Rear Automatic Temperature Control (ATC)

The rear ATC system has floor air outlets at the rear right side of the 3rd Row seats and overhead outlets at each outboard rear seating position. The system provides heated air through the floor outlets or cool, dehumidified air through the headliner outlets.

The rear system temperature control buttons are located in the Uconnect system, located on the instrument panel

Rear ATC Control Features

1 - Blower Speed
2 - Rear Temperature
3 - Rear Mode
4 - Rear Temperature Lock
5 - AUTO Mode

• Press the Rear Temperature Lock button on the Uconnect touchscreen. This turns off the Rear Temperature Lock icon in the rear temperature knob.
•  Rotate the Rear Blower, Rear Temperature and the Rear Mode Control knobs to suit your comfort needs.
•  ATC is selected by adjusting the rear blower knob counterclockwise to AUTO.

Once the desired temperature is displayed, the ATC System will automatically achieve and maintain that comfort level. 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. The system automatically adjusts the temperature, mode and fan speed to provide comfort as quickly as possible.

Rear Blower Control

The rear blower control, located in the rear overhead console, has an off position and a range of blower speeds.

This allows the second row seat occupants to control the volume of air circulated in the rear of the vehicle.

Rear Temperature Control

To change the temperature in the rear of the vehicle, rotate the temperature control knob counterclockwise for cold air, and clockwise for heated air.

Rear Mode Control

•  Auto Mode The rear system automatically maintains the correct mode and comfort level desired by the rear seat occupants.
•  Headliner Mode Air comes from the outlets in the headliner. Each of these outlets can be individually adjusted to direct the flow of air. Moving the air vanes of the outlets to one side will shut off the airflow.
•  Bi-Level Mode Air comes from both the headliner outlets and the floor outlets.NOTE: In many temperature positions, the BI-LEVEL mode is designed to provide cooler air out of the headliner outlets and warmer air from the floor outlets.
•  Floor Mode Air comes from the floor outlets.

Operating Tips

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.

A solution of 50% OAT (Organic Additive Technology) coolant that meets the requirements of FCA Material Standard MS.90032 and 50% water is recommended.

Refer to "Maintenance Procedures" in "Maintaining Your Vehicle" for proper coolant selection.

Winter Operation

Use of the air Recirculation mode during winter months is not recommended because it may cause window fogging.

Vacation Storage

Any time you store your vehicle or keep it out of service (i.e., vacation) for two weeks or more, run the air conditioning system at idle for about five minutes in the fresh air and high blower setting. This will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again.

Window Fogging

Interior fogging on the windshield can be quickly removed by turning the mode selector to Defrost. The Defrost/Floor mode can be used to maintain a clear windshield and provide sufficient heating. If side window fogging becomes a problem increase blower speed.

Vehicle windows tend to fog on the inside in mild but rainy or humid weather.

NOTE: Recirculate without A/C should not be used for long periods, as fogging may occur.

Outside Air Intake

Make sure the air intake, located directly in front of the windshield, is free of obstructions such as leaves. Leaves collected in the air intake may reduce airflow, and if they enter the plenum, they could plug the water drains. In winter months, make sure the air intake is clear of ice, slush, and snow.

A/C Air Filter

The climate control system filters outside air containing dust, pollen and some odors. Strong odors cannot be totally filtered out. Refer to "Maintenance Procedures" in "Maintaining Your Vehicle" for filter replacement instructions.
