Items required for the first maintenance include: driver's license; motor 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 facility for the vehicle's initial service. Important note: Make an appointment with the 4S store in advance. The first maintenance refers to the initial service after the new car has been driven, with the specific timing varying by vehicle, generally after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance promptly, neither in advance nor delayed. The completion of the first maintenance signifies the end of the vehicle's break-in period, allowing it to be driven according to the standard load and normal speed requirements. The timing for the first maintenance is calculated based on the vehicle pickup date, with two indicator values: mileage and time. Whichever comes first serves as the standard. First maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges, etc. Required time: Approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is the replacement of engine oil and the oil filter. When changing the oil, the oil filter must also be replaced simultaneously. The selection of engine oil must refer to the "Vehicle Use and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people tend to organize and clean their cars during holidays, washing the body with water and wiping it with a cloth. It's important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, they can be vacuumed or taken out, brushed with detergent, dried, and then put back. There are many drainage holes under the rubber mats on the floor of the driver's compartment. Water entering these areas does not dry by wind but flows through the holes to parts like the gearbox, causing erosion and corrosion. A better approach is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the antifreeze and add the same brand from the start. Since antifreeze brands differ, their chemical properties vary significantly. Various functional additives may corrode others. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. To prevent bolts and nuts on wheels from rusting, some apply lubricating oil, which can pose safety risks. When the car is driven at high speeds, bolts and nuts may loosen or even fall off, leading to driving malfunctions. Do not press the accelerator when starting an EFI car: The starter of an EFI (Electronic Fuel Injection) car differs from that of a conventional car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
