Can the Engine Start-Stop Function Be Turned Off?

Engine start-stop can be turned off via a switch in the car, but it cannot be permanently disabled. It requires manual deactivation each time the vehicle is started. The operation method of the engine start-stop technology is as follows: 1. After the car is started, the auto start-stop system remains in normal working condition; 2. When encountering traffic lights or other reasons for stopping, stepping on the brake will automatically shut down the engine; 3. To restart, release the brake and press the accelerator, or turn the steering wheel. Conditions for the engine start-stop technology to automatically cease operation include: 1. The engine is idling and not in gear; 2. The wheel speed sensor of the anti-lock system indicates zero; 3. The electronic battery sensor shows sufficient energy for the next start.
The most annoying thing about driving is the auto start-stop feature. Every time you stop at a red light, the engine shuts off, and the sudden restart is particularly uncomfortable. In city traffic, the frequent engine starts feel like they're damaging the car. Turning it off is actually quite simple—there's usually a start-stop button on the center console, typically marked with an 'A' surrounded by an arrow. Press it until the light comes on, and it's deactivated. From my experience, driving becomes much smoother after turning it off. No more hearing the abrupt engine restart at red lights, especially noticeable when using the AC in summer. Some car models have it enabled by default, requiring manual deactivation every time you start the car, so I've made it a habit to press the button before driving. Although car manufacturers claim it saves fuel, my real-world tests show minimal savings.
The start-stop function can indeed be turned off; it's just a matter of pressing a button. However, keeping it disabled for extended periods may affect the battery lifespan, as vehicles equipped with start-stop systems come with specialized AGM batteries. I usually handle it situationally: I turn it off in traffic jams to avoid frequent restarts, but keep it active on highways where it's more practical. Note that the system automatically deactivates when outside temperatures drop below freezing or when the air conditioning is on, rendering the button ineffective during these times. The primary advantage of this feature is reducing exhaust emissions, but honestly, the vibration from automatic restarts always makes me worry about engine damage, so I mostly keep it turned off except for long trips.
