What is the Engine Start-Stop Button?
2 Answers
The engine start-stop indicator button features a circle with an 'A' inside and the letters 'OFF' below it. Here is additional information about the start-stop function: 1. Purpose: The automatic start-stop function automatically shuts off the engine when the vehicle comes to a stop and restarts it when the clutch is pressed, saving time. 2. Working Principle: The start-stop system operates as follows: when the vehicle stops due to traffic or at an intersection, the driver can press the brake pedal and shift to neutral. The Start/Stop system then automatically checks conditions such as the engine idling without gear engaged, wheel speed sensors from the anti-lock system showing zero, and the electronic battery sensor indicating sufficient energy for a restart. The entire process occurs while the transmission remains in Drive (D) mode.
The engine start-stop button is the one in the car, usually marked with a capital 'A' inside a circle or labeled ENGINE STOP START. It's typically located near the steering wheel or on the center console, and pressing it toggles the auto start-stop function. Here's a real-life example: When I drive in the city, I often use it—the engine automatically shuts off when stopped at a red light to save fuel, and restarts instantly when I press the accelerator at green light. It's quite convenient and saves a lot on gas money. Its position varies by car model—some place it at the lower left of the dashboard, others near the gear shift. It's best to check the owner's manual to confirm. However, frequent starts can accelerate wear on the engine and battery, especially in heavy traffic or cold weather, so I turn it off to prevent battery drain. It's a common feature in new cars, simple to operate with just a press, and doesn’t affect driving—though there’s a slight vibration during restart, which is normal. Overall, it’s a practical feature that reduces emissions, and you’ll get used to it with more use.
