Mercedes-Benz Maintenance
The Definitive Guide: Service A vs. Service B
An essential visual guide for owners to understand the critical differences in their vehicle's maintenance schedule and protect their investment.
The Alternating Service Schedule
Your Mercedes-Benz (MY 2009+) operates on a smart, alternating schedule to ensure all systems are checked at the right time. The cycle begins with Service A and alternates with the more comprehensive Service B annually.
A
1 Year / 10,000 Miles
First Service
B
2 Years / 20,000 Miles
Second Service
A
3 Years / 30,000 Miles
Third Service
B
4 Years / 40,000 Miles
Fourth Service
Service A
The Foundational Check-Up
Service A is the essential annual service that addresses the most fundamental aspects of your vehicle's health, focusing on the engine's lifeblood and key safety inspections.

- ✔Tire Inflation Check & Correction
- ✔Brake Component Inspection

Service B
The Comprehensive Wellness Exam
Service B includes every task from Service A, plus two critical component replacements that address long-term wear and are vital for safety and cabin health.
- ✔All Service A Tasks
- +Cabin Dust/Combination Filter Replacement
- +Brake Fluid Exchange
Why Service B's Additions Are Non-Negotiable
Brake Fluid Exchange
Brake fluid is hygroscopic, meaning it absorbs water over time. This moisture contamination dangerously lowers the fluid's boiling point and corrodes internal components.
A fluid exchange prevents brake fade and protects the expensive ABS module.
Cabin Air Filter
A clogged cabin filter restricts airflow, strains the HVAC system, and allows pollutants and allergens to enter the cabin.
Replacement protects passenger health and prevents premature HVAC blower motor failure.

- Engine Air Filter Replacement
BlueTEC® Diesel
- AdBlue® (DEF) Fluid Replenishment
- Critical Fuel Filter Replacement
- Specific Oil Specification Check
