How much fuel is left on when the low indicator comes with a 2004 trailblazer fuel?

The low fuel indicator light on a 2004 Chevrolet Trailblazer typically illuminates when approximately 1 to 2 gallons of fuel remain in the tank. However, this is just an estimate, and the exact amount can vary slightly depending on driving conditions and the vehicle's individual fuel system. It's best not to wait until the light comes on to refuel, as running the tank very low can damage the fuel pump.
