AUTO-LOCK FREE-RUNNING HUBS Accelerating quickly from a stop after shifting from two-wheel drive to four-wheel drive may not allow engagement of the auto-locking freerunning hubs and may cause a clattering noise. Continued use of the vehicle with this noise may damage the hub lock. In such a case, release the accelerator pedal to reduce the engine speed or stop the vehicle. If the auto-locking hubs make a clattering noise after shifting from fourwheel drive to two-wheel drive, stop and move the vehicle about 7 to 10 feet (2 to 3 m) in reverse. Under extremely cold conditions [below 5°F (-15°C)], the front axle shafts may rotate even with the transfer lever in the 2H position. If this occurs, the auto-locking hubs may make a clattering noise. To avoid this, drive first in four-wheel drive to warm up the vehicle and differential gear oil. Then, shift to two-wheel drive. In cold weather, it may be necessary to reduce speed or stop the vehicle in order to shift from two-wheel drive to four-wheel drive. When shifting into or out of fourwheel drive while driving, do not stop shift lever movement midway. An incomplete shift may cause a clattering noise from the autolocking hubs. Continued use of the vehicle with this noise may damage the hub lock. Drive in four-wheel drive to stop the noise. Shift to twowheel drive as described. SD0021 Your NISSAN is equipped with auto-lock free-running hubs. The auto-lock free-running hub is designed to allow for automatic four-wheel drive engagement when the shift lever is moved to the 4H or 4L position. Follow these operational cautions: CAUTION The auto-locking hubs will make a clicking noise when engaging and disengaging. This is normal. 5-20 Starting and driving
