How to Deactivate the Auto Start-Stop Function?

Engine auto start-stop can be manually deactivated via a switch in the vehicle. However, it cannot be permanently disabled; you need to manually turn it off each time you start the car. Auto start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop during driving. When it's time to move again, the system automatically restarts the engine. Below is an introduction to how the start-stop system works: 1. The Start/Stop system automatically detects when the engine is idling and no gear is engaged. 2. The wheel speed sensors of the anti-lock braking system indicate zero rotation. 3. The electronic battery sensor shows sufficient energy for the next start. 4. When these three conditions are met, the engine automatically stops.
My own car comes with an auto start-stop function, and at first, I was always startled when the engine suddenly shut off at red lights. After some research, I found that most models have a button with an 'A' inside a circle near the dashboard; pressing it to light up the indicator turns the function off. For example, in my Volkswagen, it's located on the left side of the center console's air conditioning panel, while some cars have it designed near the gear shift area. It's a bit of a hassle to turn it off manually every time after starting the engine. Some car owners have managed to permanently disable it by tweaking hidden settings, but this operation carries risks and may void the factory warranty. Personally, I prefer to manually press the button. The fuel-saving effect of auto start-stop is limited, and frequent restarts might actually shorten the battery's lifespan. Turning this feature off can be more worry-free.
