Passenger Compartment Air Filter - Cadillac STS 2011 Owner's Manual

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 7 3.
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.
