316 STARTING AND OPERATING position locks the front driveshaft and rear driveshaft together and forces the front and rear wheels to rotate at the same speed. Use the transfer case NEUTRAL position for recreational towing only. Refer to "Recreational Towing" in "Starting and Operating" for further information. CAUTION! (Continued) • The 4WD LOCK position and 4WD LOW position are intended for loose or slippery road surfaces only. Driving in these positions on dry hardsurfaced roads may cause increased tire wear and damage to the driveline components. • When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD position or 4WD LOCK position at a given road speed. Take care not to over-speed the engine and do not exceed 25 mph (40 km/h). • Proper operation of four-wheel drive vehicles depends on tires of equal size, type, and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Tire rotation schedule should be followed to balance tire wear. CAUTION! • Do not attempt to make a shift while only the front wheels or rear wheels are spinning. The MP1522 Command-Trac transfer case is not equipped with a synchronizer and therefore the speed of the front driveshaft and rear driveshaft must be equal for the shift to take place. Shifting while only the front wheels or rear wheels are spinning can cause damage to the transfer case. (Continued)
