Rear Air Outlets The outlet behind the left rear seat is the cold air return outlet. Be sure to keep it free from obstructions. Also, keep the area around the base of the center instrument panel console, between and under the front seats, free of objects that could also obstruct airflow to the rear seating area. For more information on how to use the main climate control system, see Dual Climate Control System on page 220. For information on ventilation, see Outlet Adjustment on page 223. The access panel for the passenger compartment air filter is located in the back of the glove box. To replace the filter, do the following: Passenger Compartment Air Filter Passenger compartment air, both outside and recirculated air, is routed through a passenger compartment filter. The filter removes most particles from the air, including dust particles. Reductions in airflow, which may occur more quickly in dusty areas, indicate that the filter needs to be replaced early. For how often to change the air filter, see Scheduled Maintenance on page 539. 1. Pull the tab located on the outer access panel up and out. 228
