Modes of Operation
WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
There are 2 modes of operation available for heated seats; both the seat cushion and seat back heat, or seat back only heat. When a heated seat temperature signal request is received, the heated seat module will activate both the seat cushion and seat back heating elements. When the heated seat BACK ONLY mode button is pressed once the heated seat module will deactivate the seat cushion heating element and leave the seat back heating element ON.
