yellowblue Dual ComforTemp Climate Control (If Equipped) Fan Knob The knob on the left side of the climate control panel controls the fan speed. To turn the fan off, turn the knob to OFF. If the airflow seems very low when the fan is adjusted to the highest setting regardless of the mode setting, your passenger compartment air filter may need to be replaced. See "Maintenance Schedule" in the Index. Driver's Temperature Lever The lever on the left adjusts the air temperature on the driver's side independent of the temperature set by the passenger. Slide the lever upward to raise the temperature. Slide the lever downward to lower the temperature. Passenger's Temperature Lever The lever on the right adjusts the air temperature on the passenger's side independent of the temperature set by the driver. Slide the lever upward to raise the temperature. Slide the lever downward to lower the temperature. With this system, you can control the heating, cooling and ventilation in your vehicle. The system works best if you keep your windows closed while using it. 3-4
