The goal of maintenance service is to keep your car running at peak efficiency for maximum life expectancy. If you want to get the full value out of your car, it should be serviced at the recommended intervals. Not only will this keep your car running smoothly, but often small problems are detected and fixed before they become big and expensive ones.
Following are the most common maintenance services for Mercedes-Benz.
A/ B Services (every 7,500 miles) for post 1997 models
The most frequent maintenance service for newer models is the “oil, filter, and lube” service. The manufacturer recommends this service every 12,000 miles, but this is based on the German market where driving patterns include non-stop high speeds on the auto-bahn. For driving habits and traditions in the United States, we recommend the A/B Service every 7,500 miles.
The A/B Service is really much more than an oil and filter change. It also includes a comprehensive inspection of other nonrelated subsystems. One of our highly skilled technicians spends at least an hour with your car, going through a detailed checklist which addresses basic safety and mechanical concerns.
The A/ B Service Checklist
- Change oil and filter
- Check condition of engine air filters
- Check condition of cabin filter(s) (where applicable)

We strongly encourage you to keep up-to-date with your maintenance services. We would much rather maintain, than repair, your car. As always, we are available to answer any questions you may have about your particular car.
Some of the newer cars have a flexible service system (FSS). These services will vary according to your driving style. While these service may be extended in mileage, they must be done within the recommended time frame in order to keep your warranty valid.
