What is the correct usage of the L gear?
2 Answers
When going uphill, shift to L gear for stronger climbing ability, and when going downhill, shift to L gear to control speed. The following are the correct methods for using the L gear: 1. 'L' stands for 'low,' meaning it is the low-speed gear. Generally, L gear is only available in low to mid-range automatic transmission models because these models' automatic transmissions do not have a manual mode. The L gear can be used when climbing or descending steep slopes. After shifting into L gear, the transmission will only switch between 1st and 2nd gears, and no matter how hard you press the accelerator, it will not shift to 3rd gear or higher. When the car is in low gear, the wheel torque increases, making it more conducive to climbing. 2. When descending a slope, shifting into low gear can utilize engine braking to slow the car down.
As a veteran driver with 20 years of experience, I think the correct use of L gear is simple yet crucial. When you encounter a steep slope that needs to be climbed, especially when towing heavy loads or driving in snow, shifting to L gear keeps the engine at low speed but high torque, providing more traction and preventing the car from rolling backward. It's even more practical when descending steep slopes, as it allows engine braking to slow you down gradually without constantly pressing the brakes, avoiding overheating and brake failure. Remember to use it only at low speeds, such as below 20 to 30 kilometers per hour, and never switch to L gear on highways, as excessively high engine RPMs can damage internal components. Normally, just keep the car in D (Drive) mode for fuel efficiency and convenience. For example, last year during a mountain road trip, I used L gear and smoothly navigated both uphill and downhill sections, enhancing driving safety. This technique protects your car and extends mechanical lifespan—the key is developing the habit of using it only in appropriate situations.
