Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; and the vehicle's purchase invoice. Take these to the designated first maintenance facility for the 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. The specific timing varies by vehicle, typically around 5,000 kilometers or six months. It's essential to attend the first maintenance on time—neither early nor late. Completing the first maintenance signifies the end of the car's break-in period, allowing it to be driven under standard load and normal speeds as required. The first maintenance time is calculated based on the vehicle pickup date. There are two indicator values for the first maintenance: mileage and time. Whichever comes first will be the standard. 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 and condition for damage or bulges, etc. Estimated 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 Usage and Maintenance Manual, as different models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car 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 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 drainage holes under the rubber mats on the cabin floor. Water entering these areas won't dry naturally but will flow through the holes to parts like the gearbox, causing erosion and corrosion. The best practice is to vacuum clean 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 recommended to drain the existing antifreeze and refill it with the same brand from the start. Different brands of antifreeze have varying chemical properties, and mixing them can cause corrosion between different types of inhibitors. Avoid mixing antifreeze brands to prevent unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function again. Some people apply lubricant to wheel bolts and nuts to prevent rust, but this can pose safety risks. At high speeds, bolts and nuts may loosen or even fall off, leading to driving malfunctions. No need to press the accelerator when starting an EFI car: The starter of an EFI (Electronic Fuel Injection) car differs from that of a conventional car. Its fuel injection control system can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
