DIC Operation and Displays
The DIC comes on when the ignition is on. After a short
delay the DIC will display the current driver and the
information that was last displayed before the engine
was turned off.
If a problem is detected, a warning message will
appear on the display. Pressing the select button will
acknowledge any current warning or service messages.
The DIC has different modes which can be accessed by
pressing the four buttons on the DIC. These buttons are

Trip Information Button
Use the trip information button to scroll through the
odometer, TRIP A, TRIP B and TIMER.

appears on the display. This shows the total distance the
vehicle has been driven in either miles or kilometers.
Pressing the reset stem located on the instrument cluster
with the vehicle off will also display the odometer.Trip A and Trip B
Press the trip information button until TRIP A or TRIP B
is displayed. This shows the current distance traveled
since the last reset for each trip odometer in either miles
or kilometers. Both odometers can be used at the
same time.
Each trip odometer can be reset to zero separately by
pressing select while the desired trip odometer is
displayed. You can also reset the trip odometers with the
reset stem on the cluster. If you press and hold the reset
stem for four seconds, the display will show the distance
traveled since the last ignition cycle.

The DIC can be used as a stopwatch. Press the select
button while TIMER is displayed to start the timer. The
display will show the amount of time that has passed
since the timer was last reset (not including time the

shown on the DIC. The timer will record up to 99 hours,
59 minutes and 59 seconds (99:59:59) after which the
display will roll back to zero.

Comfort Controls
This section tells you how to use the comfort controls.
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.
Comfort Controls Personalization
(If Equipped)
If your vehicle is equipped with the automatic comfort
control system and memory seats and mirrors, you
can store and recall the climate control settings for
temperature, air delivery mode and fan speed for
two different drivers. The personal choice settings
recalled are determined by the transmitter used to enter
the vehicle. After the button with the unlock symbol on
a remote keyless entry transmitter is pressed, the climate
control will adjust to the last settings of the identified
driver. The settings can also be changed by pressing
one of the memory buttons (1 or 2) located on the
driver's door. When adjustments are made, the new
settings are automatically saved for that driver.
Manual Dual Zone Comfort Controls
With this system, you can select different comfort
control settings for the driver and passengers.
Fan Knob
The knob on the left side of the climate control panel
regulates the fan speed. You can choose from
five different fan speeds or turn the fan off.
Driver's Side Temperature Lever
The lever on the left side of the climate control panel is
used to adjust the air temperature on the driver's side,
independent of the temperature set by the passenger.
Slide the lever upward to raise the temperature. Slide the
lever downward to lower the temperature.

3-3
Passenger's Side Temperature Lever
The lever on the right side of the climate control panel
is used to adjust the air temperature on the passenger's
side, independent of the temperature set by the driver.
Slide the lever upward to raise the temperature. Slide
the lever downward to lower the temperature.
This lever also adjusts the temperature to the rear
seat outlets.
Mode Knob
The knob on the right side of the control panel has
several settings to control the direction of airflow:
(Panel): Selecting panel mode will deliver air to
the instrument panel outlets.
(Bi-Level): Selecting bi-level mode will deliver
warmer air to the floor and cooler air to the instrument
panel outlets.
(Floor): Selecting floor mode will deliver air to
the floor outlets and some air to the defroster and side
window vents.
(Defog): Selecting defog will deliver air to the
floor, windshield outlets and side window vents.
(Defrost): Selecting this setting directs most of the
air through the defroster and side window vents. Some
of the air also goes to the floor ducts.
Mode Buttons
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle and for maximum air conditioning performance
in hot weather. Recirculation cannot be used in floor,
blend or defrost modes. An indicator on the button will
light up, flash three times and turn off when
recirculation is selected in these modes.
While in the recirculation mode the windows may fog
when the weather is cold and damp. To clear the fog,
select either the blend or defrost mode and increase the
fan speed.
(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
air conditioning compressor is engaged.

3-10 Rear Comfort Controls
Your vehicle has one of the following rear comfort
control systems. With either system, the rear comfort
controls will be disabled when the front comfort control
system is in defrost. This occurs to provide maximum
airflow to clear the windshield.
The temperature of the air coming through the rear
outlets is determined by the front passenger's
temperature setting. Press the PWR button to turn the
rear comfort controls on and off. Use the mode knob to
change the direction of airflow (upper, bi
-level or floor)
to the rear seat area.
If your vehicle has the rear seat audio system the lower
buttons are used to adjust the rear seat comfort controls.
The temperature of the air coming through the rear
outlets is determined by the front passenger's
temperature setting. The button with the up and down
arrows on it regulates the fan speed. The mode button
can be used to change the direction of airflow (upper,
bi
-level or floor) to the rear seat area. To turn the rear
comfort controls off, press the lower PWR button.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.

In cool damp weather, minimize your use of
recirculation to reduce the chance of fogging
your windows.

When you enter a vehicle with the standard system
in cold weather, select floor mode to supply air
through the floor outlets. Then turn the fan on high
for a few moments before driving away. This will
blow moist air from the intake outlets toward the
floor, not the windshield. It reduces the chance of
fogging your windows. If you have the electronic
system, the AUTO setting will do this for you.
Manual operation of the electronic system in the
floor mode will also supply air through the
floor outlets.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.Comfort Control Steering Wheel Controls
(If Equipped)
If your vehicle has this
feature, you can control
certain comfort control
functions using the buttons
on your steering wheel.
(Fan): Press the up arrow to increase the fan speed
and the down arrow to decrease the fan speed.
(Temperature): Press the up arrow to increase the
temperature of the air flowing through the system and
the down arrow to decrease the temperature of the air
flowing through the system.

few seconds. The radio will scan through each of the
stations stored on your pushbuttons, except those
stations with weak reception. Press one of the arrows or
one of the pushbuttons again to stop scanning. SCAN
