To operate a power sliding sunroof, the ignition must be on, or Retained Accessory Power (RAP) must be active. See Retained Accessory Power (RAP).


Object Number: 2074464  Size: G1

The switch used to operate the sunroof is located in the headliner.

Express Open/Close: To open or close the sunroof, fully press and release the rear or front of the switch. The sunroof automatically opens. To stop the sunroof partway, press the switch a second time. An air deflector raises when the sunroof is fully opened.

Vent: With the sunroof closed, press and hold the front of the switch to vent the sunroof. To stop the sunroof before it reaches its full vent position, release the switch. Press and hold the back of the switch to close.

Do not leave the sunroof open for long periods of time. Excessive debris may collect in the tracks and possibly damage the sunroof operation, or plug the water draining system.

Anti-Pinch Feature

If an object is in the path of the sunroof when it is closing, the anti-pinch feature detects the object and stops the sunroof from closing at the point of the obstruction. The sunroof then returns to the full-open position.

Sunshade Operation

The sunshade automatically opens with the sunroof. Manually pull it shut after the sunroof is closed.

To adjust the sunshade, push it backward or pull it forward to the desired position. The sunshade cannot be adjusted further than the current closed position of the sunroof.
