“Bounce Mode” from Mercedes-Benz explained! 

The innovative E-Active Body Control suspension system from Mercedes-Benz allows the SUV to literally “bounce” itself out of a sticky situation.
A build on from the Magic Body Control first introduced in 2013 on the S-Class, the new E-Active Body Control system allows for one of the most advanced suspension features of any car.
Road Surface Scan uses a camera to read the road ahead of the car to prepare the suspension system for any imperfections and irons them out when the car reaches them.
Curve Mode allows the car to lean into bends like a motorcycle, offering up to three different levels of curve for the vehicle.
Free Driving Mode can allow the car to rock up and down to help get the vehicle out of sand or mud should the vehicle be stuck.
Individual Wheel Control allows the driver to control every wheel in the car individually and in real time. Thus off roading on with E-Active Body Control is unmatched in the automotive industry.
