Driving Nighttime 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 reverse camera system, at least in the dark, until the lamp(s) are replaced and functioning. Servicing • If the vehicle is in R (Reverse) and the screen in the rear view mirror appears blue for three seconds and turns blank afterwards, the camera is not working properly; have the system inspected by your authorized dealer. • If the image comes on while the vehicle is not in R (Reverse), have the system inspected by your authorized dealer. • If the vehicle is in R (Reverse) and the screen is blank and no blue screen is observed, the mirror is not working properly; have the system inspected by your authorized dealer. • If the image is not clear, then check if there is anything covering the lens such as dirt, mud, ice, snow, etc. If the image is still not clear after cleaning, have your system inspected by your authorized dealer. FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED) For important information regarding safe operation of this type of vehicle, see Preparing to drive your vehicle in this chapter. When four-wheel drive (4WD) is engaged, power is supplied to all four wheels through a transfer case. 4WD can be selected when additional traction is desired. 4WD operation is not recommended on dry pavement. Doing so could result in difficult disengagement of the transfer case, increased tire wear and decreased fuel economy. 276 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
