Passenger Compartment Air Filter
Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment filter. The filter removes most particles
from the air, including dust particles. 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 on page 6-4.
The access panel for the passenger compartment air
filter is located in the back of the glove box. To replace
the filter, do the following:
1. Pull the tab located on the outer access panel up
and out.
