What does a small wrench on the dashboard mean?

[LaDawson]

A small wrench on the dashboard is a maintenance indicator light, which means the car needs maintenance, not that there is a fault with the car. Its main function is to remind the owner to perform maintenance on the vehicle. Not all vehicles have this function. For vehicles equipped with this feature, the manufacturer sets a parameter at the factory, and the "small wrench" will appear when the vehicle reaches a certain mileage. Typically, the maintenance cycle for a car is between 5,000 to 8,000 kilometers, with the factory-set cycle often exceeding 8,000 kilometers. The appearance of the small wrench symbol does not affect the normal operation of the vehicle, and the symbol will disappear after maintenance is performed.
