STARTING AND OPERATING 285 NV 244 Generation II Transfer Case Operating Information/Precautions - If Equipped The NV 244 Generation II is an electric-shift transfer case and is operated by the 4WD Control Switch, which is located on the instrument panel. The NV 244 Generation II transfer case provides four mode positions - Normal four-wheel drive (4WD) high range, four-wheel drive lock (4WD LOCK) range, fourwheel drive low (4WD LOW) range, and NEUTRAL. This transfer case is equipped with an inter-axle differential that allows driving the vehicle in the normal all-wheel drive position (4WD) at all times on any given road surface, including dry, hard-surfaced roads. The 4WD mode allows the front and rear wheels to rotate at different speeds. This eliminates driveline binding and component wear normally associated with driving the vehicle in the 4WD LOCK position on dry, hard-surfaced roads. This feature provides the safety, security, and convenience of operating in all-wheel drive at all times regardless of road conditions. When additional traction is required, the 4WD LOCK and 4WD LOW positions can be used to lock the front and rear driveshafts together, through the transfer case inter-axle differential, and force the front and rear wheels to rotate at the same speed. This is accomplished by rotating the 4WD Control Switch to these positions. The 4WD LOCK and 4WD LOW positions are intended for loose, slippery road surfaces only. Driving in the 4WD LOCK and 4WD LOW positions on dry, hard-surfaced roads may cause increased tire wear and damage to the driveline components. The transfer case NEUTRAL position is selected by depressing the recessed button located on the lower left hand corner of the 4WD Control Switch. 5
