Defogging And Defrosting - Cadillac 1996 DeVille Owner's Manual

The system will go off after a four-minute heating cycle.
If you shift out of PARK (P),
the system will only cycle
for
two
minutes. If
you
want it to cycle again, press the
button. It will go on for two-minute cycles after that. If
the windshield has cleared before the cycle is over, you
can
turn it
off by pressing the button again.
Use the defroster feature
to
clear fog from the
windshield as previously described.
There is a metal film in the windshield which will block
out some radio or microwave signals. Therefore, the
heated windshield will reduce the useful range of
devices such as garage door openers and radar detectors.
(In
certain states, radar detectors
are
legal.)
Do not use the DE-ICE button if your vehicle has a
cracked windshield. A crack will not allow the system to
function properly. Have the windshield repaired before
using the DE-ICE button again.
Defogging and Defrosting
On cool, humid days, use DEFOG to keep the
windshield and side windows clear. Use DEFROST to
remove fog or ice from the windshield quickly in
extremely humid or cold conditions.
Press the DEFOG or DE-ICE button and adjust the fan
speed by pressing the fan button up or down.
If
you use
DEFROST, adjust
the fan speed the same way. If you
select DEFROST from AUTO, the system will control
the fan speed. The temperature will also need to be
adjusted to your comfort level. Press the blue button to
decrease the temperature and the red button to increase
the temperature.
Note that recirculation is not available in the defrost or
defog modes.
