When a vehicle is exposed to the air for extended periods, the pores on the paint surface can absorb various substances. Below is relevant information about car maintenance: 1. First Maintenance: Some manufacturers determine the first maintenance based on time or mileage. The exact timing should be referenced in the vehicle's user manual or warranty manual. The first maintenance is crucial and typically free, so it's important not to miss it, as this could affect the car's third maintenance. 2. Maintenance Items: Key car maintenance tasks include replacing engine oil, oil filters, transmission fluid, spark plugs, cabin air filters, engine air filters, brake fluid, etc. However, not all items need replacement during every maintenance session; this depends on their service life. Additionally, maintenance involves inspecting and servicing dozens of components across multiple systems, including the engine, transmission, air conditioning, steering, braking, suspension, body, and tires.
