E39 cars are Wed with side-impact airbags in the front
doors. Some are equipped with
airbags in the rear doors
as well. When servicing the door windows on cars with
side-impact airbags, always disconnect the negative

reason it can be removed and installed with the window in
any position and does not need reinitialization.
