yellowblue A/C: Press this button to turn the air conditioning on and off. The system will cool and dehumidify the air inside the vehicle. The indicator light will come on to show that A/C is active. The air conditioning compressor will only come on when the system needs it. Fan Knob The center knob is the fan knob and controls the force of air you want. Turn the knob clockwise to increase fan speed and counterclockwise to decrease fan speed. The fan will always run unless the mode knob is turned to OFF. Temperature Knob The right knob regulates the temperature of the air coming through the system. Turn it toward the blue area for cooler air. Turn it toward the red area for warmer air. Air Conditioning On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down and also reduces the time the air conditioner's compressor will have to run, which should help fuel economy. Then keep your windows closed for the air conditioner to work its best. For a quick cool-down on very hot days, use the RECIRC setting. Press the A/C button, and if the A/C indicator light is not on, press the A/C button a second time to turn it on. Then, turn the fan knob to its highest speed. If this setting is used for long periods of time, the air in your vehicle may become too cold and dry. For normal cooling on hot days, select the UPPER mode. To do this, press the A/C button. If the A/C indicator light does not turn on, turn the temperature knob to the blue area and select the appropriate fan speed. This setting cools the air entering your vehicle and directs it through the upper outlets. The direction of the cool air can be controlled by adjusting or turning off the instrument panel outlets. 3-3
