The Electronic Stability Control (ESC) system helps to stabilize the vehicle during cornering maneuvers. ESC checks where you are steering and where the vehicle is actually going. ESC applies braking pressure to any one of the vehicle's brakes and intervenes in the engine management system to assist the driver with keeping the vehicle on the intended path. It is not a substitute for safe driving practices. Always adjust your speed and driving to the road conditions.
WARNING
Never drive too fast for the road conditions or too quickly when cornering. The ESC system will not prevent accidents.
Excessive speed in turns, abrupt maneuvers, and hydroplaning on wet surfaces can result in severe accidents.
