Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment filter, which is part of a three piece filter
system. The filter removes certain particles from the air,
including pollen and dust particles. Reductions in
airflow, which may occur more quickly in dusty areas,
indicate that the filter needs to be replaced early.
The particle filter is located inside of the air control
module. The air control module is located behind
an access panel near the accelerator pedal.
The filter should be replaced as part of routine
scheduled maintenance. See Part A: Scheduled
Maintenance Services on page 6-4 for replacement
intervals. See your dealer for details on changing
the filter.
Once you remove your filter, if you choose not to replace
it, it will not damage your vehicle. However, the air will
no longer be filtered.
