Cadillac 2008 DTS Automobile User Manual


 
There is also an interior
temperature sensor
located next to the steering
wheel that measures the
temperature of the air
inside your 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 10 mph (16 km/h)
for 5 minutes.
Vehicle speed is above 32 mph (51 km/h)
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.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to clear
fog from your windshield. Use the floor/defog mode
to clear the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.
W (Floor/Defog): Turn the control to this mode to
direct approximately half of the air to the floor outlets
and the remaining air is directed to the side window
outlets and to the windshield. When you select
this mode, the system turns off recirculation and runs
the air conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the floor/defog mode.
