The following three systems help to control your vehicle while driving -- brakes, steering, and accelerator. At times, as when driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. Meaning, you can lose control of your vehicle. See Enhanced Traction System (ETS) .

Adding non-dealer/non-retailer accessories can affect your vehicle's performance. See Accessories and Modifications .
