Information Feature Display

Due to the number of pneumatic lumbar/bolster features available, and that the 4-way multi-function switch controls different operations depending on feature selection, the information display is used for the visual feedback of the feature selected as well as which operations of the feature are under the control of the 4-way multi-function switch.

The seat memory control module will track and maintain which lumbar/bolster features are available on the vehicle as well as the current feature selection and its settings. This information is communicated via GMLAN to the radio tuner which in turn communicates it to the information interface for display. The display will show a seat image with the specific selected feature highlighted. In addition, arrows and text will indicate the functions to be adjusted by the 4-way multi-function switch.

If the seat selection menu is not showing on the display, adjusting the lumbar/bolster seat switches will bring this menu up. Only when the display is active and the various features are displayed by the infotainment system, then customer can then use the rotary ring to move up or down the feature menu. The display will show a seat image with the specific selected feature highlighted along with arrows and text to indicate the functions to be adjusted by the 4-way multi-function switch.
