Can't do it with the remote. Supposedly a safety thing so you can't accidentally close it on someones head.
Welcome to the forum, and thanks for adding the tip. As a complement to opening the windows with the fob, closing the windows and moonroof can be done by turning the physical key (found/released from the base of key fob) to the left. Closing can't be done via fob presumably for safety reasons (i.e. Honda wants you to visually see/confirm nothing is in the path of closing the window or moonroof).If you double click unlock and then hold the unlock button, the windows and sunroof open. Nice on a hot day for sure.
