UNDERSTANDING YOUR INSTRUMENT PANEL 177 Mix Outside air comes from the floor and defrost outlets. This mode works best in cold or snowy conditions. It allows you to stay comfortable while keeping the windshield clear. Defrost Outside air comes from the windshield outlets with a small amount being directed through the floor outlets. Use this setting when necessary to defrost your windshield. NOTE: For improved safety, the A/C compressor is activated when "Mix" or "Defrost" modes are selected. This is done to assist in drying the air and it will help in keeping the windshield from fogging. Operating Tips Summer Operation The engine cooling system in air conditioned vehicles must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. A 50% solution of ethylene glycol antifreeze coolant in water is recommended. Winter Operation The air from the heater system will heat faster in cold weather if you use lower blower speeds until the engine warms up. 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. 4
