What is generally included in the first maintenance?

[Amir]

The first maintenance at a 4S shop includes the following aspects: changing the engine oil and oil filter, cleaning the air filter; checking the levels of various fluids to ensure they are normal, inspecting the generator belt and wiper blades for any damage; checking the tire pressure for normal levels, and examining the tires for uneven wear, bulges, or damage; inspecting the chassis, including: brake pads, brake discs, connecting rods, ball joints, CV joints, for any scratches, etc.; checking all switches in the vehicle; ensuring the lights are functioning properly. Estimated time: Completing all tasks takes approximately 2 hours. Items needed for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice, to be taken to the designated first maintenance facility for the vehicle's first maintenance. Important note: Schedule an appointment with the 4S shop in advance. The first maintenance refers to the initial maintenance after a new car has been driven, with the specific time varying by vehicle, generally after driving 1000 to 3000 kilometers. It is essential for the car to undergo the first maintenance promptly, neither in advance nor delayed. The completion of 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 by the vehicle. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance time: mileage and time. Whichever comes first serves as the standard. The following inspections and replacements must be completed during the first maintenance of a new car: changing the engine oil, cleaning the three filters, namely the oil filter, fuel filter, and air filter; checking the coolant level to ensure it is within the normal range; inspecting the vehicle's brake and clutch fluid levels; examining the power steering fluid level for normalcy and checking all fluid pipe connections for leaks; the technician should also check the generator, air conditioning, water pump, and the condition of the belts for aging and tension; inspecting the tire pressure and wear condition, inflating the tires as needed, or performing tire rotation if there is wear. When changing the engine oil, the oil filter must also be replaced. The selection of engine oil must refer to the "Vehicle Use and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people clean their cars themselves during holidays, washing the body with water and wiping it with a cloth. Here, it is important to remind that the interior of the car body should not be washed directly with water. If the floor mats are dirty, they can be cleaned with a vacuum cleaner or taken out, scrubbed with a brush and detergent, dried, and then placed back. There are many drainage holes under the rubber mats on the cabin floor. If water enters, it will not dry by air but will flow through the drainage holes to areas like the transmission, causing erosion and corrosion. A better approach is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the antifreeze and add the same brand of antifreeze from the beginning. Since different brands of antifreeze have significantly different chemical properties, the corrosion inhibitors in one brand may corrode those in another. Different brands of antifreeze use different corrosion inhibitors, so they should not be mixed to avoid unnecessary problems. Do not lubricate tire bolts and nuts: When the bolts on a moving car rust, they are often oiled to function properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricant to them, but this introduces unnecessary risks to safe driving. When the car is driven at high speeds, the bolts and nuts may loosen or even fall off, leading to driving failures. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: The starter of an EFI car is different from that of a conventional car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring smooth starting.
