yellowblue Comfort Controls This section tells you how to make your air system work for you. The optional climate control system with air conditioning uses ozone-friendly R-134a refrigerant. With these systems, you can control the ventilation and heating in your vehicle. Your vehicle also has the flow-through ventilation system described later in this section. Fan Knob The left knob selects the force of air you want. Turn the knob clockwise to increase fan speed and counterclockwise to decrease fan speed. To turn the fan off, turn the mode knob all the way counterclockwise to OFF. In any other setting, the fan will run continuously. Temperature Knob The center knob changes the temperature of the air coming through the system. Turn this knob toward red (clockwise) for warmer air. Turn it toward blue (counterclockwise) for cooler air. Mode Knob The right knob has several settings to control the direction of airflow. For each setting, set the temperature to a comfortable setting. VENT: This setting brings in outside air and directs it through the instrument panel outlets. BI-LEVEL: This setting brings in outside air and directs it two ways. Some air is directed through the instrument panel outlets. Most of the air is directed through the floor ducts and a little to the defrost and side window vents. Standard Climate Control System 3-2
