Basic Circuit Protection Features: The built-in simple circuit buffer structure can withstand minor voltage fluctuations and instantaneous current surges in the vehicle, protecting core components from circuit fluctuations. This feature automatically shuts off the engine when the vehicle comes to a temporary stop—such as at a red light or in a traffic jam—and quickly restarts it when the brake is released or the accelerator is pressed. Its purpose is to save fuel and reduce exhaust emissions. The primary function of the engine start-stop switch is to enable or disable the automatic start-stop system.
