Residual Circuit Power Management: Assists in releasing residual power in the circuit upon engine shutdown, regulating the electronic control circuit state and preventing residual current from continuously impacting vehicle electrical components and engine parts. 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.
