Documents required for the first maintenance include: driver's license; maintenance manual; vehicle registration certificate; 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. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial maintenance after the new car has been driven, with the specific time varying by 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 the end of the car's running-in period, and it can now be driven according to the standard load and normal speed required by the car. The time for the first maintenance is calculated based on the date of picking up the car. There are two indicator values for the first maintenance time: mileage and time. Whichever indicator is met first will be the basis. First maintenance items include: oil change, oil filter replacement, cleaning of the air filter, checking whether various oil levels are normal, checking the generator belt, whether the wiper blades are damaged, checking whether the tire pressure is normal, checking whether the tires are damaged or bulging, etc. Time required: It takes about 2 hours to complete all the work. The most important part of the first maintenance for a new car is the oil and oil filter replacement. When changing the oil, the oil filter must be replaced together, and the oil selection must refer to the "Vehicle Use and Maintenance Manual", as different car models specify different oil grades. Maintenance precautions: Do not rinse the inside of the car body with water: Many people will organize and clean their cars 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 cockpit. After water enters, it will not dry by wind but will flow through the through holes to parts such as the gearbox, causing 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 car's antifreeze 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 chemical functions of antifreeze vary greatly by brand. 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 on a running car rust, it is common to oil them so they can work properly again. 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 driving at high speed, the bolts and nuts are simply lifted or even dropped, leading to 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 smoothly promoted.
