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.
Stereo RCA Jacks
The RCA jacks are located behind the video screen.
The RCA jacks allow audio and video signals to
be connected from an auxiliary device such as a
camcorder or a video game unit to the RSE system.
Standard RCA cables, not included, are needed
to connect the auxiliary device to the RCA jacks. The
yellow connector inputs video and the red and white
connectors input right and left audio. Refer to the
manufacturer’s instructions for proper connection of the
auxiliary device.

Video Screen
The video screen is located in the overhead console.
To use the video screen, push forward on the release
latch and the screen will fold down. Adjust the screen’s
position as desired. When the video screen is not in
use, push it up into its latched position.
The DVD player and display will continue to operate
when the screen is in the up or the down position.
The video screen contains the transmitters for the
wireless headphones and the remote control. If the
screen is in the closed position, the signals will not be
available for the operation of the headphones or
the remote control.
Notice:Directly touching the video screen may
damage it. Do not touch the screen. See “Cleaning
the Video Screen” later in this section for more
information.
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.

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.
3-125

When cleaning the cassette tape player with the
recommended non-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut
tape detection feature on the radio may recognize it as a
broken 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 DISC button for
ve seconds. READY will appear on the display and
the 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.
When the cleaning cassette has been ejected, the
cut 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 eject
button for ve seconds to reset the CLEAN indicator.
The radio will display --- or 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.
Care of Your CD and DVD Player
The use of CD lens cleaners for CDs is not advised, due
to the risk of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.

And, of course, actual stopping distances vary greatly
with the surface of the road (whether it is pavement
or gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of
the vehicle and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking.
If you keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking and
longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-41.
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.

The traction off light will come on under the following
conditions:
The Traction Assist System is turned off, either by
pressing the TAS on/off button, located on the
instrument panel, or by turning off the automatic
engagement feature of the TAS.
The transmission is in FIRST (1); TAS will not
operate in this gear. This is normal.
The vehicle is driven on an extremely rough road.
When the vehicle leaves the rough surface, slows
down or stops, the light will go off and TAS will turn
on again. This is normal.
A Traction Assist System, Anti-Lock Brake System
or engine-related problem has been detected and
the vehicle needs service.
If the vehicle has been driven with the TAS system
on for long periods of time, or if the vehicle has
gone through many several high speed braking
maneuvers the system may be automatically
disabled. The system will automatically re-enable
after approximately two minutes of not using
the brakes.SeeTraction Off Light on page 3-41.
The Traction Assist System, as delivered from the
factory, will automatically come on whenever you start
your vehicle. To limit wheel spin, especially in
slippery road conditions, you should always leave the
system on. But you can turn the TAS off if you ever need
to. You should turn the TAS off if your vehicle ever
gets stuck in sand, mud or snow and rocking the vehicle
is required. SeeRocking Your Vehicle to Get It Out
on page 4-48andIf You Are Stuck: In Sand, Mud, Ice
or Snow on page 4-48.
To turn the system on or
off press the TAS on/off
button located on the
instrument panel.
If you used the button to turn the system off, the traction
off light will come on and stay on. You can turn the
system back on at any time by pressing the button
again. The traction off light should go off.
