Boost Gauge (Performance Configuration Only) - Cadillac CTS Owner's Manual

Uplevel Balanced Configuration
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refuelled soon.
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
stabilise after the ignition is
turned on and goes back to empty
when the ignition is turned off.
