What are the procedures and precautions for new car inspection at the testing site?

[Dakota]

The procedures and precautions for new car inspection at the testing site are as follows: 1. First, visually inspect the body paint surface to check for scratches, spots, dents, and wear. Observe the paint under sufficient sunlight to see if there is any color difference. Open the doors and adjust them to different angles to allow light to shine from various directions, checking if the sheet metal is smooth and if there are any signs of repair. 2. Check the vehicle identification plate, which is located on the side of the driver's door or in the engine compartment. Pay attention to whether the manufacturing date is too far in the past. If it exceeds six months, the car is likely a stock vehicle or a test drive car. Also, ensure that the information on the identification plate matches that on the vehicle certification. 3. Inspect the windshield. The numbers represent the most recent production year, and the dots indicate the production month. If the dots are on the left side of the number, it means the windshield was produced in the first half of the year. Subtract the number of black dots from 7 to get the specific year. If the dots are on the right side, it means the windshield was produced in the second half of the year. Subtract the number of black dots from 13 to get the specific year. If the windshield's production date is far from the car's production date—by a year or more—it is likely that the windshield has been replaced. 4. Open the engine hood and check if the engine compartment is clean. If the car has been stored for a long time or used, some areas may have noticeable dust or stains. Also, check if the engine oil level is sufficient and if other fluid levels are within the acceptable range. 5. Open the doors and check if they open and close smoothly and flexibly, with no noise from the hinges. Ensure the gaps between the doors and the front and rear bumpers are consistent and that the doors can be closed in one motion. 6. Check the production date of the tires. Since tires are purchased separately, their production date will naturally differ from the car's production date, which is not a major concern. However, if the tire production date is significantly older than the car's delivery date, it is worth noting. 7. Test the basic functions of the car, such as whether the windows roll up and down properly, the air conditioning cools, the air vents emit any unusual odors, the dashboard functions operate normally, the windshield wipers work, the lights turn on correctly, and the sunroof opens and closes smoothly. 8. Test drive the car if allowed. Observe whether the engine idles smoothly, the steering wheel vibrates noticeably, the front and rear seats shake significantly, or if there is any unusual noise inside the car.
