Sunroof If your vehicle has a power sliding sunroof, the ignition needs to be turned to RUN, or the Retained Accessory Power (RAP) must be activated to open or close the sunroof. When RAP is active, the sunroof will work for 10 minutes after the ignition is turned off, or until the driver's door is opened. See Retained Accessory Power (RAP) on page 2-24 for more information. Open: From the vent position, the sunroof can be fully opened either manually or by using the express-open feature. To open manually, press the rear of the switch to the first depression and hold until the sunroof has reached the desired position. To open using express-open, press the rear of the switch fully and release. The sunroof will move to the full open position. To stop the sunroof partway, press the switch a second time. Close: From the vent, or open position, press and hold the front of the switch to close the sunroof. Extended Cab If your vehicle is an extended-cab, the sunroof switch is located on the headliner above the rearview mirror. The sunroof also has a roller sunshade that can be used to block the rays of the sun. The roller sunshade can be manually operated with the sunroof in an open or closed position. To open the sunshade, press and unlatch it, and roll it back. To close, pull it forward and latch it into the closed position. When the sunroof is opened, an air deflector will automatically raise. The air deflector will retract when the sunroof is closed. Vent: From the closed position, press and hold the rear of the switch to vent the sunroof. To close the sunroof, press and hold the front of the switch. 2-82
