It's the aux battery... It probably needs a charge, driving the car for a bit and then maybe restarting should ale care of it...
Either the car was parked for a while and the batter just needed a light charge to get going or you probably need to get it checked out by a Benz repair specialist...
For me driving it around for about 15 min and the. Restarting helped out just fine...
