What does it mean when the engine energy-saving auto start-stop is not provided?

[StClara]

Engine energy-saving auto start-stop not being provided means the vehicle's current condition cannot meet the normal operation requirements of the engine start-stop function, resulting in the auto start-stop system being unavailable. Here are the relevant explanations: 1. Reasons for the issue: The causes may include insufficient battery charge or winter usage conditions. The auto start-stop system has specific operating temperature ranges and cannot activate when outside these parameters. 2. Auto start-stop function: The engine auto start-stop function automatically shuts off the engine when the vehicle comes to a temporary stop during driving. When ready to move again, the system automatically restarts the engine. Also known as STT intelligent fuel-saving system, this feature is now equipped in most vehicle models.
