Sunroof If the vehicle has a sunroof, the switch to operate it is located on the headliner, between the sun visors. Notice: Opening the sunroof when the luggage rack crossrails are not in the full-rear position could cause damage to the sunroof or luggage rack. Verify the luggage rack crossrails are in the full-rear position before opening the sunroof. Press the rear of the switch to open the sunroof to the vent position. The sunshade must be opened by hand. Press and release the rear of the switch a second time to express-open the sunroof. The sunshade will open with the sunroof. Press the switch in either direction to stop it from moving. If the rear of the switch is pressed and held, the express-open operation will be overridden. To close the sunroof, press and hold the front of the switch. The sunroof switch will only work when the ignition is ON or when the ignition is OFF and Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 129. 169
