If your dashboard low fuel warning light comes on, you’ve better drive to a gas station—you’ve only got about a gallon of fuel left!
While it can be tempting to squeeze every drop of fuel out of your tank when the empty light comes on, you really shouldn’t let your gas tank sit lower than a quarter full, which is well before your low fuel light comes on.

What does the low fuel warning light mean?
The low fuel warning light has one purpose: to tell drivers that their fuel tanks are running low. If the yellow fuel pump symbol turns on, you need to drive to a gas station and fill up your fuel tank.
Your car’s driveability isn’t affected, and you can still drive safely. Just don’t plan on going for too long—you don’t want to find yourself out of fuel and stranded.
Aside from the risk of running entirely out of gas, you shouldn’t make a habit of driving with the low fuel warning light on. Your fuel pump needs fuel to act as a lubricant and coolant. When you run low (below a quarter tank), the fuel pump is no longer submerged, and you risk wearing it out faster.
Refilling your fuel tank before it dips below the last quarter, will help extend the life of your fuel pump.
