What is generally included in the first maintenance?

[MacCharles]

The first maintenance at a 4S shop includes the following aspects: changing the engine oil and oil filter, cleaning the air filter; checking whether the levels of various fluids are normal, inspecting the generator belt and wiper blades for any damage; checking whether the tire pressure is normal and if there is any uneven wear, bulging, or damage to the tires; inspecting the chassis, including the brake pads, brake discs, connecting rods, ball joints, CV joints, and any scratches; checking all the switches in the vehicle; and ensuring that the lights are functioning properly. Estimated time: Completing all the work takes about 2 hours. Items to bring for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; and the vehicle purchase invoice. The first maintenance should be done at the designated maintenance facility. Note: It is advisable to make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, and the specific time varies by vehicle, generally after driving 1,000 to 3,000 kilometers. The car must undergo the first maintenance promptly, neither earlier nor later. The completion of the first maintenance indicates that the car's break-in period has ended, and it can now be driven according to the standard load and normal speed required by the vehicle. The timing of the first maintenance is calculated from the date of vehicle pickup. There are two indicators for the first maintenance: mileage and time. Whichever comes first is the standard. The following inspections and replacements must be completed during the first maintenance of a new car: changing the engine oil and cleaning the three filters (oil filter, fuel filter, and air filter); checking whether the coolant level is normal; inspecting the brake and clutch fluid levels; checking the power steering fluid level and whether there are any leaks at the fluid pipe connections; inspecting the condition of the generator, air conditioning, water pump, and belts for aging and tension; checking the tire pressure and wear condition, inflating the tires, or performing tire rotation if there is wear. When changing the engine oil, the oil filter must also be replaced. The choice of engine oil must refer to the "Vehicle User Maintenance Manual," as different vehicle models require different oil specifications. Maintenance precautions: Do not wash the interior of the car with water: Many people clean their cars themselves during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior of the car should not be washed directly with water. If the floor mats are dirty, use a vacuum cleaner or take them out, scrub them with a brush and detergent, dry them, and then put them back. There are many drainage holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry naturally but will flow through the holes to areas like the gearbox, causing erosion and corrosion. The best practice 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 existing antifreeze and refill it with the same brand. Since different brands of antifreeze have different chemical properties, mixing them can cause corrosion between the different types of inhibitors. Different brands of antifreeze use different inhibitors, so they should not be mixed to avoid unnecessary problems. Do not lubricate tire bolts and nuts: When the bolts on a car become rusty, some people apply oil to make them work smoothly again. However, lubricating the bolts and nuts on the wheels can pose a safety risk. When the car is driven at high speeds, the 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: The starter of an EFI car is different from that of a conventional car. The fuel injection control system can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
