What are the gears of a fully automatic car?

The gears of a fully automatic car are R, N, D, and L. Below are the meanings of the automatic transmission gears R, N, D, and L: 1. R stands for Reverse gear, which can only be engaged when the vehicle is stationary. For models with a lock button, the button must also be pressed to switch. 2. N stands for Neutral gear, used for temporary parking to stop the vehicle's movement without interrupting the power. For example, when waiting at a traffic light, the handbrake should also be engaged. This gear is prohibited when going downhill. 3. D stands for Drive gear, the most commonly used gear. Gear shifting is controlled by the accelerator pedal. D1 (or L gear), D2, and D3 correspond to manual transmission gears 1 and 2, 3 and 4, and 5 and 6, respectively. 4. L stands for Low gear, used when going downhill to reduce brake usage, or when going uphill to provide more power for climbing.
Driving a fully automatic car is actually quite simple when it comes to gear shifting. After years of driving, I find the D gear the most convenient for all situations. For daily driving, just shift to D gear and the car will handle the gear changes automatically, eliminating the need to constantly press the accelerator and clutch in traffic jams. When reversing, make sure to press the brake before shifting to R gear to avoid jerking. The N gear is rarely used; I only shift to it during red lights longer than 30 seconds to give the transmission a break. Always engage the P gear before turning off the engine to prevent the locking mechanism from jamming. Some cars also have an S gear for climbing hills or overtaking, or an L gear for controlling speed on long descents. Remember to always start the car in P gear—safety first.
The design of automatic transmission gears is to lower the driving threshold. The P (Park) gear is a mechanical locking structure to ensure the vehicle is completely stationary. When using the R (Reverse) gear, pay attention to the surrounding environment. The N (Neutral) gear disconnects the engine power connection and can be used for short stops. The D (Drive) gear is the universal forward gear, where the vehicle shifts automatically based on throttle depth. During my test drive, I found some cars come with a manual mode, where paddle shifters behind the steering wheel allow temporary intervention for upshifting or downshifting, adding to the fun of control. Different brands have varying gear lever positions, such as column shift or rotary dial, but the functions are largely similar.
