From those internal documents its also noted that:

Operation on brake test rigs
Selector lever position N must be engaged on vehicles with xDrive and automatic gearbox for testing on brake test rigs. In this setting, the transfer case clutch remains open and the vehicle cannot be pulled out of the test rig.

In the case of vehicles with xDrive and manual gearbox, the accelerator must not be pressed when the vehicle is on the test rig to ensure the transfer case clutch is not closed.
"Closed" means engaged, driving the front, "open" means dis-engaged, rwd operation only.
