Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
needs to be on or RAP needs to be active. See
ªRetained Accessory Powerº under
Ignition Positions on
page 2-27.
Press and release the rear side of the button located in
the front overhead console to express-open the glass
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.
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 tracks.
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 button 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
tilted rearward. This will reset the memory and enable
the sunroof to function properly.

Care of Your CDs and DVDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen
a clean, soft cloth in a mild, neutral detergent solution
and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD and DVD Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a clean cloth
and gently wipe the video screen. Do not spray
directly onto the screen and do not press too hard or
too long on the video screen.
Fixed Mast Antenna
The ®xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, you can straighten it out by hand.
If the mast is badly bent, as it might be by vandals,
you should replace it.
Check occasionally to be sure the mast is still tightened
to the cowl. If tightening is required, tighten by hand,
then with a wrench one quarter turn.
XMŸ Satellite Radio Antenna
System (United States Only)
Your XMŸ Satellite Radio antenna is located on the
roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
The performance of your XMŸ system may be affected
if your sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of your XMŸ system. Make
sure that the XMŸ satellite antenna is not obstructed.
