Cadillac 2010 DTS - Manual (Page 207)

There is also an interior
temperature sensor
located next to the
steering wheel that
measures the temperature
of the air inside the
vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false reading in the displayed temperature.
In order to prevent false temperature readings at
startup, the displayed temperature will not change
until the following occurs:
. Vehicle speed is above 16 km/h (10 mph) for
5 minutes.
. Vehicle speed is above 51 km/h (32 mph) for
2 and a half minutes.
The climate control system uses the information
from these sensors to maintain your comfort setting
by adjusting the outlet temperature, fan speed, and
the air delivery mode. The system may also supply
cooler air to the side of the vehicle facing the sun.
The recirculation mode will also be used as needed
to maintain cool outlet temperatures.
Outlet Adjustment
For the front outlets, use the thumbwheel located below
each outlet to change the direction of the airflow. Use
the thumbwheel located next to the outlets to shut the
airflow or to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up or
down to change the direction of the airflow.
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.
