[EvangelineLynn]

Generally, a major maintenance is performed every 40,000 kilometers. Car Maintenance: Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life. Major Maintenance: Replace the air filter, cabin air filter, fuel filter, transmission fluid, brake fluid, antifreeze coolant, spark plugs, etc. Tires and brake pads should be thoroughly inspected, and if severe wear is found, they must be replaced promptly. Check if the timing belt shows signs of aging, and if any abnormalities are found, it should also be replaced in time.
