Air Vents; Passenger Compartment Air Filter - Cadillac CTS 2013 Owner's Manual

8-6 Climate Controls

Air Vents

Use the air outlets in the centre 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 windscreen 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 bonnet
air flow deflectors can adversely
affect the performance of the
system. Check with your dealer
before adding equipment to the
outside of the vehicle.
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 should be
replaced as part of routine
scheduled maintenance; see
Scheduled Maintenance on
page 11 1. To find out what type of
filter to use, see Maintenance
Replacement Parts on page 11 7.
Using the climate control system
without the passenger air filter
installed could let water or other
debris into 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 bonnet
below the windscreen wiper arm
and the screen on the passenger
side of the vehicle.
To replace the passenger
compartment air filter:
1. Put the ignition in the ON/RUN
position with the engine off.
2. Turn on the windscreen wipers
and turn the ignition off again
when the wipers are straight up
on the windscreen.
This allows access to the leaf
screen. The passenger
compartment air filter is located
under the screen.
