UNDERSTANDING YOUR INSTRUMENT PANEL 203 Winter Operation Use of the air Recirculation mode during winter months is not recommended because it may cause window fogging. NOTE: See Operating Tips chart (for Manual A/C Control) at the end of this section for suggested control settings in different weather conditions. 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 Interior fogging on the windshield can be quickly removed by turning the mode selector to Defrost. The Defrost/Floor mode can be used to maintain a clear windshield and provide sufficient heating. If side window fogging becomes a problem increase blower speed. Vehicle windows tend to fog on the inside in mild but rainy or humid weather. NOTE: Recirculate without A/C should not be used 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. A/C Air Filter - If Equipped The climate control system filters outside air containing dust, pollen and some odors. Strong odors cannot be totally filtered out. Refer to "Maintenance Procedures" in your Owner's Manual for filter replacement instructions. 4
