Low Fuel Warning Light
This light, under the fuel gauge, comes on briefly while the engine is being started.
This light and a chime, if the vehicle is equipped with a radio, comes on when the fuel tank is low on fuel.
The Driver Information Center also displays a FUEL LEVEL LOW message. See Fuel System Messages on page 5‑46 for more information. When fuel is added this light and message should go off. If it does not, have the vehicle serviced by your dealer.
