Here are four things that some
owners ask about. None of these
show a problem with your fuel gage:
.
At the service station, the fuel
pump shuts off before the gage
reads full.
.
It takes a little more or less fuel
to fill up than the 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 moves a little while
turning a corner or speeding up.
.
The gage takes a few seconds
to stabilize after the ignition is
turned on, and will go back to
empty when the ignition is
turned off.
Boost Gage
United States
Canada
For the CTS-V, this gage is located
in the instrument panel cluster.
This gage indicates positive
manifold pressure which is the
induction air pressure level in the
intake manifold before it enters the
combustion chamber. This gage
reads zero under light throttle before
boost is generated.
This gage automatically resets to
zero every time the engine is
started.
