Sunroof The vehicle may have a sunroof. It includes a sliding glass panel and a sunshade. The sunroof control is on the headliner, by the map lamps. To raise the sunroof to the vent position, open the sunshade by hand, then press the back of the control. Push and hold the front of the control to close the sunroof from the vent position. With the sunroof in the vent position, press and release the back of the control to express-open the sunroof. The sunshade will automatically open with the sunroof. To stop the express-open function, press the back of the control again. To close the sunroof, press and hold the front of the control. To stop the sunroof, release the control. The sunshade must be closed manually. The sunroof panel cannot be opened or closed if your vehicle has an electrical failure. The sunroof control works only when the ignition is on or in ACCESSORY, or when Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 2-23. 2-47
