Playing a CD
If the ignition or radio is turned off, with a CD in the
player, it will stay in the player. When the ignition
or radio is turned on, the CD will start playing where it
stopped, if it was the last selected audio source.
When a CD is inserted, the CD symbol will appear on
the display. As each new track starts to play, the
track number will appear on the display.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.If playing a CD-R the sound quality may be reduced
due to CD-R quality, the method of recording, the quality
of the music that has been recorded, and the way the
CD-R has been handled. There may be an increase
in skipping, difficulty in nding tracks, and/or difficulty in
loading and ejecting. If these problems occur try a
known good CD.
Do not add paper labels to CDs, they could get caught
in the CD player.
If an error appears on the display, see “CD Messages”
later in this section.

Before You Drive
The RSE system is for rear seat passengers only. The
driver cannot safely view the video screen while
driving and should not try to do so.
Headphones
The RSE system includes two sets of wireless
headphones.
Each set of headphones has an ON/OFF control. An
indicator light will illuminate on the headphones
when they are on. If the light does not illuminate, the
batteries may need to be replaced. See “Battery
Replacement” following for more information.
Each set of headphones has a volume knob. To adjust
the volume, adjust this knob.
The transmitters are located below the video display
screen. The headphones will shut off automatically
if they lose the signal from the system after about four
minutes to save battery power. The signal may be lost if
the system is turned off or if the headphones are out
of range of the transmitters.When using the wired headphones, if the front seat
passengers play a CD in the Radio with Six-Disc CD (if
equipped) or use XM™ Satellite Radio Service (if
equipped), you will hear the audio for these sources,
instead of the DVD or CD that is currently playing
through the RSE.
Notice:Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs would not be covered by your warranty.
Keep the headphones stored in a cool, dry place.
Battery Replacement
To change the batteries, do the following:
1. Loosen the screw on the battery compartment door
located on the left side of the headphone earpiece.
2. Replace the two AAA batteries in the compartment.
Make sure that they are installed correctly, using the
diagram on the inside of the battery compartment.
3. Tighten the screw to close the compartment door.
If the headphones are to be stored for a long period
of time, remove the batteries and keep them in a cool,
dry place.

DVD Player
The DVD player is located in the overhead console. The
DVD player can be controlled by the buttons on the DVD
player and/or by the buttons on the remote control. See
“Remote Control” later in this section for more
information.
The DVD player power may be turned on when the
ignition is in RUN, ACCESSORY, or when Retained
Accessory Power (RAP) is active.
The RSE system DVD player is only compatible with
DVDs of the appropriate region code for the country that
the vehicle was sold in. The DVD region code is
printed on the jacket of most DVDs.Standard audio CDs, CD-R, CD-RW, Video CD and
Photo CD/CD-R media are fully supported by this DVD
player. DVD-R and DVD-RW media is supported if
formatted as DVD-Video. DVD+R and DVD+RW media
may or may not be supported by the DVD player.
The DVD player does not support DVD-RAM,
DVD-ROM, and DVD Audio media. An error message
will appear on the display if this type of media is inserted
into the DVD player.
When using the wired headphones, not included, if the
front seat passengers play a CD in the Radio with
Six-Disc CD (if equipped) or use XM™ Satellite Radio
Service (if equipped), you will hear the audio for these
sources, instead of the DVD or CD that is currently
playing through the RSE.
If an error message appears on the video screen, see
“DVD Messages” later in this section.

DVD Distortion
There may be an experience with audio distortion in the
wireless headphones when operating cellular phones,
scanners, CB radios, Global Positioning Systems
(GPS)*, two-way radios, mobile fax, or walkie talkies.
It may be necessary to turn off the DVD player
when operating one of these devices in or near
the vehicle.
* Excludes the OnStar
®System.
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.
Navigation/Radio System
Your vehicle may have a navigation radio system that
includes Radio Data System (RDS) with Program Type
(PTY) selections that will seek out the kind of music you
want to listen to and XM™ Satellite Radio Service
capabilities (if equipped). The radio can also
communicate with the navigation system to broadcast
announcements on traffic, weather, and emergency alert
communications. For information on how to use this
system, see the “Navigation System” manual.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the sources: radio, cassette tapes, CDs, or DVDs.
However, the rear seat passengers can only control the
sources that the front seat passengers are not listening
to. For example, rear seat passengers may listen to and
control cassette tapes, CDs, or DVDs through the
headphones while the driver listens to the radio through
the front speakers. The rear seat passengers have
control of the volume for each set of headphones.
The front seat audio controls always have priority over
the RSA controls. If the front seat passengers switch the
source for the main radio to a remote source, the RSA will
not be able to control the source. You can operate the
rear seat audio when the main radio is off.

Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. Static
can occur on AM stations caused by things like
storms and power lines. Try reducing the treble to
reduce this noise.
FM Stereo
FM stereo will give the best sound, but FM signals will
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO SIGNAL to indicate interference.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat. If they are not, they may not operate
properly or may cause failure of the tape player.
The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLEAN to
indicate that the tape player has been used for 50 hours
without resetting the tape clean timer. If this message
appears on the display, the cassette tape player
needs to be cleaned. It will still play tapes, but it should
be cleaned as soon as possible to prevent damage
to the tapes and player. If there is a reduction in sound
quality, try a known good cassette to see if the tape
or the tape player is at fault. If this other cassette has no
improvement in sound quality, clean the tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer.
3-137

The broken tape detection feature of the cassette tape
player may identify the cleaning cassette as a
damaged tape, in error. To prevent the cleaning cassette
from being ejected, use the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE CD button for ve seconds.
READY will appear on the display and a cassette
symbol will ash for ve seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
After the cleaning cassette is ejected, the broken
tape detection feature will be active again.
A non-scrubbing action, wet-type cleaner which uses a
cassette with a fabric belt to clean the tape head
can be used. This type of cleaning cassette will not
eject on its own. A non-scrubbing action cleaner may not
clean as thoroughly as the scrubbing type cleaner.
The use of a non-scrubbing action, dry-type cleaning
cassette is not recommended.After the player is cleaned, press and hold the EJT
button for ve seconds to reset the CLEAN indicator.
The radio will display CLEANED to show the indicator
was reset.
Cassettes are subject to wear and the sound quality may
degrade over time. Always make sure the cassette tape
is in good condition before the tape player is serviced.
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.
