Comfort Controls Temperature Knob Turn the center knob to change the temperature of the air flowing from the system. Turn it toward the red (clockwise) for warmer air and toward the blue (counterclockwise) for cooler air. Mode Knob OFF: In this setting the system is off. MAX (Maximum): This setting provides maximum cooling or quick cool-down on very hot days. It recirculates most of the air inside your vehicle. If it is used for long periods of time the air may become dry. This setting directs air through the upper air vents. A/C (Air Conditioning): Use A/C for normal cooling on hot days. This setting cools outside air and directs it through the upper air vents. The air conditioner compressor operates in MAX, A/C, bi-level, blend and defrost when the outside temperature is above freezing. When the air conditioner is on, you may sometimes notice slight changes in your vehicle's engine speed and power due to the operation of the compressor. With this system, you can control the heating, air conditioning and ventilation in your vehicle. Your vehicle also has the flow-through ventilation system described later in this section. Fan Knob Use the knob on the left of the control panel to select the force of air you want. Turn the knob clockwise to increase fan speed and counterclockwise to decrease fan speed. 3-2
