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 temperature is displayed, the 

system will achieve and automatically 

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 

function 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 U.S./Metric 

customer-programmable feature within the 

Uconnect system  

Ú

page 186.

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 

Automatic Temperature Control (ATC) display will 

be turned off when the system is being used in the 

manual mode.

Adjust vehicle temperatures hands-free and keep 

everyone comfortable while you keep moving

beep, say one of the following commands:

“Set driver temperature to 70 degrees”

Did you know: Voice Command for Climate may 

only be used to adjust the interior temperature of 

your vehicle. Voice Command will not work to 

adjust the heated seats or steering wheel if 

equipped.

NOTE:

Refer to the chart at the end of this section for 

suggested control settings for various weather 

conditions.

Summer Operation

The engine cooling system must be protected with 

a high-quality antifreeze coolant to provide proper 

corrosion protection and to protect against engine 

overheating. OAT coolant (conforming to 

MS.90032) is recommended  

Ú

page 366.

Winter Operation

To ensure the best possible heater and defroster 

performance, make sure the engine cooling 

system is functioning properly and the proper 

amount, type, and concentration of coolant is 

used. Use of the Air Recirculation mode during 

Winter months is not recommended, because it 

may cause window fogging.

Vacation/Storage  

For information on maintaining the Climate Control 

system when the vehicle is being stored for an 

extended period of time, see
