The first maintenance of a vehicle primarily involves changing the engine oil and oil filter, along with a comprehensive inspection of the vehicle. This includes checking all lights, all fluid levels, the functionality of the electrical system, tires, chassis components, and the engine and transmission to ensure everything is working properly. Additionally, a professional diagnostic device is used to perform a computer scan of the entire vehicle, and the maintenance reminder is reset. Below are some related details: 1. Break-in period introduction: The period from when a new car is first driven until its first maintenance is called the break-in period. During this time, because the gears of the engine, transmission, etc., have not yet fully worn in smoothly, it is generally advised not to drive too fast, and absolutely not to exceed 100 km/h. 2. Maintenance intervals: The timing for minor maintenance depends on the effective time or mileage of the engine oil and oil filter used.

For the first maintenance of a new car, I recommend not missing the scheduled time, usually around 5,000 kilometers or six months. The main tasks are two major parts: changing the engine oil and oil filter, as the new engine will produce debris after breaking in, and not replacing them can affect performance. Additionally, there are quite a few inspection items. The mechanic will check if there are any scratches or looseness in the chassis, the condition of tire wear, and whether the tire pressure is normal. Various fluids also need to be checked, such as whether the brake fluid is sufficient, if the coolant level is adequate, and whether the windshield washer fluid needs a refill. The lights and wiper functions will be tested, and finally, a computer scan will be performed to check for any fault codes in the vehicle. It's free, but remember to bring the maintenance manual, as the subsequent warranty will only take effect after the first maintenance is completed. Remember not to add unnecessary paid services; these basic checks are sufficient.

I summarized the first maintenance service into three parts: The must-change items are engine oil and oil filter, as new cars need fresh oil to filter out impurities after the run-in period. There are over twenty must-check items, covering everything from tires and brakes to lights and horns. Fluid inspections include coolant, brake fluid, and power steering fluid – they'll top up if levels are low. The undercarriage inspection checks for loose suspension bolts and exhaust leaks. Last year during my first service, they even upgraded the car's system for free, which is common nowadays. The dealership also cleaned the air filter and washed the car. Remember to bring the maintenance manual and don't exceed the time limit, or it may affect the warranty. Though it's free, keep all receipts properly.

The core of the first vehicle maintenance is to replace the engine oil and filter, removing metal debris from initial engine wear. It is essential to check the levels of three fluids and two oils: coolant, windshield washer fluid, brake fluid, and power steering fluid. Mechanical inspections include tightening chassis suspension components, measuring tire tread depth, and checking the break-in condition of brake discs and pads. The electronic system will be scanned for fault codes using a diagnostic tool, and lights and wipers will be tested and adjusted. Air filters are usually cleaned by blowing out dust rather than replaced. The entire process takes between half an hour to two hours, so remember to book an appointment to save time. The first maintenance is free but affects the vehicle's warranty—do not exceed the mileage or time limit.
