Fuel Gage
The fuel gage, when the ignition is on, tells you about
how much fuel you have left in your tank.
The gage will first indicate empty before you are out of
fuel, and you should get more fuel as soon as
possible.
When the fuel tank is low, the FUEL LEVEL LOW
message will appear. See DIC Warnings and Messages
on page 3-56.
Here are some situations you may experience with your
fuel gage. None of these indicate a problem with the
fuel gage.
•
At the gas station, the fuel pump shuts off before
the gage reads full.
•
It takes a little more or less fuel to fill up than the
fuel 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.
•
The gage goes back to empty when you turn off the
ignition.
Low Fuel Warning Light
This light, under the fuel
gage, will come on briefly
when you are starting
the engine.
