When to use 4high and 4low when usein 4x4?

In a 4x4 vehicle, use 4High when you need extra traction on slippery surfaces like wet roads, gravel, or light snow, and you're traveling at higher speeds (up to 55 mph). Engage 4Low when you require maximum torque for challenging terrain, such as steep inclines, deep mud, or heavy snow, and when driving at low speeds. Always switch to the appropriate mode based on the driving conditions to ensure optimal performance and safety.
