If the vehicle has a panoramic sunroof, it has four glass panels that tilt or stack upon each other, when the sunroof control is turned to the vent or one of three opened positions. There is a separate control for the automatic sunshade.

The sunroof will only operate while the ignition is ON/RUN, in ACC/ACCESSORY, or if Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) .

The panoramic sunroof control is located on the headliner. From the closed position, turn the control clockwise to vent the sunroof or open it to three different positions.

0 (Closed Position): Turn the control to this position to close the panoramic sunroof.

1 (Vent Position): Turn the control to this position to vent the panoramic sunroof . The front glass panel of the sunroof will tilt forward and the sunshade will automatically retract to the vent position.

2 (First-Open Position): Turn the control to this position to open the panoramic sunroof about a third of the way. The second glass panel will retract and the fourth glass panel will stack above the roof. The sunshade will automatically retract to this position.

3 (Second-Open Position) : Turn the control to this position to open the panoramic sunroof about half-way. The second glass panel will retract and the third panel will stack in front of the fourth glass panel. The sunshade will automatically retract to this position.

4 (Full-Open Position): Turn the control to this position to completely open the panoramic sunroof. The second glass panel retracts and stacks in front of the third and fourth panels. The sunshade will automatically retract to the full-open position. To lessen wind noise in this position, use the automatic sunshade control and close the sunshade to the comfort stop position. See "Sunshade" following.

Anti-Pinch Feature

If an object is in the path of the sunroof when it is closing, the anti-pinch feature will detect the object and stop the sunroof from closing at the point of obstruction. The sunroof will then reverse direction.

Sunshade


Object Number: 1501119  Size: A2

The automatic sunshade control is located on the headliner, between the map lamp controls.

The sunshade can be independently opened or closed while the panoramic sunroof is closed. To express-open or express-close the sunshade, press and release the control rearward or forward. The sunshade will retract to the full-open or closed position. To stop the movement of the sunshade, press the control a second time. To close the sunshade to a particular position, continue to press the control and release it when the desired position is reached.

Neither the panoramic sunroof nor the sunshade can be opened or closed if the vehicle has an electrical failure.
