Here is the correct way to use an automatic transmission car: 1.P——Parking gear. When the car is parked and not in use, the gear is in this position, at which time the wheels are mechanically locked to prevent rolling. 2.R——Reverse gear. Used when reversing. 3.N——Neutral gear. Used when temporarily stopping (e.g., at a red light). 4.D——Drive gear, also known as the driving gear. Used when moving forward. 5.L——Low gear. Used when going downhill. 6.OD, Overdrive gear, used when driving at high speeds.
