Modes of Operation

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

There are 3 modes available for climate control seat system operation, heated seat, cool seat, and back only heat operation. When a heat or cool seat mode signal request is received, the CCSM will activate both the seat cushion and seat back ventilation modules. When the seat BACK ONLY mode button is pressed once, the CCSM will deactivate the seat cushion ventilation module and leave the seat back ventilation module ON. Press the BACK ONLY mode button a second time and the CCSM will re-activate the seat cushion ventilation module.
