Here are the methods for breaking in a manual-automatic transmission car: 1. Warm up the car before starting: After the car has been parked overnight, the engine oil flows back into the oil pan. After starting the car, it takes some time for the oil to fully lubricate all components of the engine from the oil pan. If you drive immediately after starting, the internal components of the engine may not be fully lubricated, leading to abnormal wear. Simply warm up the car before driving, and wait until the idle speed stabilizes before moving off. 2. Speed control during the break-in period: The speed during the break-in period should be increased gradually. For the first 500 kilometers, try to maintain a speed of 60-70 km/h, with the engine speed not exceeding 2,200 rpm. From 500 to 1,000 kilometers, the speed can be increased to 90-100 km/h, with the engine speed generally kept below 2,500 rpm. After 1,000 kilometers, the speed can be increased to below 120 km/h, with the engine speed not exceeding 3,000 rpm. 3. Gear control: During the break-in period, it is important to control the gear shifts properly in a manual-automatic transmission. Avoid suddenly shifting into P or R gear while driving, as this can cause severe impact on the transmission and may even damage it. When shifting into reverse, ensure the car is completely stopped before doing so. Additionally, practice using the manual mode in areas with good road conditions. 4. Avoid coasting in N gear: Do not coast in N gear while driving. When in N gear, the transmission's power pump stops working, leading to abnormal wear due to lack of coolant and lubrication, which shortens the transmission's lifespan and increases fuel consumption. 5. Avoid emergency braking: Try to avoid emergency braking during the break-in period. Emergency braking can cause impact on the car's braking system. Since the car's components are not fully broken in during this period, frequent emergency braking is detrimental to the break-in process and can also damage the car's chassis. 6. Generally, do not change the engine oil prematurely: The oil used during the break-in period is usually a specialized lubricant with low viscosity, excellent heat dissipation, cleaning, and antioxidant properties. Some oils even contain grinding agents that aid in the break-in process. Changing the oil too early can hinder the break-in process.
