FOUR-WHEEL DRIVE OPERATION NV 144 Transfer Case Operating Information/Precautions The NV 144 is an electric shift transfer case and is operated by the Four-Wheel-Drive (4WD) Control Switch, which is located on the instrument panel. The NV 144 transfer case provides 2 mode positions: All-Wheel Drive (AWD) and 4-Wheel-Drive LOCK. The NV 144 transfer case is designed to be driven in for AWD for normal street and highway conditions (all road surfaces roads). When additional traction is required, the transfer case 4LOCK position can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by rotating the 4WD Control Switch to the 4LOCK position - see Shifting Procedure section for specific shifting instructions. The 4LOCK position is designed for loose, slippery road surfaces only. Driving in the 4LOCK position on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. Transfer Case Position Indicator Lights Transfer case position indicator lights are located on the instrument cluster, and indicate the current and desired transfer case selection. If there are no indicator lights on or flashing the transfer case position is All-Wheel Drive (AWD). The "SVC 4WD" warning light monitors the electric shift 4WD system.
