Sunroof If your vehicle has a sunroof, the switch is located between the sun visors. To operate the sunroof using the power switch do the following: 1. When vent opening the sunroof press and hold the side of the switch with the roof symbol on it until the roof is vented. 2. Press and hold the side of the switch with the roof symbol on it again to fully open the roof. The roof will stop when it is fully opened. Releasing the switch at any time will stop the roof at that position. 3. To close the sunroof press the side of the switch opposite of the roof symbol and hold it until the glass panel is seated. The sunroof switch will only work when the ignition is on or when the ignition is off and retained accessory power is active. See "Retained Accessory Power" under Ignition Positions on page 2-17 for more information. 2-42
