Sunroof
The vehicle may have a sunroof. It includes a sliding
glass panel and a sunshade.
The sunroof control is
on the headliner, by the
map lamps.
The sunroof control works only when the ignition is on
or in accessory, or when Retained Accessory Power
(RAP) is active. See Retained Accessory Power (RAP)
on page 2-22.
To raise the sunroof to the vent position, press the back
of the control. Push and hold the front of the control
to close the sunroof from the vent position.
With the sunroof in the vent position, press and release
the back of the control to express-open the sunroof.
The sunshade will automatically open with the sunroof.
To stop the express-open function, press the back
of the control again.
To close the sunroof, press and hold the front of the
control. To stop the sunroof, release the control.
The sunshade must be closed manually.
The sunroof panel cannot be opened or closed if your
vehicle has an electrical failure.
