UNDERSTANDING YOUR INSTRUMENT PANEL 219 Circulation Control Use this button to choose between outside air intake or recirculation of the air inside the vehicle. A lamp will illuminate when you are in recirculate mode. Only use the recirculate mode to temporarily block out any outside odors, smoke, or dust and to cool the interior rapidly upon initial start up in very hot or humid weather. NOTE: Continuous use of the recirculate mode may make the inside air stuffy and window fogging may occur. Extended use of this mode is not recommended. In cold or damp weather, the use of the Recirculate position will cause windows to fog on the inside because of moisture build up inside the vehicle. For maximum defogging, select the Outside Air position. NOTE: Recirculation Mode will not operate in floor, mix or defrost modes. Air Filtration System - If Equipped An air filter is included in the optional Security Group. Filter media includes a particle filtration layer and a charcoal layer. The filter will reduce, but not eliminate, diesel and agricultural smells. The filter acts only on air coming from outside the vehicle; it does not filter air inside the passenger compartment. See the maintenance schedule for the filter change interval. The air filter change interval coincides with engine oil and filter change intervals. As with oil changes, the interval is shorter for heavy duty service or dusty conditions. See your authorized dealer for service. 4
