Passenger Compartment Air Filter - Cadillac CTS 2015 Owner's Manual

Move the slider knobs (2) to change
the direction of the airflow.
Additional air vents are beneath the
windshield and the driver and
passenger side door windows.
These are fixed and cannot be
adjusted.
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 before
adding equipment to the outside
of the vehicle.
Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.

Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.

replacement of the filter.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
