What to Do When the Start-Stop System Malfunctions?
2 Answers
It is recommended to immediately contact a 4S dealership for inspection and repair. The causes of engine start-stop system malfunctions may include issues with the starting system and circuits, faults in the engine electronic control system, or problems with the anti-theft system. Below is an introduction to the automatic start-stop function: 1. Definition: The automatic start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) and restarts the engine when it's time to move forward again. 2. Main Purpose: Used when the vehicle is moving at low speeds or stopping repeatedly, it can automatically turn off the engine to avoid unnecessary fuel consumption, reduce the vehicle's idle time, and consequently decrease engine carbon buildup.
My car's start-stop system reported an error two days ago, and the repair shop found it was a battery issue. The start-stop system requires a high instantaneous current during activation, and it automatically deactivates when the battery voltage drops below 12V. Daily tips: Turn off power-consuming features like seat heating while driving, and avoid listening to music for extended periods after turning off the engine. In winter, remember to drive on the highway to fully charge the battery, as the start-stop system only functions properly when the battery is fully charged. If the yellow start-stop warning light appears on the dashboard, don’t rush to press the start button—let the system perform a self-check first, as some temporary issues may resolve automatically after driving a couple of kilometers. If the system fails to start three times in a row, get the battery capacity checked immediately.
