Pre-Safe — a development of the Pre-Safe system fitted to the S-Class, which uses sensors to predict collisions, the system also takes account closing speed, as by the vehicle’s radar. If a collision likely, Pre-Safe closes all and the sunroof, moves all passenger’s and their head restraints to a position, and tightens the seatbelts.

Stability Program (ESP) similar to the systems fitted to Mercedes vehicles, this measures driver inputs and these to the vehicle’s path. If diverge, ESP brakes single selectively to eliminate oversteer and understeer (plowing), and reduces power, if necessary.
