242 UNDERSTANDING YOUR INSTRUMENT PANEL 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, use the A/C button to reduce the humidity inside the vehicle. Fogging on the inside of the windshield can be quickly removed by pressing the defrost button and increasing the blower speed. Do not use the Recirculation mode without the A/C button for long periods as fogging may occur. Outside Air Intake Before driving, always make sure the air intake located directly in front of the windshield is free of obstructions such as leaves, ice, or snow, which could reduce airflow and/or plug the water drain tube inside the plenum.
