Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description And Operation: Description
Idle Stop & Go (ISG) System switches off the ignition when vehicle is stopped, and then restarts the ignition and starts the vehicle when accelerator is pushed. It temporarily stops the engine while waiting for signal or idling to improve fuel efficiency and reduce exhaust gas emission. However, ISG system may not operate if engine oil or ambient temperature is too low, or if 12V battery voltage is too low. The system can be deactivated by pushing the ISG OFF switch when the driver wishes not to use ISG system.
Sample scenario: switching off the engine at a standstill at a red traffic light or in stop-and-go traffic.
