What are the items included in a car's first maintenance?

[LaPatrick]

During a car's first maintenance, the tire tread and pressure are checked, small stones on the tires are removed, and a four-wheel alignment check is performed. Below are the specific items included in a car's first maintenance: 1. Inspect and tighten all mechanical connection nuts in the engine compartment and throughout the vehicle; check the tire tread and pressure, remove small stones from the tires, and perform a four-wheel alignment check. 2. Replace the engine oil and oil filter. Based on the condition of the replaced oil, assess whether the engine's machining precision is good. If the oil is not very black, flows well, and is not too thick, it indicates good machining precision. If the drained oil is very black and thick, it suggests significant wear on the mechanical metal surfaces of the engine and transmission during the break-in period. Check whether the power steering fluid level meets the specified requirements and inspect all oil pipe interfaces in the system for leaks. Check whether the car's coolant level is within the specified range.
