• Ease up on your speed as you approach the top of the hill. Q: What should I do if my vehicle stalls, or is about to stall, and I cannot make it up the hill? • Attach a flag to the vehicle to make you more visible to approaching traffic on trails or hills. A: If this happens, there are some things you should do, and there are some things you must not do. First, here is what you should do: • Sound the horn as you approach the top of the hill to let opposing traffic know you are there. • Use your headlamps even during the day. They make you more visible to oncoming traffic. • Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. • If the engine is still running, shift the transmission {CAUTION: Driving to the top (crest) of a hill at full 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. to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R). • If the engine has stopped running, you will need to restart it. With the brake pedal pressed and the parking brake still applied, shift the transmission to PARK (P) and restart the engine. Then, shift to REVERSE (R), release the parking brake, and slowly back down the hill as straight as possible in REVERSE (R). • As you are backing down the hill, put your left hand on the steering wheel at the 12 o'clock position. This way, you will be able to tell if the wheels are straight and maneuver as you back down. It is best that you back down the hill with the wheels straight rather than in the left or right direction. Turning the wheel too far to the left or right will increase the possibility of a rollover. 4-25
