First of all, you need to know some common sense about repairing cars in 4s shops:

1. When the car drives to the 4s shop, a staff member will come forward to serve the reception. They all hold folders with car maintenance sheets on them.

2. It is necessary to fill in the car number plate, car model, parts of the car that need to be maintained/repaired, and the fuel gauge indicators of the car at that time on the car maintenance list;

3. After the owner tells the staff that the auto parts need to be revised, the staff will fill in the auto maintenance document, and then ask the owner to sign the document for confirmation. One copy is kept by the owner and the other is kept by the 4s shop after the car is repaired.

4. After confirmation, go to the finance department to hand it in.

Then, wait for the 4s shop to notify the maintenance to be completed, and pick up the car with the car maintenance list. If there is no maintenance bill, you can also pick up the car with the owner's ID card.
