If your vehicle has this feature, the sunroof control is located on the headliner between the sun visors. The sunroof will only operate while the ignition is on.

The sunroof can be opened to a vent position or it can be express-opened all of the way.

To open the sunroof to the vent position, push the sunshade rearward. Then press the sunroof control rearward and release it.

To fully open the sunroof, push the control rearward again and release it.

In both the vent and fully open positions, the sunroof position can be adjusted by pressing and holding the sunroof control forward until the sunroof moves to the desired position.

To close the sunroof, press he control forward and hold it until the sunroof is closed. The sunroof will stop if the switch is released during operation. Close the sunshade by hand.

The sunroof glass panel cannot be opened or closed if the vehicle has an electrical failure.

Notice: Forcing the sunshade forward of the sliding glass panel may cause damage and the sunroof may not operate properly. Always close the glass panel before closing the sunshade.
