• Sound the horn as you approach the top of the hill to let opposing traffic know you are there. There are some things you should do if the vehicle stalls, or is about to stall, and you cannot make it up the hill: • Use your headlamps even during the day.

REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R). • If your engine has stopped running, you will need to restart it. With the brake pedal pressed, apply the parking brake. If you have an automatic transmission, shift the transmission to PARK (P). Restart the engine.

This way, you will be able to tell if your wheels are straight and maneuver as you back down. It is best that you back down the hill with your 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. 4-24
