I was referring to all scheduled maintenance (including oil, air filters, and checking fluids, etc. per the manufacturer's published maintenance schedule).
The way this usually works is you have to get the maintenance service performed by a franchised dealer, per the manufacturer's schedule. The dealer then stamps the little book that comes with the car as proof of service. If something needs fixed under warranty, the first thing they do is look at the little book and if it isn't stamped up-to-date the warranty is voided and you have to pay. The warranty usually contains fine print to the effect: "all scheduled maintenance must be performed by a franchised dealer...".
I don't know how strict about this smart will be, but a lot of manufacturer's are real particular about it.
