Tape Player
Pressing the top of the switch once will go to the next
selection on the cassette. Pressing the bottom of the
switch once will go to the beginning of the current
selection or to the beginning of the previous selection if it
is within the first 5 seconds of the current selection.

track on the CD. Pressing the bottom of the switch once
will go to the beginning of the current track or to the
beginning of the previous track if it is within one second
after the current track begins to play. If you press the switch up or down twice it plays the
second track, three times, it will play the third, etc.
The button in the center of the left hand switch has no
function in this mode.
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 “muddy” 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 “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.

Recirculation Modes (Panel or Bi-Level)
Select the recirculation modes when
the outside air contains smoke or
odors. This feature allows for recircu-
lation of interior air only. Air flows
through the panel outlets in this mode.
Air flows through the panel only or
through both the panel and floor vents
depending on the selected mode (panel vs bi-level).
Bi-Level
Outside air flows through the outlets located in the
instrument panel and at the floor.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.
Defrost
Outside air is primarily directed to the windshield
through the defroster outlets located at the base of the windshield, and the demister outlets located at the
edge of each side of the instrument panel.
Blower Control
The rotary knob on the left of the control
panel is the blower control. Turn the
knob clockwise to one of the four posi-
tions to obtain the blower speed you
desire. To turn the blower off, turn the
knob to the far left position.
Temperature Control
The rotary knob at the center of the
control panel controls the temperature
of the interior air. You can choose your
degree of comfort by rotating the
knob. The coldest temperature setting
is to the extreme left (blue region) and
the warmest setting is to the extreme
right (red region) of the rotation.

Recirculation Modes (Panel or Bi-Level)
Select the recirculation modes when
the outside air contains smoke, odors,
high humidity, or if rapid cooling is
desired. This feature allows for recir-
culation of interior air only. Air flows
through the panel only or through
both the panel and floor vents depend-
ing on the selected mode (panel vs bi-level).
NOTE: Selecting a “Recirculation Mode” mode does not
necessarily consume more fuel than normal A/C mode.
Panel
Outside air flows through the outlets located in the
instrument panel.
Bi-Level
Outside air flows through the outlets located in the
instrument panel and at the floor.
Floor
Outside air flows primarily through the floor out-
lets located under the instrument panel.

four positions to obtain the blower
speed you desire. To turn the blower
off, turn the knob to the far left posi-
tion.

Circulation
The cab is designed with features to promote outside air
circulation. There are grilles in the cab back panel. These
are air exhausters that provide the means for regular
exchange of cab air.
Side window demisters direct air flow specifically to the
window glass to help prevent interior fogging of the
glass. They are located in the extreme outside upper
edges of the instrument panel. The demisters also pro-
vide extra air ducts for circulation. They are in operation
whenever the Floor, Mix or Defrost modes are in use. To
remove frost from the side windows, it is best to use the
full defrost mode.
NOTE: When you turn off the engine you may hear a
hissing sound from under the hood for a short period of
time. This is a normal condition that occurs if the air
conditioning system has been on. It is not an indication of
a problem with the air conditioning system.
