Temperature Buttons
To adjust the comfort level you want maintained inside
the vehicle, use the red and blue buttons located below
the digital display. If you want a warmer comfort level,
push the red button. If you want a cooler comfort level,
push the blue button. Your selected comfort setting will
be displayed on the digital screen for five seconds, then
the outside temperature will be displayed.
Mode Control
Turn the AUTO
-PUSH knob to deliver air through the
floor, upper or windshield outlets. The system will stay
in the selected mode until the AUTO
-PUSH knob
is pressed.
AUTO FAN Knob
This knob controls the fan speed in either an automatic
mode or a manual mode.

Pressing the AUTO FAN knob puts the fan control in
the automatic mode. The AUTO FAN light will
appear below the knob. The fan speed indicators will
not be illuminated when the system is in the
automatic fan control mode.
Turning the AUTO FAN knob selects a manual fan
speed. Turn this knob clockwise to raise the fan
speed. Turn this knob counterclockwise to lower the
fan speed. Turning the AUTO FAN knob overrides
the automatic fan control mode. The fan speed
indicators will be illuminated while in the manual
fan control mode.
Automatic Operation
Press the AUTO
-PUSH knob when you want the system
to automatically adjust the interior temperature to your
preference. When the system is set for automatic
operation, air will come from the floor, the upper outlets
or the windshield outlets depending on the temperature
inside the vehicle, the outside temperature and the sun
load. Fan speed will vary as the system reaches and
maintains the comfort setting you have selected.
To find your comfort setting, start with the system in
automatic mode by pressing the AUTO
-PUSH knob.
Adjust the comfort setting by using the red and blue
buttons located below the digital display until you reach
a setting of 75F (24C) on the display. Give the vehicle
about 20 minutes to stabilize and then readjust the
comfort setting if necessary. The display will show the
comfort setting for five seconds and then it will show
the outside temperature.

3-4
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Turning the AUTO FAN knob will
override this delay by turning off the automatic fan
mode and changing the fan speed.
Your automatic electronic climate control system has
two sun sensors located on the top of the instrument
panel that detect direct sunlight. To keep you and your
passengers comfortable, the system may supply cooler
air to the side toward the sun. Be careful not to put
anything over these sun sensors. The automatic
electronic climate control system may not operate
correctly if these sensors are covered.To change the automatic electronic climate control
display from an English display to a metric display, push
the OFF button located in the Driver Information Center
(DIC) for two seconds. The display in the DIC will also
change from an English to a metric display. To return to
an English display, repeat the above procedure.
Manual Operation
You may override the automatic airflow distribution by
turning the AUTO
-PUSH knob. After you turn this
knob, the comfort setting will be displayed for five
seconds, then the outside temperature will be displayed.
The fan control will remain in the automatic control
mode unless you turn the AUTO FAN knob to select a
manual fan speed.
UPPER: This setting directs airflow through the
upper air outlets located in the instrument panel and
door panels.
BI-LEVEL: This setting directs the airflow
through both the upper air outlets and the lower floor
outlets. There is also a small amount of air directed to
the front defroster and the side window defrosters.
HEAT: This setting directs most of the airflow to
the lower floor outlets with some airflow directed to the
side window defrosters. There is also a small amount of
airflow directed to the front defroster.

