Items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle's purchase invoice. Take these to the designated first maintenance service center for the vehicle. 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. The specific time varies by vehicle, usually after driving 1000 to 3000 kilometers. It's 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 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 items include: oil change, oil filter replacement, cleaning the air filter, checking various fluid levels, inspecting the generator belt and wiper blades for damage, checking tire pressure and for any damage or bulges. Estimated time: Approximately 2 hours to complete all tasks. The most critical part of the first maintenance for a new car is changing the 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 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's 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 to brush with detergent, dry them, and then put them back. There are many holes under the rubber mats on the driver's floor. If water enters, it won't dry but will flow through these holes to areas like the gearbox, causing erosion and corrosion. The best practice is to clean with a vacuum and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: If the car's antifreeze is low, it's recommended to drain the existing antifreeze and add the same brand from the start. Different brands of antifreeze have significantly different chemical properties. Various functional additives can corrode others. Different brands use different additives, so they should not be mixed to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. To prevent rust on wheel bolts and nuts, some people apply lubricant, which can pose a safety risk. At high speeds, bolts and nuts can loosen or even fall off, leading to driving malfunctions.
