Precautions for the break-in period of an automatic transmission new car are: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine speed become too high; 2. Before starting, the water temperature should reach above 50 degrees Celsius; 3. Start in a low gear, shift to a higher gear after 1 kilometer, and keep the water temperature between 80 and 90 degrees Celsius while driving; 4. Choose good road conditions to avoid excessive vibration, impact, or emergency braking. Before braking, disengage the clutch first; 5. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives. The steps to start an automatic transmission car are: 1. Insert the key into the ignition and turn it to the second position (power mode), wait for the system self-check to complete; 2. Shift the gear lever from P to N; 3. Release the brake and start the car's engine; 4. Press the brake pedal with your foot, shift the gear lever from N to D, release the brake, and press the accelerator to start.
The break-in period for a new car is particularly important. When I bought my automatic transmission car last year, I didn’t pay much attention to it, and the engine ended up making strange noises. Later, I learned that new car parts need time to adapt gradually. Don’t drive too fast—it’s recommended to keep the speed under 100 km/h, especially within the first 1,000 kilometers. Avoid sudden acceleration and hard braking; drive smoothly instead. Also, avoid maintaining a constant speed for long periods on the highway—vary your speed, such as driving in stop-and-go city traffic or occasionally taking suburban routes. Don’t fill the fuel tank to the brim to reduce weight and lessen the engine’s load. Regularly check the engine oil and coolant—I personally check every 500 kilometers to ensure the levels are normal. Also, test the brakes more often when the car is new to get a feel for them, and avoid slamming them. Be sure to read the manufacturer’s manual, as it contains specific recommendations. A proper break-in can improve fuel efficiency and extend the car’s lifespan.
