Amber light
Low Fuel Warning Light
The fuel level has reached the reserve.
Normal risk
Refuel soon. Running a tank completely dry can damage the fuel pump and, on diesels, need the system bled.
Short answer · How far can I drive when the low fuel light comes on?
It depends on the car: the reserve is often enough for several dozen kilometres, but this varies widely by model, driving style and how long the light has been on. Many cars show a remaining range. Refuel at the next opportunity rather than testing the limit.
What to do
- Plan a stopRefuel at the next station.
- Drive smoothlyGentle driving stretches the reserve.
- Do not run dryRunning out can damage the pump; diesels may need bleeding.
