4S store maintenance mainly includes the following items: Oil and oil filter replacement (10,000 km): The replacement of the oil filter is mainly for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine and prevent excessive wear. The oil filter removes various impurities from the oil to ensure the normal operation of the lubrication system. When changing the oil, the oil filter should be replaced together with the oil. Normally, a car needs maintenance every 5,000 km. Fuel filter (30,000 km): Removes impurities and moisture from the fuel, allowing the engine to perform at its best. Spark plugs (Platinum: 60,000 km; Iridium: 80,000 km): Prevents ignition difficulties and insufficient engine power. Brake fluid (40,000 km): Absorbs moisture from the air, improves braking performance, and ensures driving safety. Brake pads (should not be less than 3mm): Prolonged driving can cause severe wear on the brake pads, reducing braking effectiveness. Replacing the brake pads ensures stable handling performance. Air and cabin air filters (30,000 km): Improves the quality of intake air, allowing the air distribution system to function efficiently; enhances air quality by filtering dust and unpleasant odors. Overall vehicle inspection: A comprehensive check of the car to ensure driving safety. Car maintenance typically includes the following aspects: Cleaning: Cleaning and wiping the interior and exterior surfaces of the car, as well as removing dirt from various filters, carbon deposits in the combustion chamber, and scale from the cooler. Lubrication: Adding or filling lubricants to various lubrication points, as well as topping up or replacing the lubricating oil in the engine, transmission, steering system, and main drive. Tightening: Mainly involves tightening bolts and nuts of threaded connections. Inspection: Primarily checks the working performance and local conditions of the car, such as braking distance and wear of brake pads, engine power and cylinder pressure, and whether the oil and electrical systems meet specifications. Adjustment: Based on inspection results, adjusts car assemblies or components to meet specified technical conditions. Body maintenance. Body maintenance is also commonly referred to as car detailing. The main purpose is to remove oxidation and corrosion from the exterior and interior of the car and then protect it to highlight the car's "beauty." It mainly includes: paint maintenance, seat and carpet maintenance, bumper and skirt maintenance, dashboard maintenance, chrome plating maintenance, leather and plastic maintenance, tire and wheel hub warranty, windshield maintenance, chassis maintenance, and engine exterior maintenance. Interior maintenance. While body maintenance keeps the car looking new, interior maintenance ensures the car can travel hundreds of thousands of kilometers without major repairs and maintains the car in optimal technical condition. It mainly includes: lubrication system, fuel system, cooling system, braking system, and carburetor (injector) maintenance. Body refurbishment. Examples include diagnosing and treating deep scratches, repairing multi-material bumpers, fixing hard damage to wheel hubs (covers), refurbishing leather and synthetic materials, and refreshing engine colors. However, with the advancement of science and technology and the automotive industry, various advanced technologies, primarily computer-based, are widely applied in cars, making future cars increasingly intelligent. Thus, the content of car maintenance has been given new meaning.
