While using a four-wheel drive system driving on flat, dry surfaces is not recommended because of the potential damage it could cause to the drive train, it is extremely helpful at making a dangerous driving situation safer.

High-range four-wheel drive is designed to handle moderately difficult driving conditions such as snow, ice or flat surfaces with loose covering. This allows for traveling at normal highway speeds safely. For deep mud, snow, sand and other highly dangerous situations, low-range four-wheel drive is more appropriate. When using this system, it is important to drive at lower speeds.

Automatic four-wheel drive switches from two-wheel drive to four-wheel drive whenever the vehicle begins to slip. Regardless of the conditions that cause the four-wheel drive to kick in, it is important to drive at a slow enough speed that the vehicle can be brought to a complete stop quickly and easily.
