When to Use the L Gear in a Car?

When to use the L gear in a car: 1. Use it when starting from a stop; 2. Use it when encountering pedestrians, vehicles, or obstacles; 3. Use it when driving through severe waterlogged sections or climbing steep slopes. The working principle of a manual transmission car is to switch the driving gear on the intermediate shaft by moving the gear lever, combining with the power output shaft through different gear sizes to change the torque and speed of the driving wheels. The method of shifting gears in a manual transmission car: 1. Depress the clutch and release the accelerator: Depressing the clutch and accelerator simultaneously prevents the engine speed from rising rapidly; 2. Maintain the correct shifting posture: Due to the synchronizer's function, the two gears to be meshed will not contact or produce gear impact before their speeds are synchronized. Once synchronized, the two gears will mesh smoothly without causing impact damage; 3. Accelerate after releasing the clutch: To avoid impact force, releasing the clutch is crucial. When depressing the clutch and shifting the transmission lever into a new gear, a certain speed will be achieved only after synchronization by the synchronizer.
As a seasoned driver with years of experience, I always switch to L gear when going down steep slopes to control the speed. Relying solely on brakes can easily lead to overheating and failure, while L gear allows the engine to assist in deceleration, making it much safer. I remember one trip to the mountainous area with winding roads—I insisted on using L gear all the way down, and the brakes didn’t overheat at all. I also use L gear when towing uphill, like when hauling camping gear up a slope—the car starts more steadily and avoids slipping. In congested urban areas, I occasionally use L gear to maintain low speeds, crawling at under 20 km/h in stop-and-go traffic, which also saves some fuel and protects the transmission. Overall, L gear isn’t used every day, but in critical situations like long slopes or slippery roads, it’s like a thoughtful assistant, making driving more relaxed.
