How to Turn Off BMW Auto Start-Stop?

[DeJourney]

The method to turn off BMW auto start-stop is: 1. The start-stop off button is located below the engine start button; 2. Manually press the A OFF button to deactivate the start-stop function. Auto start-stop refers to a system that automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at traffic lights) and restarts it when driving resumes. BMW models include: BMW X1, BMW 3 Series, BMW X5, BMW X6, BMW X7, etc. Taking the 2021 BMW X1 as an example, it is a compact SUV with body dimensions of: length 4565mm, width 1821mm, height 1620mm, and a wheelbase of 2780mm.

I can share my experience on how to turn off the auto start-stop function in BMW. I drive a BMW 3 Series, and every time I start the vehicle, the start-stop system activates automatically. When stopping at a red light, the engine shuts off, but I always find the resulting vibration a bit annoying, especially in urban traffic jams. Later, I learned a simple method: there's a dedicated button on the center console to the left of the steering wheel, labeled 'A' or 'Auto Start Stop OFF.' Pressing it immediately deactivates this function. Once turned off, a warning light will appear on the dashboard. However, note that this is only a temporary deactivation—the system defaults to 'on' every time you restart the car, so you'll need to press the button again. I find this helpful in reducing unnecessary vehicle jolts, especially when running the AC on hot days. Additionally, if the battery is low, the start-stop may not work, but this doesn’t affect manual deactivation. Making it a habit to turn it off right after starting the car makes driving much more comfortable.

As a frequent driver, I've developed the habit of manually turning off the automatic start-stop system in my BMW, as frequent activations can drain the battery or cause engine vibrations. The operation is simple - locate the physical button near the air conditioning controls on the center console and press it to immediately deactivate the function. Having tried several models like the BMW 5 Series or X3, I confirm the configuration and operation are identical across these vehicles. Disabling it makes for smoother acceleration from traffic lights. While the iDrive system offers temporary deactivation, the physical button provides quicker access. Though designed for fuel efficiency and environmental benefits, the system shows limited effectiveness in city driving while potentially increasing engine wear. I recommend making it a routine to press the button upon starting the car to prevent interference. If system malfunctions occur (like the engine warning light illuminating) and the feature can't be disabled, professional inspection becomes necessary. Overall, this simple trick significantly enhances the driving experience.

Turning off BMW's start-stop system is simple: After starting the car, immediately locate the 'OFF' button on the left console of the steering wheel. Press it, and the system will deactivate. I always do this while driving to avoid the annoyance of the engine repeatedly shutting off. If the button doesn't respond, check the battery status or visit a 4S shop for maintenance.
