yellowblue Comfort Controls This section tells you how to make your air system work for you. Your comfort control system uses ozone-friendly R-134a refrigerant. You can control the heating, cooling and ventilation systems in your vehicle. Guidelines for using these systems are found later in this section. Driver's Side Temperature Knob The driver's side TEMP/AUTO knob adjusts the air temperature coming through the system. Turn the TEMP/AUTO knob clockwise to increase the temperature and counterclockwise to decrease the temperature. Pressing this knob puts the climate control system in an automatic mode. For more information, see "Automatic Operation" later in this section. Passenger's Side Temperature Knob The right front passenger can control the temperature of heated air for their own zone, independent from the driver's temperature setting. The passenger's temperature can be set anywhere between 60_F (16_C) and 90_F (32_C). To turn the system on, press the passenger's side TEMP/OFF knob. Turn the knob clockwise to increase temperature and counterclockwise to decrease. Pressing the knob again turns off the dual-zone function and returns the system to the one-zone function, where the driver controls the temperature. Electronic Climate Control (ECC) Fan Button The button with the fan symbol adjusts the fan speed. Press the up arrow to increase fan speed and the down arrow to decrease fan speed. 3-2
