How to Properly Use 4H and 4L?

[OCassidy]

In four-wheel drive vehicles, 4H stands for high-range four-wheel drive, while 4L stands for low-range four-wheel drive. Below is an introduction to the proper use of 4H and 4L: 1. 4H: High-range four-wheel drive is suitable for high-speed driving on paved roads and snowy or wet surfaces, and can also handle most off-road conditions. It significantly improves stability, traction, and handling, but compared to 2H, fuel consumption will increase. N: The neutral position of the transfer case, equivalent to the neutral position of the transmission, serves as a transition and buffer when switching driving modes. Placing it in this gear when towing can prevent damage to components. 2. 4L: Low-range four-wheel drive mode is generally found in vehicles with part-time four-wheel drive systems or those with strong off-road capabilities. In this mode, the four-wheel drive system uses a lower gear ratio to amplify torque. Some models may also automatically lock the central differential, rear differential, and various electronic assistance systems in this mode. 3. 4H is used for quickly passing through uneven terrain, while 4L is used for slowly navigating extreme off-road sections.
