Driving Note: The default setting for the camera delay is off. Press the "Settings" button found on the navigation screen (if equipped) to set the camera delay feature to on or off. When towing, the camera system will only see what is being towed behind the vehicle; this might not provide adequate coverage as it usually provides in normal operation and some objects might not be seen. The camera lens for the camera is located on the liftgate, above the license plate. Keep the lens clean so the video image remains clear and undistorted. Clean the lens with a soft, lint-free cloth and non-abrasive cleaner. Note: If the camera system image is not clear or seems distorted, it may be covered with water droplets, snow, mud or any other substance. If this occurs, clean the camera lens before using the reverse camera system. WARNING: The camera system is a reverse aid supplement device that still requires the driver to use it in conjunction with the rearview mirror and the side mirrors for maximum coverage. WARNING: Objects that are close to either corner of the bumper or under the bumper, might not be seen on the screen due to the limited coverage of the camera system. WARNING: Backup as slow as possible since higher speeds might limit your reaction time to stop the vehicle. WARNING: Do not use the camera system with the liftgate open. If the back end of the vehicle is hit or damaged, then check with your authorized dealer to have your rear video system checked for proper coverage and operation. Night time and dark area use At night time or in dark areas, the reverse camera system relies on the reverse lamp lighting to produce an image. Therefore it is necessary that both reverse lamps are operating in order to get a clear image in the dark. If either of the lamps are not operating, stop using the camera system, at least in the dark, until the lamp(s) are replaced and functioning. 312 2010 Expedition (exd) Owners Guide, 3rd Printing USA (fus)
