Black plate (13,1) Chevrolet Corvette Owner Manual - 2012
Instruments and Controls 5-13
Here are five things that some
owners ask about. All these things
are normal and do not indicate that
anything is wrong with the fuel
gauge.
. At the service station, the gas
pump shuts off before the gauge
reads the full.
. It takes a little more or less
fuel to fill up than the gauge
indicated. For example, the
gauge may have indicated half
full, but it took a little more or
less than half of the tank's
capacity to fill the tank.
. The gauge pointer may move
while cornering, braking or
speeding up.
. The gauge may not indicate the
tank is empty when the ignition
is turned off.
. The gauge reading may change
slightly within the first several
minutes after starting the
vehicle.

Boost Gauge (ZR1)
Metric
English
This gauge indicates vacuum during
light to moderate throttle and boost
under heavier throttle.
It displays the air pressure level in
the intake manifold before it enters
the engine's combustion chamber.
The gauge is automatically centered
at zero every time the engine is
started. Actual vacuum or boost is
displayed from this zero point.
Changes in ambient pressure,
such as driving in mountains and
changing weather, will slightly
change the zero reading.
