Comfort Controls
This section tells you how to make your air system work
for you.
Climate Control Panel
Your vehicle is equipped with a dual-zone electronic
climate control system. This system can automatically
adjust and control temperature, fan speed, air delivery
mode, air conditioning operation and air intake. You can
use the AUTO (automatic) setting or override the
automatic operation by manually altering the settings.If your vehicle is equipped with the climate control
personalization feature, you will be able to program
your preferred climate control settings and recall them
using your remote keyless entry transmitter. See
ªClimate Control Personalizationº in the Index.
TEMP (Temperature): These knobs adjust the air
temperature coming through the system. Turn a TEMP
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Both TEMP knobs adjust from 60
F (16
C) to
90
F (32
C) independent of each other. It is
recommended that the passenger's setting stay no more
than four degrees warmer or cooler in temperature from
the driver's setting.

3-4
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. Press this button again
to turn off the recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.
Recirculation is not available in the defrost mode.
A/C (Air Conditioning): Press this button to turn the
air conditioning compressor on and off. The system will
cool and dehumidify the air inside the vehicle.
When the compressor is off, A/C OFF appears on the
climate control panel display. Press the button again and
the compressor will turn back on.
The A/C OFF feature is not available in the
defrost mode.
AUTO (Automatic): The AUTO button will turn on the
system and automatically adjust the fan speed, air
delivery mode and temperature to your previously
programmed settings.When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor ducts, the instrument panel or windshield
outlets. The fan speed will vary as the system maintains
the selected temperature setting.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP knob to adjust the temperature if
necessary. If you choose 60
F (16
C), the system will
remain at that maximum cooling setting and will not
regulate fan speed. If you choose 90
F (32
C), the system
will remain at that maximum heating setting and will not
regulate fan speed. Choosing either maximum setting will
not cause the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor cycles on and off when needed to cool the
air. In cold weather, when the system senses the need for
heat, the airflow will be directed out the floor ducts. As
the interior temperature approaches a desired setting, the
fan speed will decrease. To maintain interior comfort,
the airflow may move to the instrument panel air outlets
and floor ducts. On bright sunny days in cold weather,
the airflow may come out of the instrument panel outlets
to maintain comfort and prevent stuffiness.

3-6 Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best. Your A/C setting
may be adjusted automatically or manually. It may also
be set separately on the passenger's side from the
driver's side. See ªClimate Control Panelº earlier in this
section for more information.
Heating
Adjust the interior temperature to a comfortable level.
If the fan speed needs adjusting, press the up or down
arrow on the fan switch. Adjusting the fan speed will
cancel the cold air delay.
Outside air will be brought in and sent through the floor
ducts and the instrument panel outlets. The heater works
best if you keep your windows closed while using it. In
automatic operation, your fan will not run at high speed
to minimize warm
-up time.
Defogging and Defrosting
Use FRONT (defrost) on cool and humid days to keep
the windshield and side windows clear. This setting will
remove fog or ice from the windshield quickly in
extremely humid or cold conditions. If you desire to
have more air on your feet, turn the control to the defog
mode. You may do this by pressing the right or left
arrow on the MODE button.
Press the up or down arrow on the fan switch to control
the fan speed. You may also adjust the temperature by
turning a TEMP knob.
Recirculation and the A/C OFF feature are not available
in the defrost mode.

3-10 HVAC Steering Wheel Controls
(If Equipped)
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº in
the Index.
~TEMP !(Temperature): Press the up arrow on
the control to increase the temperature and the down
arrow to decrease temperature.
!~
(Fan): Press the up arrow on the control to increase
the fan speed and the down arrow to decrease fan speed.
Climate Control Personalization
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings. These settings
include the set temperatures for the driver and front
passenger, the air conditioning, the mode and the
fan speed. (This feature does not recall recirculation
or defrost).
Each driver (1 or 2) has a corresponding number located
on the back of the remote keyless entry transmitter.
Settings recalled by the system are determined by which
transmitter is used to unlock the vehicle. After the
button with the unlock symbol is pressed, the settings
are automatically recalled.
The settings can also be recalled when the key is placed
in the ignition. If the settings are recalled this way, the
system will recall the settings of the last driver. If these
are not the correct settings, you must press the button
with the unlock symbol on remote keyless entry
transmitter that was used when you saved your settings.

3-11
The settings can be changed by briefly pressing the
corresponding memory button (1 or 2) located on the
driver's door panel.
Further programming for recalling climate control
personalization settings can be done using the DIC.
You can select or not select the following:

Automatic recall of the climate control settings when
the vehicle is unlocked with the remote keyless entry
transmitter, or

Automatic recall of the climate control settings when
a key is placed in the ignition.For programming information, see ªVehicle
Programming and Personalization Featuresº in
the Index.
Your vehicle is equipped with a dual
-zone electronic
climate control system. This system can automatically
adjust and control temperature, fan speed, air delivery
mode, air conditioning operation and air intake. You can
use the AUTO (automatic) setting or override the
automatic operation by manually altering the controls.
