Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2012
Listed are four situations that may
occur with the fuel gauge, none of
these indicate a problem:
At the gas station, the fuel pump
shuts off before the gauge reads
F (full).
It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge 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 gauge moves a little while
turning a corner or speeding up.
The gauge does not go back to
E (empty) when the ignition is
turned off.

This gauge is to assist in driving
efficiently and may vary during
normal operation.
The vehicle is being driven the most
efficient when the gauge is kept in
the middle.
The gauge moves to the left when
braking and to the right when
accelerating. when either are done
aggressively, the efficiency is
decreased.
