Sunroof (If Equipped) Your vehicle may be equipped with an express-open sunroof. It includes a sliding glass panel and a one-piece sunshade. The control switch works only when the ignition or retained accessory power is on. See "Retained Accessory Power" in the Index. The control switch is located overhead on the headliner. To open the sunroof to the vent position only, push and hold the front of the switch. You will need to open the sunshade by hand. To close the sunroof from the vent position, push and hold the rear (indented part) of the switch. To open the sunroof, push the rear (indented part) of the switch once. The sunroof and sunshade will open by themselves. This is the express-open feature. To close the sunroof, push and hold the front of the switch until the sunroof motor stops. The sunshade can only be closed by hand. 2-61
