When the gage reads in the colored band, a warning
chime will sound and the CHECK GAGES warning
light will come on. You still have a little fuel left, but
you need to get more fuel right away.
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” in the Index 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 (If Equipped)
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.
