ignition CHEVROLET CORVETTE 2008 6.G Service Manual

Here are ve 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 the full symbol.
It takes more (or less) fuel to ll 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 t it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty when
the ignition is turned off.
The gage reading may change slightly within the
rst several minutes after starting the vehicle.
SeeDIC Operation and Displays on page 3-52for more
information.
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.
If your vehicle has the Head-Up Display (HUD) and you
use the Manual Paddle Shift feature, the gear will
display in the HUD, except if your vehicle has the
Navigation system and the HUD is displaying
turn-by-turn guidance information. If the HUD is

Shift” underAutomatic Transmission Operation on
page 2-26and “Head-Up Display (HUD)” in the index of
the Navigation system manual for more information.
