What gear is generally used for automatic transmission cars when going down a long slope?

Automatic transmission cars generally use L gear, manual mode, S gear, or D gear when going down a long slope. An automatic transmission car refers to a vehicle that does not require the driver to manually shift gears, as the vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. The gears of an automatic transmission car include: 1. P gear is the parking gear; 2. R gear is the reverse gear; 3. N gear is the neutral gear; 4. D gear is the drive gear; 5. M gear refers to the manual mode; 6. L gear is the low gear; 7. S gear is the sport mode. The precautions for going downhill are: 1. Do not coast in neutral when going downhill; 2. During the downhill process, steer the wheel gently; 3. Before going downhill, test whether the braking performance is good.
After driving for so many years, especially during mountain trips, it's best to switch an automatic transmission car to a lower gear when going down a long slope, such as the L gear or low-speed gear in manual mode. This allows the engine to help you slow down, avoiding brake fade or failure from prolonged braking. I remember once going down a mountain road in D gear the whole time, and the brakes ended up smoking. Since then, I've learned my lesson: slow down before entering the slope and select the right gear to maintain a steady speed. When operating, choose the appropriate gear based on the slope gradient and speed—don't wait until you lose control to react. Safety-wise, this habit prevents problems before they occur, protecting the braking system and extending the vehicle's lifespan. It's also a good idea to practice manual mode regularly to get familiar with the car's response, making driving more relaxed.
During daily commutes when encountering long downhill slopes, I wouldn't hesitate to shift to a lower gear, such as switching to 2nd gear or L gear. This method is simple yet effective - the engine automatically slows down to keep the vehicle stable, preventing brake overheating issues. The principle is to utilize the engine's braking force to control speed, saving you from exhausting constant brake pedal use. For weekend outings, I always check gear options first to ensure safe operation. Never overlook details when driving - maintaining steady speed on long slopes is crucial. If your vehicle has hill descent control, activate it; otherwise, manual downshifting works just as well. Remember, safety comes first. Avoid frequent acceleration and braking, as this accelerates brake pad wear, leading to troublesome and costly repairs.
