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 “Maintenance Schedule”
in the Index 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.
Supercharger Oil
Unless you are technically
qualified and have the
proper tools, you should
let your dealer or a
qualified service center
perform this maintenance.
When to Check
Check oil level every 30,000 miles (50 000 km) or every
36 months, whichever occurs first.
