What does h4l mean?

H4L means - High-speed four-wheel drive mode, with the central differential locked and the front and rear axles rigidly connected, suitable for low-adhesion road surfaces such as rain, snow, and gravel roads. Below is relevant information: Four-wheel drive: Four-wheel drive refers to a form where the vehicle maintains four-wheel drive throughout the entire driving process, with the engine's output torque distributed to the front and rear wheels in a fixed proportion. This drive mode can provide good off-road and handling performance at any time, but it cannot adjust torque distribution according to road conditions, and it has higher fuel consumption. Four-wheel system: It means that all four wheels of the car can receive driving force. The engine's power is distributed to all four wheels, making it less likely for the wheels to slip when encountering poor road conditions, greatly improving the car's passing ability.
I often use H4L mode when off-roading, such as driving a Toyota Land Cruiser. H4L stands for High 4WD Lock, which is one of the four-wheel-drive system settings. It locks the center differential to prevent wheel slippage, making it particularly suitable for muddy or snowy roads. However, I've noticed that beginners often use this mode on paved roads, thinking it enhances safety, but it may actually damage the drivetrain. Remember, only switch to H4L on unpaved surfaces, such as rural trails or slippery slopes—never in the city. Compared to 2H mode, H4L provides better stability and helps avoid getting stuck. Once during a desert expedition, I used H4L to easily traverse sand dunes, performing much better than regular 4WD. Regular maintenance of the drivetrain is also crucial—check the switches and wiring for any issues. If misused, the engine light might come on, requiring immediate repairs. In short, H4L is a great tool, but it must be used correctly to ensure safety and efficiency.
