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.
162 UNDERSTANDING YOUR INSTRUMENT PANEL

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.
CD/DVD DISC MAINTENANCE
To keep the CD/DVD 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, paper CD labels, or tape to the
disc; avoid scratching the disc.
4. Do not use solvents such as benzine, 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.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance 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 repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Air Conditioning
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.
Air conditioning can be obtained by depressing the
ªA/Cº button on the control panel and setting the
appropriate rotary knobs to obtain the desired comfort
level.
164 UNDERSTANDING YOUR INSTRUMENT PANEL

Blower Control
The rotary knob on the left
controls the blower and can
be set in one of four positions
from LO to HI.The blower
fan motor will remain on un-
til the system is turned to the
OFF position or the ignition
is turned OFF.
Temperature Control
The degree of comfort can be
selected by rotating the tem-
perature control knob in the
center. The coldest tempera-
ture setting is on the extreme
left and the warmest setting
on the extreme right of the

Mode Selection
The mode selector (the right
rotary knob) can be set in any
of the following positions:
OFF
This position turns off the blower motor and outside air
will not pass through any outlets.
Recirculation
The recirculation feature can be selected with the
mode control knob. Outside air is normally
drawn into the vehicle in all of the other modes, such as
panel air, bi-level, floor, floor/defrost, and the defrost airdistribution outlets. Air flows through the outlets located
in the instrument panel. Use this mode to rapidly cool the
inside of the vehicle. The Recirculation mode can also be
used to temporarily block out outside odors, smoke, and
dust.
Panel
Air flows through the outlets located in the instru-
ment panel.
Bi-Level
Air flows both through the outlets located in the
instrument panel and those located on the floor.
Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating area
through vents under the front seats.
166 UNDERSTANDING YOUR INSTRUMENT PANEL

Defrost/Floor
Air flows through the front and rear floor outlets
and the outlets at the base of the windshield.
Defrost
Air is directed to the windshield through the
outlets at the base of the windshield.
NOTE:To improve fuel economy, leave in defrost only
when necessary.
Infrared Dual-Zone Climate Control Ð If Equipped
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by using
a dual infrared sensor located in the face of the control
unit. The dual infrared sensor independently measures
the surface temperature of the driver and passenger.
Based on the sensor input, the system automatically
adjusts the air flow temperature, the air flow volume, andamount of outside air recirculation. This maintains a
comfortable temperature even under changing condi-
tions.
Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO. Dial in the temperature
you would like the system to maintain by rotating the
driver's or passenger's control knob. Once the comfort
UNDERSTANDING YOUR INSTRUMENT PANEL 167

level is displayed the system will maintain that level
automatically using the heating system. Should the de-
sired comfort level require air conditioning, the system
will automatically make the adjustment.
You may notice the blower speed getting lower as the
difference between the driver and passenger temperature
settings gets larger. This is an extreme condition and the
airflow may not perform as anticipated.
The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the ªOverhead Console-Customer Program-
mable Featuresº in Section 3 of this manual.
The left knob controls the blower fan. Within the AUTO
setting on this control, you can select a HI volume of air
from the blower or a LO volume. Once the system is set
up for your comfort level, it is not necessary to change
the setting. You will experience the greatest efficiency by
simply allowing the system to function automatically.Manual Operation
However, this system does offer a full complement of
manual override features. There is a manual blower
range used when the AUTO setting is not desired. The
left control can be set to any fixed blower speed by
rotating the knob from LO to HI on the upper portion of
the dial.
The operator can override the AUTO mode setting and
select the direction of the air by rotating the right mode
knob to one of the following positions.
²Defrost
Air is directed to the windshield through the
outlets at the base of the windshield.
²Defrost/Floor
Air flows through the front and rear floor outlets
and the outlets at the base of the windshield.
168 UNDERSTANDING YOUR INSTRUMENT PANEL

²Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating
area through vents under the front seats.
²Bi-Level
Air flows both through the outlets located in the
instrument panel and those located on the floor.
²Panel
Air flows through the outlets located in the in-
strument panel.
²OFF
This position turns off the entire system.
Depress the A/C button to turn on and off the air
conditioning during manual operation only. Conditioned
outside air is then directed through the outlets selected
on the mode control dial.When the outside air contains smoke, odors, high humid-
ity, or if rapid cooling is desired you may wish to
recirculate interior air by pressing the ªRecirculateº icon
button. The recirculation mode should only be used
temporarily. The light on the A/C and ªRecirculateº icon
buttons will illuminate when these buttons are selected.
You may use these features separately or with one
another. Push in on the buttons a second time to change
the functions.
NOTE:If the interior of the windows begins to fog,
press the ªRecirculateº icon button to return to outside
air. Some temp./humidity conditions will cause captured
interior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow ªRecircu-
lateº to be selected while in the defrost or defrost/floor
modes.
To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
UNDERSTANDING YOUR INSTRUMENT PANEL 169

off until the engine warms up. However, the fan will
engage immediately if the defrost mode is selected or if
you select a fixed blower speed.
Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, use the A/C,
panel, and blower controls. Direct the panel outlets
toward the side windows. Recirculate without A/C
should not be used for long periods as fogging may
occur. Interior fogging on the windshield can be quickly
removed by using the defrost mode.
REAR WINDOW FEATURES
Rear Window Wiper/Washer
A switch on the right side of the steering column controls
operation of the rear wiper/washer function. Rotating
the center of the switch up to the DEL (Delay) position or
the ON position will activate the wiper. Push the lever
forward to initiate the wash function in any of the threepositions. The wash pump will continue to operate as
long as the button is pressed. Upon release, the wipers
will cycle three times before returning to the set position.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the ªParkº
position.
