If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Listening to a DVD
If your vehicle has Rear Seat Entertainment (RSE)
system and a DVD is playing, the DVD symbol
will appear on the radio display indicating that the DVD
is available and can be listened to through your
vehicles speakers. To listen to the DVD, press the CD
AUX button until RSE appears on the radio display. The
current radio source will stop and the DVD sound will

the DVD, press the CD AUX button, if a CD is loaded,
or press the BAND button to select a different source.
When the RSE system is turned off, the DVD symbol will
go off of the radio display and RSE OFF will appear

Rear Seat Entertainment System
Your vehicle may have the optional Digital Versatile Disc
(DVD) Rear Seat Entertainment (RSE) system. The
RSE system includes a DVD player, a video display
screen, two sets of wireless headphones, and a remote
control.
Before You Drive
The RSE system is for rear seat passengers. The driver
cannot safely view the video screen while driving and
should not try to do so.
DVD Player
The DVD player is located in the overhead console.
The DVD player can be controlled by the buttons on the
DVD player 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 DVD 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 and CD-RW discs) can also
be played in this DVD player.
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
(48 contiguous US states, 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.

Battery Replacement
To change the batteries, do the following:
1. Remove the battery compartment door located on
the bottom of the remote control.
2. Replace the two AA batteries in the compartment.
Make sure that they are installed correctly, using
the diagram on the inside of the battery
compartment.
3. Close the battery door securely.
Notice:Do not store the remote control in heat or
direct sunlight. This could damage the remote
control and it would not be covered by your vehicles
warranty. Keep the remote control stored in a
cool, dry place.
If the remote control is to be stored for a long period of
time, remove the batteries and keep them in a cool,
dry place.
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 headphones will automatically turn off if they lose
the infrared signal from the system after approximately
four minutes in order to preserve their battery power.
The signal may be lost if the system is turned off or if the
headphones are out of range of the infrared signal
transmitters that are located below the video display
screen.
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
(48 contiguous US states, if equipped), you will hear the
audio for these sources, instead of the DVD or CD
that is currently playing through the RSE.

(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.
Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines.
Try reducing the treble to reduce this noise.
FM Stereo
FM stereo will give you 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 come and go.
XM™ Satellite Radio Service
(48 Contiguous US States)
XM™ Satellite Radio gives you 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 come and go. Your radio may display
NO SIGNAL to indicate interference.
3-117

You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to
clean the tape head. 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 you clean the player, 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 you have your tape
player 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.
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.

Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights will come on
accompanied by a 10-second chime. The lights and
chime will come on each time the ignition is turned on
until the problem is repaired. See your dealer for service.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
