put a jump starter on the battery and then put car in neutral.
otherwise the manual states:
ehicles with automatic transmission: If the automatic transmission cannot be shifted to position i,have the vehicle transported away(→ page306).

The ISM used to be backed up by a very small battery, or by the stop/start battery. Seems this backup power source does not exist any more on the W213.

The backup is to shift the car into park only, to keep it from rolling away, not the other way around. There is no emergency neutral shift mechanism.
The 725 transmission actually has 3 ways to put itself into park as safety backups, but it can only release the way it normally does with battery power (it actually runs the transmission's auxiliary oil pump and hydraulically lifts the park pawl locking pin). The backup battery power can be used to force it into park if the whole system dies electronically, but it's a one-way solenoid that pulls a pin that retains a spring so it snaps into park.
