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 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.
280

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.
Both sets of rear seat headphones may include
foam ear pads that can be replaced.
Foam ear pads on these headphones may
become worn or damaged. The headphone foam
ear pads can become damaged if they are not
handled or stored properly. If the foam ear pads do
become damaged or worn out, the pads can be
replaced separately from the headphone set.
It is not necessary to replace the complete
headphone set.
The headphone replacement foam ear pads can
be ordered in pairs. See your dealer for more
information.Battery Replacement
To change the batteries, do the following:
1. Loosen the screw on the battery compartment
door located on the left side of the headphone
earpiece.
2. Replace the two AAA batteries in the
compartment. Make sure that they are
installed correctly, using the diagram on the
inside of the battery compartment.
3. Tighten the screw to close the
compartment door.
If the headphones are to be stored for a long
period of time, remove the batteries and keep them
in a cool, dry place.
282

The RSE system will always transmit the audio
signal by infrared to the wireless headphones,
if there is audio available. See “Headphones”
previously for more information.
The RSE system is capable of outputting audio to
the vehicle speakers by using the radio. The
RSE system may be selected as an audio source
on the radio if the RSE system power is on.
Once the RSE system is selected as an audio
source on the radio, adjust the speaker volume on
the radio, if necessary. If the RSE system power
is not on, the RSE system will not be an available
source on the radio. Refer to the radio information
for the radio that your vehicle has for more
information.
The RSE system is capable of outputting audio to
the wired headphone jacks on the rear seat
audio system (if equipped). The RSE system may
be selected as an audio source on the rear
seat audio system if the RSE system power is on.

Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen
to any of the sources: radio, cassette tapes,
CDs, or DVDs. However, the rear seat passengers
can only control the sources that the front seat
passengers are not listening to. For example, rear
seat passengers may listen to and control
cassette tapes, CDs, or DVDs through the
headphones while the driver listens to the radio
through the front speakers. The rear seat
passengers have control of the volume for each
set of headphones.
The front seat audio controls always have priority
over the RSA controls. If the front seat
passengers switch the source for the main radio to
a remote source, the RSA will not be able to
control the source. You can operate the rear seat
audio when the main radio is off.
P(Power):Press this button to turn the system
on or off. The rear speakers will be muted
when the power is turned on.
u(Volume):Turn this knob to increase or to

Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet.
If there is interference or static, unplug the item
from the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can cause
station frequencies to interfere with each other.
For better radio reception, most AM radio stations
boosts the power levels during the day, and then
reduce these levels during the night. Static can also
occur when things like storms and power lines
interfere with radio reception. When this happens,
try reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals
reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
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 can cause
loss of the XM™ signal for a period of time.
The radio could display NO XM SIGNAL to indicate
interference.
