Driver Information Center (Dic); Dic Operation And Displays - Chevrolet 2004 Tahoe Owner's Manual

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.
3-56
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.
