Passenger Compartment Air Filter
Outside air is routed through a passenger compartment
air filter before entering the vehicle. This filter removes
certain particles from the air, including pollen and dust
particles. The filter should be replaced as part of routine
scheduled maintenance. See Scheduled Maintenance
on page 7‑3 for when to replace the filter.
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. Press the tabs back and left to remove the cover.
2. Insert a tool behind the push pin located on the
inboard side of the air filter compartment to
carefully pry the pin out.
