What should be paid attention to when doing the first car maintenance?

[StEmmanuel]

Driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle's purchase invoice are all the things needed for the first car maintenance. The first maintenance is carried out after driving about 5,000 kilometers, which refers to the first maintenance after the vehicle is driven. The precautions are: make an appointment with the 4S shop in advance. The first maintenance refers to the first maintenance after the new car is driven, and the specific time varies from car to car. The first maintenance is carried out after driving about 5,000 kilometers. The car needs to participate in the first maintenance in time, neither in advance nor delayed. The realization of the first maintenance marks that the running-in period of the car has now ended, and it can be driven according to the standard load and normal speed required by the car. The time of the first car insurance is calculated according to the date of picking up the car. There are two indicator values for the first maintenance time: mileage and time. See which comes first, the first is the standard. The first maintenance items include: changing the engine oil, oil filter, cleaning the air filter, checking whether various oil levels are normal, checking whether the generator belt and wiper blades are damaged, checking whether the tire pressure is normal, checking whether the tires are damaged, bulging, etc. Time required: It takes about 2 hours to complete all the work. The most important thing for the first maintenance of a new car is to change the engine oil and oil filter. When changing the engine oil, the oil filter element must be replaced together. When choosing the engine oil, you must refer to the "Model Use and Maintenance Manual", and different models have different regulations on the engine oil label. Maintenance precautions: Do not rinse the inside of the car body with water: Many people will arrange and clean the car by themselves during the holidays, and rinse with water and scrub with a cloth. Here, it needs to be reminded that the inside of the car body does not need to be rinsed directly with water. If the floor mat is dirty, you can use a vacuum cleaner, or take it out, brush and wash it with detergent, dry it, and then put it back. There are many through holes in the grooves under the rubber mats on the floor of the cab. After the water enters, it will not dry by wind, but will flow to the gearbox and other parts through the through holes for erosion and corrosion. The good practice is to clean with a vacuum cleaner and then scrub with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is in short supply, it is recommended that you release the antifreeze as soon as possible and add the same brand of antifreeze from the beginning. Because the brands of antifreeze are different, their chemical functions are also very different. Various functional preservatives will corrode other functional preservatives. Different brands of antifreeze use different preservatives. Do not mix them to avoid unnecessary trouble. Do not lubricate the tire bolts and nuts: When the bolts of the running car are rusty, they are usually oiled so that they can work normally again. In order to prevent the bolts and nuts on the wheels from rusting, some people apply lubricating oil to the bolts and nuts, but it brings necessary risks to safe driving. When the car is running at high speed, the bolts and nuts are simply lifted or even dropped, resulting in driving failure. When the fuel injection car is promoted, there is no need to step on the accelerator: The promoter of the fuel injection car is different from that of ordinary cars. Its fuel injection control device can actively adjust the fuel supply according to the temperature and working conditions of the promoter, so that the promoter can be promoted smoothly.
