How to Use the Engine Start-Stop System?

The method of using the engine start-stop system: 1. Once the car is started, the engine automatic start-stop system is in normal working condition. When encountering a red light or other reasons to stop, step on the brake, and generally after two seconds, the engine will automatically shut off; 2. When ready to start again, simply release the brake, step on the accelerator, or gently turn the steering wheel, and the engine will restart. The engine automatic start-stop system automatically shuts off the engine when temporarily stopping during driving and automatically restarts the engine when needing to move forward again. The working principle of the automatic start-stop system: By implanting an enhanced motor with idle start-stop function in a traditional engine, the engine completely shuts off when the vehicle meets the idle stop condition. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly starting the engine for instantaneous connection.
When I first got my car, I also looked into this feature. Essentially, it automatically shuts off the engine when you come to a complete stop while driving, and the engine instantly restarts when you release the brake at a green light. When the air conditioning is on, the stop time is noticeably reduced, as maintaining cabin temperature takes priority. After getting used to it, I turn off the auto start-stop button—located just below the left side of the steering wheel—during heavy traffic, as frequent restarts can actually consume more fuel. I recommend that beginners also turn it off when maneuvering in parking garages, as constant engine shut-offs can be quite annoying. This system places high demands on the battery, so replacements must be of the auto start-stop specific type, which is significantly more expensive than regular batteries.
