SLK/R170: Do The R170's even have a dyno mode?

I've searched as best I can to find the way to put a 2002 SLK 320 into dyno mode, but I can't seem to find it. The only method I've found is posted in the C class boards quite a few times, but I couldn't find anything regarding SLKs.
Could anyone tell me the way to put an R170 into dyno mode please?
thanks, it's greatly appreciated.
