The concept of the break-in period for new cars originated from early limitations in automotive manufacturing processes, where vehicles did not achieve optimal performance right after production. A break-in period was necessary to allow various components to achieve their best working compatibility. Below are specific details about the break-in period: 1. With advancements in the automotive industry, manufacturing processes have significantly improved. Modern break-in periods differ from those in the past, as cars now undergo cold break-in treatments before leaving the factory. 2. During the initial usage of a new car, owners should keep the following key points in mind: (1) Avoid sudden acceleration, hard braking, overloading, and when going downhill, control the speed appropriately without abruptly using engine braking. (2) For manual transmission vehicles, anticipate gear shifts appropriately and avoid shifting at improper speeds. For automatic transmission vehicles, refrain from coasting in neutral or prolonged use of the S (Sport) mode. (3) Regularly check tire pressure, coolant level, brake fluid level, and engine oil level. (4) Regarding speed, do not exceed two-thirds of the vehicle's maximum speed, and keep engine RPM below 3000-3500 (requirements may vary among manufacturers). (5) After the break-in period ends, timely maintenance is essential. Typically, the completion of the first maintenance service signifies the end of the break-in period.
