Fuel Gage

When the ignition is on, your fuel gage lets you
know about how much fuel you have left. When the
gage first shows empty, you'll still have a little fuel
left, but you should get more fuel soon.
If your vehicle has dual fuel tanks, the reading on
the gage is the total fuel left in both tanks.
Your fuel gage is
located on the right side
of your instrument
panel cluster.
