Driving You should either know the terrain or examine maps of the area before driving. Map out your route before driving in the area. For more information on driving off-road, read the "Four Wheeling" supplement in your owner's portfolio. If your vehicle gets stuck If the vehicle is stuck, shift the transmission in a steady motion between forward and reverse gears. Allow the transmission to engage, then press lightly on the accelerator. Do not rock the vehicle for more than a few minutes. The transmission and tires may be damaged or the engine can overheat. Do not spin the wheels at over 56 km/h (35 mph). The tires may fail and injure a passenger or bystander. Sand When driving over sand, try to keep all four wheels on the most solid area of the trail. Do not reduce the tire pressures but shift to a lower gear and drive steadily through the terrain. Apply the accelerator slowly and avoid spinning the wheels. Mud and water If you must drive through high water, drive slowly. Traction or brake capability may be limited. When driving through water, determine the depth; avoid water higher than the bottom of the hubs (if possible) and proceed slowly. If the ignition system gets wet, the vehicle may stall. Once through water, always try the brakes. Wet brakes do not stop the vehicle as effectively as dry brakes. Drying can be improved by moving your vehicle slowly while applying light pressure on the brake pedal. After driving through mud, clean off residue stuck to rotating driveshafts and tires. Excess mud stuck on tires and rotating driveshafts causes an imbalance that could damage drive components. If the transmission and transfer case are submerged in water, their fluids should be checked and changed, if necessary. Water intrusion into the transmission may damage the transmission. 104
