DRIVER (Driver's Side Temperature): The lever on the left adjusts the air temperature for the driver's side outlets. Slide the lever up to raise the temperature and down to lower the temperature. For normal cooling on hot days, use VENT with the temperature levers in the blue area. The system will bring in outside air and cool it. On cool, but sunny days, the sun may warm your upper body, but your lower body may not be warm enough. Select BI-LEV and set the temperature levers to a comfortable setting. The system will bring in outside air and direct it to your upper body, while sending slightly warmed air to your lower body. Push the A/C button for cooling. PASSENGER (Passenger's Side Temperature): The lever on the right adjusts the air temperature for the passenger's side outlets. Slide the lever up to raise the temperature and down to lower the temperature. Press this button to turn the air-conditioning on and off. An indicator light above the button will come on when the air conditioning is on. During daylight hours you may need to adjust the interior lighting control to the highest setting in order to see the light. The system will cool and dehumidify the air inside the vehicle when the A/C indicator light is on. On very hot days, open the windows long enough to let hot, inside air escape. This reduces the time for the vehicle to cool down. For a quick cool-down on a very hot day, use MAX with the temperature levers all the way in the blue area. If this setting is used for long periods of time, the air in your vehicle may become too dry. @ (Air Conditioning): Defogging and Defrosting DEF (Defrost): This setting, located on the right knob, directs most of the air through the defroster and the side window outlets. Some of the air is directed to the floor and side window outlets. The air-conditioning compressor will run automatically in this setting unless the outside temperature is below 40°F (4°C). To defrost the window quickly, turn the mode knob to the defrost setting and turn the driver's and passenger's temperature levers all the way to the red area. To warm passengers while keeping the windows clear, use BLEND. 3-20
