UNDERSTANDING YOUR INSTRUMENT PANEL 203 Window Fogging In mild but rainy or humid weather, windows will fog on the inside. To rapidly clear the fog off all the windows, select the defrost mode, turn the temperature control knob fully clockwise, and position the blower control to its highest speed. Once the windshield has been cleared, adjust the controls for your comfort. On air conditioned vehicles, the compressor will operate when in the Mix or Defrost modes and when the outside temperature is approximately 30°F (-1°C) to provide additional defrost/defog. Summer Operation Air conditioned vehicles must be protected with a high quality anti-freeze coolant during summer to provide proper corrosion protection and to raise the boiling point of the coolant for protection against overheating. A 50% concentration is recommended. Winter Operation When operating the system during the winter months, make sure the air intake, located directly in front of the windshield, is free of ice, slush, snow, or other obstructions. REAR WINDOW FEATURES Rear Window Wiper/Washer A rotary ring switch on the control lever, located on the right side of the steering column, controls operation of the rear wiper/washer function. Rotating the center of the switch up to the DEL (Delay) position or the ON position will activate the wiper. Rotating the switch ring beyond the ON or OFF position will activate the rear washer. The wash pump will continue to operate as long as the lever or ring is engaged. Upon release, the wipers will cycle three times before returning to the set position. 4
