[OGiselle]

New cars should undergo their first maintenance within 3 to 5 months, with the initial maintenance mileage typically ranging from 3,000 to 5,000 kilometers, whichever comes first. The specific timing can be checked in the vehicle manual. Different brands and models of cars are equipped with different engines. Some engines use special technologies and have strict requirements for oil, while others are made of special materials with high precision, resulting in relatively less wear. Therefore, the specified time and mileage for the first maintenance vary. The main items for the first maintenance include: 1. Changing the engine oil and oil filter. 2. Checking the operation of the braking system. 3. Tightening the bolts of various systems. 4. Inspecting and adjusting the drive belt. 5. Checking and adjusting tire balance and alignment. 6. Inspecting and replenishing various fluids. 7. Checking the operation of components such as lights, the battery, and shock absorbers.
