How to Use the Auto Start-Stop Function in a Sedan?

[MacMaverick]

Auto Start-Stop is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving (such as waiting at a red light) and restarts the engine when it's time to move forward again. In simple terms, it's a system that can automatically control the engine's shutdown and ignition, abbreviated as STT. The method to use the auto start-stop function in a sedan is as follows: 1. Status: The car's engine auto start-stop system is in normal working condition. 2. Auto Shutdown: When encountering a red light or stopping for other reasons while driving, the engine will automatically shut off after pressing the brake for two seconds. 3. Startup: When it's time to start moving again, simply release the brake, press the accelerator, or gently turn the steering wheel, and the engine will restart.

When encountering traffic jams or red lights while driving, I use the auto start-stop function to control fuel consumption. First, after starting the vehicle, the system is usually enabled by default. When the car comes to a complete stop and the brake is firmly pressed, the engine automatically shuts off; releasing the brake or lightly pressing the accelerator instantly restarts it to continue driving. Note that the system only works when the battery has sufficient charge, the temperature is normal, and the vehicle is stable. If the slope is steep or the air conditioning is running too hard, it may automatically disable. For new drivers, I recommend practicing first on open roads to get used to it and avoid sudden braking or abrupt releases. When traffic gets frustrating, pressing the center console button to turn it off can save hassle. Overall, it can save about 10% in fuel, but be mindful not to let the engine wear out from frequent starts and stops—it’s quite handy for daily use.

Over the years of driving automatic transmission cars, I find the auto start-stop feature very convenient. The system activates automatically after engine ignition without requiring any setup. The engine shuts off when coming to a complete stop with brakes pressed, and restarts upon releasing the brakes to move. It saves considerable fuel especially in areas with frequent traffic lights. However, there are details to note: the system may malfunction when engine temperature is low in cold weather; it's also prone to issues with aging batteries or heavy loads like running AC on hot days. For long-term use, I recommend regularly checking battery voltage to ensure stable functionality, and manually deactivating the button if frequent restarts become noisy during highway driving. Overall, it's eco-friendly and safe, reducing stationary emissions while being economical.

Using the auto start-stop system is straightforward, with safety as the top priority. After the vehicle comes to a complete stop and the brake is firmly pressed, the engine shuts off; releasing the brake automatically restarts it. The key point is that on slopes or slippery roads, the system intelligently disables itself to prevent rolling risks. After starting, simply check the dashboard indicator light to confirm the status; during traffic congestion, manually turn it off to reduce fatigue.
