Cadillac XLR-V 2006 Owner's Manual page 155

If the outside temperature goes up, the display
temperature will not change until:
•
The vehicle's speed is above 10 mph (16 km/h)
for five minutes.
•
The vehicle's speed is above 32 mph (51 km/h)
for two and one-half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition button. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
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 or frost
from your windshield. Use the floor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly.
-
(Floor/Defog): Press the mode button until the
defog mode appears on the display. This mode directs
the air between the windshield, floor outlets and
side windows. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is near or
below freezing. The recirculation mode cannot be
selected while in the floor/defog mode.
1
(Defrost): Press this button to direct most of the
air to the windshield, with some air directed to the side
windows. In this mode, the system will automatically
turn off the recirculation and run the air-conditioning
compressor, unless the outside temperature is near or
below freezing. Recirculation cannot be selected while in
the defrost mode. Do not drive the vehicle until all the
windows are clear.
