²If the recirculation button is pressed while in the Mix
or Defrost mode, the indicator light in the recirculation
button will flash 3 times indicating that recirculation is
not allowed.
A/C Recirculation Programming
The recirculation control is programmed to cancel the
recirculation mode when the ignition key is turned OFF
and will reset to outside air mode when the ignition key
is turned ON. The frequent use of outside air will help
keep odors from building up within the air conditioner-
heater housing. It is recommended that the recirculation
mode be used as little as possible, especially in humid
climates.
For hot and dry climates, or people who are allergic to
pollen and find frequent use of the recirculation mode
necessary, the recirculation mode can be programmed to
not automatically reset to the outside mode by using the
following procedures:
²Turn the ignition switch to the OFF position.
²Set the mode control to ªPANELº.
²Depress and hold in the ªPOWERº button.
²Start the engine, and continue to hold in the ªPOWERº
button until the indicator light starts flashing repeat-
edly.
²Press the recirculation button until the indicator light
remains lit.
²The selection will be stored when the ignition switch is
turned OFF or if the ªPOWERº button is pressed.
If the recirculation indicator light is lit, the recirculation
mode will not reset when the engine is started. If the
recirculation indicator light is not lit, the recirculation
mode will reset to the outside air mode when the engine
is started. The programmed status can be changed back
and forth by following the above mentioned procedure.

When the system is set to your comfort level, it is not
necessary to change the settings. You will experience the
greatest efficiency by allowing the system to function
automatically. The system will operate fully automati-
cally in either9AUTO HI9or9AUTO LO9. The9AUTO
LO9setting will limit the maximum fan speed and should
be used when more quiet operation is desired. Use the
9AUTO HI9setting when the quickest cool-down or
warm-up performance is desired.
NOTE:
²It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
²The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.Refer to the ªElectronic Vehicle Information Center-
Customer Programmable Featuresº in Section 3 of this

glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
To insure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7, Maintenance
Procedures, of this manual for proper coolant selection.
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
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 adequatesystem lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, use the A/C
button to reduce the humidity inside the vehicle.
Fogging on the inside of the windshield can be quickly
removed by pressing the defrost button and increasing
the blower speed.
Do not use the Recirculation mode without the A/C
button for long periods as fogging may occur.
Outside Air Intake
Before driving, always make sure the air intake located
directly in front of the windshield is free of obstructions
such as leaves, ice, or snow, which could reduce airflow
and/or plug the water drain tube inside the plenum.

Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ACCESSORY or ON
position.
NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Reset Mode - Electronic Transmission
For electrical system malfunctions there is an override for
the interlock system. In order to override this system the
key must be in the ignition with the switch in the ACC or
ON positions. Pull up and rearward on the shifter bezel
ring.
The override can be activated by pressing the pink-
colored tab, which can be accessed through the lowerright corner of the shifter bezel ring. While the override is
pressed, the shifter can be moved out of the park position
without pressing the brake. After operation return the
shifter bezel ring to its original position.
NOTE:Even if the transmission can be reset, it is
recommended that you visit a dealer at your earliest

possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
ªPº Park
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never
attempt to use PARK while vehicle is in motion.
Apply parking brake when leaving vehicle in this range.
WARNING!
Never use Park position on an automatic transmission
as a substitute for the parking brake. Always apply
parking brake fully when parked to guard against
vehicle movement and possible injury or damage.
ªRº Reverse
Shift into this range only after the vehicle has come to a
complete stop.
ªNº Neutral
Engine may be started in this range.
ªDº Overdrive
To be used for most city and highway driving, it provides
smoothest upshifts and downshifts and best fuel
economy. When frequent transmission shifting occurs
while using the ªDº Overdrive position, such as when
operating the vehicle under heavy loading conditions,
(i.e. in hilly terrain, traveling into strong head winds or
while towing heavy trailers), use the AutoStick mode and
select the ª3º range.
NOTE:Using the ª3º range in the AutoStick mode
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.

AUTOSTICK
AutoStick is a driver-interactive transmission that offers
manual gear shifting capability to provide you with more
control. AutoStick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
AutoStickTOperation
By placing the selector lever one shift-level below the9D9
position, it can be moved from side to side. This allows
the driver to select a higher or lower range of gears.
Moving the selector lever to the Left (-) triggers a
downshift and to the Right (+) an upshift. The gear
position will display in the instrument cluster on the
transaxle range indicator.NOTE:In Autosticktmode, the transaxle will only shift
up or down when the driver moves the selector lever to
the Right (+) for shifting up or to the Left (-) when
shifting down.
AutoStickTGeneral Information
²
You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
²If a ratio other than 1st is selected, and the vehicle is
brought to a stop, the transaxle control logic will
automatically select the 1st gear ratio.
²Starting out in second gear is helpful in snowy or icy
conditions.
²Avoid using speed control when Autosticktis engaged.
²The transaxle will automatically shift up when maxi-
mum engine speed is reached while Autosticktis
engaged.
