Sunroof (Option) Press and release the ROOF switch rearward to the second position to express-open the glass panel to the comfort stop position, approximately half-way open. The comfort stop position is designed to help reduce noise and make the rear seat passengers more comfortable. The glass panel may then be fully opened by pressing the ROOF switch again. If you press and hold the ROOF switch in the express-open position for more than one second, the express-open operation will be over-ridden and the sunroof will stop when the switch is released. To stop the glass panel when express opening, press the the ROOF or VENT switch forward or rearward and release. The two switches that operate the sunroof are located on the overhead console and include VENT, ROOF, open and close. Press and hold the ROOF switch rearward to the first position to open the glass panel and sunshade. The sunshade also can be opened or closed manually. To close the glass panel, press and hold the ROOF switch forward. As the sunroof 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. To vent the glass panel, press and hold the VENT switch in the open position. The sunshade must be opened manually when using the vent position. To close the glass panel, press and hold the VENT switch in the close position. The ROOF and VENT switches work only when the ignition is on or when RAP is active.
