Regular maintenance at a 4S store includes engine oil, oil filter, fuel filter, spark plugs, transmission fluid, coolant, tire rotation, timing belt, wheel alignment, and dynamic balancing. Below is relevant knowledge about car maintenance: 1. Primary maintenance: Mainly involves cleaning, lubrication, and tightening, along with inspecting safety components related to braking and operation. 2. Secondary maintenance: Primarily involves inspection and adjustment, including tire disassembly and inspection, and tire rotation. Before secondary maintenance, diagnostic testing and technical evaluation should be conducted to determine additional tasks or minor repairs based on the results, which are then carried out alongside the secondary maintenance. The frequency of each level of maintenance depends on the vehicle type and operating conditions.

Every time I take my car to the 4S shop for maintenance, it's like giving it a comprehensive check-up. The technicians start by changing the engine oil and oil filter, which helps the engine run smoother, reduces noise and wear, and I've noticed the engine sounds quieter on long drives. Then they inspect the braking system, measuring the thickness of the brake pads—if they're too thin, they need replacing to avoid accidents from failed emergency braking. The tires aren't overlooked either; they check the air pressure and tread wear, performing balancing adjustments when necessary, making highway driving much more stable. The lighting system is fully illuminated for inspection—how dangerous would it be if a bulb went out while driving at night? Coolant and brake fluid are also tested to prevent overheating in summer or brake failure. The chassis inspection is a key focus, checking for loose screws or oil leaks. Software updates are now common too, fixing minor glitches. Overall maintenance is done every 5,000 kilometers or six months. Though it costs a bit, it saves on major repairs later, extends the car's lifespan by several years, and significantly improves the driving experience.

I think 4S shops are very professional when it comes to maintenance, as they follow a standardized process. They start with the basics like changing the engine oil and oil filter to keep the engine running smoothly. Then they check the brake pads—if they're too worn out, they need to be replaced; otherwise, braking failure could lead to accidents. The tires are inspected for pressure and wear rate, and rotated if necessary to ensure even wear and extend their lifespan. All lights, including turn signals and fog lights, are tested. The cooling system is checked for antifreeze levels to prevent issues during hot seasons. Brake fluid and power steering fluid are also inspected to ensure responsive performance. They even scan the computer system and update the software to enhance stability. Regular maintenance every 5,000 kilometers is a must—safety on the road comes first. A friend of mine skipped maintenance to save money, and his brakes failed, costing him a fortune in repairs and nearly causing an accident. So, timely visits to the 4S shop are worth it—small expenses prevent major risks.

4S shop maintenance services are quite comprehensive, basically including oil and filter changes. Once the oil is replaced, the engine gets lubricated and runs smoothly. Brake inspection is a key focus, checking if the pads and discs are excessively worn to avoid failure at critical moments. Tire pressure and tread depth are measured to ensure strong grip in rainy conditions. All lights must be functioning to prevent blind spots at night. Coolant level checks prevent overheating and engine seizure. Brake fluid inspection prevents soft brakes and accidents. Technicians also examine chassis components like suspension and shock absorbers for looseness or leaks. Software updates are common to upgrade the computer system. These services, performed every six months, effectively prevent malfunctions. Maintenance isn’t just about preserving the car’s condition—it’s crucial for safety, which I always prioritize.

The maintenance items at the 4S store are not numerous but very practical. First is changing the engine oil and oil filter, making the engine run smoother and saving fuel. Brake inspection checks the pad thickness, replacing them when too thin to prevent accidents. Tire inspection checks pressure and wear to enhance handling. Lighting system verification ensures all bulbs are functioning to improve nighttime visibility. Coolant and brake fluid checks ensure no leaks or solidification. Chassis scanning identifies loose screws or oil leaks to prevent damage to other components. Software updates fix system bugs, making the car's smart systems more user-friendly. These are done every six months at a low cost but save worry and money. I've calculated that spending a few hundred each time prevents major repairs costing thousands. A car needs maintenance as it ages, just like regular exercise keeps it strong and durable.
