Playing a Cassette Tape
The tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes
longer than that are so thin they may not work well in
this player. The longer side with the tape visible should
face to the right. If you hear nothing or hear a garbled
sound, the tape may not be in squarely. Press the eject
button to remove the tape and start over.
If the ignition and radio are off, press the eject button or

tape symbol will appear on the display and an arrow
showing which side of the tape is playing. The tape
player will play the other side of the tape when it
reaches the end.

of the music that has been recorded, and the way the
CD-R has been handled. There may be an increase
in skipping, difficulty in finding tracks, and/or difficulty in
loading and ejecting. If these problems occur, check

the CD will not play properly. If the surface of the CD is
soiled, seeCare of Your CDs on page 3-78for more
information.If there is no apparent damage, try a known good CD.

CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top
of the recorded CD with a marking pen instead.
Notice:If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any

period is complete, the player will sense an error and will
try to eject the CD several times before stopping.

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 five seconds to reset the CLEAN indicator.
The radio will display --- or CLEANED to show the
indicator was reset.

degrade over time. Always make sure the cassette tape
is in good condition before the tape player is serviced.
Care of Your CDs
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 will
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 Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the internal
lens of the CD optics with lubricants.
Fixed Mast Antenna
The fixed 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.
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 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 will
appear on the radio display. Each time the chime volume
is changed, three chimes will sound to indicate the
change. Removing the radio and not replacing it with a
factory radio or chime module will disable vehicle chimes.

Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
•Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system,
and transmission. These parts can work hard
on mountain roads.
{CAUTION:
If you do not shift down, your brakes could
get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash. Shift
down to let your engine assist your brakes on
a steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with
the ignition off is dangerous. Your brakes will
have to do all the work of slowing down. They
could get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Always have your engine running and your
vehicle in gear when you go downhill.
