GMC 2003 DURAMAX, Owner'S Manual

Page: 17 / 88

Listed are four situations you may experience with your
fuel gage:
•
At the gas station, the fuel pump shuts off before
the gage reads F (Full).
•
It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the tank’s
capacity to fill the tank.
•
The gage moves a little when you turn a corner or
speed up.
•
The gage doesn’t go back to E (Empty) when you
turn off the ignition.
None of these indicate a problem with the fuel gage.
For information on how to fill your fuel tank, see Filling
Your Tank on page 5-12.
For your fuel tank capacity, see “Fuel, Tank Capacity” in
the owner’s manual index.
Your vehicle also has a fuel cooler. To clean,
powerwash the bottom of the vehicle.
Driver Information Center (DIC)
The Driver Information Center (DIC) is located on the
instrument panel cluster above the steering wheel. The
DIC comes on when the ignition is on. After a short
delay the DIC will display the current driver and
the information that was last displayed before the engine
was last turned off.
If a problem is detected, a warning message will appear
on the display. Pressing the select button on the DIC
steering wheel buttons, or the trip odometer reset stem
for vehicles without DIC steering wheel buttons, will
acknowledge any current warning or service messages.
Two messages that your DURAMAX™ diesel may
show are:
ELEVATED IDLE DISABLED
On diesel engines, this message will appear when the
elevated idle/exhaust restrictor feature has been
turned off. For more information on the elevated
idle/exhaust restrictor feature, see Starting Your Diesel
Engine on page 2-2.
