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).

3-11 Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning
to work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature control knob (on a
manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum cooling is required.
When the air conditioning is on, you may sometimes
notice slight changes in the vehicle's engine performance
and power. This is normal. The system is designed to
help fuel economy while maintaining the desired
cooling level.
The air conditioning removes moisture from the air,
so you may notice water dripping from under the
vehicle when it is idling or after it has been turned off.
This is normal.
Heating
The heater works best if you keep the windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob
(on a manual climate control system) is all the way in
the red area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum heating is required.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
The bi
-level setting will direct cooler airflow to your
upper body and warmer air to the floor area.
If you have the optional engine coolant heater and use it
during cold weather 0
F (
-18
C) or lower, the heating
system will provide heat more quickly because the
coolant is already warmed. See ªEngine Coolant Heaterº
in the Index.

The Active Handling System comes on automatically
whenever you start your vehicle. To help maintain
directional control of the vehicle, you should always
leave the system on. You can turn the system off if you
ever need to. If you turn the Active Handling System
off, the Traction Control System will also be turned off.
Adjust your driving accordingly.
To turn the system off, press
the ACTIVE HANDLING
button on the console. You
can turn the system on and
off at any time by pressing
the button. The DIC will
display the appropriate
message when you push
the button.
Competitive Driving Mode
The driver can select the optional handling mode by
pressing the ACTIVE HANDLING button on the
console for more than five seconds. Competitive
Driving mode allows the driver to have full control of
the rear wheels while the Active Handling System
helps steer the vehicle by selective brake application.
The instrument cluster light will not be on. The Traction
Control System will not be operating. Adjust your
driving accordingly.
When you press the ACTIVE HANDLING button
again, or turn the ignition to ACC, the Active
Handling and Traction Control Systems will be on.
The TRAC/ACT HNDLG
-ON message will be
displayed temporarily in the DIC and a chime will
be heard.
