Sunroof
On vehicles with a sunroof, the switches used to operate it are on the headliner above the rearview mirror. The ignition must be in ON/ RUN or ACC/ACCESSORY, or in Retained Accessory Power (RAP) to operate the sunroof. See Ignition Positions on page 9‑21 and Retained Accessory Power (RAP) on page 9‑25.
