Passenger Compartment Air Filter
The passenger compartment air filter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/filter, it may need to
be changed periodically. For how often to change the
passenger compartment air filter, see Scheduled
Maintenance on page 6-4.
The access panel for the passenger compartment air
filter is located under the hood near the windshield,
on the passenger’s side of the vehicle.
To access the passenger compartment air filter, do the
following:
1. Use a tool to gently pry the cover up. (If your vehicle
has tabs that allow you to unlatch the cover with your
fingers, you will not need a tool for this step.)
