Electronic stability control (ESC) is a safety feature in cars that helps the driver maintain control of the vehicle and helps prevent it from spinning out due to a loss of traction. ESC is also known as Vehicle Stability Control, Electronic Stability Program, Dynamic Stability Control, and other names. The system is on by default and works automatically and unobtrusively in the background until needed.
ESC instantly activates when the computer-controlled system senses a probable loss in steering control. The system works by modulating the engine throttle and each wheel’s brake. If the system determines the driver is losing control of the car, ESC reduces power output and applies the brakes of each wheel to bring the vehicle back onto its intended path of direction. ESC also works with the car’s traction control system to prevent the vehicle from skidding or rolling over. Leave your car’s electronic stability control engaged, except for rare cases in which you want more wheel spin for the car to get out of deep snow or sand or when driving with snow chains.
