4S maintenance items are divided into routine maintenance and immediate maintenance items. Routine maintenance includes the following: 1. Engine oil and oil filter are generally replaced every 5,000 kilometers, brake fluid and power steering fluid are usually replaced every 40,000 kilometers or 2 years, manual transmission fluid is generally replaced every 80,000 kilometers, and automatic transmission fluid is typically replaced every 60,000 kilometers. 2. The fuel filter is generally replaced every 15,000-20,000 kilometers. 3. Spark plugs are usually replaced every 50,000 kilometers, coolant every 40,000 kilometers, tire rotation every 10,000 kilometers, and timing belt every 60,000-70,000 kilometers, not exceeding 80,000 kilometers. 4. Fuel system cleaning is performed every 20,000 kilometers, and lubrication system cleaning every 10,000 kilometers. 5. Air conditioning disinfection is done every six months or 20,000 kilometers. 6. Wheel alignment and dynamic balancing are performed every 20,000 kilometers. Immediate maintenance includes: air filter replacement, cabin air filter replacement, and brake pad replacement.

Every time I drive to the 4S dealership for maintenance, I find the process quite comprehensive. Starting with an oil change, it's required every 5,000 kilometers or so—draining the old oil and adding new oil to protect the engine. The oil filter is also replaced simultaneously to trap impurities and maintain internal cleanliness. Checking and replacing the cabin air filter is essential to prevent dust buildup and keep the air inside fresh. For the tires, they check the pressure, inspect tread depth, and often rotate them to extend their lifespan. The braking system gets a thorough inspection, including measuring pad thickness and topping up fluid levels to prevent sudden failure. Battery condition testing is a must every time, especially in cold weather when it's prone to losing charge and affecting startup. Suspension components are checked for looseness or unusual noises to ensure smooth driving. Various fluids, like coolant and brake fluid, are topped up if low. All lights, from headlights to turn signals, are tested for proper function. Finally, a diagnostic scanner checks the electronic system to clear any potential error codes. These tasks take time but keep the car running smoothly, giving peace of mind and reducing breakdowns—overall, it's a worthwhile investment.

I really enjoy delving into the details of cars, and the maintenance items designed by 4S stores are quite scientific. The core is oil change, removing old oil and adding new lubricant to extend engine life. The oil filter is replaced in conjunction to filter out contaminants. The air filter maintains the purity of the intake system to avoid debris clogging. The cabin air filter replacement improves in-car air quality and reduces odors. The tire segment includes pressure adjustment and rotation balancing to promote even wear and enhance safety. The brake system checks pad thickness and fluid quality to ensure responsive performance. Battery testing evaluates charge capacity and health. Suspension components are meticulously inspected for bolt tightness and shock absorber condition. Various fluids such as coolant and brake fluid are checked for levels to prevent leakage failures. Lights are fully verified for proper functionality. The vehicle's electronic control unit is diagnosed to catch hidden issues. These maintenance steps systematically enhance vehicle performance, reduce the likelihood of sudden failures, and optimize daily driving experience.

During my first car maintenance at the 4S shop, everything felt quite novel. They performed multiple inspections: replacing engine oil and filters to lubricate the engine internals and extend its lifespan. The cabin air filter was renewed to ensure fresh and comfortable airflow. Tire pressure was checked and corrected for underinflation issues, with rotation performed to balance wear. Brake pads were inspected for excessive thinness, and fluid levels were topped up to prevent hazards. Battery testing was conducted to avoid embarrassing roadside breakdowns. Suspension components were checked for looseness and reinforced to prevent driving instability. Coolant and brake fluid were replenished to maintain smooth system operation. All lights, including headlights and taillights, were confirmed functional to enhance visibility. Electronic diagnostics scanned for error codes to address minor issues early. The entire process was straightforward and required no specialized knowledge, making me feel thoroughly cared for and ensuring worry-free driving.
