Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the liftgate or
liftglass open because carbon monoxide (CO)
gas can come into your vehicle. You cannot
see or smell CO. It can cause
unconsciousness and even death. If you must
drive with the liftgate open or if electrical
wiring or other cable connections must pass
through the seal between the body and the
liftgate or liftglass:
Make sure all other windows are shut.
Turn the fan on your climate control
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See “Climate Control
System” in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-34.
Liftgate Release
To unlock the liftgate, use the power door lock switch or
the remote keyless entry transmitter. SeeRemote
Keyless Entry System Operation on page 2-6. The
liftglass will also unlock when the liftgate is unlocked.
Press the button on the liftglass to open it. To open the
entire liftgate, lift the handle located in the center of
the liftgate. When the liftgate is opened, the liftglass will
lock after a short delay.
Emergency Release for Opening
Liftgate
1. Remove the trim plug, located on the inside of the
liftgate in the center, to expose the access hole in
the trim panel.
2. Use a tool to reach through the access hole in the
trim panel.
3. Pry the left release lever up to the unlock position.
Pry the right release lever up to unlatch the liftgate.

To store the memory settings, do the following:
1. Adjust the driver’s seat, including the seatback
recliner and lumbar, both of the outside mirrors,
and the adjustable pedals, if equipped, to the
desired position.
SeeAdjustable Throttle and Brake Pedal on
page 2-22for more information.
2. Press and hold the 1 or 2 button of the memory
control for three seconds. A double chime will
sound to let you know that the position has
been stored.
To repeat the procedure for a second driver, follow the
preceding steps, but press the other numbered
memory control button.
To recall the memory settings, do one of the following:
Press and release button 1 or 2 while the vehicle
is in PARK (P). A single chime will sound and
the memory position will be recalled.
If programmed to do so through the Driver
Information Center (DIC), pressing the unlock button
on the remote keyless entry transmitter will recall
the preset driver’s memory seat, mirrors, and
adjustable pedals position. The numbers on the
back of the transmitters, 1 or 2, correspond to the
numbers on the memory controls.
If programmed to do so through the DIC, placing
the key in the ignition will recall the driver’s
memory seat, mirrors, and adjustable pedals
positions.
See “Seat Recall” underDIC Vehicle Customization on
page 3-60for more information.

any time, press one of the memory buttons or power
seat controls.

Listening to a DVD
If your vehicle has the Rear Seat Entertainment (RSE)
system and a DVD is playing, the DVD symbol will
appear on the radio display indicating that the DVD is
available and can be listened to through your vehicle’s
speakers.
To listen to the DVD, press the CD AUX button until
RSE appears on the radio display. The current
radio source will stop and the DVD sound will come
through the speakers.
To stop listening to the DVD, press the CD AUX button,
if a CD is loaded, or press the BAND button to select
a different source.
When the RSE system is turned off, the DVD symbol
will go off of the radio display and RSE OFF will appear
on the radio display. The radio will return to the last
radio source that you were listening to.
SeeRear Seat Entertainment System on page 3-124for
more information.
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 System
Your vehicle may have a 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.
3-124
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 will
display Parental Control ON and the power indicator
light on the DVD player will ash. It will also disable 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 may also be used to turn the DVD player
power on and automatically resume play if the ignition is
in RUN, ACCESSORY, or if RAP is active.
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 will not be covered by your warranty.
Keep the headphones stored in a cool, dry place.
