I'm in a process of removing the car seat cover of Safety 1st Alpha Omega Elite and looking at the manual here, I need to remove the seat base and the harness in order to do so. It's been half an hour and I still couldn't figure out how. It seemed so simple in the manual, but I couldn't find where is the "tab A" on the right of the base to remove the bar. It's such a pain just to remove a cover! geez!

Have anyone own this car seat done this before ? Please help. DD puked and I need to wash the cover and put the car seat back or we are not going anywhere. Thank you!!
