488 spider battery issue.

Hi; Here is the description of a problem I am having with my 2018 488 spider. The battery was drained so I trickled charged it and had a full charge after a couple of days, however, upon starting I am getting warrning lights for AVH, EBP and Manettino. Manettino is stuck on WET and I can not change it. I drove it a few miles after charging hoping that the warnings would be reset to no avail. Is there a way to reset these warning lights short of going to a dealer? There are a couple of suggestions on some forums about going through a sequence of turning the car on and off and leaving it off for 30 minutes. I tried it and it doesn't work. Any help is appreciated.
