Items required for the first maintenance include: driver's license; vehicle registration book; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle 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 after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance promptly—neither too early nor too late. Completing the first maintenance signifies the end of the car's break-in period, allowing it to be driven at standard loads and normal speeds as required by the manufacturer. The first maintenance period is calculated from the date of vehicle pickup. There are two criteria for the first maintenance: mileage and time. Whichever comes first serves as the standard. First maintenance tasks include: changing 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 crucial aspect of the first maintenance is changing the engine oil and oil filter. When replacing the oil, the oil filter must also be replaced. The choice of oil should refer to the "Vehicle User and Maintenance Manual," as different models require different oil specifications. Summer Maintenance Tips: Choose high-viscosity oil for summer. High temperatures can cause engine coolant to heat up quickly, leading to reduced oil viscosity, oxidation, and darkening. Prevent battery leakage. High temperatures can cause the battery's insulation layer to age and oxidize, leading to unstable voltage and early leakage. Prevent wiper blades from softening or deforming. Wiper blades exposed to sunlight for prolonged periods can overheat, soften, and deform, impairing their ability to clear rain and potentially damaging the windshield. Perform regular air conditioning checks and maintenance. Frequent use in hot weather requires cleaning the condenser to prevent debris buildup, which can reduce cooling efficiency. Monitor tire temperature and pressure. High temperatures increase tire friction, causing rapid temperature rise and slow heat dissipation, leading to higher pressure and increased risk of blowouts. Maintenance Precautions: Avoid washing the interior with water: Many people clean their cars by spraying water and wiping with a cloth. However, the interior should not be directly washed with water. Use a vacuum cleaner for dirty floor mats, or remove them, scrub with detergent, dry, and reinstall. Water entering the cabin floor's drainage holes can lead to corrosion in components like the transmission. Instead, use a vacuum and a damp cloth to avoid water accumulation. Do not mix different brands of antifreeze: If the antifreeze level is low, drain and refill it with the same brand. Different brands have varying chemical compositions, and mixing them can cause corrosion due to incompatible additives. Do not lubricate wheel bolts and nuts: While lubricating rusty bolts may seem helpful, applying grease to wheel bolts can be hazardous. At high speeds, lubricated bolts may loosen or fall out, causing driving issues. Avoid pressing the accelerator when starting an EFI (electronic fuel injection) vehicle: Unlike traditional engines, EFI systems automatically adjust fuel supply based on engine temperature and conditions, ensuring smooth starts without throttle input.
