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

The meaning of the engine energy-saving auto start-stop not being provided is: 1. Unable to function normally: The current state of the vehicle does not meet the requirements for the engine start-stop to operate normally. 2. Consequence: This will lead to the issue of the auto start-stop system not being provided. The reasons for the engine energy-saving auto start-stop not being provided are as follows: 1. The vehicle has not reached the ideal operating state: A low battery level or insufficient voltage can cause the auto start-stop to not work. This is because, during engine shutdown, the engine cooling fan and air conditioning require power to operate. The engine coolant temperature being too high or too low can also cause the auto start-stop to not work. 2. The vehicle has not reached the set state: In summer when the air conditioning is on, if the engine is turned off, the air conditioning compressor will not work. Once the temperature inside the vehicle differs significantly from the set temperature of the air conditioning, the auto start-stop system will restart the engine. 3. Other situations: When driving at low speeds, the speed does not reach 5 km/h after starting; or when repeatedly accelerating and decelerating with speeds below 15 km/h in certain cases.
I encountered a similar situation last time I was car shopping, meaning the vehicle wasn't equipped with an auto start-stop function and couldn't automatically shut off the engine at red lights or idle to save fuel. This is usually found in base model versions or specific brands, where this system is intentionally omitted in the design to avoid adding complexity and cost. As a car owner, I actually think it's fine without it—it eliminates the occasional slight shudder during startup, making driving smoother. Although fuel consumption might be slightly higher, the difference isn't significant in frequent city traffic jams. Daily driving habits like maintaining a steady speed or regular tire pressure checks can help offset this. Overall, it doesn't affect driving safety and even reduces stress on the battery and starter motor.
