Try a little harder, Qfortyfiver. I searched post bodies in recent threads for the terms y33 suspension and found this on the second page:
Y33 ADJUSTABLE SUSPENSION DESCRIPTION
Also new for 1999 is an Active Damper Suspension, available as standard equipment on the Q45t. This system offers electronically modulated shock valuing control with SPORT and AUTO driver selectable settings.
The system uses real-time, independent 4-wheel shock absorber damping force regulation in response to input from vertical G-sensors and steering angle sensors. Signals from these sensors are sent to the system's computer control unit, then matched with vehicle speed. "Instruction" data is then sent back to actuators above each individual shock absorber, which immediately adjust shock absorber damping force.
The system helps eliminate excessive body movement, such as in hard cornering, braking or acceleration. It also helps improve tire-to-road surface contact for greater stability and enhanced handling control.
With the two adjustable settings, drivers can chose between a softer, more comfortable ride or a firmer ride with more road feel, depending on road surface, traffic and climate conditions or personal preferences.
