ASSYST PLUS Service Codes Guide

Service B Repairs

Most new Mercedes-Benz vehicles are equipped with ASSYST PLUS, or Active Service System Plus. This system helps Orange County drivers stay up to date with routine repairs and maintenance, allowing them to get the best possible performance from their vehicles. The Mercedes-Benz ASSYST PLUS service codes convey important information quickly to drivers, so they always know where they stand with their car's maintenance guide.

Service Codes

About a month before a service is due, you'll see one of the following messages in your multifunction display:

  • Next Service A in XXX days
  • Next Service A in XXX miles

The letter following "Service" will change, depending on which interval your vehicle needs. For example, after 20,000 miles you'll see a code for Service B. Then, 16,000 miles later, you may receive a reminder for Service C.

If a service interval is missed, ASSYST PLUS will let you know how much time/distance has passed since the due date:

  • Service C exceeded by XXX days
  • Service C exceeded by XXX miles
