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: Schedule an appointment with the 4S store in advance. 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 approximately half a year. It is essential to attend the first maintenance promptly, neither in advance nor delayed. The completion of the first maintenance signifies the end of the vehicle's break-in period, allowing it to be driven under standard loads and normal speeds as required. The timing for the first maintenance is calculated from the date of vehicle pickup, with two indicator values: mileage and time. Whichever comes first serves as the standard. First maintenance tasks include: oil change, oil filter replacement, air filter cleaning, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, verifying tire pressure is normal, and examining tires for damage or bulges, etc. Estimated time required: Approximately 2 hours to complete all tasks. The most crucial aspects of a new car's first maintenance are the oil and oil filter replacement. When changing the oil, the oil filter must also be replaced simultaneously. The choice of oil must refer to the "Vehicle Usage 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. Here, it's important to note that the car's interior should not be directly washed with water. If 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 driver's floor. Water entering these areas won't dry naturally but will flow through the holes to components like the transmission, 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: When the car's antifreeze is low, it's advisable to drain the existing antifreeze and refill with the same brand from the start. Different brands of antifreeze have varying chemical properties, and the corrosion inhibitors in one may react adversely with those in another. To avoid unnecessary issues, never mix different brands of antifreeze. Do not lubricate wheel 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 wheel bolts and nuts to prevent rust, inadvertently introducing safety risks. At high speeds, lubricated bolts and nuts may loosen or even fall off, leading to driving failures. Electronic fuel injection vehicles do not require pressing the accelerator when starting: The starter of an electronic fuel injection vehicle differs from conventional cars. Its fuel injection control system can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
