Whether out in the country or cruising the freeway, a 4WD SUV can be a necessity. Although technically a passenger vehicle, it is also a tool, orange polo shirts thus the word "utility" as in "sport utility vehicle". Like any new tool, a 4WD SUV will take some time to master, and the rules are different for both on and off road use; instructions must be followed for optimum performance - and fun!
Four wheel drive SUV's generally have three drive train settings: auto (2WD or "auto" on the selector), four high (4H on the selector), and four low (4L on the selector). These settings simply tell the driver how many wheels are driving the vehicle at any given time, and how much power is being transferred to those wheels. For instance, when the vehicle is in 2WD, only two wheels are driving the vehicle, just like a standard car. When the setting is changed to 4H, so it the same as a 4x4 vehicle, more power is transferred to the wheels, and it can be driven at highway speeds. 4L is known as the "granny gear"; all four wheels are driving the vehicle orange polo shirt with maximum power, and it can only be driven very slowly.
