Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features intended to
minimize driver distraction. Technology alone, no matter
how advanced, can never replace your own judgment.
See the Navigation System manual for some tips to help
you reduce distractions while driving.
Rear Seat Entertainment (RSE)
System
Your vehicle may have the 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.
3-87

Before You Drive
The RSE system is for rear seat passengers only and is
not intended for the driver while driving.
Parental Control
This button is located behind the video screen. Press
this button while a DVD or CD is playing to freeze the
video and mute the audio. The video screen displays
Parental Control ON and the power indicator light on
the DVD player ashes. It also disables all other button
operations from the remote control and the DVD player,
with the exception of the eject button. Press this button
again to restore operation of the DVD player.
This button can also be used to turn the DVD player
power on and automatically resume play if the ignition
is in RUN, ACCESSORY, or if Retained Accessory
Power (RAP) is active.
Headphones
The RSE system includes two sets of wireless
headphones.
Each set of headphones has an ON/OFF control.
An indicator light illuminates 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 shut off automatically if
they lose the signal from the system after about
four minutes to save battery power. The signal can
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 will not be covered by your warranty.
Storage in extreme cold can weaken the batteries.
Keep the headphones stored in a cool, dry place.
Both sets of rear seat headphones may include foam
ear pads.
The foam ear pads can become worn or damaged if
they are not handled or stored properly. They can
be replaced separately from the headphone set.
The headphone replacement foam ear pads can be
ordered in pairs. See your dealer/retailer for more
information.

Battery Replacement
To change the batteries on the headphones:
1. Loosen the screw to the battery door on the left
side of the headphones and slide open.
2. Replace the two batteries in the compartment.
Install correctly using the diagram on the inside
of the battery compartment.
3. Replace the battery door and tighten the door
screw.
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.To use the auxiliary inputs on the RSE system, connect
an external auxiliary device to the color-coded RCA jacks
and turn both the auxiliary device and the RSE system
power on. If the RSE system had been previously in the
DVD player mode, pressing the SRCE button on the
faceplate or the remote control switches the RSE system
between the auxiliary device and the DVD player.

to be working, the batteries may need to be replaced.
See “Battery Replacement” later in this section.
Objects blocking the line of sight can also affect the
function of the remote control.
Notice:Storing the remote control in a hot area or
in direct sunlight can damage it, and the repairs will
not be covered by your warranty. Storage in extreme
cold can weaken the batteries. Keep the remote
control stored in a cool, dry place.

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite radio
signals, causing the sound to fade in and out. In
addition, traveling or standing under heavy foliage,
bridges, garages, or tunnels may cause loss of the XM™
signal for a period of time. The radio may display NO
SIGNAL to indicate interference.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, straighten it out by hand. If the mast is badly
bent, replace it.
Check occasionally to make sure the mast is still
tightened to its base. If tightening is required, tighten
by hand, then with a wrench one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of the
XM™ system may be affected if the sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
the XM™ Satellite Radio antenna is not obstructed.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime level.
To change the volume level of the chime, press and hold
pushbutton 6 with the ignition on and the radio power off.
The volume level will change from the normal level to
loud, and LOUD CHIME will appear on the radio display.
To change back to the default or normal setting, press
and hold pushbutton 6 again. The volume level will
change from the loud level to normal, and NORMAL
CHIME will appear on the radio display. Removing the
radio and not replacing it with a factory radio or chime
module will disable vehicle chimes.

Surface Obstacles:Unseen or hidden obstacles can
be hazardous. A rock, log, hole, rut, or bump can startle
you if you are not prepared for them. Often these
obstacles are hidden by grass, bushes, snow, or even
the rise and fall of the terrain itself. Here are some things
to consider:
Is the path ahead clear?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill? There is
more discussion of these subjects later.
Will you have to stop suddenly or change direction
quickly?
When you drive over obstacles or rough terrain, keep a
rm grip on the steering wheel. Ruts, troughs, or other
surface features can jerk the wheel out of your hands if
you are not prepared.
When you drive over bumps, rocks, or other obstacles,
the wheels can leave the ground. If this happens,
even with one or two wheels, you cannot control the
vehicle as well or at all.Because you will be on an unpaved surface, it is
especially important to avoid sudden acceleration,
sudden turns, or sudden braking.
In a way, off-road driving requires a different kind of
alertness from driving on paved roads and highways.
There are no road signs, posted speed limits, or signal
lights. You have to use your own good judgment
about what is safe and what is not.
Drinking and driving can be very dangerous on any
road. And this is certainly true for off-road driving.
At the very time you need special alertness and driving
skills, your reexes, perceptions, and judgment can be
affected by even a small amount of alcohol. You could
have a serious — or even fatal — accident if you drink
and drive or ride with a driver who has been drinking.
SeeDrunk Driving on page 4-2.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on with
the headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free your
vehicle when stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It Out on page 4-34.If your vehicle has a traction system, it can often help
to free a stuck vehicle. Refer to your vehicle’s traction
system in the Index. If the stuck condition is too
severe for the traction system to free the vehicle, turn
the traction system off and use the rocking method.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. The vehicle can overheat,
causing an engine compartment re or other
damage. Spin the wheels as little as possible
and avoid going above 35 mph (55 km/h) as
shown on the speedometer.
For information about using tire chains on your vehicle,
seeTire Chains on page 5-80.
4-33

Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good
deal longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal. Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
The arrows on your instrument panel will ash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also ash, telling other drivers
you’re about to turn, change lanes or stop.When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you don’t shift down,
you might have to use your brakes so much that they
would get hot and no longer work well.
You can tow in DRIVE (D). You may want to shift the
transmission to THIRD (3) or a lower gear, under heavy
loads or hilly conditions.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK (P) for a
few minutes before turning the engine off. If you do
get the overheat warning, seeEngine Overheating
on page 5-28.
