Cadillac 2005 DeVille Owner's Manual page 141

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:
{
Do not use the Night Vision System to replace
your normal view of the road ahead. It can not
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 do not 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 to
clean the HUD or camera lens. Wipe gently and
dry thoroughly.
Notice: When cleaning, be careful not to scratch
the HUD or camera lenses. Do not spray glass
cleaner directly on the HUD lens 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.
