General information
NOTE: This section covers the air suspension control system. The front suspension is covered in a separate section. For more information refer to Front Suspension (204-01 Front Suspension). The rear suspension is covered in a separate section. For more information refer to Rear Suspension (204-02 Rear Suspension). The Terrain Response™ system is covered in a separate section. For more information refer to Ride and Handling Optimization (204-06 Ride and Handling Optimization)
The dynamic suspension system includes four air springs and is fitted to high end vehicles in place of the conventional spring suspension found on models without air suspension.
The dynamic suspension system is controlled by the air suspension control unit, which regulates the operation of the compressor unit, responds to signals from four sensors and distributes compressed air throughout the system through valve blocks.
The main components and parts of the air suspension system:
- Air suspension control unit
- Compressor block
- Four height sensors
- Three valve blocks assy
- Receiver
- Air line
- Four modules of pneumatic suspension shock absorbers
The four-shock absorber air suspension system maintains a predetermined vehicle height in all operating conditions by controlling the mass of air in the elastic pneumatic elements. The air suspension control unit maintains the desired suspension height based on signals from four height sensors. To do this, it controls the pneumatic control valves, increasing and decreasing the mass of air in the elastic pneumatic elements of the shock absorber modules.
The air suspension system has three preset heights that can be selected by the driver. The driver interface provides a display of the selected height and direction of travel. The driver also receives additional information via the instrument cluster message center display (in the presence of) and by means of sound signals from the instrument panel.
Altitude change is only possible with the engine running and the driver and passenger doors closed. The low height can be selected with the engine off for 40 seconds after the ignition is turned off, provided that the driver's door is not opened during this time.
The driver can manually control the air suspension using a switch on the center console, selecting the desired height.
