Outlet Adjustment; Passenger Compartment Air Filter - Cadillac 2009 CTS Owner's Manual

Outlet Adjustment

Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow. Use the
thumbwheels near the air outlets to open or close off
the airflow.
Operation Tips
•
Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
flow of air into the vehicle.
•
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
•
Use of non-GM approved hood deflectors can
adversely affect the performance of the system.
Check with your dealer/retailer before adding
equipment to the outside of the vehicle.

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 Scheduled Maintenance on page 6-4.
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 5-14
for more information on location.
