What Causes the Start-Stop Function to Fail?

[LucasRose]

Here are the reasons why the automatic start-stop function may fail: 1. The battery temperature is too high or too low. 2. The battery charge is too low. 3. The vehicle is on a steep slope. 4. The cabin is being heated or cooled and has not yet reached an acceptable temperature. 5. The engine has not reached its normal operating temperature, or the transmission is not in drive mode. Below is additional information about the engine automatic start-stop system: 1. Definition of automatic start-stop: It is a system that automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and automatically restarts the engine when it's time to move forward. 2. Function: During red lights or traffic jams, the system minimizes engine idling time to reduce unnecessary fuel consumption. Turning off the engine while stopped effectively reduces noise and vibration, providing a better driving experience.
