Position Of Air Suspension Components
The Cayenne Turbo and the optional Cayenne and Cayenne S are equipped with a level adjustment system with full-supporting air suspension on both axles and the electronically regulated damping of Porsche Active Suspension Management (PASM).
The air suspension with level adjustment makes it possible to actively adapt the ground clearance of the Cayenne to the situation in which the vehicle is being used or to its load. More ground clearance off-road by manual adjustment to off-road level or automatic lowering at high speed.
Depending on the load, by increasing or decreasing the air volume it is possible to achieve various vehicle heights with different suspension characteristics. The amount of air needed for each air spring strut is determined by means of a control unit and provided via an air supply consisting of compressor, a solenoid block and two accumulators.
Wheel acceleration sensors -9- are no longer fitted as of January 2004. If the air-spring struts have to be replaced, the wheel acceleration sensors (for vehicles before January 2004) will need to be installed on the new air-spring struts.
