Sunroof (Option) The sunroof has both manual and express features for opening the glass panel and sunshade. If your vehicle has this option, the switch for the sunroof is located on the headliner between the sun visors. Press and hold the switch rearward to the first position to open the glass panel and sunshade. The sunshade can also be opened manually. Press and release the switch rearward to the second position to express open the glass panel to the comfort stop position. The comfort stop position is designed to help reduce noise and make passengers more comfortable. When the glass panel is express opening, pressing the switch in any direction will stop it in a partially-opened position. The glass panel may be fully opened by pressing the switch rearward again. If you press and hold the switch in the express open position for more than one and a half seconds, the express open operation will be overridden and the sunroof will operate manually. To close the glass panel, press and hold the switch forward. As the glass panel reaches the closed position, it will open slightly toward the vent position and then drop down to the closed position to provide a better seal. The sunshade must be closed manually. Once the sunroof is closed, it can be opened to the vent position by pushing the switch upward. To close the glass panel, pull the switch downward. The sunshade must be opened and closed manually for vent operation. The sunroof has four positions, express open, comfort stop, closed and vent. The switch will only work when the ignition is on or when RAP is active. See "Retained Accessory Power (RAP)" in the Index. 2-61
