Which gear should be used when descending a steep slope?

Descending a steep slope requires the use of the L gear. Here is an introduction to the L gear: 1. Low gear: The L gear in a car stands for L-Low. When going downhill or descending a long slope, shifting into this gear restricts the car's automatic transmission to the lowest gear (equivalent to first gear in a manual transmission car). This allows the car to use engine braking when descending, preventing the driver from having to apply the brakes continuously, which could lead to overheating of the brake pads and potential hazards. 2. Braking function: In this gear, the transmission remains in first gear without shifting up, which can be useful on slopes. It also provides some braking effect when descending hills.
I often drive on downhill mountain roads, and the experience is to always use a lower gear. For manual transmissions, choose 1st or 2nd gear; for automatic transmissions, shift to L or S mode, mainly relying on engine braking to reduce brake wear. Relying solely on brakes for steep descents can easily lead to overheating and failure, which is very dangerous. Once, my brakes were smoking when going downhill, which scared me, so I’ve since developed the habit of downshifting. Also, check tire pressure and brake system conditions to avoid accidents. Pay more attention to your car’s condition during long drives—safety is the top priority.
From a car repair perspective, not downshifting when descending steep slopes accelerates brake wear. I've seen too many cases of warped brake discs or overheating failures due to high-speed downhill driving in high gears. For manual transmissions, I recommend using 1st gear; for automatics, use M mode or low gear mode to maintain engine braking. Keep your speed within safe limits and avoid excessive brake pedal pressure. During regular maintenance, pay extra attention to brake fluid and cooling systems to extend component lifespan. This simple and effective driving technique can save you unnecessary repair costs.
