Your Mercedes Deserves More Than a Generic Service Bay

The way your vehicle is serviced directly affects how it performs, how long it lasts, and what it’s worth at trade-in. General service centers work from general knowledge. Our technicians are factory-trained on Mercedes-Benz vehicles specifically: the systems, the tolerances, the standards the brand holds itself to.

Every service uses Genuine Mercedes-Benz Parts: components designed and tested for your exact vehicle, not approximations that fit close enough. The right part, installed correctly by someone who knows this vehicle, keeps your warranty intact and your investment protected. For Seacoast drivers who chose this vehicle deliberately, that’s not a small distinction.

Mercedes Service and Maintenance in Greenland, NH

Mercedes-Benz structures its maintenance schedule around two alternating service intervals. Your vehicle’s onboard ASSYST PLUS system monitors your driving conditions, mileage, and time, and displays a notification on your dashboard when a service is due. Here is what each interval covers.

Service A

Service A is typically due at one year or 10,000 miles, whichever comes first. Then it’s due approximately every 20,000 miles or two years after that. It includes:

  • Oil & Filter: Replace with synthetic motor oil and a Genuine Mercedes-Benz oil filter.
  • Fluids: Check and top off all factory-recommended fluid levels.
  • Brakes: Inspect brake components and pad thickness.
  • Tires: Check and adjust tire inflation, and inspect for wear.
  • System Reset: Reset the maintenance counter on your dashboard.
  • Model-specific: Elements unique to your specific model and model year

This is the Mercedes oil change interval. Unlike a general oil service, it uses the exact oil grade and specification your engine requires, performed by technicians following the official Mercedes-Benz service sheet for your model and year.

Service B

Service B is typically due at two years or 20,000 miles, and then approximately every 20,000 miles or two years after that. It covers everything in Service A, plus:

    • Cabin Filter: Replace the cabin dust and combination filter.
    • Brakes: Exchange brake fluid.
  • Tires: In addition to wear and inflation, tire rotation if necessary
  • Model-specific: Additional elements unique to your specific model and model year.

Many owners schedule a Mercedes tire rotation alongside their Service B visit, since the intervals align naturally. However, whether rotation is possible depends on your wheel configuration. Some Mercedes-Benz models come from the factory with a staggered setup, where rear tires are wider than the front, and standard front-to-back rotation isn’t an option.

Our technicians can confirm your configuration and advise on the right approach for your vehicle. 

Diagnostic and Repair Work

When something needs more than scheduled maintenance, our technicians carry Mercedes-Benz-specific diagnostic tools and the factory training to use them accurately. Services include:

  • Engine diagnostics
  • Transmission service
  • Cooling system maintenance
  • A/C and heating repair
  • Full component repair and replacement

All work is performed to factory standards with Genuine Mercedes-Benz Parts.

Service That Works Around Your Schedule

Scheduling service shouldn’t take longer than the service itself. Our online tool is available around the clock. Choose your service, pick a time, and you’re set. Prefer to talk it through? Reach our service team online and we’ll get back to you. 

Our service center is open Monday through Friday, 7:30 AM to 6:00 PM, and Saturday 8:00 AM to 2:00 PM. We offer complimentary loaner vehicles for qualifying visits, so a longer repair doesn’t pull your day off track. We’re at 309 Portsmouth Ave in Greenland; it’s an easy drive from anywhere on the Seacoast.

Proudly Serving Portsmouth, Exeter, Dover, and the Seacoast

Drivers come to us from Portsmouth, Exeter, Dover, Rochester, Hampton, and Southern Maine — and we know the roads they’re driving.

New Hampshire puts real demands on a vehicle. Winter salt, coastal air, and hard seasonal temperature swings wear on tires, brakes, fluids, and finishes in ways a standard service checklist doesn’t always account for. Our technicians factor in those conditions at every visit, keeping your Mercedes ready for the roads it actually runs — not an idealized version of them.

Mercedes Service Questions, Answered

What should I bring when I drop off my Mercedes for service?

Your key fob and any relevant documentation — service history, a recall notice, or warranty paperwork if applicable. If there’s a specific concern, a brief description helps our technicians prioritize accurately.

How long does a Mercedes oil change or tire rotation typically take?

Most routine services are completed within an hour. Times vary depending on your model and whether additional inspection items come up during the visit.

Can I schedule service if my Mercedes is still under warranty?

Yes. Servicing at an authorized Mercedes-Benz dealer keeps your warranty coverage intact. Our technicians follow factory procedures and use Genuine Mercedes-Benz Parts on applicable repairs, as your warranty requires.

What if your technicians find something beyond what I came in for?

We’ll contact you before any additional work is performed. You’ll know what was found, why it matters, and what it will cost. Nothing proceeds without your approval.
