Sunroof (Option)
The sunroof has both manual and express features for
opening the glass panel and sunshade.
The sunroof has four positions, express open, comfort
stop, closed and vent. The switch will only work when
the ignition is on or when RAP is active. See "Retained
Accessory Power (RAP)" in the Index.
If your vehicle has this
option, the switch for
the sunroof is located
on the headliner between
the sun visors.
Press and hold the switch rearward to the first position
to open the glass panel and sunshade. The sunshade can
also be opened manually.
Press and release the switch rearward to the second
position to express open the glass panel to the comfort
stop position. The comfort stop position is designed
to help reduce noise and make passengers more
comfortable. When the glass panel is express opening,
pressing the switch in any direction will stop it in a
-
partially opened position. The glass panel may be fully
opened by pressing the switch rearward again. If you
press and hold the switch in the express open position
for more than one and a half seconds, the express open
operation will be overridden and the sunroof will
operate manually.
To close the glass panel, press and hold the switch
forward. As the glass panel reaches the closed position,
it will open slightly toward the vent position and then
drop down to the closed position to provide a better seal.
The sunshade must be closed manually.
Once the sunroof is closed, it can be opened to the vent
position by pushing the switch upward. To close the
glass panel, pull the switch downward. The sunshade
must be opened and closed manually for vent operation.
