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. . . 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. . . { 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). 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). Shift the transfer case to any position but N (Neutral). When driving down a hill, keep the vehicle headed straight down. Use a low gear because the engine will work with the brakes to slow the vehicle and help keep the vehicle under control. { WARNING Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and you or others could be injured or killed. Apply the brakes lightly when descending a hill and use a low gear to keep vehicle speed under control. If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking brake. 2. Shift into P (Park) and then restart the engine. . { 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.
