STARTING AND OPERATING 221 Electronically Shifted Transfer Case Operating Information/Precautions This is an electric shift transfer case and is operated by the 4WD Control Switch (Transfer Case Switch), which is located on the instrument panel. The Electronically Shifted transfer case provides 4 mode positions: 2 (rear) wheel drive high range or all wheel drive high range, 4 wheel drive high range, 4 wheel drive low range, and neutral. The Electronically Shifted transfer case is designed to be driven in the 2 wheel drive position (2WD) or all wheel drive position (AWD) for normal street and highway conditions (dry hard surfaced roads). When additional traction is required, the transfer case 4HI and 4LO positions 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 desired position - see Shifting Procedure section for specific shifting instructions. The 4HI and 4LO positions are designed for loose, slippery road surfaces only. Driving in the 4HI and 4LO positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. NOTE: The transfer case Neutral (N) position is selected by depressing the recessed button located on the lower left hand corner of the 4WD Control Switch. The transfer case Neutral (N) position is to be used for recreational towing only. See the Recreational Towing section for specific procedures on shifting into and out of Neutral (N). 5
