Navigation/Radio System
Your vehicle may be equipped with a navigation radio
system includes digital sound processing (DSP),
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
(48 contiguous US states, if equipped). The radio system
can also communicate with your 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 Entertainment System

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.

Audio Output
Audio from the DVD player or auxiliary inputs may be
heard through the following possible sources:
Wireless Headphones
Vehicle Speakers
Vehicle wired headphone jacks on the Rear Seat
Audio system (if equipped)
The RSE system will always transmit the audio signal
by infrared to the wireless headphones, if there is audio
available. See “Headphones” previously for more
information.
The RSE system is capable of outputting audio to the
vehicle speakers by using the radio. The RSE
system may be selected as an audio source on the
radio if the RSE system power is on. Once the
RSE system is selected as an audio source on the radio
adjust the speaker volume on the radio, if necessary.
If the RSE system power is not on, the RSE system will
not be an available source on the radio. Refer to the
radio information for the radio that your vehicle has for
more information.The RSE system is capable of outputting audio to the
wired headphone jacks on the rear seat audio system
(if equipped). The RSE system may be selected as
an audio source on the rear seat audio system if

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.
3-117

The front seat audio controls always have priority over

Radio Personalization
If your vehicle has this feature, it allows the driver to
return to the last used source: radio, cassette, or
CD using the remote keyless entry transmitter. This
feature can also store and recall AM and FM presets,
volume, tone, and the last selected radio station.
The number on the back of each transmitter, 1 or 2,
corresponds to driver 1 or 2. If transmitter 1 is used to
enter the vehicle, the last used audio source and/or
settings set by driver 1 will be recalled. If transmitter 2
is used to enter the vehicle, the last used audio
source and/or settings set by driver 2 will be recalled.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identication Number
(VIN). If the radio is moved to a different vehicle, it
will not operate and LOCKED will appear on the display.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.
With THEFTLOCK
®activated, the radio will not operate
if stolen.
Audio Steering Wheel Controls
Some audio controls can be adjusted at the steering
wheel. They include the following:
g(OnStar/Voice Recognition):If your vehicle has
OnStar®, press this button to interact with the OnStar®

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.
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.
