Mercedes-Benz Service B is a maintenance schedule recommended to keep your vehicle in top condition. It is part of the Mercedes Flexible Service System and alternates with Service A every 10,000 miles. Service B is recommended every 20,000 miles or 12 months after you have completed the Service A interval. The exact time for Service B varies with the vehicles specifics and is not time-dependent. The following are some of the services included in Mercedes-Benz Service B:

• Replacing the oil filter and Mercedes-Benz motor oil
• Inspecting and correcting tire pressure
• Checking fluid levels and modifying them as needed
• Checking brake components
• Checking the battery and charging system
• Inspecting the suspension and steering components
• Checking the operation of the lighting system

The cost of Service B varies based on the model you own and the parts needed. Routine maintenance, including Service B, is not covered under new car or extended warranty plans for Mercedes. However, the cost is relatively low for the services provided, and skipping routine service intervals can lead to performance issues such as engine misfires.
