9-14 Driving and Operating Things not to do when driving down a hill: . If you decide you can go down a hill safely, try to keep the vehicle headed straight down. Use a low gear so engine drag can help the brakes so they do not have to do all the work. Descend slowly, keeping the vehicle under control at all times. Driving Across an Incline An off-road trail will probably go across the incline of a hill. To decide whether to try to drive across the incline, consider the following: When driving downhill, avoid turns that take you across the incline of the hill. A hill that is not too steep to drive down might be too steep to drive across. The vehicle could roll over. Never go downhill with the transmission in N (Neutral), called free-wheeling. The brakes will have to do all the work and could overheat and fade. { WARNING Driving across an incline that is too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, do not drive across it. Find another route instead. . { WARNING Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and a serious accident. Apply the brakes lightly when descending a hill and use a low gear to keep vehicle speed under control. . Vehicles are much more likely to stall when going uphill, but if it happens when going downhill: 1. Stop the vehicle by applying the regular brakes and apply the parking brake. 2. Shift to P (Park) and, while still braking, restart the engine. 3. Shift back to a low gear, release the parking brake, and drive straight down. 4. If the engine will not start, get out and get help. A hill that can be driven straight up or down might be too steep to drive across. When going straight up or down a hill, the length of the wheel base - the distance from the front wheels to the rear wheels - reduces the likelihood the vehicle will tumble
