The intelligent distribution of air is the secret behind AIRMATIC DC.For instead of conventional coil springs AIRMATIC DC uses air springs which are made harder or softer by the electronics to suit the driving situation. If the sensors e.g.register a sporty style of driving,the comfortable basic spring setting is automatically stiffened.The springs and shock absorbers can also be manually adjusted by moving a switch to the Comfort or Sport position The fully automatic electronics work with four different damping stages(adaptive damping system)which suit the damping forces acting on each individual wheel to the current requirements and road conditions.As a result the vehicle progresses smoothly even on poor roads,without compromising handling stability.And to keep the vehicle at a constant level the system is also equipped with an all—round level control function.Even with the car fully loaded this ensures an almost constant ground clearance—and therefore greater stability.The suspension can be automatically lowered when traveling at high speed,reducing pitch and yaw. If required,e.g.on extremely poor road surfaces,the suspension can also be raised manually by up t0 55 mm.
