What should be noted for the first maintenance of Volkswagen cars?

[KhloeLynn]

Items to bring for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice, and take the vehicle to the designated first maintenance facility. 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, generally after driving 3,000~5,000 kilometers or about half a year. It is essential to attend the first maintenance on time, neither early 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 of 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. The 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. Required time: 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 oil, the oil filter must also be replaced. The choice of 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 themselves during holidays, washing the body with water and scrubbing 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, they can be vacuumed or taken out, scrubbed with a brush and detergent, dried, and then put back. There are many holes under the rubber mats on the floor of the driver's compartment. Water entering these holes will not dry out but will flow through the holes to areas 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 beginning. Since antifreeze brands differ, their chemical properties vary greatly. Various functional additives can 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 the bolts on a moving car rust, they are often oiled to function properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricant to them, but this introduces potential safety hazards. When the car is driven at high speed, the bolts and nuts can easily loosen or even fall off, leading to driving malfunctions. Do not press the accelerator when starting an EFI car: The starter of an EFI car is different 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.
