2004 Cadillac DeVille Owner's Manual - Page 152

When the system comes on, you will see the Night Vision System symbol in the image. After about one minute, you should see the view of the road ahead. If you do not see the image after about two minutes (on cold days it may take longer for the image to display), there may be something wrong with the system. See your dealer for service. {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. {CAUTION: If the Night Vision System image is too bright, or too high in your field of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the image dim and placed low in your field of view. Remember that the Night Vision System can only help you see objects that are warmer or colder than the surroundings. It can not sense things like brake lights, turn signals or emergency flashers, traffic lights or signs. 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. 3-26
