To turn off the auto start-stop function in a BMW, press the 'A Off' button located below the engine start button. BMW's model lineup includes the BMW X1, BMW X2, BMW X3, BMW X4, BMW X6, among others. Taking the 2021 BMW X1 as an example, it is a compact SUV with body dimensions of 4565mm in length, 1821mm in width, and 1620mm in height, with a wheelbase of 2780mm. The 2021 BMW X1 is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 140PS, a maximum torque of 220Nm, and a maximum power output of 103kW, paired with a 7-speed dual-clutch transmission.

Turning off the auto start-stop function on a BMW is actually quite simple. I often do this when driving my BMW because this feature frequently shuts off and restarts the engine in city traffic jams, which can be quite uncomfortable. Usually, after starting the vehicle, you'll find a button below the dashboard on the left side of the steering wheel labeled "A Off" or with a similar icon. Pressing it once will turn it off. You may need to do this again after each ignition because BMW designs it to default to on for fuel efficiency. If you have a newer model with the iDrive system, you can also find the "Driving Assistance" or "Vehicle Settings" option in the central control screen menu and turn off "Auto Start-Stop" there. After doing this, the engine won't automatically shut off when stopping, making for smoother starts. Some car enthusiasts also recommend regularly checking the battery life, as frequent start-stops can accelerate battery aging. Overall, turning it off improves driving comfort, especially during short commutes.

The method to disable auto start-stop varies by model. BMW implements this feature for environmental protection and fuel efficiency, using sensors to shut off the engine when stationary to save fuel. However, in practical use, its frequent restarts may cause vibrations, diminishing driving pleasure. Operationally, there is typically a physical button inside the car, located at the lower left of the dashboard with an "A" symbol—press it lightly to deactivate. Alternatively, use the iDrive system to navigate to the "Eco Mode" section in the "Settings" menu and disable the start-stop function. If you wish to permanently disable it, programming tools are required, but I do not recommend beginners attempt this to avoid affecting the vehicle's safety settings. After deactivation, you may notice quicker power response, especially in traffic jams. Remember to check if the air conditioning system operates more stably as a result.

Turning off the auto start-stop is simple. After starting the car, locate the button with the "A Off" symbol on the dashboard and press it. This feature often causes the engine to shut off automatically during city driving, creating vibrations, so disabling it provides a more comfortable ride. BMW designed this fuel-saving function, but it can cause significant wear on older engines. Additionally, there's a setting option in the iDrive system where you can disable it using the rotary knob or touchscreen under vehicle settings. You'll need to repeat this process after each ignition since it cannot be permanently turned off.
