Cadillac 2008 STS-V Automobile User Manual


 
Sensors
There is a solar sensor located on the instrument panel,
near the windshield.
There is also an interior temperature sensor located
next to the steering wheel on the instrument panel.
These sensors monitor the solar radiation and the air
inside the vehicle, then use the information to adjust
the temperature, the fan speed and the air delivery
system, 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.
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 the windshield. Use the 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.
yN z(Mode): Press this button until defog appears
on the display.
-(Defog): This mode directs the air between the
windshield and floor outlets with some air supplied to
the outboard panel outlets and side window defogging
outlets. When this mode is selected, the system turns off
recirculation and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode is cancelled when the system
enters the defog mode. If recirculation is selected while
in the defog mode, it is cancelled after 10 minutes.
