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. Four-wheel drive (4WD) supplies power to all four wheels. 4WD should not be operated on dry pavement; driveline damage may occur. If equipped with the Electronic Shift 4WD System, and 4WD Low is selected while the vehicle is moving above 3 mph (5 km/h), the 4WD system will not engage past 4WD High. This is normal and should be no reason for concern. Refer to Shifting to/from 4L (4WD Low) for proper operation. System indicator lights • 4X4 HI - Momentarily illuminates when the engine is started.
