DVD Distortion
There can be an experience with audio distortion
in the wireless headphones when operating
cellular phones, scanners, CB radios, Global
Positioning Systems (GPS)*, two-way radios,
mobile fax, or walkie talkies.
It might be necessary to turn off the DVD player
when operating one of these devices in or near
the vehicle.

®System.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a
clean cloth and gently wipe the video screen.
Do not spray directly onto the screen and do not
press too hard or too long on the video screen.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen
to any of the sources: radio, 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 can listen to and control 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 is not able to
control the source. You can operate the rear
seat audio when the main radio is off.

When the radio and vehicle are turned off, the
blinking red light indicates that THEFTLOCK
®
is armed.

Radio Reception
Frequency interference and static during normal
radio reception can occur 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 boost 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.
301

FM Stereo
FM stereo gives the best sound, but FM signals
reach 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.
Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans
the bottom surface of the disc. If the surface of
a CD is damaged, such as cracked, broken,
or scratched, the CD does not play properly or
not at all. If the surface of a CD is soiled, take
a soft, lint free cloth or dampen a clean, soft cloth
in a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface.
Pick up CDs by grasping the outer edges or
the edge of the hole and the outer edge.
Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the lens
of the CD optics with lubricants internal to the
CD mechanism.
302

Fixed Mast Antenna
The xed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is
still tightened to the fender. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear
of snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the best
performance from the XM™ system if the sunroof
is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime
level. To change the volume level of the chime,
press and hold pushbutton 6 with the ignition
on and the radio power off. The volume level
will change from the normal level to loud,
and LOUD CHIME will appear on the radio display.
To change back to the default or normal setting,
press and hold pushbutton 6 again. The volume
level will change from the loud level to normal,
and NORMAL CHIME will appear on the
radio display. Removing the radio and not
replacing it with a factory radio or chime module
will disable vehicle chimes.
