Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; vehicle owner's ID card; vehicle registration certificate; vehicle purchase invoice. Take these to the designated first maintenance facility for the vehicle's initial service. Important note: Schedule an appointment with the 4S store in advance. The first maintenance refers to the initial service after a new car has been driven. The specific timing varies by vehicle, generally around 5,000 kilometers or six months. It's crucial to attend the first maintenance on time, neither early nor late. Completing the first maintenance signifies the end of the vehicle's break-in period, allowing it to be driven under standard load and normal speed as required by the manufacturer. The first maintenance period is calculated from the date of vehicle pickup, with two indicators: mileage and time. Whichever comes first serves as the standard. First maintenance tasks include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels, inspecting the generator belt and wiper blades for damage, checking tire pressure, and examining tires for damage or bulges. Estimated time: Completing all tasks takes approximately 2 hours. The most critical aspect of a new car's first maintenance is changing the engine oil and oil filter. When replacing the oil, the oil filter must also be changed. The choice of engine oil should refer to the "Vehicle User Maintenance Manual," as different vehicle models require different oil specifications. 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. 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 remove them to scrub with a brush and detergent, then dry before replacing. The rubber mats under the driver's floor have many drainage holes. Water entering these areas won't dry naturally but will flow through the holes, potentially causing corrosion in the transmission and other parts. The best practice is to vacuum clean and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: If the car's antifreeze level is low, it's advisable to drain the existing antifreeze and refill with the same brand. Different brands of antifreeze have varying chemical properties, and mixing them can lead to corrosion due to incompatible additives. Always use the same brand to avoid unnecessary issues. Do not lubricate wheel bolts and nuts: When bolts on a moving car rust, they are often oiled to restore functionality. However, applying lubricant to wheel bolts and nuts can pose safety risks. At high speeds, lubricated bolts and nuts may loosen or even fall off, leading to driving hazards. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: EFI vehicles differ from conventional cars, as their fuel injection control system automatically adjusts fuel supply based on engine temperature and operating conditions, ensuring smooth starting without pressing the accelerator.
