replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred or out of focus.
Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver Information
Center (DIC). The DIC will display information about
how your vehicle is functioning, as well as warning
messages if a system problem is detected. This feature also
allows two different drivers to store and recall their own
personal choice settings. See ªDIC Personal Choice
Programmingº later in this section.
DIC Displays and Controls
There are two lines in the DIC display. The DIC displays
the driver number identified when entering the vehicle.
You can have your dealer program your name to appear on
this display line. See your dealer for more information.
When you turn the ignition on, the DIC will display your
DRIVER NUMBER. The system will then perform a status
check and display any messages if a problem is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.
If a problem is detected, a diagnostic message will
appear in the display. The following pages will show the
messages you may see on the DIC display.
The message center is continuously updated with the
vehicle's performance status.

3-4 Dual Automatic Comfortemp
Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
Comfortemp Climate Control system, the following
information tells you how it works.You will hear a beep each time a button is pushed and a
light on the button will indicate which function is active.
The lights are on all buttons except TEMP, FAN and
AIR FLOW. The display will show fan speed, comfort
level setting and airflow direction for a few seconds
whenever AUTO is selected, and then it will display the
outside temperature. The outside temperature reading is
most accurate when the vehicle is moving. During stops,
the display shows the previous temperature for best
accuracy and system control.
If the display is flashing after the climate control system
is started, there is a problem with the system and you
should see your dealer for service.
Sun and temperature sensors automatically adjust the
air temperature, the airflow direction and the fan speed
to maintain your comfort setting. The system may
supply cooler air to the side of the vehicle toward the
sun. Be careful not to put anything over the sensor on
top of the dash.

Manual Operation
You may also manually adjust the air delivery or fan speed.
AIR FLOW: This button is used to change the direction
of the airflow. The airflow choices available are
WINDSHIELD
-FLOOR, MID, MID-FLOOR, and
FLOOR. If the system is set for AUTO, pressing the
AIR FLOW button will display and hold the current
airflow direction and the comfort setting. Press the AIR
FLOW up or down button again to change the direction
of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the windshield and the floor. If the AIR FLOW
down button is selected while in the FRONT defrost
mode, the system will direct the air toward the floor, and
the FRONT defrost mode will cancel. Notice the arrows
in the display.
OFF: If the passenger comfort control is turned on, it
can be turned off by pressing the OFF button once.
Pressing the OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed toward the
floor. The system will still try to keep the interior of the
vehicle at the previous chosen comfort setting. The
outside temperature will show on the display when the
system is OFF.The ventilation system always allows fresh air to flow
through your vehicle when the vehicle is moving even
with the system in the OFF mode.
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting VENT and the AUTO
button at the same time allows the system to control
automatically without the use of the RECIRC mode.
To turn off the VENT selection, push the VENT button
again. If you select VENT while in FRONT defrost, the
VENT light will flash three times to let you know this is
not allowed. This is to prevent fogging.
RECIRC: When RECIRC is selected, the system will
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. RECIRC and AUTO may be
selected at the same time. The system will remain in
RECIRC until the ignition is turned off, then the system
will return back to the previously selected mode.
Deselecting the RECIRC button will also turn off the
RECIRC function. RECIRC can be selected in all
manual airflow modes except FRONT defrost and
VENT. If you select RECIRC while in FRONT defrost,
the RECIRC light will flash three times to let you know
this is not allowed. This is to prevent fogging.

FRONT: This selection is used to defrost the windshield
by directing the airflow toward the windshield.
If FRONT is selected while in the AUTO mode, the fan
speed and the air temperature from the front defroster will
vary. If a manual fan speed setting is selected, the fan
speed will remain at that selection until another fan speed
selection is made or the AUTO mode is selected. To turn
off FRONT, press the AUTO or AIR FLOW button.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.
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.
If you have the electronic touch system, for quick
cool
-down on very hot days, use MAX with the
temperature and fan speed adjusted to COOL and
HIGH. If this setting is used for long periods of time, the
air in your vehicle may become too cold and dry.For normal cooling on hot days, use NORM and adjust the
temperature and fan speed for your comfort. If RECIRC is
selected while in the NORM air conditioning mode, the
system works like MAX and recirculates the air.
On sunny days, when the air is moderately warm or
cool, use BI
-LEV to deliver warm air to the floor and
cooler air to the middle instrument panel outlets. On
days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when RECIRC is selected. This is helpful when you are
trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic Comfortemp
system and it is set for AUTO, on very hot days, the
system will automatically enter the RECIRC mode and
the temperature door will be positioned at the full cold
position for maximum cooling. If the system is not in
the AUTO mode, RECIRC should be selected to provide
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.

3-8 Heating
If your vehicle has the electronic touch system, on
cold days, use HTR with the TEMPERATURE lever
toward WARM.
If your vehicle has the Dual Automatic Comfortemp
system, and on cold days, if the AUTO mode is selected,
the system will automatically direct the air toward the
floor 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. If
the outside temperature is cold, the fan will be delayed
to avoid blowing cold air. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn off the
AUTO mode and change the fan speed.
With each system, outside air will be brought in and sent
through the floor outlets. The heater works best if you
keep your windows closed while using it.
Defogging and Defrosting
If you have the electronic touch system, adjust
the TEMPERATURE lever toward WARM and the
FAN lever toward HIGH.
If you have the Dual Automatic Comfortemp system,
use the FRONT button to defog or defrost the
windshield. By choosing this button, the airflow will be
directed at the windshield. Adjust your comfort level by
pressing the TEMP up or down arrow. The fan speed
will be controlled by the system. You can change the fan
speed by pressing the top of the FAN button to increase
speed, and the bottom of the button to decrease speed.
To reduce the chance of fogging your windows in cold
weather, using the electronic touch system, select HTR
to supply air through the floor outlets. Then move the
FAN lever to HIGH for a few moments before driving
away. This will blow moist air from the intake outlets
toward the floor, not the windshield. If you have the
Dual Automatic Comfortemp system, the AUTO setting
will do this for you. Manual operation of the automatic
comfortemp system in the FLOOR mode will also
supply air through the floor outlets.
