Sunroof Your vehicle may have an express-open sunroof. It includes a sliding and tilting glass panel and a sunshade. The switch is located on the overhead console if the vehicle is equipped with a Driver Information Center (DIC). If the vehicle is not equipped with a DIC, the sunroof switch is located on the roof panel headliner. To open the power sunroof, press the switch to the rear twice and the sunroof will open. Open/Express: To activate the express-open feature, press the switch rearward. You can stop the sunroof before it is completely open by pushing the switch forward. Vent: Your sunroof also has a vent feature. It can be activated from the closed sunroof position by pressing the switch once rearward. To close, push and hold the sunroof switch forward. When using this feature, the sunshade should be fully opened in the rear position. The sunshade can be opened manually by sliding it rearward, or automatically, by opening the power sunroof. You will need to close the sunshade manually by sliding it forward. Close: To close the sunroof, push the switch forward and hold until the sunroof motor stops, or release the switch when the desired position has been reached. DIC Version Shown The switch works only when the ignition is in ACC, ON or when Retained Accessory Power (RAP) is active. 2-44
