Passenger Compartment Air Filter
The passenger compartment
air filter is located
underneath your hood just
below the windshield wiper
arm on the passenger side
(underneath the air inlet
grille) of the vehicle.
The filter traps most of the pollen from the air entering
the air conditioning module. Like your engine’s air
cleaner filter, it may need to be changed periodically.
For information on how often to change the passenger

the Index.
