Subaru Forester: Warning and indicator / Low fuel warning light

The low fuel warning light illuminates when
the tank is nearly empty, at approximately
2.5 US gal (9.5 liters, 2.1 Imp gal). It only
operates when the ignition switch is in the
“ON” position.
CAUTION
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 warning light illuminates if any door or
the rear gate is not fully closed. This
function is effective even if the ignition
switch is in the “LOCK”/“OFF” or “ACC”
position, or the key is removed from the
ignition switch...
