Cadillac 2000 DeVille Owner's Manual page 174

In dry, clear weather, the system can see pedestrians,
animals and the direction of the road ahead. In light rain,
light snow or light fog the image may not be as clear
and you may not be able to see the direction of the road
ahead. In more severe weather conditions, the image
may be unclear and not usable.
CAUTION:
Don't use the Night Vision System to replace
your normal view of the road ahead. It can't tell
you how far away things are. It senses only
warmer or colder objects, not all objects. Driving
by staring at the image might cause you not to see
important objects in the road ahead. If you don't
see something in time, you could have a crash in
which you and others could be injured. Use the
Night Vision System only as a driving aid.
It is also important to keep your windshield, the HUD
(Head-Up Display for the Night Vision System) lens and
the camera lens clean. If you do not keep everything
clean, system performance may be affected. The HUD
system is located on the driver's side of the instrument
panel, next to the windshield and the camera is located
behind the center of the front grille.
Use only household glass cleaner and a soft cloth. Wipe
gently and dry thoroughly.
NOTICE:
Be careful not to scratch the HUD or camera
lenses when cleaning. Use only household glass
cleaner and a soft cloth. Wipe gently and dry
thoroughly. Also, do not spray glass cleaner
directly on the HUD lens located inside your
vehicle, because the cleaner could leak inside the
unit and cause damage.
The camera must also be aligned to work correctly. If
the camera needs adjustment, see your dealer. Do not
attempt to adjust the camera yourself.
