CD/DVD MAINTENANCE
To keep a CD/DVD 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 (i.e. scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
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 “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.

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.
The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow, and they can be adjusted to direct
airflow where the occupant desires.

Defrost
Air is directed to the windshield through the
outlets at the base of the windshield. Air is also
directed to the front door windows through the side
window demister grilles. Some airflow is delivered to the
floor while in defrost so that comfort can be maintained.
Defrost/Floor
Air flows through the front and rear floor outlets
and the outlets at the base of the windshield. Air is
also directed to the front door windows through the
side window demister grilles. Some airflow is delivered
to the floor while in defrost so that comfort can be
maintained.
Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating areathrough vents under the front seats. Some airflow is
delivered to defrost while in the floor mode so that
comfort can be maintained.
Bi-Level
Air flows both through the outlets located in the
instrument panel and those located on the floor. Air
flows through the registers in the back of the center
console, and under the front seats to the rear seat
passengers. These registers can be closed to partially
block airflow. The center console outlets deliver condi-
tioned air while the floor outlets deliver heated air.
Panel
Air flows through the outlets located in the instru-
ment panel. Air flows through the registers in the
back of the center console to the rear seat passengers.
These registers can be closed to block airflow.

Recirculation
The recirculation feature can be selected with
the mode control knob. You may choose be-
tween Bi-Level Recirculation and Panel Recir-
culation air outlets while in this mode. Nor-
mally, air enters from outside the vehicle. However, when
in “Recirculation” mode air inside the vehicle is re-used.
Use this mode to rapidly cool the inside of the vehicle.
The “Recirculation” mode can also be used to tempo-
rarily block out outside odors, smoke, and dust.
Air Conditioning
To turn on the Air Conditioning, set the fan control
at any speed and press the snowflake button
located on the control panel. Conditioned air will
be directed through the outlets selected by the mode
control. A light in the snowflake button shows that the air
conditioning is on.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.
Automatic Temperature Control — If Equipped
The Automatic Temperature Control System automati-
cally maintains the interior comfort level desired by the
driver and passenger.
264 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:The numbers on the temperature dial represent
a comfort setting when the Mode knob is set to AUTO,
and not the actual air temperature.
Turn the mode control (on the right) knob to AUTO, and
then turn the blower control (on the left) knob to either
LO AUTO or HI AUTO. The LO AUTO position shouldbe used for front seat occupants only. The HI AUTO
position should be used when more airflow is desired, or
when rear seat occupants are present. Dial in the comfort
setting you would like the system to maintain by rotating
the driver’s or passenger’s control knob. Once the com-
fort level is selected, 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 will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF (O) position on the blower control knob stops the
system completely.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. How-
ever, if the driver and/or passenger temperature knobs
are set to the full hot or full cold positions, the air
temperature out of the ducts will be full hot or full cold

respectively. With the temperature setting in these posi-
tions, the system does not attempt automatic comfort
control.
Air Conditioning
The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary.
Recirculation
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in “Recirculation”
mode. This can be used when outside condi-
tions such as smoke, odors, dust, or high humidity are
present. This will cause the LED to illuminate.NOTE:
•The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.
•To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
•Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
266 UNDERSTANDING YOUR INSTRUMENT PANEL

•Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the “Recirculation” button. How-
ever, under certain conditions in automatic the system
is blowing air out of the defrost vents. When these
conditions are present, and the “Recirculation” button
is pressed, the indicator will flash and remain off. This
tells you that you are unable to go into Recirculation
mode at this time. If you would like to go to Recircu-
lation mode, you must first move your mode knob to
Panel, Panel/Floor, or Floor, then press the “Recircu-
lation” button. This feature will reduce the possibility
of window fogging.Manual Operation
This system offers a full complement of manual override
features which consist of Blower Preferred Automatic,
Mode Preferred Automatic with Manual Air Temperature
Control, and Manual. This means the customer can
override the blower, mode, and disable the Automatic
Temperature Control completely.
NOTE:Please read the Automatic Temperature Control
Operation Chart below for details.
