What materials are needed for the first maintenance?

[LucyMarie]

The items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice. Bring these 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 time 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 marks the end of the car's break-in period, allowing it to be driven under standard loads and normal speeds as required by the vehicle. 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 will be 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. 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 engine oil, the oil filter must also be replaced. 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 their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior of the car body should not be directly rinsed with water. If the floor mats are dirty, use a vacuum cleaner or take them out, scrub them with a brush and 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 transmission, 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 beginning. 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 the bolts on a car become rusty during driving, they are often oiled to function properly again. To prevent rust on wheel bolts and nuts, some people apply lubricant, but this poses a safety risk. When the car is driven at high speed, the bolts and nuts may loosen or even fall off, leading to driving malfunctions. Do not press the accelerator when starting an electronic fuel injection car: 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.
