Climate Control Influence on Fuel Economy
The climate control system depends on other vehicle systems for heat and power input. Certain climate control settings can lead to higher fuel usage.
The following climate control settings use more fuel:
- MAX air conditioning mode
- Defrost mode
- Extreme temperature settings, such as 15° C (60° F) or 32° C (90° F)
- High fan speed settings To help reduce fuel usage:
- Use the full automatic control as described under “Automatic Operation.”
- Select a temperature setting that is higher in hot weather and lower in cold weather.
- Turn off the air conditioning when it is not needed.
- Only use defrost to clear the windows.
To place the system in automatic mode:
- Press AUTO.
- Set the driver and passenger temperature. To find your comfort setting, start with 22 °C (72 °F) and allow the system time to stabilize. Then adjust the temperature as needed for the best comfort.
To improve fuel efficiency and to cool the vehicle faster, recirculation may be automatically selected in warm weather. The recirculation light will not come on when automatically controlled. Press @to manually select recirculation; press it again to select outside air. Do not cover the solar sensor on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load. See “Sensors” later in this section.
ON/OFF: Press to turn the climate control system on or off. When the system is off, outside air will be prevented from entering the vehicle. When the system is on, a button is pressed, or the knob is turned, the climate control system will turn on and deliver airflow per the current setting. Q 9 R: Press the fan controls on the center stack or the climate control display to increase or decrease the fan speed. Press and hold the controls to adjust speed more quickly.
Press AUTO to return to automatic operation.
Driver and Passenger Temperature Control:
The temperature can be adjusted separately for the driver and the passenger. Press w / x to increase or decrease the temperature. SYNC: Press to link the passenger and rear climate temperature settings, if equipped, to the driver setting. The SYNC indicator light will turn on. When the passenger or rear climate temperature settings are adjusted, the SYNC indicator light is off. The driver-side or passenger-side temperature display shows the temperature setting increasing or decreasing.
Air Delivery Mode Control:
Press Y,[, or z to change the direction of the airflow. An indicator light comes on in the selected mode button. All three buttons or any combination of the three buttons can be used to select the air delivery mode. Changing the mode cancels the automatic operation and the system goes into manual mode. Press AUTO to return to automatic operation.
z: This mode clears the windows of fog or moisture. Air is directed to the windshield, outboard panel outlets, and side window vents. The system automatically forces outside air into the vehicle and the air conditioning compressor will run, unless the outside temperature is close to freezing.
Y: Air is directed to the instrument panel outlets. Air is directed to the floor outlets, with some to the windshield, side window outlets, outboard panel outlets, and second-row floor outlets.
0: Press to clear the windshield of fog or frost more quickly. Air is directed to the windshield, outboard panel outlets, and side window outlets. The air conditioning compressor also comes on, unless the outside temperature is below freezing. Do not drive the vehicle until all windows are clear. See Air Vents 0 185.
A/C: Press to turn the air conditioning system on or off. An indicator light comes on to show that the air conditioning is enabled. If the fan is turned off, the air conditioner will not run. The A/C light will stay on even if the outside temperatures are below freezing.
@: Press to turn on the recirculation. An indicator light comes on. Air is recirculated to quickly cool the inside of the vehicle. It can also be used to help reduce outside air and odors that enter the vehicle. The air conditioning compressor also comes on when this mode is activated.
Ionizer: If equipped with an ionizer, this feature helps to clean the air inside the vehicle and remove contaminants such as pollen, odors, and dust. If the climate control system is on and the ionizer is enabled, the ionizer status indicator will be lit on the climate control display. To turn the Ionizer off or on, select Settings > Climate and Air Quality > Ionizer > Select ON or OFF.
Rear Window Defogger
The rear window defogger uses a warming grid to remove fog from the rear window. K : 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 can be turned off by turning the vehicle off or to accessory mode.
Using a razor blade or sharp object to clear the inside rear window can damage the rear window defogger. Repairs would not be covered by the vehicle warranty. Do not clear the inside rear window with sharp objects.
If equipped with heated outside mirrors, the mirrors heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. See Heated Mirrors 0 26.
Remote Start Climate Control Operation :
If equipped with remote start, the climate control system may run when the vehicle is started remotely. The rear defog may come on during remote start based on cold. ambient conditions. The rear defogs 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.
The solar sensor, located in the defrost grille in the middle of the instrument panel, monitors the solar heat. Do not cover the solar sensor or the system will not work properly. There is also an exterior temperature sensor behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false reading in the displayed temperature.
The climate control system uses the information from these sensors to maintain comfort settings by adjusting the outlet temperature, fan speed, and air delivery mode. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures.
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.
Adjustable air vents are in the center and on the sides of the instrument panel, and on the rear of the center console storage. Move the slider knobs to change the direction of or to close off the airflow.
- Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the flow of air into the vehicle.
- Clear snow off the hood to improve visibility and help decrease moisture drawn into the vehicle.
- Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively.
- The use of non-GM-approved hood deflectors can adversely affect the performance of the system. Check with your dealer before adding equipment to the outside of the vehicle.
- Do not attach any devices to the air vent slats. This restricts airflow and may cause damage to the air vents.
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 0 366. See your dealer regarding the replacement of the filter.
All vehicles have a label under the hood 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. 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 0 366.
