The high gear (4H) and low gear (4L) of the four-wheel drive system need to be selected according to the road conditions. 4H is suitable for wet and slippery roads or mild off-road conditions, such as rainy roads, gravel roads or muddy terrain, which can enhance traction and allow high-speed driving, while 4L is used for extreme terrain, such as steep slopes, deep sand or rock climbing, to enhance the ability to escape by amplifying torque, but low-speed driving is required to avoid overloading the transmission system. When switching, the vehicle needs to be parked in neutral, and some models also require manual locking of the differential. It is worth noting that long-term use of 4H on paved roads may increase fuel consumption and component wear, while misuse of 4L for high-speed driving can lead to mechanical damage. Therefore, it is important to understand the recommendations in the vehicle manual. In addition, modern four-wheel drive technologies such as full-time four-wheel drive or on-demand four-wheel drive can automatically distribute power, but traditional part-time four-wheel drive still requires manual switching. It is recommended to operate flexibly according to actual needs, and regularly check the transmission system and tire condition to ensure performance.
