For the Gen III, is the Cabin Filter the same as an A/C filter? The Maintenance Manual gives inspection and change intervals for the Cabin Filter. Yet the Owner's Manual does discuss or show the location of a Cabin Filter. They list the A/C Filter, the Engine Filter and the Pollen and Dust Filter. The A/C Filter is shown as located behind the Glove Compartment. Is this the same as what the Maintenance Manual describes as the Cabin Filter?
