286 STARTING AND OPERATING NOTE: The transfer case NEUTRAL position is to be used for recreational towing only. Refer to "Recreational Towing" in this section for specific procedures on shifting into and out of NEUTRAL. Transfer Case Position Indicator Lights Transfer case position indicator lights are located on the instrument cluster. If there are no indicator lights on or flashing, the transfer case position is four-wheel drive (4WD) and indicates the current and desired transfer case selection (4WD ⇔ 4WD LOCK). The "SVC 4WD Warning Light" monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required. See your authorized dealer for service. WARNING! Always engage the parking brake when powering down the vehicle if the ؆SVC 4WD Warning Light" is illuminated. Not engaging the parking brake may allow the vehicle to roll, which may cause personal injury. NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning. The NV 244 Generation II transfer case is not equipped with a synchronizer and therefore the front and rear driveshaft speeds must be equal for the shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case.
