Section 2 Features and Controls
2-2

Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
A (LOCK):This position locks your ignition and
transmission. It's a theft-deterrent feature. You will only
be able to remove your key when the ignition is
turned to LOCK.
B (ACCESSORY):This position lets you use things like
the radio, power windows and the windshield wipers
when the engine is off.
Notice:If your key seems stuck in LOCK and you
can't turn it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.
C (RUN):This is the position for driving.
D (START):This position starts your engine.
Retained Accessory Power (RAP)
Your vehicle may be equipped with a Retained
Accessory Power (RAP) feature which will allow certain
features on your vehicle to continue to work up to
10 minutes after the ignition key is turned to OFF.
Your radio, power windows, sunroof (if equipped), and
OnStar
žSystem (if equipped) will work when the ignition
key is in RUN or ACCESSORY. Once the key is
turned from RUN to LOCK, these features will continue
to work for up to 10 minutes or until a door is opened.
2-22

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition or
RAP needs to be active. See²Retained Accessory
Power²under Starting and Operating Your Vehicle.
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. 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 tilted rearward. This will reset the memory and
enable the sunroof to function properly.

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 (48 Contiguous US States)
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.
Chime Level Adjustment
The radio is the vehicle chime producer. To change the
volume level, press and hold pushbutton 6 with the
ignition on and the radio power off. The chime volume
level will change from the normal level to loud, and LOUD
will be displayed on the radio. To change back to the
default or normal setting, press and hold pushbutton 6
again. The chime level will change from the loud level to
normal, and NORMAL will be displayed. Each time the
chime volume is changed, three chimes will sound as an
example of the new volume selected. Removing the radio
and not replacing it with a factory radio or chime module
will disable vehicle chimes.
