Here's what Lexus says:

* The height control is self-levelling according to the passenger/luggage weight of the vehicle
* The sport/comfort/normal switch select "3 types of damping forces for the shock absorber assemblies."
* The suspension using "repercussion control (nonlinear H∞ control)" "as a result of a focus on body control in the roll direction."
* Whereas normal suspension (on other cars) suppresses only heave (bouncing) on each wheel independently, active suspension uses all 4 wheels in consort to suppress heave, roll and pitch (sideways movement).
* "Compared to the conventional roll posture control based on the steering sensor signal, a yawrate sensor (deceleration sensor signal) is actively utilized to more finely detect vehicle conditions when turning, thus optimizing and smoothening the damping force switching. "
