CASSETTE TAPE AND PLAYER MAINTENANCE
To keep the cassette tapes and player in good condition,
take the following precautions:
1. Do not use cassette tapes longer than C-90; otherwise,
sound quality and tape durability will be greatly dimin-
ished.
2. Keep the cassette tape in its case to protect from
slackness and dust when it is not in use.
3. Keep the cassette tape away from direct sunlight, heat
and magnetic fields such as the radio speakers.
4. Before inserting a tape, make sure that the label is
adhering flatly to the cassette.
5. A loose tape should be corrected before use. To rewind
a loose tape, insert the eraser end of a pencil into the tape
drive gear and twist the pencil in the required directions.Maintain your cassette tape player. The head and capstan
shaft in the cassette player can pick up dirt or tape
deposits each time a cassette is played. The result of
deposits on the capstan shaft may cause the tape to wrap
around and become lodged in the tape transport. The
other adverse condition is low or ªmuddyº sound from
one or both channels, as if the treble tone control were
turned all the way down. To prevent this, you should
periodically clean the head with a commercially available
WET cleaning cassette.
As preventive maintenance, clean the head about every
30 hours of use. If you wait until the head becomes very
dirty (noticeably poor sound), it may not be possible to
remove all deposits with a simple WET cleaning cassette.

COMPACT DISC MAINTENANCE
To keep the compact discs in good condition, take the
following precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch-
ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners,
or antistatic sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged, oversized, or have theft
protection encoding. Try a known good disc before
considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily ªclearº by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.

Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
The mode control (at the right of the
control panel) can be set in any of the
following positions:

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift intoNEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
NOTE:On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
