Low Fuel Warning
Fuel is at reserve level — typically 30–50 miles of range remain.
What it means
The tank has reached the reserve threshold (commonly 1.5–2.5 gallons remaining). Habitually running on reserve can overheat the fuel pump, which relies on fuel for cooling, and can draw sediment from the bottom of the tank.
Can you keep driving?
Yes — directly to a gas station. Most cars have 30–50 miles after the light comes on, but this varies widely; check your owner's manual and don't push it.
What to do now
- 1
Refuel at the next convenient station.
- 2
Avoid making a habit of running on reserve to protect the fuel pump.
- 3
If the light stays on after a fill-up, the sender or cluster may need diagnosis.
Likely causes
- • Low fuel level
- • Faulty fuel-level sender (light on with a full tank)
Typical fix cost
$0 to refuel; $200–$600 for a fuel-level sender
