Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle 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 shop in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific timing varying by vehicle, typically after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance on time, neither early nor delayed. The completion of the first maintenance signifies the end of the car's break-in period, allowing the vehicle to be driven under standard load and normal speed as required. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first serves as the standard. First maintenance tasks 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. Required time: completing all tasks takes approximately 2 hours. The most critical aspect of a new car's first maintenance is changing the engine oil and oil filter. When replacing the engine oil, the oil filter must also be replaced simultaneously. The selection of engine oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean and organize their cars during holidays, washing the body with water and wiping it with a cloth. Here, it is important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush and wash with detergent, dry them, and then put them back. There are many drainage holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry naturally but will flow through the holes to areas like the gearbox, causing erosion and corrosion. The best practice 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 people apply lubricant to them, which can pose safety risks. When the car is driven at high speeds, the bolts and nuts may loosen or even fall off, leading to driving malfunctions. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: The starter of an EFI car differs from that of a conventional car, as its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
