2007 CHEVROLET COBALT service

Here are four things that some 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 ll 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 ll the tank.
The gage moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
For your fuel tank capacity, seeCapacities and
Specications on page 390.
Boost Gage
If equipped, this gage is located near the driver’s
side of the instrument panel cluster.
This gage indicates vacuum during light to
moderate throttle and boost under heavier throttle.
This gage displays the air pressure level in the
intake manifold before it enters the engine’s
combustion chamber.
This gage is automatically centered at zero every
time the ignition is turned to RUN. 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.
