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
ªRemote Controlº 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 XMŸ 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
ªDVD Messagesº later in this section.

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 ªBattery
Replacementº 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 XMŸ 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.
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.
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.
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 you to connect audio and
video from an auxiliary device such as a camcorder or a
video game unit to your RSE system. Standard RCA
cables 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 stereo
audio. Refer to the manufacturer's instructions for
proper connection of your auxiliary device.

DVD Distortion
You may experience audio distortion in the
IR 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
žSystem.
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.
XMŸ Satellite Radio Service
(48 Contiguous US States)
XMŸ 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.
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.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLEAN to
indicate that you have used your tape player for
50 hours without resetting the tape clean timer. If this
message appears on the display, your cassette
tape player needs to be cleaned. It will still play tapes,
but you should clean it as soon as possible to
prevent damage to your tapes and player. If you notice
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.
3-129

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.
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 your 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 is active again.
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 cleanermay 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 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 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.

Anti-lock Brake System
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. See
Anti-Lock
Brake System Warning
Light on page 3-45
.
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's 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.

·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.
See
Traction Off Light on page 3-45.
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. See
Rocking Your VehicleunderIf You
Are Stuck: In Sand, Mud, Ice or Snow on page 4-51.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.
If desired, you can change the TAS automatic
engagement feature so that the system will not come on
automatically when the engine is started. To do so:
1. Park the vehicle with the ignition off and the
transmission in PARK (P).
2. Turn the ignition to RUN; do not start the engine.
3. Apply the brake pedal, shift into NEUTRAL (N),
press the accelerator pedal to the ¯oor, then
press the TAS on/off button and hold it down for at
least six seconds.
4. Release the TAS button and both pedals.
5. Turn off the ignition and wait a few seconds.

When you are back on roads, though, be sure to
replace the air dam.
Notice:Operating your vehicle for extended
periods without the front bumper lower air dam
installed can cause improper air ¯ow to the engine
and may allow things like fog lamps or tow hooks
on the front of your vehicle to be damaged. Always
be sure to replace the front bumper air dam when
you are ®nished off-road driving.
To reinstall the lower air dam, do the following:
1. Line up each push-pin
with its intended
retainer and push the
washer portion of
the push-pin toward
the retainer until it locks
into place.2. Push the ¯at end of the
push-pin toward the
retainer until it
locks into place,
making sure each is
secure.
Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields (if so equipped) are properly
attached. Be sure you read all the information about
your four-wheel-drive vehicle in this manual. Is
there enough fuel? Is the spare tire fully in¯ated? Are
the ¯uid levels up where they should be? What are the
local laws that apply to off-roading where you will be
driving? If you do not know, you should check with law
enforcement people in the area. Will you be on
someone's private land? If so, be sure to get the
necessary permission.
