Power Sunroof Operation
WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
The Power Sunroof System will operate only with the ignition turned to the RUN or Accessory positions, this allows for retained accessory power (RAP) control of the sunroof through the body control module (BCM). With the ignition in the run or accessory positions, the BCM supplies the sunroof with ignition voltage which allows sunroof operation. Once the ignition switch is turned to OFF the sunroof will continue to operate until any door is opened or when the RAP timer reaches its shut-off limit. For a description and operation of the RAP operation, refer to Retained Accessory Power Description and Operation .
The rear sunroof is a fixed glass and does not open. The front and rear sunshades will have to be manually opened or closed.
