How to Turn Off the Auto Start-Stop Function in a Mercedes-Benz?

To turn off the auto start-stop function in a Mercedes-Benz, press and hold the auto start-stop switch. The working principle of the auto start-stop system is as follows: when you brake to a stop and shift into neutral, the system automatically detects that the engine is idling and no gear is engaged, the speed sensor shows zero, and the battery sensor indicates sufficient energy. The engine then automatically stops. When you depress the clutch, release the brake, or turn the steering wheel, the system quickly restarts the engine. Taking the Mercedes-Benz S-Class 2021 model as an example, its body dimensions are: length 5290 mm, width 1921 mm, height 1503 mm, wheelbase 3216 mm, and fuel tank capacity 76 liters.

I've been driving a Mercedes for several years and find the auto start-stop function a bit annoying, especially in city traffic jams. Turning it off is quite simple: after starting the car, there's a button with the letter 'A' on the left side of the steering wheel or near the gear shift. Press it once, and the dashboard will display that start-stop is deactivated. In Mercedes vehicles, this function automatically activates every time you start the engine, so you have to turn it off each time you drive. I prefer to keep it off because it reduces vibrations during startup, makes the ride quieter, and decreases engine load, prolonging component lifespan. It's especially important to turn it off when driving through water to avoid the risk of stalling and restarting. Mercedes' system is very smart, but driving feels noticeably smoother with it turned off, eliminating that momentary jerk when waiting at traffic lights—it's quite practical.

As a young car owner, I find it not complicated to turn off the Mercedes-Benz auto start-stop function. There's a small button marked with the start-stop symbol on the gear lever or center console, usually a circle with an 'A'. Press it until the indicator light comes on, which means it's deactivated. Mercedes-Benz defaults to having it enabled after startup, so you need to operate it every time you get in the car. I recorded a short video on my phone to save it, and my friends understood it at a glance. After turning it off, there's no more engine start-stop noise at red lights, and the car starts more crisply. I heard the Mercedes system is designed for fuel efficiency, but turning it off can actually protect the battery from frequent use. Remember to adjust the lighting when operating in garages or tunnels to clearly see the button position.

I'm a detail-oriented user who pays attention to the auto start-stop function when driving a Mercedes. The method to turn it off is straightforward: after starting the car, look for the 'A' button near the gear shift lever and press it to deactivate the system. Mercedes-Benz designs it to reactivate the auto start-stop function upon each engine start, so it's necessary to develop the habit of manually turning it off. It's recommended to disable this feature during rainy days or heavy traffic to reduce the risk of unexpected engine restarts and ensure safety. The whole process takes just a few seconds and noticeably enhances the quietness and comfort inside the vehicle.
