Air Conditioning Operation
To turn the air conditioning On or Off perform the
following steps:
²Position the mode control button to the desired airflow
setting.
²Set the front blower control to any desired speed.
²Press the Snowflake (A/C) button which is located to
the right of the temperature control slide. An indicator
light on the Snowflake (A/C) button shows that the air
conditioning is On.
²Press the Snowflake (A/C) button a second time to
turn the air conditioning Off.
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes inengine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Front Blower Control
The Front Blower controls the
amount of air delivered to the
passenger compartment.
There are four blower speeds.
The fan speed increases as
you turn the control clock-
wise. When the front blower
control is turned to OFF, the
blower will be turned off and
the system will be positioned
in recirculation mode.

Automatic Control
The ATC system can maintain a steady comfort level in
various weather conditions with a simple operation:
²Select your desired temperature setting by pressing
the + or - side of the TEMP rocker switches. A digital
temperature setting for driver and passenger will be
displayed. The ATC system uses an infrared sensor
located in the overhead console to measure the tem-
perature of the driver and passengers. Based on the
sensor input, the system will automatically control
comfort by varying the temperature, fan speed, and
mode. This maintains a comfortable temperature, even
under changing conditions. It is important that objects
are not blocking the infrared sensor. It is also impor-
tant that objects are not used that may scratch or
damage it in any way.
Level Of Automatic Control
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. It is
not necessary to move the temperature setting for cold or
hot vehicles. The system automatically adjusts the tem-
perature, mode and fan speed to provide comfort as
quickly as possible.
NOTE:In cold weather, the fan will not turn on in
AUTO mode until the engine coolant has warmed up
sufficiently. This is indicated by the WARM UP DELAY
message on the display.
NOTE:The temperature can be displayed in U.S. or
Metric by selecting the US/M customer programmable

feature. Refer to the9Overhead Console-Customer Pro-
grammable Features.9The mode will also be shown in the
display and will change as required during automatic
operation.
NOTE:The system can be put into recirculate mode
without affecting ATC operation. This will prevent out-
side air from entering the vehicle. Use this mode to
temporarily block out any outside odors, smoke, or dust.
Manual Control (ATC)
You also may choose to customize your comfort by
selecting the fan speed and mode manually. Turning the
fan speed knob or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or - TEMP rocker switches.
FAN Control
Use this knob to regulate the amount of air delivered
through the system in any mode you select. Rotation
of the knob to increase (clockwise) or decrease (counter-
clockwise) fan speed.
Air Conditioning Operation
Press this button to enable the air conditioning
system. Compressor operation is automatic when
you press the AUTO button and no snowflake is
shown. A snowflake indicates that the A/C system is
enabled. The snowflake will not be displayed in AUTO
mode even though the A/C system is enabled.
The compressor may operate at any temperature above
32ÉF (0ÉC).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in
258 INSTRUMENT PANEL AND CONTROLS

engine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.
Manual control of Recirculation is possible only in Panel,
Floor, and Bi-Level modes. It will not operate in Mix, or
Defrost modes. The recirculation symbol will flash three
times indicating recirculation is not available in these
modes.NOTE:If the interior of the windows begin to fog, press
the recirculate button to return to outside air. Some
conditions will cause captured interior air to fog win-
dows when in recirculate mode.
Panel
Air flows through the outlets located in the instru-
ment panel. These outlets can be adjusted to direct
the airflow.
Floor (Heat)
Air flows primarily through the floor outlets lo-
cated under the instrument panel. A small amount
of air is directed through the defrost and side window
demister outlets.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.

If the rear wiper is operating when the ignition is turned
off, the wiper will automatically return to the ªParkº
position. When the vehicle is restarted, the wiper will
resume operation.
Rear Window Defrosting
A push-button type switch is located in the climate
control panel. Press the switch and the rear win-
dow defroster and electric remote control heated mirrors
(if equipped) will turn On. An amber indicator on the
push-button will light when the defroster is turned On.
An symbol will be displayed when the defroster is turned
on with an ATC control. Push again to turn Off prior to
time-out. The defroster will automatically turn Off after
fifteen minutes. For ten more minutes of operation, push
the button again. To prevent excessive battery drain, use
the defroster only when the engine is operating.
CAUTION!
Use care when washing the inside of the rear window
to prevent damage to heating elements. Use a soft
cloth and a mild washing solution, wiping parallel to
the heating elements. Also, keep all objects a safe
distance from the window to prevent damaging the
heating elements.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Be sure to turn off the engine and remove the key
from the ignition switch if you want to rest or sleep
in your car. Accidents can be caused by inadvertently
moving the gear selection lever or by pressing the
accelerator pedal. This may cause excessive heat in
the exhaust system, resulting in overheating and
vehicle fire which may cause serious or fatal injuries.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Automatic Transmission
Start the engine with the selector lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
Normal Starting of either a warm or cold engine is
obtained without pumping or depressing the accelerator
pedal.
STARTING AND OPERATING 273

Tip Start Feature
Your vehicle has a ªTip Startº starting system. With ªTip
Startº the driver does not need to hold the key in the
'Start' position until the vehicle starts, but can release the
key (still in the ignition) and the vehicle will continue
through the start cycle.
²Turn the ignition key to the START position, until the
start motor engages.
²Release the key (still in the ignition) and the starter
will continue through the start cycle until the vehicle
starts or for 5 seconds (whichever comes first).
If Engine Fails To Start
If the engine fails to start after you have followed the
Normal Starting procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while cranking the engine. This should clear any excess
fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
