that are used for your viewing entertainment, as
damage may result. SeeCare of the CD and
DVD Player on page 300andCare of Your CDs
and DVDs on page 299in this manual for
more information.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen
to any of the sources: radio, cassette tapes, or
CDs. 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 or CDs 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.

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 SIGNAL to indicate
interference.
Care of the Cassette Tape Player
A tape player that is not cleaned regularly
can cause reduced sound quality, ruined
cassettes, or a damaged mechanism. Cassette
tapes should be stored in their cases away
from contaminants, direct sunlight, and extreme
heat. If they are not, they may not operate properly
or may cause failure of the tape player.
297

The tape player should be cleaned regularly after
every 50 hours of use. The radio may display
CLEAN to indicate that the tape player has been
used for 50 hours without resetting the tape
clean timer. If this message appears on the
display, the cassette tape player needs to be
cleaned. It will still play tapes, but it should
be cleaned as soon as possible to prevent damage
to the tapes and player. If there is a reduction in
sound quality, try a known good cassette to
see if the tape or the tape player is at fault. If this
other cassette has no improvement in sound
quality, clean the tape player.
For best results, use a scrubbing action,
non-abrasive cleaning cassette with pads which
scrub the tape head as the hubs of the cleaner
cassette turn. The recommended cleaning cassette
is available through your dealer.When cleaning the cassette tape player with the
recommended non-abrasive cleaning cassette, it is
possible that the cassette may eject, because
the cut tape detection feature on the radio
may recognize it as a broken tape, in error. To
prevent the cleaning cassette from being ejected,
use the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE DISC button for
ve seconds. READY will appear on the
display and the cassette symbol will ash for
ve seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the
manufacturer’s recommended cleaning time.
When the cleaning cassette has been
ejected, the cut tape detection feature
will be active again.
298

A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. This type of cleaning cassette
will not eject on its own. A non-scrubbing action
cleaner may not clean as thoroughly as the
scrubbing type cleaner. The use of a non-scrubbing
action, dry-type cleaning cassette is not
recommended.
After the player is cleaned, press and hold the
eject button for ve seconds to reset the CLEAN
indicator. The radio will display --- or CLEANED to
show the indicator was reset.
Cassettes are subject to wear and the sound
quality may degrade over time. Always make sure
the cassette tape is in good condition before
the tape player is serviced.Care of Your CDs and DVDs
Handle CDs and DVDs carefully. Store them in
their original cases or other protective cases and
away from direct sunlight and dust. The CD
and DVD player scans the bottom surface of the
disc. If the surface of a CD or DVD is damaged,
such as cracked, broken, or scratched, the CD or
DVD will not play properly or not at all. If the
surface of a CD or DVD 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. If a dampened
cloth was used to clean the disc, dry it with a
dry cotton cloth.
Do not touch the bottom side of a CD or DVD
while handling it; this could damage the surface.
Pick up CDs or DVDs by grasping the outer edges
or the edge of the hole and the outer edge.
299

Care of the CD and DVD Player
The use of CD or DVD lens cleaners for CDs or
DVDs are not advised, due to the risk of
contaminating the lens of the CD optics with
lubricants internal to the CD or DVD mechanism.
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.
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.
If your vehicle has a sunroof, the performance of
the XM™ system may be affected 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.
