Introduction to the break-in period for a new car: The break-in period for a new car lasts until the first maintenance service. Most vehicles require the first maintenance service at either 5,000 kilometers or 6 months, so the break-in period for most cars is 6 months. During the break-in period, there is no need to worry about the vehicle speed, but it is important to pay attention to the engine RPM. Avoid running the engine at excessively high RPMs during the break-in period, as this can increase engine wear. Below is an introduction to the first maintenance service: 1. Check whether the tire pressure is normal and inspect the tires for uneven wear, bulges, or damage. 2. Inspect the vehicle chassis, including checking the brake pads, brake discs, connecting rods, ball joints, and CV joints for any scratches. 3. Replace the engine oil and oil filter, clean the air filter, and check whether the generator belt and wiper blades are damaged. 4. Check the levels of various fluids to ensure they are normal. 5. Inspect all switches and lights in the vehicle to ensure they are functioning properly.
When I first got my new car, I specifically asked the veteran technician from the manufacturer. The first 500 kilometers during the break-in period are the most critical. It's best to keep the speed below 80 km/h and avoid stomping on the accelerator to prevent the RPM from exceeding 3000. Remember to avoid prolonged constant-speed highway driving—change lanes occasionally to give the transmission some exercise. Don't overload the trunk, and be gentle with the brakes to allow the engine and drivetrain to properly sync. Only after the first maintenance service should you gradually increase the speed to 120 km/h. With advanced manufacturing techniques nowadays, the break-in period has shortened to 1,000–1,500 kilometers, but you still need to follow these precautions—after all, it affects the car's lifespan.
