Climate Control Status Display
The climate control status display appears briefly when the center stack climate controls are adjusted.
Automatic Operation
The system automatically controls the fan speed, air delivery, air conditioning, and recirculation in order to heat or cool the vehicle to the desired temperature.
When AUTO is lit, all four functions operate automatically. Each function can also be manually set and the selected setting is displayed. Functions not manually set will continue to be automatically controlled, even if the AUTO indicator is not lit.
For automatic operation:
- Press AUTO.
- Set the temperature. Allow the system time to stabilize. Adjust the temperature as needed for best comfort.
To improve fuel efficiency and to cool the vehicle faster with A/C on, recirculation may be automatically selected in warm weather. Press @ to select recirculation; press it again to select outside air.
Driver and Passenger Temperature Controls : The temperature can be adjusted separately for the driver and the passenger. Turn the knob clockwise or counterclockwise to increase or decrease the driver or passenger temperature setting.
SYNC : Press to link all passenger temperature settings to the driver setting.
The SYNC indicator light will turn on. When the passenger settings are adjusted, the SYNC indicator light turns off.
Manual Operation
Press to turn the fan off or on. When off is selected, the system will prevent air from flowing into the cabin. If on is selected, or any other button is pressed, the climate control system will turn on and return to delivering airflow as set. The temperature control and air delivery mode can still be adjusted.
Press to increase or decrease the fan speed. The fan speed setting appears on the main display. Pressing any airflow mode button cancels automatic fan control and the fan is controlled manually. Press AUTO to return to automatic operation.
Air Delivery Mode Controls : Press X, Y, or[to change the direction of the airflow. Any combination of the three buttons can be selected. The indicator light in the button will turn on. The current mode appears in the display. Pressing either button cancels automatic air delivery control and the direction of the airflow is controlled manually. Press AUTO to return to automatic operation.
To change the current mode, select one or more of the following modes:
Clears the windows of fog or moisture.
Air is directed to the windshield.
Air is directed to the instrument panel outlets.
Air is directed to the floor outlets.
MAX : Air is directed to the windshield, the fan runs at a higher speed, and the temperature of the air is increased if not already at maximum. This mode overrides the previous mode selected and clears fog or frost from the windshield more quickly. When the button is pressed again, the system returns to the previous mode setting and fan speed. For best results, clear all snow and ice from the windshield before defrosting and do not use recirculation.
A/C : Press to turn the air conditioning system on or off. If the climate control system is turned off or the outside temperature falls below freezing, the air conditioner will not run. Pressing this button cancels automatic air conditioning and turns off the air conditioner. Press AUTO to return to automatic operation and the air conditioner runs automatically as needed. When the indicator light is on, the air conditioner runs automatically to cool the air inside the vehicle or to dry the air needed to defog the windshield faster.
Press to turn on recirculation. An indicator light comes on. Air is recirculated to quickly cool the inside of the vehicle or to reduce the entry of outside air and odors. If selected during cool or cold weather, the windshield and windows may fog. Turn off recirculation to help clear the windshield and windows.
Auto Defog : The climate control system may have a sensor to automatically detect high humidity inside the vehicle. When high humidity is detected, the climate control system may adjust to outside air supply and turn on the air conditioner. The fan speed may slightly increase to help prevent fogging. If the climate control system does not detect possible window fogging, it returns to normal operation. To turn Auto Defog off or on, select Settings > Climate and Air Quality > Auto Defog > Select ON or OFF.
Rear Window Defogger
Press to turn the rear window defogger on or off. An indicator light on the button comes on to show that the rear window defogger is on. The rear window defogger only works when the vehicle is on. The defogger turns off when the vehicle is off or in accessory mode.
The rear window defogger can be set to automatic operation. To turn Auto Defog off or on, select Settings > Climate and Air Quality > Auto Rear Defog > Select ON or OFF. When Auto Rear Defog is selected, the rear window defogger turns on automatically when the interior temperature is cold and the outside temperature is about 7 °C (44 °F) and below. The auto rear defogger turns off automatically.
If the vehicle is equipped with heater outside mirrors, they turn on when the rear window defogger button is on and help to clear fog or frost from the surface of the mirror. See Heated Mirrors 0 27.
Caution
Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect the radio’s ability to pick up stations clearly. The repairs would not be covered by the vehicle warranty.

Remote Start Climate Control Operation :
If equipped with remote start, the climate control system may run when the vehicle is started remotely. The system will use the defrost setting if it is cold outside or turn on using the coldest settings if it is hot outside. The rear defog may come on during remote start based on cold ambient conditions. The rear defog indicator light does not come on during a remote start.
If equipped, the heated seats will turn on if it is cold outside or the ventilated seats will turn on if it is hot outside. The heated and ventilated seat indicator lights may not come on during a remote start. If equipped, the heated steering wheel will come on in a remote start if it is cold outside. The heated steering wheel indicator light may not come on. See Remote Vehicle Start 0 14 and Heated and Ventilated Front Seats 0 41.
Sensor
The solar sensor, on top of the instrument panel near the windshield, monitors the solar heat. The climate control system uses the sensor information to adjust the temperature, fan speed, recirculation, and air delivery mode for the best comfort. Do not cover the sensor; otherwise, the automatic climate control system may not work properly.
After blow Feature
If equipped, under certain conditions, the fan may stay on or may turn on and off several times after you turn off and lock the vehicle. This is normal.
Air Vents
Use the air outlets in the center and on the side of the instrument panel to direct the airflow. Turn the center knobs on the air
outlets counterclockwise or clockwise to open or close off the airflow.
Operation Tips
- Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that can block the flow of air into the vehicle.
- Clear snow off the hood to improve visibility and help decrease moisture drawn into the vehicle.
- The use of non-GM-approved hood deflectors can adversely affect the performance of the system.
- Keep the path under all seats clear of objects to help circulate the air inside the vehicle more effectively.
- If fogging reoccurs while in the vent or in a combination mode with mild temperature throughout the vehicle, turn on the air conditioner to reduce windshield fogging.
Maintenance
Passenger Compartment Air Filter The filter reduces dust, pollen, and other airborne irritants from outside air that is pulled into the vehicle. The filter should be replaced as part of routine scheduled maintenance. See Maintenance Schedule 0 317. See your dealer regarding the replacement of the filter.
Service
All vehicles have a label under hold that identifies the refrigerant used in the vehicle. The refrigerant system should only be serviced by trained and certified technicians. The air conditioning evaporator should never be repaired or replaced by one from a salvage vehicle. It should only be replaced by a new evaporator to ensure proper and safe operation. During service, all refrigerants should be reclaimed with proper equipment. Venting refrigerants directly to the atmosphere is harmful to the environment and may also create unsafe conditions based on inhalation, combustion, frostbite, or other health-based concerns.
The air conditioning system requires periodic maintenance. See Maintenance Schedule 0 317.
