if they disconnected the battery at any time then there are items that need to be relearned. We can only relearn so many without a scan tool so we can try , we need to make sure all windows and sunroof can work with the auto open and close function first of all. if they do not let me know, then also we need to move the front seats to the max position in all directions, forward, up , back , and down, then the same to the steering wheel, forward, up, back , down, to relearn all the positions, this should clear the presafe, if it does not you need to get it to the benz dealer so the scan tool can learn the seats and steering wheel automatically, presafe is a safety function in the event of a crash the car will move the seats, and steering wheel and windows and sunroof to a better position in the event of a crash so if they are not learned electronically then the warning will be on the dash, hope this helps, Lou P.
