Low Fuel Warning Light - GMC Sierra 2010 Owner's Manual

When the fuel tank is low the FUEL LEVEL LOW
message appears. See DIC Warnings and Messages
on page 4 65 for more information.
Here are some situations owners can experience with
the 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 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 fuel tank's
capacity to fill it.
The gage goes back to empty when the ignition is
turned off.
For a diesel engine, see Fuel Gage in the Diesel
Engine Supplement.

Low Fuel Warning Light

This light and a chime comes on when the fuel tank is
low on fuel. The Driver Information Center also displays
a FUEL LEVEL LOW message. See DIC Warnings
and Messages on page 4 65 for more information.
When fuel is added this light and message should go
off. If it does not, have the vehicle serviced by your
dealer/retailer.
This light, under the fuel
gage, comes on briefly
while the engine is being
started.
