302 STARTING AND OPERATING FOUR-WHEEL DRIVE OPERATION MP1522 Command-Trac Transfer Case - If Equipped Operating Information and Precautions The Command-Trac transfer case provides four positions: • Two-wheel drive (2WD) high range • Four-wheel drive (4WD LOCK) high range • Four-wheel drive (4WD LOW) low range • Neutral (N) This transfer case is intended to be driven in the twowheel drive position (2WD) for normal street and highway conditions such as dry hard-surfaced roads. When additional traction is required, select the transfer case 4WD LOCK position or 4WD LOW position. This 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 this section for specific procedures on shifting into and out of NEUTRAL. 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)
