Low Fuel Warning
WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
This warning appears when the fuel level in the fuel tank is less than approximately 11.4 (3 US gal, 2.5 Imp gal). A variable resistor signal is supplied to the combination meter from the fuel level sensor unit and fuel pump (fuel level sensor) to determine the amount of fuel in the fuel tank.
