What does 'service' mean when it appears on a car?

[OClara]

"Service" is a maintenance reminder, alerting the car owner to perform maintenance at specified mileage intervals as needed. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. After a car reaches a certain mileage, the owner should promptly replace the necessary parts. After maintenance is completed, the maintenance reminder light needs to be reset following a specific procedure to turn it off. If the indicator remains after maintenance, the following steps can be taken to clear it (methods may vary for different car models): 1. Insert the key but do not turn it. 2. Press and hold the lever next to the odometer for 5-10 seconds, then turn the key to the "on" position. 3. After another 5-10 seconds, start the car. Continue holding the lever throughout this process without releasing it. Following these steps should clear the wrench indicator. If it does not clear, repeat the same process.
