Method to turn off the auto start-stop function on the Buick Excelle: Locate the start-stop system button on the vehicle's center console or the button area behind the gear shift, and press it once to deactivate. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts the engine when it's time to move forward again. The Buick Excelle is a premium mid-size sedan launched by SAIC-GM, with body dimensions of 4419mm in length, 1814mm in width, and 1487mm in height, and a wheelbase of 2685mm. In terms of exterior design, the Buick Excelle features the brand's signature winged chrome grille, giving the front fascia a sharper and more robust appearance. The combination of black piano vertical grille and high-gloss chrome winged grille naturally draws the visual focus of the front end to the emblem.
Every time I drive my Buick Excelle, I have to manually turn off the auto start-stop function because it's so annoying. The button is located below the left side of the steering wheel, with an 'A' icon. Just press it lightly, and the light turns on to indicate it's deactivated. I do this mainly because during city traffic jams, the engine shutting off and restarting causes significant vibrations and may affect battery life. The little fuel saved isn't worth the potential repair costs. If left on for long periods, it could also cause issues on slopes or slippery roads, so it's better to turn it off for peace of mind. I recommend new owners develop the habit of turning it off as soon as they get in the car, rather than letting it activate and cause trouble. After turning it off, the driving experience is noticeably smoother, and the battery lasts longer.
As a Buick Excelle owner, my view on the auto start-stop system is that it helps save some fuel and is good from an environmental perspective. However, if you want to turn it off, the operation is quite simple. Just locate the button with a circular arrow in the middle-lower part of the dashboard, press it once to deactivate the function, and press it again to reactivate. I usually keep it on, but I manually turn it off during peak traffic jams or long red-light waits to avoid frequent engine starts and stops that could wear out components. The feature is designed intelligently, but if it doesn't suit user habits—like when the startup noise affects comfort—it's fine to turn it off. After deactivation, the car's response becomes more consistent, but note that this isn't a permanent shutdown; you'll need to press the button again after each engine restart.
