What it means

Symptoms3
- The light comes on as the fuel gauge nears empty.
- A chime or remaining range message on some cars.
- Engine stumbling in corners or on hills when fuel is very low.
Possible causes3
- Fuel has dropped to the reserve level.
- A faulty fuel level sender giving a false reading.
- A fuel leak from the tank or lines.
How to diagnose and fix4
- Head to the nearest fuel station and do not delay refuelling.
- Drive smoothly and avoid hard acceleration to save fuel.
- If you smell strong fuel or see a leak, switch off the engine and stay away from any flame.
- If the light is on with a full tank, have the level sender checked at a workshop.
