What does the break-in period of a car mean?

[MacElaina]

The break-in period of a car refers to the initial driving period after a new car leaves the factory, during which the engine components wear in smoothly. The first maintenance cycle for a car is usually around 5,000 kilometers. Precautions during the car's break-in period include: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine RPM get too high; 2. Before starting, ensure the coolant temperature reaches at least 50 degrees Celsius, start in low gear, and shift to high gear after 1 kilometer; 3. Shift gears promptly while driving, avoid prolonged use of a single gear, and do not use high gear at low speeds or low gear at high speeds; 4. Choose good road conditions to avoid excessive vibration or impact, and disengage the clutch before braking; 5. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives.
