NOTICE:
If the air cleaner/filter is off, a backfire can
cause a damaging engine fire. And, dirt can
easily get into your engine, which will damage
it. Always have the air cleaner/filter in place
when you're driving.
Passenger Compartment Air Filter
Replacement (If Equipped)
Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment filter, which is part of a two
system. The filter removes certain contaminants from
the air, including pollen and dust particles, as well as
odors such as exhaust or fuel fumes. Reductions in
airflow, which may occur more quickly in dusty areas,
indicate that the filter needs to be replaced early. For
how often to change the air filter, see "Scheduled
Maintenance" in the Index.
The access panel for the passenger compartment
air filter is located in the back of the glove box.
