What Documents Are Needed for the First Maintenance at a 4S Shop?

[MacMartin]

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: 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 occurring after driving 1,000 to 3,000 kilometers. It's crucial to attend the first maintenance on time—neither early nor delayed. Completing the first maintenance signifies the end of the car's break-in period, allowing it to be driven under standard loads and normal speeds as required. The first maintenance timeline is calculated from the date of vehicle pickup, with two indicators: mileage and time. Whichever comes first serves as the standard. Free services during the first maintenance generally include: engine oil change, tightening chassis screws, checking tire pressure, inspecting all vehicle fluids, checking all lights, cleaning the air filter and cabin air filter, engine dust removal, and topping up windshield washer fluid and coolant. Oil change: Pay attention to the oil type and brand, ensuring the oil container is original and unopened. It's advisable to take a photo with your phone for future reference regarding engine performance post-maintenance. Tightening car screws: Many vehicles leave the factory with screws not fully tightened to account for the break-in period. During the first maintenance, after the break-in is mostly complete, the mechanic will tighten all connecting screws to the torque specified in the manual. Tire pressure: Standard tire pressure is around 2.2~2.6 bar. Overinflation increases tire wear and may cause blowouts, while underinflation raises fuel consumption and ride discomfort. Generally, tire pressure can be slightly lower in summer and slightly higher in winter. Fluid inspection: Includes a comprehensive check of engine oil, power steering fluid, transmission fluid, and brake fluid. Light inspection: Covers headlight alignment, brightness, bulb condition, and proper functioning of turn signals, followed by checking the taillights. Air filter and AC check: Assesses AC cooling/heating efficiency and airflow strength. Engine inspection: Focuses on wiring, hoses, chain or belt wear, unusual odors, and oil leaks. Topping up windshield washer fluid and coolant: Windshield washer fluid is specialized glass water that prevents rust and freezing in winter. Time required for first maintenance: Completing all tasks takes about 2 hours. The most critical aspect of the first maintenance is changing the engine oil and oil filter. The oil filter must be replaced alongside the oil, and the oil selection should follow the Vehicle User and Maintenance Manual, as different models require different oil specifications. Maintenance precautions: Avoid washing the interior with water: Many people clean their cars during holidays, including hosing down the interior and wiping it with a cloth. Note that the interior should not be directly washed with water. If floor mats are dirty, use a vacuum or remove them to scrub with detergent, dry, and reinstall. The cabin floor has multiple drainage holes under rubber mats; water entering won't dry but will flow to components like the transmission, causing corrosion. Instead, vacuum and wipe to prevent water accumulation. Do not mix different brands of antifreeze: If the antifreeze level is low, drain it completely and refill with the same brand. Different brands have varying chemical properties, and mixing them may cause corrosion due to incompatible additives. Avoid lubricating wheel bolts and nuts: While lubricating rusty bolts may seem helpful, applying grease to wheel bolts/nuts poses safety risks. At high speeds, lubricated bolts may loosen or detach, leading to driving hazards. No need to press the accelerator when starting fuel-injected cars: Unlike conventional cars, fuel-injected vehicles' control systems automatically adjust fuel supply based on engine temperature and conditions, ensuring smooth starts.
