Driving Night time and dark area use At night time or in dark areas, the 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. Servicing • If the image comes on while the vehicle is not in R (Reverse), 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) WARNING: 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 driving power 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. Manual Shift On Stop (MSOS) 4x4 system (if equipped) The 4WD system is engaged or disengaged by rotating the control for both front wheel hub locks from the FREE or LOCK position, then manually engaging or disengaging the transfer case with the floor-mounted shifter. For increased fuel economy in 2WD, rotate both hub locks to the FREE position. 284 2010 F-250/350/450/550 (f23) Owners Guide, 2nd Printing USA (fus)
