A maintenance items include: engine oil, oil filter, lubrication maintenance, windshield washer fluid top-up, full vehicle fluid inspection, computer diagnostics, drainage system check, tire tightening, tire pressure check (5 tires), chassis inspection (suspension, brake discs, pads, and all chassis components), interior inspection (horn, headlight washer, seat belts, interior lights, cigarette lighter, and all functions), battery test, maintenance light and tire pressure light reset. B maintenance items include: air filter replacement, cabin air filter replacement, air conditioning system sterilization, sunroof lubrication, intake tract, throttle body, and fuel injector cleaning without disassembly, in addition to all A maintenance items. Definition of car maintenance: Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Purpose of car maintenance: The purpose of car maintenance is to keep the vehicle clean and tidy, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life.

Mercedes-Benz's Service A and B packages are quite practical. I've been driving a Mercedes C-Class for over two years and have gone through several cycles. Service A is performed every 10,000 kilometers, which basically includes an oil change, oil filter replacement, plus tire inspection and inflation, checking lights and fluid levels to ensure small components are functioning properly. Service B builds upon Service A, typically alternating every 20,000 kilometers, adding tasks like replacing the air filter and cabin air filter, along with a thorough inspection of brake pads and systems. This design helps prevent major issues—for instance, delaying an oil change when the oil is dirty could damage the engine, or a clogged filter might affect air conditioning performance. During my last Service B, the technician adjusted the brake balance for me, saying it could prevent skidding during sudden braking. Sticking to the maintenance schedule is hassle-free, keeping the car smooth and reliable. I recommend not skipping these services—it significantly lowers long-term maintenance costs.

The system for Mercedes-Benz vehicles is highly systematic, with alternating A and B services covering key maintenance needs. Service A is more basic, involving oil changes, oil filter replacements, tire pressure adjustments, and light inspections, required every 10,000 kilometers. Service B is more comprehensive, adding air filter replacements, cabin air filter replacements, and brake performance tests such as pad thickness measurements every 20,000 kilometers on top of Service A. These services prevent engine carbon buildup, air conditioning odors, or brake failure risks, ensuring driving efficiency. Neglecting them can lead to increased fuel consumption, and a clogged air filter may even reduce engine power. The maintenance cycle is calculated based on mileage, but adjusting it according to driving habits can improve accuracy. Regular maintenance extends the vehicle's lifespan. A friend of mine delayed a service once, resulting in dust leaking into the engine due to a faulty air filter, costing over 5,000 RMB in repairs—far more expensive than routine maintenance.

Safety is the top priority when driving, and the A/B maintenance program serves as the core defense line. The A maintenance, performed every 10,000 kilometers, includes basic checks such as engine oil and lights to prevent minor issues from accumulating. The B maintenance, conducted every 20,000 kilometers, covers more extensive items like air filter replacement and brake inspections to avoid accidents caused by contaminated air filters or worn brake pads. I’ve developed a habit of adhering to the schedule, and each time, technicians scan the system to uncover hidden faults—early detection means early resolution. For instance, low brake fluid left unchecked can dangerously increase stopping distance. By alternating A and B maintenance, my car remains in stable condition, giving me peace of mind even on highways. Complete maintenance records also enhance vehicle reliability, so never risk delaying service to save time.

From an economic perspective, A/B maintenance is a cost-effective investment. The A-service costs around a thousand yuan, covering oil changes and basic inspections, while the B-service is slightly more expensive, including air filter and cabin filter replacements. Alternating every 10,000 or 20,000 kilometers, though it requires some expenditure, prevents major repair costs. I've compared—a single B-service costs just over two thousand yuan, whereas neglecting it could lead to clogged air filters, increasing fuel consumption and repair costs by tens of thousands. Regular maintenance keeps the car in good condition and boosts resale value. I set aside a small monthly amount as a maintenance fund, easily covering the costs. Remember, minor maintenance saves big money—Mercedes-Benz vehicles are high-quality but rely on care, making it a worthwhile long-term investment.

Mercedes-Benz's A/B services are now quite convenient, with smart systems simplifying the process. A-service includes routine oil changes and light inspections, while B-service upgrades with air filter replacements, etc. The app automatically sends reminders and allows for scheduling. With just a few taps on my phone, I can head to an authorized service center, where technicians perform targeted checks like tire pressure adjustments or brake inspections based on records—all done in just over an hour. This alternating design helps prevent sudden failures, such as poor cabin air quality from delayed air filter replacements, which can impact health. Integrated app reports show trends, allowing maintenance frequency to be adjusted based on driving conditions for a more personalized approach. Daily driving becomes worry-free, as technology makes upkeep effortless and highly efficient without any hassle.
