fuel tank capacity PONTIAC BONNEVILLE 2003 Owners Manual

On vehicles with a DIC, the CHECK GAGES LOW
FUEL message will be displayed when the fuel gage
reads
in the yellow band. See DIC Warnings and
Messages on page
3-60 for more information.
Here are some things that owners ask about. None of
these show a problem with your fuel gage:
At the service station, the gas 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.
Boost Gage
Vehicles equipped with the supercharged engine have
this boost gage that
indicates vacuum during
light to moderate
throttle and boost under
heavier throttle.
The gage displays the air pressure level going into the
engine’s combustion chamber.
The gage is automatically centered at zero every time
the ignition key is turned to
ON. 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.
