What does the small wrench on the dashboard indicate?

[SanKatherine]

The small wrench on the dashboard indicates that it's time for car maintenance, not that there is a malfunction with the vehicle. Manufacturers set a parameter when the car is produced, and once a certain mileage is reached, the "small wrench" will appear to remind the owner that the car needs maintenance. Typically, the maintenance interval for a car is every 5,000 to 8,000 kilometers, although the factory-set interval is usually slightly longer than 8,000 kilometers. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. The purpose of car maintenance is to keep the car clean, ensure normal technical conditions, eliminate potential hazards, prevent malfunctions, slow down the deterioration process, and extend the vehicle's service life.
