Sunroof (Option)
Your sunroof includes a sliding glass panel and a sliding
sunshade. The switch is located between the sun visors
just ahead of the sunroof and works only when the
ignition is on.
To open the glass panel and sunshade, press the rear of
the switch. Let go of the switch to stop the panel in any
position. Press the front of the switch to close the glass
panel. The sunshade can only be closed by hand.
The sunroof glass panel cannot be opened or closed if
your vehicle has an electrical failure.
