2026 MercedesBenz GLE

At Mercedes-Benz of Kalamazoo, we want to help you understand your vehicle’s needs to preserve its performance, safety, and luxury. As a proud owner, seeing a maintenance reminder light might spark questions: is it time for Service A or Service B, and what exactly is the difference? Both services are critical parts of the Mercedes-Benz Flexible Service System, designed to alternate at regular intervals to ensure your car continues to run like new.

When Do You Need Service?

Generally, the schedule works like this:

  • Service A: The first visit is at approximately 10,000 miles or 1 year, whichever comes first. After that, it typically occurs every 20,000 miles or 2 years.
  • Service B: The first visit is at approximately 20,000 miles or 1 year after your previous service. It then alternates with Service A every 20,000 miles or 2 years.

Here is a breakdown of what our factory-trained technicians perform during each visit.

What’s Included in Service A

Service A is the first major service interval for your vehicle. It covers the essentials to ensure your engine is clean and your key safety components are functioning correctly.

According to the Mercedes-Benz maintenance schedule, Service A includes:

  • Mercedes-Benz Motor Oil Replacement: We use only synthetic motor oil approved for your specific engine.
  • Oil Filter Replacement: A genuine Mercedes-Benz fleece oil filter is used to trap impurities.
  • Fluid Level Checks and Corrections: We inspect all vital fluids (coolant, power steering, windshield washer, etc.) and top them off as needed.
  • Tire Inflation Check and Correction: Proper tire pressure is vital for fuel efficiency and handling; we ensure yours are set to spec.
  • Brake Component Inspection: A visual check of brake pads and rotors to ensure you have safe stopping power.
  • Reset Maintenance Counter: We reset your vehicle’s service indicator so you know exactly when your next visit is due.

What’s Included in Service B

Service B is a more comprehensive checkup. It includes all the foundational work of Service A but adds critical filter changes and fluid exchanges to address wear and tear that happens over longer periods.

According to the Mercedes-Benz maintenance schedule, Service B includes:

  • Mercedes-Benz Motor Oil Replacement: Just like in Service A, fresh oil is essential for engine health.
  • Oil Filter Replacement: Ensuring clean oil circulates through your engine.
  • Fluid Level Checks and Corrections: A re-check of all vital vehicle fluids.
  • Tire Inflation Check and Correction: Adjusting pressure for safety and tire longevity.
  • Cabin Dust/Combination Filter Replacement: This is a key difference. We replace the filter that cleans the air coming into your cabin, removing dust, pollen, and pollutants to keep your interior air fresh.
  • Brake Component Inspection: A thorough check of the braking system.
  • Brake Fluid Exchange: Over time, brake fluid absorbs moisture which can lower its boiling point and cause corrosion. We flush the old fluid and replace it with new fluid to maintain optimal braking performance.
  • Reset Maintenance Counter: Resetting the system for your next Service A interval.
