Temperature Control: Use the driver's and passenger's levers to increase or decrease the air temperature inside your vehicle. Turn the right knob clockwise or counterclockwise to direct the airflow inside of your vehicle. To change the current mode, select one of the following: 6 (Floor): This mode directs most of the air to the floor outlets. Use this mode to send air to the rear of the vehicle. Keep the area under the front seats free of objects that could obstruct airflow to the rear of the vehicle. Outside Air: This mode is automatically selected when your vehicle is in any mode except maximum air conditioning. The right knob can also be used to select defog or defrost mode. For more information, see "Defogging and Defrosting" later in this section. @ MAX A/C (Maximum Air Conditioning): Turn the right knob to this position for maximum air conditioning. This will select air conditioning and recirculation for maximum cooling of your vehicle. Recirculation: This mode keeps outside air from coming in the vehicle. It can be used to prevent outside air and odors from entering your vehicle or help heat or cool the air inside your vehicle more quickly. This mode will automatically be selected when maximum air conditioning is selected. # (Air Conditioning): Press this button to turn the air conditioning system on or off. When it is pressed, an indicator light in the button will come on to let you know that air conditioning is activated. You may notice a slight change in engine performance when the air conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature. On hot days, open the windows to let hot inside air escape; then close them and switch to maximum air conditioning mode. This helps to reduce the time it takes for your vehicle to cool down. It also helps the system to operate more efficiently. H (Vent): This mode directs air to the instrument panel outlets. ) (Bi-Level): This mode directs half of the air to the instrument panel outlets, then directs the remaining air to the floor outlets. Cooler air is directed to the upper outlets and warmer air to the floor outlets. 3-28
