Driver Efficiency Gauge - Chevrolet Volt 2017 Owner's Manual

106 Instruments and Controls
Here are some things that 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 takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.

Driver Efficiency Gauge

This gauge appears on the left side
of the display in the Classic
Enhanced configuration.
This gauge is a guide to driving in
an efficient manner by keeping the
ball green and in the center of the
gauge.
See Driving for Better Energy
Efficiency 0 26.
accel : If the ball turns yellow and
travels above the center of the
gauge, acceleration is too
aggressive to optimize efficiency.
brake : If the ball turns yellow and
travels below the center of the
gauge, braking is too aggressive to
optimize efficiency.
In the Modern display
configurations, the light ring in the
center of the display acts as an
efficiency gauge. It is green when
driving efficiently and turns yellow
when acceleration or braking is too
aggressive.
