9-8 Driving and Operating When driving on hills: . Use a low gear and keep a firm grip on the steering wheel. Maintain a slow speed. When possible, drive straight up or down the hill. Slow down when approaching the top of the hill. Use headlamps even during the day to make the vehicle more visible. { WARNING Driving to the top of a hill at high speed can cause an accident. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert. . { WARNING If the vehicle has the two‐speed automatic transfer case, shifting the transfer case to N (Neutral) can cause your vehicle to roll even if the transmission is in P (Park) for an automatic transmission or any gear position for a manual transmission. This is because the N (Neutral) position on the transfer case overrides the transmission. You or someone else could be injured. If leaving the vehicle, set the parking brake and shift the transmission to P (Park) for an automatic transmission or any gear position for a manual transmission. Shift the transfer case to any position but N (Neutral). . . . . Never go downhill forward or backward with either the transmission or transfer case in N (Neutral). The brakes could overheat and you could lose control.
