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.

3-3
(Defog): This setting divides the air between the
windshield and lower outlets with a small amount of air
directed toward the side window vents. This is useful
when fog appears on the windshield or side glass due to
rain or snowy conditions.
(Defrost): Use this setting to quickly remove fog or
frost from the windshield. This setting directs most of
the airflow to the windshield with a small amount of air
directed toward the lower and side window outlets.
Mode Buttons
These buttons control the air intake, the air conditioning
and the rear window defogger operation.
(Outside Air): Press this button and it will bring
outside air into the vehicle. The light on the button will
come on when operating. Use this setting while trying to
defrost or defog windows to help clear moisture.
(Recirculate): Press this button to limit the amount
of outside air entering the vehicle by recirculating most
of the air inside the vehicle. The light on the button will
come on when operating. This setting is helpful when
you are trying to cool the air quickly or to limit odors
entering the vehicle. Recirculate cannot be used while in
the defrost or defog modes.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.
A/C (Air Conditioning): This button turns the
air conditioning compressor off or on under most
conditions. The light on the A/C button comes on
when the compressor is operating. The air conditioning
does not operate at temperatures below approximately
35
F to 40
F (2
C to 4
C). The air conditioning
cools and dehumidifies the air coming into the vehicle.
The air conditioning cannot be turned off in defrost,
as it helps to remove moisture from the vehicle. It also
helps to keep the windows clear.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures.
See ªRear Window Defoggerº later in this section for
more information.

3-4 Automatic Electronic Dual Climate Control
System (Option)
Your vehicle may be equipped with an automatic
electronic dual climate control system. This system can
automatically adjust and control temperature output, fan
speed, air delivery mode, air conditioning operation and
air intake. You can use the AUTO (automatic) setting or
override the automatic operation with manual control
settings. The set temperature will be remembered each
time you turn the ignition off and restart in the same
settings. You can use the memory option to recall your
settings. SeeªMemoryº in the Index.Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the E/M button (English/Metric)
on the Driver Information Center (DIC). When you
start the vehicle, the display will show the current fan
speed, air delivery mode and the driver
-set temperature
for approximately five seconds and then show the
outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the 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. If you have
selected a manual fan speed, then the fan symbol will
appear on the display. If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.

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.

A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in
cold weather (below 32
F/ 0
C) and you have set the
driver temperature at 73
F (23
C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The fan
will start at a low speed. This is to avoid blowing cold
air into the vehicle. The length of the delay depends on
the amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.
As the interior of the vehicle warms up to the set
temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically defog
or bi
-level).A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather (above 80
F/ 27
C) and you have set the
driver temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The fan will
start at a low speed momentarily to push the hot air to
the floor of the vehicle and then go to a higher fan speed
with cold airflow out of the instrument panel outlets.
A small amount of airflow will continue through the
lower ducts to cool the floor area.
The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to the set temperature, the fan speed
will decrease and the temperature output may become
warmer. The air intake may shift from recirculation to
outside air mode. If the interior continues to cool due to a
decrease in the amount of heat the vehicle is absorbing
from the sun or a decrease in the outside temperature, the
system could switch to other air delivery modes (typically
bi-level or defog).

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.
