Sunroof (If Equipped)
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
or RAP needs to be active. See "Retained Accessory
Power" in the Index.
Press and release the rear side of the button located in
the front overhead console to express
panel and sunshade. To close the glass panel, press and
hold the front of the button. The glass will not be fully
seated unless the button is held until the glass stops
moving. With the sunroof closed, press the forward side
of the button to open the sunroof to the vent position.

The sunroof is also equipped with a sunshade which you
can pull forward to block sun rays. The sunshade will
not close when the sunroof is open.
If a hand, arm, or other object is blocking the sunroof
glass panel as it is closing, the glass panel will stop at
the obstruction. After the obstruction is removed, the
glass panel can be closed or opened.
Use care not to leave the sunroof open for long periods
of time as debris may collect in the tracts.
If the battery has been recharged, disconnected or is not
working, you may need to reprogram the sunroof. To do
this, start the vehicle and press the forward side of the
sunroof switch until the glass panel moves to a fully
closed position. Release, and press again to move to the
vent position which occurs when the sunroof is fully
-
open the glass
tilted rearward. This will reset the memory and enable
the sunroof to function properly.
