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.

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.

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

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.
