Carenado Cessna c337 Skymaster altitude hold

I just bought he Carenado Skymaster, but I"m having some problems with the autopilot. I cant find where to read, or set my designated altitude, or virtical speed and I cant find anything about autopilot in the manual.
Can someone please tell me where to find the altitude readout and how to set new altitude and virtical speed?
