Control of a Vehicle
You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering, and the accelerator.
All three systems have to do their work at the places where the tires meet the road.
Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle.
Adding non-GM accessories can affect your vehicle’s performance.