3-5
DEFOG: This setting directs the majority of the
airflow to the lower floor outlets and the front defroster.
A small amount of airflow is directed to the side
window defroster outlets. This mode can be useful to
remove the moisture from the inside of the windshield
when the outside temperature is cold or the humidity
is high.
DEF (Defrost): This setting directs the majority
of the airflow to the windshield with some airflow to
the side window defrosters and lower floor outlets.
To increase the fan speed, turn the AUTO FAN
knob clockwise.
RECIRC ON: Press this button to limit the amount of
outside air entering your vehicle. This is helpful when
you are trying to cool the interior of the vehicle quickly
or limit the amount of outside air entering your vehicle
for some other reason. The RECIRC ON button and the
AUTO
-PUSH knob may be selected at the same time.
The system will remain in RECIRC ON until the
ignition is turned off, then the system will return back to
the previously selected mode. RECIRC ON may be
selected in all manual airflow modes except
front defrost.Operating the RECIRC ON mode in cold temperatures
or under high humidity conditions may cause moisture
to form on the inside of the windshield. If this condition
occurs, deselect the RECIRC ON button.
A/C ON: Press this button to turn the air conditioning
on and off. If the system is operating in the automatic
mode, the A/C ON indicator light will automatically
illuminate. In the auto mode, the A/C compressor will
only operate when the system determines it is needed.
OFF: Turn the AUTO
-PUSH knob to OFF. Turning the
system off will cause the fan to turn off and the airflow
to be directed out the lower floor outlets. The system
will still try to keep the interior of the vehicle at the
previously chosen comfort setting. The outside
temperature will show in the display when the system is
set to OFF.

3-6 Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all modes
unless the A/C ON button is in the off position (the
indicator light will not be illuminated). However, the air
conditioning compressor will not operate when the
outside temperature is below 42
F (7
C). When the air
conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level. If the
system is in the automatic mode (AUTO
-PUSH knob
indicator light is on), during very hot days the system
will automatically go to the RECIRC ON mode and the
temperature door will be positioned at the full cold
position for maximum cooling. You can choose the
extreme comfort setting of 60
F (16
C), but the
system will not cool any faster by choosing the extreme
comfort setting.
Heating
In cold weather, if the automatic mode is selected
(AUTO
-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of 90
F (32
C), but the system will not
warm up any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature of the engine coolant increases. Turning the
AUTO FAN knob will override this delay by turning off
the automatic fan control mode and changing the
fan speed.

3-7 Defogging and Defrosting
On cool, humid days, use the defog setting to keep the
windows clear while also providing heat through the
lower outlets. Turn the AUTO
-PUSH knob clockwise to
DEF to quickly remove fog or ice from the windshield.
Rear Window Defogger
R. DEFOG: Press this
button to warm the defogger
grid on the rear window. An
indicator light below the
button will glow while the
rear window defogger
is operating.
At speeds above 30 mph (48 km/h), the rear defogger
will stay on until you press the R. DEFOG button again.
At speeds below 30 mph (48 km/h), the rear window
defogger will turn off automatically after about
10 minutes of use. If you press it again, the defogger
will operate for about five minutes only. You can also
turn the defogger off by turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
When you operate the rear window defogger,
the outside rearview mirrors are also heated to help
remove ice and fog.

NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Passenger Temperature Control
With this feature, the right
front seat passenger can
control the comfort setting
for their own zone. To use
this feature, adjust the
control on the passenger's
side armrest to the desired
comfort level.
The passenger's temperature control on the passenger's
armrest will illuminate only if the headlamps or parking
lamps are on.
Ventilation System
Your vehicle's flow-through ventilation system always
allows outside air to flow through your vehicle when it
is moving, even when the system is off.
The direction of the air can be controlled by adjusting or
closing the outlets in the instrument panel. Turn the
control between the front outlets upward to open the
outlets and downward to close the outlets. Adjust the
direction of airflow from side to side with the controls in
each outlet.

Turn the control between the rear outlets up to direct air
through the upper outlets. Turn the control down to
direct air through the lower outlets. Adjust the direction
of airflow from side to side with the controls in
each outlet.Ventilation Tips

Keep the hood and front air inlet area between the
base of the windshield and the hood free of ice,
snow, or any other obstruction (such as leaves). The
defroster and heater will work far better, reducing
the chance of fogging the inside of your windows if
this area is clear.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
Steering Wheel Controls for
Climate Control
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls also operate
some audio controls. See
ªAudio Steering Wheel
Controlsº later in
this section.
