Basically, the coda should have some whitespace between it and the prior
section of music and should start looking like what you would expect
from the beginning of a new staff line, complete with clefs, key
signatures and time signatures and whatever other miscellaneous
decorations that come with multi-staff layouts. In all, fairly similar
to the image that Robert Murdock posted in "I Too Have Problems with
Codas". Also, it would be nice to have the coda/segno markings laid out
at the appropriate places too (including the top of the coda section),
but first things, first. :-)
