UNDERSTANDING YOUR INSTRUMENT PANEL 295 glycol antifreeze coolant in water is recommended. Refer to section 7, Maintenance Procedures, of this manual for proper coolant selection. Winter Operation To insure the best possible heater and defroster performance, make sure the engine cooling system is functioning properly and the proper amount, type, and concentration of coolant is used. Refer to section 7, Maintenance Procedures, of this manual for proper coolant selection. Use of the air Recirculation mode during winter months is not recommended because it may cause window fogging. Vacation Storage Anytime you store your vehicle, or keep it out of service (i.e. vacation) for two weeks or more, run the air conditioning system at idle for about five minutes in the fresh air and high blower setting. This will insure adequate system lubrication to minimize the possibility of compressor damage when the system is started again. Window Fogging Vehicle windows tend to fog on the inside in mild rainy or humid weather. To clear the windows, select defrost or mix mode and increase the front blower speed. Do not use the Recirculation mode without A/C for long periods as fogging may occur. Outside Air Intake Make sure the air intake, located directly in front of the windshield, is free of obstructions such as leaves. Leaves collected in the air intake may reduce airflow and if they enter the plenum they could plug the water drains. In winter months make sure the air intake is clear of ice, slush and snow. 4
