Civic auto start-stop permanent disabling methods: 1. Press the auto start-stop button, usually a circular arrow with an A inside. After pressing, the indicator light on the dashboard will illuminate, indicating the auto start-stop system is deactivated; 2. Visit a 4S dealership where technicians can connect a laptop or tablet via the OBD interface to modify settings to either default off or remember the last state, or completely disable the function. The auto start-stop system is quite convenient to use - while driving, simply press the brake pedal firmly and the engine will automatically shut off approximately two seconds after the vehicle comes to a complete stop. Keeping the brake pedal depressed maintains the engine in shutdown state. Engine auto start-stop automatically turns off the engine when temporarily stopping during vehicle operation.
My car is a Civic, and the auto start-stop function is the most annoying thing. I have to press the disable button every time I get in the car. After researching various methods, the most practical solution is a physical modification: open the hood, locate the battery negative sensor—that small square box—and unplug its connector. After unplugging, remember to wrap the wire ends with tape to prevent short circuits. The dashboard might show a warning light, but it doesn’t actually affect driving. There are auto start-stop disablers sold online for around 200 yuan; just plug them in and they’ll work. However, be aware that tampering with wiring may void the warranty, and the dealership will definitely bring it up. If you’re serious about doing this, it’s safer to go to a professional modification shop. Right now, with the AC on in this hot weather, the auto start-stop doesn’t engage anyway, so that saves some hassle.
