Low fuel warning symbol

What this light means

The fuel level has fallen into the reserve. Most cars hold roughly enough for another 50 km at this point, but the figure varies a great deal between models, and the gauge is at its least accurate near empty.

Common causes

  • The tank is genuinely low
  • Steep slopes or hard cornering moving fuel away from the sender
  • A failing fuel level sender, if the light behaves oddly

What to do now

Refuel at the next reasonable opportunity rather than seeing how far it will go.

Running a tank to empty draws sediment from the bottom of it through the fuel system, and in a diesel it can let air into the fuel lines. Restarting a diesel that has run dry is often a workshop job, not a roadside one.

When to see a mechanic

If the light comes on when the tank is clearly not low, or never comes on at all — both point at the level sender.
