Driver Information Center (DIC)
The DIC display is located on the instrument panel
cluster above the steering wheel. The DIC can display
information such as the trip odometer, fuel economy and
personalization features.
A (Trip Information):This button will display the
odometer, personal trip odometer, business trip
odometer, hourmeter, annual log and the timer.
B (Fuel Information):This button will display the
current range, average fuel economy, instant fuel
economy and engine oil life.C (Personalization):This button will change personal
options available on your vehicle.
D (Select):This button resets certain functions and
turns off or acknowledges messages on the DIC.
If your vehicle is not equipped with the DIC steering
wheel buttons you will not have all of the features listed
above, and you will turn off, or acknowledge DIC
messages by using the trip odometer reset stem located
on the instrument panel cluster.
DIC Operation and Displays
The DIC comes on when the ignition is on. After a short
delay the DIC will display the current driver (1 or 2)
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 any of the four buttons will
acknowledge (clear) most current warnings or service
messages. Some warnings that cannot be
acknowledged (cleared) are: ENGINE OVERHEATED,
OIL PRESSURE LOW, REDUCED ENGINE POWER,
TRANS HOT IDLE ENGINE. These warnings must
be dealt with immediately and therefore cannot
be cleared until the problem has been corrected.

button and the trip information button at the same
time. The DIC will begin scrolling through the languages
in their particular language. English will be in English,
French will be in French and so on. When you see
the language that you would like, release both buttons.
The DIC will then display the information in the
language you chose.
You can also scroll through the different languages by
pressing and holding the trip reset stem for four
seconds, as long as you are in the odometer mode.
Select Button
The select button is used to reset certain functions and
turn off or acknowledge messages on the DIC display.

this button will reset the trip odometers, turn off the
FUEL LEVEL LOW message, and toggle through
the languages you can select the DIC to display
information in.
DIC Warnings and Messages
Warning messages are displayed on the DIC to notify
the driver that the status of the vehicle has changed and
that some action may be needed by the driver to
correct the condition. If there is more than one message
that needs to be displayed they will appear one after
another. Some messages may not require immediate
action but you should press the select button to
acknowledge that you received the message and clear it
from the display. Some messages cannot be cleared
from the display because they are more urgent. These
messages require action before they can be removed
