Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition is
in ON.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound.Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and do
not indicate that anything is wrong with the fuel gage:

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

The gage may change when you turn, stop quickly or
accelerate quickly.

It takes a little more or less fuel to fill the tank than
the gage indicated. For example, the gage may have
indicated that the tank was half full, but it actually
took a little more or less than half the tank's capacity
to fill the tank.
