Once the car reaches the required mileage, it will trigger a prompt to remind the owner to perform maintenance. To clear the engine oil replacement reminder, you can choose to go for maintenance. During the maintenance visit, a specialized computer system at the 4S dealership can be used to cancel the prompt.

Modern car maintenance mainly includes the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas. The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. If you don’t develop the habit of regular car maintenance, it can lead to significant wear and tear on the car and also affect its appearance. Reasonable and regular car maintenance ensures that the car remains in optimal condition in all aspects, providing better service to the driver and passengers.
