308 STARTING AND OPERATING CAUTION! When descending a hill, be very careful to downshift one gear at a time to prevent overspeeding the engine which can cause valve damage. FOUR-WHEEL- DRIVE OPERATION - IF EQUIPPED Four-Wheel-Drive Dodge Ram Trucks are equipped with either a Manually Shifted transfer case or an Electronically Shifted transfer case. See the operating instructions for your transfer case, located within this section. Manually Shifted Transfer Case Operating Information/Precautions The transfer case provides 4 mode positions - 2 (rear)wheel-drive high range, 4-wheel-drive high range, neutral, and 4-wheel-drive low range. This transfer case is intended to be driven in the 2-wheeldrive position (2H) for normal street and highway conditions such as dry hard surfaced roads. When additional traction is required the transfer case 4H and 4L 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 simply moving the shift lever to the desired positions. The 4H and 4L positions are intended for loose, slippery road surfaces only. Driving in the 4H and 4L positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. The 4-wheel-drive light (4WD), located in the instrument cluster, alerts the driver that the vehicle is in 4-wheel drive and that the front and rear driveshafts are locked together. This light illuminates when the transfer case is shifted to either the 4H or 4L positions. There is no light for the 2H or N (Neutral) positions.
