Low Fuel Warning Light

United States
If your vehicle is low on fuel, this warning light near the
fuel gage will come on.
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, the bulb may need to be
replaced. See your dealer to have it fixed right away.
