Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle registration book, vehicle purchase invoice, to perform the first maintenance at the designated maintenance facility. 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 specific timing varying by vehicle, generally after driving 1,000 to 3,000 kilometers or three months. It's essential to attend the first maintenance promptly, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard load and normal speed as required by the vehicle. The timing for the first insurance 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 items include: changing engine oil and oil filter, cleaning the air filter, checking various oil levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and inspecting tires for damage or bulging, etc. Time required: Completing all tasks takes approximately 2 hours. The most crucial aspect of the first maintenance for a new car is changing the engine oil and oil filter. When changing the engine oil, the oil filter must also be replaced simultaneously. The choice of engine oil must refer to the "Vehicle Use 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 their cars during holidays, washing the body with water and wiping with a cloth. Here, 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, a vacuum cleaner can be used, or they can be taken out, brushed with detergent, dried, and then placed back. There are many holes under the rubber mats on the cabin floor. If water enters, it won't dry naturally but will flow through these holes to areas like the gearbox, causing erosion and corrosion. A better approach is to clean with a vacuum and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is insufficient, it's recommended to drain the antifreeze and add the same brand from the beginning. Since different brands of antifreeze have vastly different chemical properties, mixing them can lead to corrosion among various functional additives. Different brands of antifreeze use different corrosion inhibitors, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, it's common to oil them to restore functionality. However, some people apply lubricant to the bolts and nuts to prevent rust, which can pose necessary risks to safe driving. At high speeds, bolts and nuts can easily loosen or even fall off, leading to driving malfunctions. Electronic fuel injection cars do not require stepping on the accelerator when starting: The starter of an electronic fuel injection car differs from that of a regular 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.
