change time CHEVROLET CORVETTE 2004 5.G User Guide

Here are five things that some owners ask about. All
these things are normal and do not indicate that
anything is wrong with the fuel gage.
•At the gas station, the gas pump shuts off before
the gage reads F (full).
•It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank’s
capacity to fit it.
•The gage pointer may move while cornering,
braking or speeding up.
•The gage may not indicate E (empty) when the
ignition is turned off.
•The gage reading may change slightly within the
first several minutes after starting the vehicle.You can use the Driver Information Center (DIC) to
display more detailed fuel information. Each time you
press FUEL, one of the following will appear in the
Driver Information Center (DIC).
•AVERAGE:The fuel economy calculated for the
current tank of fuel, or since you last reset the
display.
•INST (Instant):The fuel economy calculated for
your current driving conditions.
•RANGE:The distance you can drive before
refueling.
You should reset the fuel information display every time
you refuel. To reset the display, press FUEL until
AVERAGE appears. Then, press RESET on the Driver
Information Center (DIC).

The average fuel economy is viewed as a long-term
approximation of your overall driving conditions. If you
press RESET in this mode while you’re driving, the
system will begin figuring fuel economy from that point
in time.
Press FUEL again to display instantaneous fuel
economy, such as:
•INST. 20.1 MPG or
•INST. 5.3 L/100 km
Press FUEL again to display the range, such as:
•RANGE 20 MI or
•RANGE 32 km
The range calculates the remaining distance you can
drive without refueling. It’s based on fuel economy and
the fuel remaining in the tank.
If the range is lower than 30 miles (48 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.
Resetting the fuel range causes the fuel economy
data to be updated immediately. Press RESET to reset
the fuel range.
2 GAGES
The GAGES button allows you to scroll through the
functions listed below when you press it.

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 OIL SOON.
When the oil life is down to zero, you will receive the
message CHANGE OIL NOW.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed. It
can’t be reset accurately until the next oil change.
