Precautions for the running-in period of automatic transmission: 1. Maintain smooth starting and avoid sudden acceleration; 2. Do not keep the same gear for a long time or drive at low speed for a long time; 3. Warm up the car before starting, and turn on the air conditioner when the water temperature reaches 90 degrees Celsius after driving for a certain distance; 4. The vehicle should not be overloaded during driving; 5. Always pay attention to whether there is any reduction or leakage of fuel, lubricating oil, coolant and other fluids, and deal with it in time if found; 6. Choose a good road surface to avoid excessive vibration, impact or emergency braking; 7. Do not let the engine speed be too high; 8. The recommended fuel grade is posted on the inside of the fuel tank cap, and the oil model is marked on the oil filler plug. Use the fuel and oil recommended by the vehicle, and it is not advisable to use engine wear-resistant additives.
When I first got my automatic transmission car, I was especially careful during the break-in period, fearing I might damage the engine or transmission. It's recommended not to floor the accelerator or brake hard, as that can cause rapid internal part wear and shorten the car's lifespan. My approach was to maintain stable RPM, generally fluctuating between 2000 and 2500 RPM, avoiding frequent revving above 3000 RPM. Keep speed variations between 50 to 100 km/h, avoiding constant high or low speeds; for example, driving at 60 km/h in the city, then maintaining a steady 90 km/h on the highway. Also, avoid hauling heavy loads or overloading with passengers during the initial period to reduce engine strain. Check tire pressure and oil levels around 500 km, and change the oil promptly after completing the 1000 km break-in to remove metal debris. Driving patiently will make the new car run smoother and save money, otherwise, repair costs can be shockingly high.
