LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
present. Dial in the temperature you would like the
system to maintain by rotating the driver's or passenger's
control knob. Once the comfort level is selected the
system will maintain that level automatically using the
heating system. Should the desired 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 position on the fan control stops the system
completely and closes the outside air intake.
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation.The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause an audible beep and the LED will flash three
times and remain off. This indicates that the system is in
AUTO and requesting the air conditioning is not neces-
sary.
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode
(ten minutes). This can be used when outside
conditions such as smoke, odors, dust, or high humidity
are present. This will cause an audible beep, and the LED
will illuminate. After ten minutes the system will return
to normal AUTO mode function and the LED will turn
off.

NOTE:
²
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.
²To 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.
²Under 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.
Manual Operation
This system offers a full complement of manual override
features which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the customer can override
the blower, the mode, or both. 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.
NOTE:Please read the Automatic Temperature Control
Operation Chart below for details.

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. Air is
also directed to the front door windows through the
side window demister grilles.
²
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.
²
Floor
Air flows through the floor outlets located
under the instrument panel and into the rear
seating area through vents under the front seats.
²
Bi-Level
Air flows both through the outlets located in
the instrument panel and those located on thefloor. 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.
²
Panel
Air flows through the outlets located in the
instrument panel. Air flows through the regis-
ters in the back of the center console to the rear seat
passengers. These registers can be closed to block
airflow.
Depress this button to turn on and off the air
conditioning during manual operation only. Con-
ditioned outside air is then directed through the
outlets selected on the mode control dial. The button
includes an LED that illuminates when manual operation
is selected, and will cause an audible beep.
NOTE:To manually control the air conditioning the
mode selector must be moved out of the AUTO position.
Press this button to turn on the rear window
defroster and the heated side mirrors (if
equipped). An LED in the button will illuminate and an
audible beep indicates that the rear window defroster is

ON. The defroster automatically turns off after approxi-
mately 10 minutes of operation for the first push of the
button, and will turn off after approximately 5 minutes
for the second push of the button.
CAUTION!
To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.
Labels can be peeled off after soaking with warm
water.
This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The recirculation mode should only
be used temporarily. The button includes an
LED that illuminates, and an audible beep indicates that
the recirculation mode is active. You may use this feature
separately.
NOTE:Extended use of recirculation may cause the
windows to fog. 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 ham-
per visibility. For this reason, the system will not allow
ªRecirculateº to be selected while in the defrost or
defrost/floor modes. Attempting to use the recirculation
while in these modes will cause the LED in the button to
blink and then turn off.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.

Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
NOTE:See Operating Tips chart (for Manual A/C
Control) at the end of this section for suggested control
settings in different weather conditions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow and if they
enter the plenum they could plug the water drains. In
winter months make sure the air intake is clear of ice,
slush and snow.
A/C Air Filter Ð If Equipped
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to ªMaintenance Proceduresº in
your Owner's Manual for filter replacement instructions.

WARNING!
It is dangerous to shift the selector lever out of ªPº or
ªNº if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
Gear Ranges
P (Park)
Supplements the parking brake by locking the trans-
mission. The engine can be started in this range. Never
use P (Park) while the vehicle is in motion. Apply the
parking brake when leaving the vehicle in this range.
Always apply the parking brake first, and then place
the selector in P (Park) position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
shift lever is locked in the P (Park) position, securing
the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
²When shifting into P (Park) move the lever all the way
forward until it stops, and is fully seated.
²Look at the shift indicator display on the instrument
panel to ensure it is in the P (Park) position.
