Low Fuel Warning Light - Chevrolet 2010 Avalanche Owner's Manual

The gage first indicates empty before the vehicle is out
of fuel, and the fuel tank should be filled soon.
When the fuel tank is low, the FUEL LEVEL LOW
message appears in the Driver Information Center
(DIC). See
for more information.
Here are some situations customers may 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 tank's
capacity to fill the tank.
The gage goes back to empty when the ignition is
turned off.
