200 STARTING AND OPERATING An advantage of the higher ground clearance is a better view of the road, allowing you to anticipate problems. They are not designed for cornering at the same speeds as conventional 2-wheel drive vehicles any more than lowslung sports cars are designed to perform satisfactorily in off-road conditions. If at all possible, avoid sharp turns or abrupt maneuvers. As with other vehicles of this type, failure to operate this vehicle correctly may result in loss of control or vehicle rollover. OFF-ROAD DRIVING TIPS When To Use 4 LO (Low) Range When off-road driving, shift to 4 LO for additional traction in moving forward or descending a hill, for low-speed pulling power or to improve handling and control on slippery or difficult terrain. Also use 4 LO range on the road in rain, ice, snow, mud or sand to get heavy loads rolling, or whenever "High" range fourwheel drive traction is insufficient. In Snow, Mud and Sand In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4 LO if necessary. Don't shift to a lower gear than necessary to maintain headway. Over-revving the engine can spin the wheels and traction will be lost. Do not downshift on icy or slippery roads, because engine braking may cause skidding and loss of control. Hill Climbing Before climbing a steep hill, shift the transmission to a lower gear and shift the transfer case to 4 LO. Use first gear and 4 LO for very steep hills. If you stall or begin to lose headway while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine and shift to R (Reverse). Back slowly down the hill allowing the compression braking of the engine and transmission
