Mercedes-Benz Service A Checklist

Service A* is typically due at 1 year or 10,000 miles, whichever comes first. Tasks can vary by model and year, but Service A generally includes:

  • Synthetic motor oil replacement**
  • Oil filter replacement**
  • All fluid level checks and corrections per factory intervals
  • Tire inflation check and correction
  • Brake component inspection
  • Reset maintenance counter (ASSYST or ASSYST PLUS)
  • All required elements listed by model year and specific model on the official service sheet

Mercedes-Benz Service B Checklist

Service B* is typically due at 2 years or 20,000 miles, whichever comes first. It builds on Service A with added maintenance:

  • Synthetic motor oil replacement**
  • Oil filter replacement**
  • All fluid level checks and corrections per factory intervals
  • Tire inflation check and correction
  • Brake component inspection
  • Reset maintenance counter (ASSYST PLUS)
  • Cabin dust/combination filter replacement
  • Brake fluid exchange
  • All required elements listed by model year and specific model on the official service sheet

Note: Select CLA and GLA AMG® models may receive an engine air filter replacement during Service B based on the applicable service sheet.

Service A vs. Service B: What’s the Difference?

Both services follow Mercedes-Benz factory guidelines and cover core inspections, oil service, fluid checks, tire pressure, and brake components. The key differences are the timing (Service A ≈ 10,000 miles/1 year; Service B ≈ 20,000 miles/2 years) and the added items in Service B—typically the cabin filter and a brake fluid exchange. Your vehicle’s on-board ASSYST PLUS maintenance system may recommend additional items depending on time, mileage, and driving conditions.

Why These Services Matter

  • Performance: Factory-spec oil and filters help maintain efficiency and smooth power delivery.
  • Safety: Brake inspections and fluid exchanges support confident stopping performance.
  • Air Quality: Cabin filter replacement keeps interior air fresh and helps HVAC performance.
  • Longevity: Following the recommended intervals helps protect major components over time.
