What is the correct method for continuous downhill driving with an automatic transmission?

Here is the introduction to the correct method for continuous downhill driving with an automatic transmission:1. Drive in a low gear: When driving downhill for a long time, it is essential to use a low gear, just like with a manual transmission. This is because the low gear utilizes the engine's counterforce to help slow down the vehicle. If you rely heavily on the brakes for an extended period, the braking system may overheat, leading to brake fade.2. Press the hill descent control button: Some vehicles are equipped with hill descent control, which can be directly used for downhill driving. Hill descent control usually allows you to select the downhill speed. The specific operation varies by manufacturer, but generally, pressing the function button activates the hill descent control.
When dealing with continuous downhill driving in an automatic transmission car, safety is always my top priority. The key is to utilize engine braking instead of relying solely on the brakes. If the slope is too steep, I switch to a lower gear like L or S mode, allowing the car to decelerate naturally and preventing the brake pads from overheating and failing. Remember to maintain a steady speed—not too fast or too slow—to avoid sudden hard braking that could cause a rollover. Before descending, check the brake fluid and tire pressure to ensure everything is in order. On long descents, I stop at safe spots periodically to let the brakes cool down. Also, keep an eye on the road ahead, slowing down in advance if there are curves. In short, engine braking is the most reliable ally, making the entire downhill journey stable and worry-free, avoiding potential accident risks.
As someone who has driven on mountain roads, I have my own insights: Don't be lazy when going downhill—first shift the gear lever to a lower position, like downshifting to 2nd or 3rd gear in manual mode. Higher engine RPM helps slow the car down, reducing brake usage and wear, making it much safer. I always remind myself not to chase speed; maintaining around 50 km/h is the most stable. If the brakes start smelling burnt or the pedal feels soft, immediately find a flat spot to stop and rest. Also, understand your car's characteristics: for example, SUVs have a higher center of gravity, making them more prone to drifting downhill, so slow down early. I'm used to listening to the engine sound while driving—if the RPM suddenly spikes, it's a reminder to slow down. This way, the car stays in good condition, and I feel more at ease.
