or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. It is also used
to display driver personalization features and
warning/status messages. The DIC display is located on
the instrument panel cluster below the speedometer
and tachometer, directly above the steering column. The
DIC buttons are located on the instrument panel, to
the right of the instrument panel cluster.
The DIC comes on when the ignition is turned on. After
displaying CORVETTE BY CHEVROLET, 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 DIC display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.
DIC Controls and Displays
The Driver Information Center (DIC) has different modes
which can be accessed by pressing the following
buttons located on the instrument panel, to the right of
the instrument panel cluster.
.4(Fuel):Press this button to display fuel information
such as fuel economy and range.
3-49

Fuel Range:The range calculates the remaining
distance you can drive without refueling. It is based on
fuel economy and the fuel remaining in the tank.
Press the fuel button again to display the range,
such as:
RANGE 30 MI or
RANGE 48 km
If the LOW FUEL warning is displayed or if RANGE
is less than 40 miles (64 km), the display will read
RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your
driving conditions change, this data is gradually updated
automatically.
If the vehicle has been idling for a long time, the range
displayed on the DIC could be abnormally low. The
vehicle must be driven 5–10 miles (8–16 km) to get an
accurate reading.
GAGES Button
The gages button displays oil pressure, oil temperature,
coolant temperature, transmission uid temperature
for automatic transmission vehicles only, battery voltage,
and tire pressure information.
Oil Pressure:This display shows the oil pressure.
Press the gages button to display the oil pressure,
such as:
OIL PRESSURE 40 PSI or
OIL PRESSURE 276 kPa
Oil Temperature:This display shows the oil
temperature.
Press the gages button again to display the oil
temperature, such as:
OIL TEMPERATURE 234°F or
OIL TEMPERATURE 112°C
If the oil temperature is low, the display will show OIL
TEMPERATURE LOW. If the oil temperature is high, the
display will show OIL TEMPERATURE HIGH.
3-51

Average Speed:Press the TRIP button until the
average speed is displayed, such as:
AVERAGE SPEED 62 MPH or
AVERAGE SPEED 100 km/h
Press and hold the RESET button to reset to 0.0 mph.
Engine Oil Life:Press the TRIP button until the
engine oil life is displayed, such as OIL LIFE
REMAINING 89%.
This is an estimate of the engine oil’s remaining useful
life. It will show 100% when the system is reset after
an oil change. It will alert you to change your oil
on a schedule consistent with your driving conditions.
When the remaining oil life is low, the system will
alert you with the message CHANGE ENGINE OIL.
Remember, you must reset the engine oil life system
yourself after each oil change. It will not reset itself. To
reset the system, press and hold the RESET button
for three seconds. Also, be careful not to reset the
engine oil life system accidentally at any time other than
when the oil has just been changed. It cannot be
reset accurately until the next oil change.
