What does service B mean on Mercedes e220?

Service B is a scheduled maintenance service for Mercedes-Benz vehicles with the Mercedes-Benz 4-MATIC AWD system. The service includes an oil change, brake fluid flush, and inspection of the driveshaft, differential, and brakes. The service interval for Service B is every 10,000 miles or 1 year, whichever comes first.

Here is a more detailed breakdown of what each of the service tasks involves:

2. Brake Fluid Flush: This involves draining the old brake fluid from the system and replacing it with new fluid. New brake fluid helps to keep the brakes working properly and prevents them from becoming spongy or failing.
