Few things are as fun or as thrilling as carving the streets of Corona and Fontana in your Mercedes-Benz CLS. Whether you drive a standard CLS Coupe or a potent Mercedes-AMG® model, top-level performance is a given. It’s also a given that you want to preserve that performance for years to come, and the best way to do that is by following the Mercedes-Benz CLS maintenance schedule.
When you follow Service A and Service B requirements, maintaining your CLS is simple! Mercedes-Benz of Ontario provides everything CLS drivers need to know in the guide below.
Your Mercedes-Benz CLS maintenance journey begins with Service A*, which is required after 1 year or 10,000 miles, whichever comes first. From there, the next major CLS service requirement is Service B*, occurring after 2 years or 20,000 miles, whichever comes first. You’ll rotate between Service A and Service B for the duration of your CLS ownership in Rancho Cucamonga. What’s more, you’ll have the ASSYST PLUS system to alert you of upcoming service requirements—there’s no need to track it yourself.
