Question..... why are people trying to give him advice on how to clear an upcoming service reminder on his 453 by providing steps on how to do it on a 451? They're not even remotely the same car, with not even remotely the same setup. There are no buttons on the instrument panel on a 453.
@bostonjoe This is the first i'm hearing of a service reminder for how many DAYS remaining.... must be something with the newer ones? *shrug*. But on my 2016 453, To reset the service interval, all i need to do is be on that display in the instrument panel, and then just press and hold the OK button for a long.... LONG time. It'll eventually start flashing, and then it should reset. It may be different for post-2016 models... even moreso for ED's rather than ICE's.
edit: Come to think of it.... I think for the ICE models, there is a rather EARLY recommended service just to do an oil change. For some reason I think it's for like 1,000-2,000 miles? Pretty sure it was the same when i got my 2009 Brabus brand new, too. I guess because of it being a new motor, best to get whatever bits might be lingering around out of the oil rather than letting it go for 10k miles. Maybe it's something leftover from that? Who knows.
