What does the wrench light on the car dashboard mean?

The small wrench is a maintenance reminder indicator. This is a maintenance alert function. The owner should take the vehicle to a service center for inspection. The wrench warning is set by the car manufacturer to remind owners to perform maintenance at specified mileage intervals. After maintenance is completed, the reminder light must be reset following a specific procedure to turn it off. It's also possible that the reminder wasn't reset during the last maintenance, requiring another reset. Here is some relevant information: 1. The wrench warning light on the dashboard illuminates every 5,000 kilometers or six months (whichever comes first). When the maintenance light comes on, you can go to a repair shop to change the engine oil and oil filter. After replacement, ask the technician to reset the maintenance light so it can remind you for the next scheduled maintenance. 2. The vehicle's maintenance cycle is preset during manufacturing, so the "small wrench" indicator will appear at regular mileage intervals to remind the driver to perform timely maintenance.
Yesterday, my neighbor Lao Wang was driving when a wrench symbol suddenly appeared on his dashboard, and he rushed over to me in a panic. I explained to him that this wrench icon is the car's built-in maintenance reminder function, just like a schedule alert on a phone. The car's system tracks mileage and usage time, and the light comes on when it reaches the manufacturer's preset maintenance interval. Different car models have different trigger conditions: most German cars go by mileage, while Japanese cars also factor in time. My advice is to schedule maintenance as soon as you see this symbol—don't push your luck. Last time I delayed an oil change, it led to engine knocking, a lesson learned the hard way. It's good practice to note down your last maintenance mileage, so you have a clear idea when the light comes on.
