• First Service (Service A): Typically around 10,000 miles or 1 year, whichever comes first. This ensures essential fluids, filters, and basic component checks are performed.
• Second Service (Service B): Usually around 20,000 miles or 2 years, whichever comes first (or 1 year/10,000 miles after Service A). This expands on Service A with more in-depth checks and component replacements like cabin and engine air filters.

Subsequent Services and Interval-Based Maintenance

After the initial services, the schedule typically alternates between Service A and Service B, with additional items added at longer intervals. These longer-term maintenance tasks are critical for the longevity of specific components.

Interval	Common Services	Key Components Checked/Replaced
Every 10,000 miles / 1 year	Service A	Engine oil, oil filter, tires, brakes, fluid levels, hoses, seals, wipers.
Every 20,000 miles / 2 years	Service B	All Service A items, plus cabin air filter, engine air filter, deeper brake inspection, suspension, steering.
Every 30,000 miles / 3 years	Service A (or B, depending on cycle)	Similar to the previous interval, potentially including a more thorough inspection of the cooling system.
Every 40,000 miles / 4 years	Service B (or A, depending on cycle)	Includes all items from the last Service B, often adding checks for ignition components like spark plugs (especially if not replaced earlier) and a more detailed look at exhaust systems.
Every 60,000 miles / 6 years	Service B (typically)	Includes all items from the last Service B. Might also include a brake fluid change if not done sooner.
Every 70,000 – 100,000 miles (or as indicated)	Major Service / Specific Component Replacement	Spark plugs (often around 70k-100k miles), transmission fluid and filter, differential fluid, coolant flush, potentially serpentine belt replacement. These are highly model-dependent and crucial for long-term reliability.

Longer-Term Maintenance for Mercedes SUVs

Beyond the recurring Service A and B, specific components have extended service life requirements that are vital for maintaining your SUV’s integrity:

• Brake Fluid: Typically replaced every 2 years, regardless of mileage. This is critical because brake fluid is hygroscopic, meaning it absorbs moisture from the air, which can lower its boiling point and compromise braking performance, especially in demanding situations.
• Transmission Fluid and Filter: While some modern “sealed” transmissions may not have a scheduled fluid change, many Mercedes-Benz models still benefit from it, often around 70,000-100,000 miles. This is a significant service that can extend the life of your transmission. Consult your specific model’s manual or a dealer for guidance.
• Coolant: Mercedes-Benz vehicles use specific coolant types. A coolant flush and replacement are typically recommended between 5 and 10 years, or around 100,000 miles, to ensure the system is protected against corrosion and maintains optimal operating temperature. For more on cooling system maintenance, educational resources from organizations like the National Highway Traffic Safety Administration (NHTSA) often highlight the importance of cooling systems for vehicle safety and emissions control.
• Spark Plugs: These are often recommended for replacement around 70,000 to 100,000 miles. Worn spark plugs can lead to inefficient combustion, reduced power, and increased fuel consumption.
• Drive Belt (Serpentine Belt): Usually inspected at every service, replacement is often recommended between 60,000 and 100,000 miles, depending on the material and condition, to prevent an engine-crippling failure.
