Initialization/Teach Procedure

WARNING: This page is about a different car, the 2023 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • If the switch is held for more than 10 s after the glass has completed the Initialization/Teach Procedure, the sunroof may enter a "stuck switch" fault condition. If this happens, repeat the Initialization/Teach Procedure, making sure to release the switch when the sunroof glass panel has stopped moving.

Ignition ON and the glass panel is in full closed position, press and hold the close switch for greater than 15 s. The glass panel will open to vent, go to fully open, and then the fully closed position. Once the sunroof glass panel has closed, release the switch.
