest efficiency by simply allowing the system to func -
tion automatically.
NOTE:
• It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts the
temperature, mode, and blower speed to provide comfort
as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable
feature. Refer to the “Uconnect Settings” in “Multimedia”
for further information.
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 blower will increase in
speed and transition into Auto mode.
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.
