Preprogrammed Playlists
Preprogrammed playlists that were created using
WinAmp™, MusicMatch™, or Real Jukebox™ software
can be accessed, however, they cannot be edited
using the radio. These playlists are treated as special
folders containing compressed audio song les.
Playing an MP3/WMA (In Either the DVD or
CD Slot)
Insert a CD-R or CD-RW partway into either the top or
bottom slot, label side up. The player pulls it in, and
the CD-R or CD-RW should begin playing.
Depending on the format of the disc, a softkey menu
appears and allows navigation of the disc. The
menu reads left to right as RDM (Randomize song play
order), a Folder icon with left and right arrows (to
move up or down through available folders), a PL tag if
the disc has a Playlist available, and a Music Navigator
tag. If a Playlist tag is shown, toggling this key brings
up a Folder softkey only or the menu as previously
described.
If you turn off the ignition or radio with a CD-R or
CD-RW in the player it stays in the player. When you
turn on the ignition or radio, the CD-R starts to play
where it stopped, if it was the last selected audio source.
As each new track starts to play, the track number
and song title displays.
ZCD (Eject):Press and release this button to eject
the CD-R or CD-RW that is currently playing in the
bottom slot. A beep sounds and Ejecting Disc displays.
Once the disc is ejected, Remove Disc displays. The
CD-R or CD-RW can be removed. If the CD-R or
CD-RW is not removed, after several seconds, the CD-R
or CD-RW automatically pulls back into the player.
If loading and reading of a CD cannot be completed,
such as unknown format, etc., and the disc fails to eject,
press and hold this button for more than ve seconds
to force the disc to eject.
ZDVD (Eject):Press and release this button to eject
the CD-R or CD-RW that is currently playing in the top
slot. A beep sounds and Ejecting Disc displays. Once the
disc is ejected, Remove Disc displays. The CD-R or
CD-RW can be removed. If the CD-R or CD-RW is not
removed, after several seconds, the CD-R automatically
pulls back into the player. If loading and reading of a CD
cannot be completed, such as unknown format, etc., and
the disc fails to eject, press and hold this button for more
than ve seconds to force the disc to eject.
f(Tune):Turn this knob to select MP3/WMA les on
the CD-R or CD-RW that is currently playing.

Rear Seat Entertainment (RSE)
System
Your vehicle may have a DVD Rear Seat Entertainment
(RSE) system. The RSE system works with the
vehicle’s audio system. The DVD player is part of the
front radio. The RSE system includes a radio with a DVD
player, a video display screen, audio/video jacks, two
wireless headphones, and a remote control. See
Radio(s) on page 3-84for more information on the
vehicle’s audio/DVD system.
Before You Drive
The RSE is designed for rear seat passengers only.
The driver cannot safely view the video screen
while driving and should not try to do so.
In severe or extreme weather conditions the RSE
system might not work until the temperature is within
the operating range. The operating range for the
RSE system is above−4°F (−20°C) or below
140°F (60°C). If the temperature of your vehicle is
outside of this range, heat or cool the vehicle until the
temperature is within the operating range of the
RSE system.
Parental Control
The RSE system may have a Parental Control feature,
depending on which radio you have. To start Parental
Control, press and hold the radio power button for more
than two seconds to stop all system features such
as: radio, video screen, RSA, DVD and/or CD. While
Parental Control is on, a padlock icon displays.
The radio can be turned back on with a single press of
the power button, but the RSE system will remain
under Parental Control.
To turn Parental Control off, press and hold the radio
power button for more than two seconds. The RSE
returns from where it was previously left and the padlock
icon disappears from the radio display.
Parental Control can also be turned off by inserting or
ejecting any disc, pressing the play icon on the
radio DVD display menu, or changing an ignition
position.

1. Slide the rear cover back on the remote control.
2. Replace the two batteries in the compartment. Make
sure they are installed correctly using the diagram
on the inside of the remote control.
3. Replace the battery cover.
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.
Problem Recommended Action

picture or sound.Check that the RSE video
screen is in the auxiliary
source mode.
Check the auxiliary input
connections at both
devices.

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. The brakes might not have time to cool
between hard stops. The 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 vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do,
the pedal could get harder to push down. If the
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 can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-4.Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When you start the engine and begin to drive away, ABS
will check itself. You might hear a momentary motor or
clicking noise while this test is going on. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
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 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/retailer for
service.

Driving in Water
{CAUTION:
Driving through rushing water can be
dangerous. Deep water can sweep your vehicle
downstream and you and your passengers
could drown. If it is only shallow water, it can
still wash away the ground from under your
tires, and you could lose traction and roll
the vehicle over. Do not drive through
rushing water.Heavy rain can mean ash ooding, and ood waters
demand extreme caution.
Find out how deep the water is before you drive through
it. If it is deep enough to cover the wheel hubs, axles,
or exhaust pipe, do not try it — you probably will not get
through. Also, water that deep can damage the axle
and other vehicle parts.
If the water is not too deep, drive slowly through it. At
faster speeds, water splashes on the ignition system and
your vehicle can stall. Stalling can also occur if you
get the tailpipe under water. And, as long as the tailpipe
is under water, you will never be able to start the
engine. When you go through water, remember that
when the brakes get wet, it may take you longer to stop.
SeeDriving in Rain and on Wet Roads on page 4-28
for more information on driving through water.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let the engine assist the brakes on a steep
downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. The brakes will have
to do all the work of slowing down and they
could get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Always have the engine running and your
vehicle in gear when you go downhill.
Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds
that let you stay in your own lane.
Top of hills: Be alert — something could be in your
lane (stalled car, accident).
Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.
SeeOff-Road Driving on page 4-12for information
about driving off-road.
