I would say definitely give it a good overnight charge. Cycle the windows together all the way down, all the way up and all the way down again. Then try the top.
I usually have my engine running and trans in park when I put the top down or up. The other day, I thought I would be cute. I was stuck in traffic on the Garden Grove Express way. It was nice and warm and I was bored. I know my top will operate with the car stopped even while in gear. Well, I started to put the top down. Just as it settled in the well, traffic started to crawl a little. I let my foot off the brake and..........light started flashing, something started beeping and the top cover stopped all the way up!

Nothing I did would start or stop it. Oh crap, here I am rolling along in four lanes of traffic at 5 mph, with the latch up and nowhere to pull over. I finally did get off to the shoulder after about a mile. Stopped the car, trans to park, key off, then on. The top finished cycling fine. PHEW!
Where is the little icon for "Dumb****"?
