F
(132
C) or rises rapidly, this message is displayed.
The transmission may shift gears or apply the torque
converter clutch to reduce the fluid temperature.
Driving aggressively or driving on long hills can cause
the transmission fluid temperature to be higher than
normal. If this message appears, you may continue to
drive at a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230
F (110
C). The transmission fluid temperature
can be monitored with the GAGES button on the DIC.
See ªAutomatic Transmission Fluidº in the Index.
You should also check the engine coolant temperature.
If it is also hot, see ªEngine Overheatingº in the Index.If the HIGH TRANS TEMP message is displayed during
normal vehicle operation on flat roads, your vehicle may
need service. See your dealer for an inspection.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message
is displayed, the system is not working. Adjust your
driving accordingly.
ACTIVE HANDLING: Your vehicle is equipped with
a computer controlled system to assist the driver in
controlling the vehicle in difficult driving conditions.
You may feel or hear the system working and see the
ACTIVE HANDLING message displayed in the DIC.
This is normal when the system is operating. Also see

Comfort Controls
This section tells you how to make your air system work
for you.
With these systems, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Manual Comfort Controls
Fan Knob
(Fan): The left knob controls the force of air you
want. Turn the knob clockwise to increase fan speed or
counterclockwise to decrease fan speed. The fan must be
turned on for the air conditioning compressor to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it counterclockwise
(toward the blue area) for cooler air. Turn it clockwise
(toward the red area) for warmer air.
Mode Knob
The right knob selects the location of where the air will
enter the vehicle.
(Vent): This setting directs most of the air through
the instrument panel outlets with a very small amount of
air directed to the lower outlets.
(Bi-Level): This setting directs air into the vehicle
in two ways. Cooler air is directed toward your upper
body through the instrument panel outlets, while warmer
air is directed through the lower outlets.
(Floor): This setting directs most of the air through
the lower ducts to the floor area of the vehicle with
some of the air also directed toward the windshield and
side window vents.

3-5
Driver Set Temperature Knob
The DRIVER knob changes the temperature on
the driver's and passenger's side of the vehicle.
Turn the knob clockwise to increase the temperature
and counterclockwise to decrease the temperature.
Whenever you turn this knob, the temperature will be
displayed for approximately five seconds along with
the current fan speed and air delivery mode.
When adjusting the temperature, start with a driver
-set
temperature of 73
F (23
C) until you determine
your comfort zone. If you choose 60
F (16
C),
the system will remain at maximum cooling and will
not automatically adjust fan speed or air delivery.
If you choose 90
F (32
C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has
no effect on the operation of the system.Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob clockwise for warmer
air on the passenger's side, counterclockwise for cooler
air. If the driver
-set temperature is set at 60
F (16
C) or
90
F (32
C), turning the passenger knob has no effect
because the system is locked at a maximum setting.
Automatic Operation
Press the AUTO button to place the entire system in
the automatic mode. After a five
-second display of the
current settings, only the word AUTO and the outside
temperature will be shown on the digital display
unless you are in full cold 60
F (16
C) or full hot
90
F (32
C), then the word AUTO will not display.
The system will operate to achieve your comfort set
temperature as quickly as possible. The AUTO control
system works best with the windows up and the
removable roof installed or the convertible top up.

3-7
Manual Settings
With the automatic electronic dual climate control
system, there are several manual settings you can use
to control the system and override the AUTO operation.
You can program the fan speed, air delivery mode, air
intake mode and control the air conditioning operation
using these settings. The system will still determine the
temperature output level based on the driver
-set
temperature and the passenger temperature offset.
(Fan Speed): Press the button with the fan symbol
on it to manually lock in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete AUTO from the digital display.
The fan graphics with the fan speed bars will be shown.
To increase the fan speed so that more air flows into
the vehicle, press the up arrow on the fan switch.
To decrease the fan speed and airflow, press the down
arrow. The AUTO button must be pressed to return
to the automatic fan control.MODE: Press the MODE button to manually lock in
the current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.
(Vent): This setting directs most of the air through
the instrument panel outlets and a very small amount to
the lower outlets.
(Bi-Level): This setting directs air into the vehicle
in two ways. Cooler air is directed toward your upper
body through the instrument panel outlets, while warmer
air is directed through the lower outlets.
(Floor): This setting directs most of the air to the
floor area and some of it toward the windshield and side
window vents.
(Defog): This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears on the windshield or side glass due to rain or
snowy conditions.

3-8
Function Buttons
These buttons control the climate control ON/OFF,
air intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system. This is the only setting that fully
shuts off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air intake mode while in OFF.
A/C (Air Conditioning): This button turns
the air conditioning compressor off or on under most
conditions. The light on the A/C button will come on
when the compressor is operating in either the automatic
or manual mode. The air conditioning does not operate
at temperatures below approximately 35
F to 40
F
(2
C to 4
C). The light on the A/C button will flash if
pressed when air conditioning is not available. The air
conditioning cools and dehumidifies the air coming into
the vehicle. The air conditioning cannot be turned off in
defrost and defog, as it helps to remove moisture from
the vehicle. It also helps to keep the windows clear.If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures.
(Outside Air): Press this button to provide outside
air. The light on this air intake button will come on to
show when it is operating. When in the AUTO mode,
the system automatically selects outside air instead of
recirculate, as required, to control the temperature in the
vehicle. By pressing outside air, the system will lock
into the outside air mode. Any adjustment to the air
intake must then be made manually. Outside air should
be used when trying to defrost or defog windows to help
reduce moisture inside of the vehicle.

3-9
(Recirculate): Press this button to limit the
amount of outside air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. Recirculate is helpful when you are trying to
cool the air quickly or trying to limit odors and dust
from entering the vehicle. When in the AUTO mode,
the system automatically selects recirculate to cool the
vehicle's temperature. By pressing this button, the
system will lock into the recirculated air mode.
Any adjustment to the air intake must then be made
manually. Recirculation is not available when using the
defrost or defog mode because outside air is needed to
reduce moisture inside of the vehicle.
Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the defog or defrost mode and increase
the fan speed. To avoid re
-fogging of the windows,
operate the system in the outside air mode.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield.
This setting directs most of the airflow to the windshield
and a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in outside air.
If the system is in front defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in outside air.
See ªRear Window Defoggerº later in this section for
more information.

3-10 Sensors
The automatic electronic dual climate control system
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of
the instrument panel.
The sensor monitors the sun's solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.
Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor is
used for the outside air temperature readings shown on the
digital display for the automatic climate control system.If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature
display is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor
to receive information, so if you block or cover it,
the system will not function properly.
