How to Turn Off the Auto Start-Stop Function in the Excelle?

Auto Start-Stop Principle: 1. The working principle of the start-stop system is that when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts into neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensor of the anti-lock system shows zero; the electronic battery sensor indicates sufficient energy for the next start. 2. When these three conditions are met, the engine automatically stops running. When the traffic light turns green, the driver presses the clutch, and the 'start-stop device' can be activated immediately, quickly restarting the engine. In automatic transmission models, as soon as the brake is released or the steering wheel is turned, the engine automatically ignites again, allowing the driver to press the accelerator and start moving immediately, all while remaining in D gear.
Every time I drive my Excelle out, the first thing I do is turn off the auto start-stop function to prevent the engine from frequently starting and stopping in traffic jams. The vibration is really unbearable. It's simple to turn it off - right after starting the engine, quickly find the button with an "A" icon on the center console, usually near the gear lever. Press it, and the dashboard will display a lit icon indicating it's deactivated. When I first bought the car, I tried leaving it on in city areas with many traffic lights, and it was quite unpleasant. A friend also warned me that long-term use could damage the battery and shorten its lifespan. Now that I've made it a habit, driving has become much smoother with fewer maintenance worries. Occasionally on long highway trips, I'll reactivate it to test fuel efficiency, but most of the time, keeping it off provides better comfort.
As a car enthusiast who loves tinkering with vehicles, I've studied how the Buick Excelle's auto start-stop system works: it uses sensors to detect when the car is stationary and automatically shuts off the engine to save fuel, though it can be a bit annoying. Turning it off is actually quite simple—just press the start-stop button on the control panel after starting the car. The button is located slightly to the left on the center console and is labeled 'Aoff.' I've taken apart the dashboard to inspect the internal wiring, and frequent triggering of the system does consume battery power. That's why I recommend turning it off during rush hour commutes to avoid repeated engine starts and stops, which can wear out components. Also, check if the battery voltage is stable, as low voltage can cause the start-stop function to fail. Regular maintenance can extend the system's lifespan, but pressing the button to turn it off is the most hassle-free solution.
