Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the keyless entry transmitter,
do the following:
1. Insert a thin object, such as a coin, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery, positive (+)
side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter. See
“Resynchronization” following this information.
5. Check the operation of the transmitter.

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.
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 would not be covered by your warranty.
Keep the headphones stored in a cool, dry place.
