Pontiac 2007 G6 - Manual (Page 156)

As the switch is being pressed the windows and
trunk lid will open. The hardtop will automatically
lower into the trunk, and the trunk lid will close and
latch. If the engine is on, a chime will sound when
the hardtop has lowered completely. The Driver
Information Center (DIC) will display TOP MOVE
COMPLT to signal the procedure is complete. See
DIC Warnings and Messages on page 212 for more
information.
After the hardtop has lowered completely, release
the switch. If you continue to press the switch for
about two seconds after the hardtop has completely
lowered, the windows will automatically close.
If pressure is released from the switch before the
hardtop cycle is complete, the cycle will stop and
the Driver Information Center (DIC) will display the
TOP NOT SECURE message. Always press and
hold the switch until a chime sounds, if the engine
is on, and the Driver Information Center (DIC)
displays the TOP MOVE COMPLT to signal the
procedure is complete. See DIC Warnings and
Messages on page 212 for more information.
