2. A/C (Air Conditioning)
3. Air Delivery Mode Controls
4. Fan Control
5. Defrost
6. Passenger Temperature Control
7. SYNC (Synchronized Temperature)
8. Rear Window Defogger
9. Power Button
10. Air Recirculation
11. AUTO (Automatic Operation)

Automatic Operation

The system automatically controls the following four functions to heat or cool the vehicle to the desired temperature:

• Fan Speed
• Air Delivery Mode
• Air Conditioning
• Recirculation

When the AUTO indicator light is lit, all four functions are operating automatically. Each function can be manually set and the selected setting will be shown. This cancels full automatic operation and the AUTO indicator light turns off. Functions that are not manually set will continue to be automatically controlled, although the AUTO indicator light will not be lit.

To place the system in automatic mode:

1. Press AUTO.
2. 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 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 “Sensor” later in this section.

Manual Operation

: Press to turn the climate control system on or off. When off, no air will flow into the vehicle. Turning the fan on, pressing any other button, or turning a knob will turn the system back on.

: Turn clockwise or counterclockwise to increase or decrease the fan speed. Press the knob to turn the fan off.

Press AUTO to return to automatic operation.

Driver and Passenger Temperature Control : The temperature can be adjusted separately for the driver and passenger.

Turn the knob clockwise or counterclockwise to increase or decrease the driver or passenger temperature setting.

SYNC : Press to link the passenger temperature settings to the driver setting. The SYNC indicator light will turn on. When the passenger 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 , , , or to change the direction of the airflow. An indicator light comes on in the selected mode button.

Changing the mode cancels the automatic operation and the system goes into manual mode. Press AUTO to return to automatic operation.

: Air is directed to the instrument panel outlets.

: Air is divided between the instrument panel and floor outlets.

: Air is directed to the floor outlets, with some to the windshield, side window outlets, and second row floor outlets.

: This mode clears the windows of fog or moisture. Air is directed to the windshield, floor outlets, and side window vents.

: Press to clear the windshield of fog or frost more quickly. Air is directed to the windshield and the side window vents. 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.

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 and the A/C compressor may be off.

: Press to turn on 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.

Rear Window Defogger

The rear window defogger uses a warming grid to remove fog from the rear window.

- : 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 ignition is on. The defogger turns off if the ignition is turned off or to ACC/ACCESSORY.

Caution

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.

Heated Mirror : 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.

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 best comfort. The automatic recirculation mode sensitivity can be adjusted. See “Air Quality Sensor” under Vehicle Personalization.

Do not cover the sensor; otherwise the automatic climate control system may not work properly.
