Cadillac CTS - Manual (Page 154)

Anti-Pinch Feature
If an object is in the path of the sunroof when it is
closing, the anti-pinch feature will detect the
object and stop the sunroof from closing at the
point of the obstruction. The sunroof will then
return to the full-open or vent position. To close
the sunroof once it has re-opened, turn the control
to the closed position.
Anti-Pinch Feature Override
A condition may exist that causes the anti-pinch
feature of the sunroof to activate due to weather or
an obstruction. In an emergency, the anti-pinch
feature can be overridden in a supervised mode.
To override the anti-pinch feature rotate the
sunroof control to the closed position, then press
the control upward and continue pressing
upward until the sunroof reaches the desired
position.
In this mode, the sunroof can still close on an
object in its path. Use care when using the
override mode.
