What does 3a3b maintenance mean?

3a3b maintenance refers to three major maintenance services and three minor maintenance services. A maintenance and B maintenance represent minor and major maintenance respectively. A maintenance is relatively simple, basically involving basic inspections, while B maintenance includes more items and more thorough inspections. Relevant details are as follows: 1. The main items of car maintenance include: changing engine oil, oil filter, transmission oil, spark plugs, cabin air filter, air filter, brake fluid, etc. 2. Maintenance involves inspection and servicing of multiple vehicle systems including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, tires, and dozens of other items.
When I first started driving, I was curious about what '3a3b maintenance' meant. Now I understand it's a term for Hyundai's maintenance cycle. The '3' represents the procedure number, like 30,000 kilometers. 'A' is basic maintenance: oil and oil filter change, plus tire and fluid checks; 'B' is more comprehensive, including everything in 'A' plus air filter or cabin air filter replacement. My car reached 30,000 kilometers and underwent 3B maintenance. The technician said the engine breathes better after changing the filters. Not doing it on time carries big risks—engine wear accelerates and fuel consumption increases. I got it done at the dealership for a few hundred bucks. The manual has a list, and I usually keep an eye on the dashboard reminders to ensure my car runs safely on long trips. New drivers shouldn't skimp on these small expenses—regular maintenance extends the car's lifespan.
