2007 GMC SIERRA CLASSIC engine

Here are some situations you may experience with
your fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll 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 ll the tank.
The gage goes back to empty when you turn
off the ignition.
If you have a diesel engine, see “Fuel Gage” in
the Diesel Engine Supplement.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.
SeeFuel on page 470.
Driver Information Center (DIC)
The Driver Information Center (DIC) display is
located on the instrument panel cluster, below the
speedometer. If your vehicle has DIC buttons,
they are located on the steering wheel. The DIC
can display information such as the trip odometer,
fuel economy, customization features, and
warning/status messages.
If your vehicle does not have DIC steering wheel
buttons, you will not have all of the features
listed. Scroll through the odometer, trip odometer,
engine hours, and selected range if your vehicle

the shift lever is in the MANUAL MODE (M)
position, the DIC will display the current gear
range. The DIC will also display the gear range as
it is shifted up or down. For example, if the gear
range is currently set to 6, the DIC will display
(6)54321. When thegear range is shifted down
one time, the DIC will display 6 (5)4321. See
