AUTO-LOCK FREE-RUNNING HUBS mud or deep snow. The 4L position provides maximum power and traction. Avoid raising vehicle speed excessively, as the maximum speed in 5th gear is approximately 30 MPH (48 km/h). N - No wheels are driven. Always keep the transfer lever out of the N (Neutral) position. Shift the lever quickly and smoothly when moving across the N (Neutral) position with the vehicle stopped. Your NISSAN is equipped with one of two 4WD systems, auto-lock free-running hubs or manual-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. SD0021 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. If your vehicle is equipped with this system, follow these operational cautions: CAUTION ● The auto-locking hubs will make a clicking noise when engaging and disengaging. This is normal. 5-16 Starting and driving
