The 4S shop is maintained regularly, so don’t stay in the lounge anymore. Or you don’t know about these things?

Currently, I will go to the 4s store for 30,000 kilometers away for routine maintenance. The maintenance is given by the 4s when I buy a car.
I used to go to the 4s store for maintenance: eating, drinking, playing with my mobile phone, and watching TV.
Nowadays, I have learned the strict version of the forum. I decided to start this maintenance and visit the maintenance workshop in person, but I was an ordinary person and didn’t understand any technology. May I ask Yan Bian, do I need to pay attention to any details when maintaining the vehicle regularly? Are there any precautions?
Maintenance has been completed and the entire process is supervised. In the 4s shop, 1. The construction workers wanted to add water to the cooling tank, but I stopped them. 2. Suggest replacing the air conditioning filter (I already replaced it myself, but refused)3. Suggest replacing the brake fluid (I later bought it myself to replace it outside, but refused).
Share photos taken during maintenance. The main focus is on the oil certification of M264 920 engines in 4s stores. The manual recommends using oil, and the certification is 229.51/52/61/71. If you replace it in 4s, it will be 229.51(5W30). ps. In the future, you will need to wash it in 229.51(0W30). Share it with a car friend who also wants to buy his own oil for maintenance in the future, but I don’t know what to change with. Personal suggestions for reference.
