A Mercedes-Benz is one of the most sophisticated vehicles ever built. To keep it performing at its best, regular maintenance isn't optional — it's essential. Here are the key maintenance points every Mercedes owner should know.
Oil Changes: Don't Skip Them
Mercedes-Benz vehicles use synthetic oil and have longer service intervals than most cars, but that doesn't mean you can ignore them. Follow your ASSYST PLUS system's recommendations and always use the correct specification oil — MB 229.5 or MB 229.51 for most modern models.
Brake Fluid: The Overlooked Essential
Brake fluid is hygroscopic — it absorbs moisture over time, which lowers its boiling point and can compromise braking performance. Mercedes recommends replacing brake fluid every two years regardless of mileage. This is especially important for AMG models that see spirited driving.
Tire Pressure and Rotation
Many Mercedes models use run-flat tires, which can mask pressure loss. Check your tire pressure monthly and rotate your tires every 7,500 miles. Proper tire maintenance extends tire life and maintains the handling precision that makes your Mercedes special.
Software Updates
Modern Mercedes-Benz vehicles are essentially computers on wheels. Mercedes regularly releases over-the-air software updates that improve performance, add features, and fix issues. Make sure your vehicle is connected and receiving these updates.
- Oil change: per ASSYST PLUS, typically every 10,000 miles
- Brake fluid: every 2 years
- Cabin air filter: every 15,000 miles or annually
- Spark plugs: every 60,000 miles
- Transmission fluid: every 40,000 miles for AMG models
"A well-maintained Mercedes is a joy forever. Neglect it, and you'll feel it in ways that go beyond the repair bill."
— Edwardo Calderon, Mercedes-Benz of Coral Gables
