If you live in an area where there is a lot of snowy and icy weather, four-wheel drive is an important feature to help you get where you want to go. Most four-wheel drive vehicles are equipped with a four-high and a four-low function. Auto Solutions in Maryville, TN wants to provide some tips on when 4H and 4L should be used.
You can use 4H when you are driving at a normal rate of speed. If you are driving on the highway and the snow is falling using 4H is the way to go. You can also use 4H when you are driving on sandy and rocky roads where you need better traction.
You should only use 4L when traveling under 40mph. 4L routes significant torque to the wheels to get you out of really tricky situations such as deep snow and mud. Going too fast in 4L can damage your vehicle, so be cautious.
