How to Turn Off the Auto Start-Stop Function on BMW X3?

Method to disable the auto start-stop function on BMW X3: The auto start-stop deactivation button is located on the engine start button. Simply press the 'A off' button manually to turn it off. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when needed to proceed. The BMW X3 is a mid-size SUV under the BMW brand, with dimensions of 4648mm in length, 1881mm in width, and 1661mm in height, and a wheelbase of 2810mm. The intelligent all-wheel-drive system of the BMW X3 can flexibly and quickly distribute driving force between the axles according to specific road conditions, ensuring strong traction whether on sharp turns, steep slopes, or slippery surfaces. Additionally, the DSC sensor can detect understeer and respond immediately by sending more power to the rear wheels.
I also own a BMW X3, and the auto start-stop feature really annoyed me at first—the engine kept shutting off and restarting at red lights, making quite a bit of noise. Turning it off is simple: After starting the car, look for the button in the control area below the left side of the steering wheel, usually marked with the letter 'A' inside a circle or labeled 'OFF.' Press it once, and when the light turns on, the auto start-stop is disabled. However, there's a catch: Every time you turn off and restart the car, the feature defaults back to being active, so you’ll need to manually disable it again. If that’s too much hassle, you can go into the iDrive system’s vehicle settings, find the driving options, and select to disable auto start-stop. I prefer turning it off in heavy city traffic because frequent restarts add strain to the engine and slow down acceleration response. If you're unsure about the button’s location, checking the owner’s manual is a safe bet—different X3 versions might have slightly different layouts.
