What should be done during the break-in period of an automatic transmission car?

[DeRosalie]

When breaking in an automatic transmission car, there are five dos and five don'ts: First, use the correct oil; second, perform the initial maintenance; third, start in first gear; fourth, shift gears promptly; fifth, control the speed. The don'ts are: first, avoid high-speed driving; second, avoid running at full load; third, avoid long-distance trips; fourth, avoid emergency braking; fifth, avoid using it as a training car. The break-in period is crucial for a car. Just like an athlete's warm-up before a competition, the quality of a car's break-in directly affects its lifespan, safety, and fuel efficiency. The break-in period for a new car is generally between 2,500 to 3,000 kilometers. During this period, the engine speed should be kept around 2,500 RPM to ensure sufficient contact, friction, and adaptation of all components, which is the basic mileage required for proper break-in.
