Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air filter. There are two types of filters
available. There is a standard dust filter that traps small
particles including pollen. There is, also, a dust/odor filter
available that traps dust and pollen and uses a charcoal
element to help reduce many offensive odors from
entering your vehicle. The filter will need to be changed
periodically. For information on when to change the
passenger compartment air filter, see Scheduled
Maintenance on page 6-4.
Notice: Driving without a passenger compartment
air filter in place can cause water and small particles,
like paper and leaves, to be pulled into your climate
control system which may cause damage to it. Make
sure you always replace the old filter with a new one.
The access panel for the passenger compartment air
filter is located under the hood near the windshield, on the
passenger side of the vehicle. See Engine Compartment
Overview on page 5-12 for more information on location.
See Doing Your Own Service Work on page 5-4 for
information on doing your own service work.
To access the passenger compartment air filter:
1. Pull back the rubber hood seal from the edge of the
leaf screen vent cover.
2. Remove the three fasteners that hold the filter
cover in place and slide the cover off.
3. To access the filter, remove the water deflector by
lifting the outboard edge of the deflector to release
the retention tab.
