What do H4 and L4 mean in the Prado?
2 Answers
"H4" stands for High-speed 4-wheel drive, while "L4" stands for Low-speed 4-wheel drive. High-speed 4WD is suitable for driving on gravel roads, muddy surfaces, snow, and sandy terrain, with the maximum speed generally limited to 80 km/h. Low-speed 4WD provides higher torque, making it more powerful and suitable for off-roading, climbing steep slopes, descending steep inclines, and escaping difficult situations, but it is rarely used for continuous driving. When using 4L, it's best to start in 1st gear and avoid shifting to gears higher than 2nd, while also keeping the speed relatively low. "4-wheel drive" means the vehicle maintains all four wheels driving throughout the journey, with the engine's torque distributed to the front and rear wheels at a fixed ratio. This driving mode ensures good off-road and handling performance at all times, but it cannot adjust torque distribution based on road conditions and tends to have higher fuel consumption.
If you're asking about the H4 and L4 in the Toyota Land Cruiser, they refer to the four-wheel drive system modes of this vehicle. H4 stands for high-speed four-wheel drive, which is very practical for driving in rainy or snowy weather or on small dirt roads. You can go a bit faster while maintaining good tire traction. L4 is low-speed four-wheel drive, specifically designed for steep slopes or large rocks—it offers slow speed but extremely strong torque, making it great for towing or climbing hills without worry. Having driven off-road for many years, I know that switching between these modes on the Land Cruiser is done via the knob or button on the central console. Just be sure not to misuse L4 on paved roads, as it can damage the driveshaft. Regular checks on the four-wheel drive system are essential to prevent small issues from becoming big problems. Modern four-wheel drive systems have evolved significantly—H4 is suitable for light adventures, while L4 is for hardcore off-roading, ensuring every trip is safe and fun. In short, understanding these modes will make your journeys more confident.
