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

Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter traps most of the dust and
pollen from the air entering the
vehicle. The filter will need to
be changed periodically. See
Maintenance Replacement Parts on
page 11 9.
Using the climate control system
without the passenger air filter
installed could let water or other
debris enter the system. This could
cause a water leak or noises. Make
sure a new air filter is installed after
removing the old one.
The passenger compartment air
filter is located under the hood
below the windshield wiper arm
and the screen on the passenger
side of the vehicle. See Engine
Compartment Overview on
page 10 6 for more information
on location.
