I cannot, for the life of me, find the toggle switch for the door seal system that's described on page 161 of the manual. I must be blind. Can someone please post an image showing where it is? Thank you for your time.
Just a hunch here, but are you flying the reciprocating engine version of the aircraft? This switch is only present in the turbine version of the aircraft. The manual is split into two parts for the two versions of the aircraft, beginning with the full-page note ~page 153.
