The traction control system comes into play while the car is accelerating. It prevents your car from losing control during acceleration and helps the vehicle regain traction. The system also comes in handy when your car is turning the corner. While turning corners, the wheels are likely to slide more. The feature will prevent this by controlling the power to the wheels. The traction control system operates best when there is a discrepancy between the acceleration of the wheels and the acceleration of the vehicle, which happens mostly on slippery roads.
