Cadillac 2009 Automobile User Manual


 
Sensors
The solar sensor located on the instrument panel, near
the windshield, monitors the solar heat.
The interior temperature sensor located on the
instrument panel to the right of the steering wheel,
measures the temperature of the air inside the vehicle.
The climate control system uses the information
from these sensors to adjust the temperature, the fan
speed and the air delivery, in order to maintain the
selected temperature. The system may also supply
cooler air to the side of the vehicle facing the sun.
Do not cover the sensors or the automatic climate
control system will not work properly.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airflow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airflow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards
the center console to close the outlets and minimize
the amount of air entering the vehicle.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment air
filter may need to be replaced. For more information,
see Passenger Compartment Air Filter on page 3-54.
