The items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle's purchase invoice, to be taken to the designated first maintenance institution for the vehicle's first maintenance. The precautions are: make an appointment with the 4S store in advance. The first maintenance refers to the initial maintenance after the new car is driven, and the specific time varies from car to car, generally after driving 1,000 to 3,000 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 for 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. Whichever comes 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. Necessary time: 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 "Vehicle Use and Maintenance Manual", as different models specify different engine oil grades. Maintenance precautions: Do not rinse the inside of the car body with water: Many people will organize and clean the car by themselves during holidays, rinsing the body with water and scrubbing with a cloth. Here, it is necessary to remind that the inside of the car body does not need to be directly rinsed with water. If the floor mats are dirty, you can use a vacuum cleaner or take them out, brush and wash them with detergent, dry them, and then put them back. There are many through holes in the grooves under the rubber mats on the floor of the cab. After water enters, it will not dry by wind but will flow through the through holes to parts such as the gearbox 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 drain 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 this brings necessary risks to safe driving. When the car is running at high speed, the bolts and nuts are simply lifted or even dropped, causing driving failure. When promoting the EFI car, do not step on the accelerator: The promoter of the EFI 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, making the promoter promote smoothly.
