Fuel Gage
Your fuel gage tells you
about how much fuel you
have left.
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 5-97.
Boost Gage
If your vehicle is equipped with this gage, it 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.
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 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.
