2-80 Fuel Gage
United States Canada
Your fuel gage tells you about how much fuel you have left
when the ignition is on. When the indicator nears empty, you
still have a little fuel left, but you should get more soon.
Here are four things that some owners ask about. All
these things are normal and do not indicate that anything
is wrong with the fuel gage:

At the gas station, the pump shuts off before the gage
reads full.

It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it took
more (or less) than half of the tank's capacity to fill it.
The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate empty when the ignition
is turned off.
Low Fuel Light
United States Canada
If your fuel is low, a circular light on your instrument
panel cluster will come on and stay on and a chime will
sound periodically until you add fuel.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working.
If it doesn't come on then, have it fixed.
