Fuel Gauge; Driver Efficiency Gauge - Buick 2013 Regal Owner's Manual

5-12 Instruments and Controls

Fuel Gauge

When the ignition is on, the fuel
gauge shows about how much fuel
is left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
When the vehicle's fuel level
becomes low, a message appears
in the Driver Information Center
(DIC) and a single chime sounds.
See
for more information.
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
At the service station, the
fuel pump shuts off before the
gauge reads full.
It takes a little more or less fuel
to fill up than the 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 takes a few seconds
to stabilize after the ignition is
turned on, and will go back to
empty when the ignition is
turned off.

Driver Efficiency Gauge

For eAssist vehicles, this gauge
assists in driving efficiently and
may vary based on driver input.
To maximize efficiency, keep the
gauge pointed in the solid green
zone in the center of the gauge.
The gauge moves to the left when
braking and to the right when
accelerating. When either is done
aggressively, the vehicle is being
driven less efficiently and the gauge
will move further from the center.
