AIR DUCTS

Air from the heater assembly is distributed around the vehicle interior through distribution ducts to outlets in the instrument panel, the front and rear footwells, and the rear of the cubby box between the front seats.

AIR REGISTERS AND VENTS

In the instrument panel, the air ducts are connected to fixed vents for the windshield and side windows and adjustable registers for face level air. An adjustable register is also installed on the rear of the cubby box for rear face level air. The footwell outlets are fixed vents formed in the end of the related air ducts.

The cabin air filter consists of a serviceable particle filter, or a particle/odor filter, which is installed in the air inlet duct.

The cabin air filter prevents odors and/or particulate matter from entering the vehicle with the fresh air.
