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). Rear suspension is covered in a separate section. For more information, see Rear Suspension (204-02 Rear Suspension). The Terrain Response™ system is discussed in a separate section. For more information, see Ride and Handling Optimization (204-06 Ride and Handling Optimization)
The dynamic suspension system includes four air shock absorbers and is installed on high-end vehicles instead of the conventional coil spring suspension used 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.
Main components and parts of the air suspension system:
- Air suspension control unit
- Compressor unit
- Four height sensors
- Three valve blocks assembled
- Receiver
- Air highway
- Four modules of air shock absorbers of suspension
The four-shock absorber air suspension system maintains the vehicle's set height under all operating conditions by controlling the air mass in the elastic pneumatic elements. The air suspension control unit maintains the required suspension height based on signals from four height sensors. To do this, it controls the air control valves, increasing and decreasing the air mass 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. (if available) and by means of sound signals from the instrument panel.
The height can only be changed when the engine is running and the driver and passenger doors are closed. A lower height can be selected when the engine is 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.
