When Tow/Haul mode is selected the Tow/Haul indicator light will illuminate. Four-Wheel Drive If your vehicle has four-wheel drive, you can send your engine's driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. See the appropriate text for the transfer case in your vehicle. Notice: Driving on pavement in four-wheel drive for an extended period of time may cause premature wear on your vehicle's powertrain. Do not drive in four-wheel drive on pavement for extended periods of time. The Tow/Haul mode also interacts with the Autoride™ feature, if your vehicle is so equipped, to enhance the ride when trailering or with a loaded vehicle. See Autoride™ on page 4-64.
