3-32 Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the fender.
Backglass Antenna (If Equipped)
Your AM-FM antenna is integrated with your rear
window defogger, located in the rear window. Be sure
that the inside surface of the rear window is not
scratched and that the lines on the glass are not
damaged. If the inside surface is damaged, it could
interfere with radio reception. Also, for proper radio
reception, the antenna connector at the top
-center of the
rear window needs to be properly attached to the post on
the glass.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio's
ability to pick up stations clearly. The repairs
wouldn't be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.

If you choose to add a cellular telephone to your vehicle,
and the antenna needs to be attached to the glass, be sure
that you do not damage the grid lines for the AM
-FM
antenna. There is enough space between the lines to
attach a cellular telephone antenna without interfering
with radio reception.
On cars equipped with the rear window defogger and built
-in
antenna, the defogger grid serves as a radio antenna. If you
have this feature on your car, do not apply aftermarket glass
tinting to the back glass. The metallic film in some tinting
materials will interfere with or distort the incoming radio
reception. Care must be taken when cleaning the rear
window because breaks in the resistive material heating
element will adversely affect radio performance and
defogger performance. See your dealer for details.
Diversity Antenna System (If Equipped)
Your AM-FM antennas are located in the front
windshield and rear window. Be sure that the inside
surfaces of the front windshield and rear window are not
scratched and that the lines on the glass are not
damaged. If the inside surfaces are damaged, they could
interfere with radio reception. Also, for proper radio
reception, the antenna connector at the top
-center of the
front windshield and the antenna connector at the
top
-center of the rear window need to be properly
attached to the posts on the glass.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio's
ability to pick up stations clearly. The repairs
wouldn't be covered by your warranty.
If, when you turn on your rear window defogger, you
hear static on your radio station, it could mean that a
defogger grid line has been damaged. If this is true, the
grid line must be repaired.
If you choose to add an aftermarket cellular telephone to
your vehicle, and the antenna needs to be attached to the
glass, be sure that you do not damage the grid lines for
the AM
-FM antennas or place the cellular telephone
antenna over the grid lines.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put your automatic
transaxle in PARK (P) before setting the
parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlet. Turn off all lamps
that aren't needed as well as radios. This will avoid
sparks and help save both batteries. In addition, it
could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Open the hoods and locate the batteries. (Your
vehicle's battery is located toward the front of the
passenger's side of the vehicle's engine, under a
diagonal brace.)
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
