may need to be changed periodically. For how often to
change the passenger compartment air filter, see
Scheduled Maintenance on page 7-3.
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:
1. Use a tool to remove the cover. If the vehicle has
tabs that allow the cover to be unlatched with your
fingers, a tool will not be needed for this step.
