If your vehicle has this feature, the switch is located on the headliner between the sun visors. The sunroof will only operate while the ignition is in 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, you must first open the sunshade by hand. Then push the switch back and release it.

To fully open the sunroof, push the switch back again and release it.

In both the vent and fully open positions, the air flow can be adjusted for driving comfort by pushing and holding the switch forward until the sunroof moves to the desired position.

To close the sunroof, push the switch 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 your 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.
