Subaru Legacy: Low fuel warning light
The low fuel warning light illuminates when the fuel tank is nearly empty. It only operates when the ignition switch is in the “ON” position. When this light illuminates, fill the fuel tank immediately.
Promptly put fuel in the tank whenever the low fuel warning light illuminates. Engine misfires as a result of an empty tank could cause damage to the engine.
● The low fuel warning light illuminates when the remaining amount of fuel in the tank has reached approximately 2.6 US gal (10 liters, 2.2 Imp gal).
● The low fuel warning light does not turn off unless the tank is replenished up to a fuel quantity of approximately 4.0 US gal (15 liters, 3.3 Imp gal).
