What is the break-in period for a new car in kilometers, and what should be noted?

[OscarDella]

New cars generally have a break-in period of 3,000 kilometers. The following aspects should be noted for new cars: Engine: The engine speed should not be too high, preferably not exceeding 3,000 RPM, with an ideal speed range of 60-90 km/h. Warm-up: There should be a warm-up process during cold starts; wait for the water temperature to change before driving, typically around 2-3 minutes. In summer when temperatures are high, a warm-up of about 1 minute is sufficient. Driving duration: Avoid sudden acceleration and braking, and try to maintain a steady speed. During the break-in period, the maximum speed should not exceed 120 km/h, but long-term low-speed driving should also be avoided. Pay attention to gear changes. Maintenance: Avoid overloading the car with passengers or cargo. Follow the manufacturer or 4S shop's requirements to promptly perform the first maintenance.
