Can the Prado h4f and h4l be switched at will while driving?

[McAlina]

The Prado h4f and h4l can be switched while driving, but it is not recommended to do so arbitrarily. Characteristics of four-wheel drive: A manual transfer case is installed behind the transmission, and a component called the drive axle is installed on each of the front and rear axles. The torque output from the transmission is transmitted to the drive axles on the front and rear axles through the transfer case and drive shaft, and then the torque is transmitted to the wheels through the drive axles. Internal design of four-wheel drive: The four-wheel drive system is a full-time type, equipped with a viscous coupling, eliminating the need for a manual transfer case, and automatically distributing torque to the front and rear wheels as needed. On normal road surfaces, the four-wheel drive system distributes 92% of the engine's output torque to the front wheels and 8% to the rear wheels; on slippery road surfaces, at least 40% of the engine's output torque is distributed to the rear wheels. When the front wheels begin to slip, the speed difference between the front and rear wheels will cause the viscous fluid in the coupling to immediately thicken and lock the coupling, so that the drive shaft only transmits torque to the rear wheels.
