Sometimes the road gets greasy than AWD control the system locks the axles and automatically distributes power to all four of the tires. If the AWD system allows the driver to switch to a "low" range gearing setting, like in the Dodge Durango and Toyota 4Runner, then it is probably planned for severe off-road use.
4wd vehicles found help in the gearing option with equipment of off-road driving. Following are a variety of conditions in which you would want to use 4WD to avoid downhill or spinning:Hi Range 4WD
