According to the car maintenance instructions, do I have to go to the 4S shop?

During the warranty period of the vehicle, you must go to the 4S shop to do it. If you don't do it according to the time specified in the maintenance manual, the 4S shop can cancel the vehicle warranty on the grounds that there is no regular maintenance, and you can enjoy the vehicle warranty. Damaged parts can be replaced free of charge.

The maintenance content must be carried out according to the items in the maintenance manual. 4S stores usually add items other than these items, such as: 1 10,000 kilometers to clean the engine oil circuit and throttle body, and it usually takes 60,000 kilometers to clean the oil circuit.

Extended data:

Shiny car paint often inadvertently reveals scratches, so it is not cost-effective to push sand wax to the car beauty shop. The method of grinding with toothpaste can remove minor scratches and the effect is good.

Rinse the scratch with clear water first, then take a clean cloth or towel and dip a little toothpaste in it and rub it gently and repeatedly. After the scratches disappear or weaken, dry them with a wet towel. There is a simple reason. Toothpaste itself is an abrasive for cleaning teeth, which has no harm to human body or car paint.

After the rain, the door sealing strip was wet and sticky with paint, and the door was uneven and creaked. You can put a handful of talcum powder on the rubber seam in the door, and the symptoms will disappear. The door can be opened and closed freely without any noise.
