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...
Other information:
This position is for parking the vehicle and
starting the engine. In this position, the
transmission is mechanically locked to
prevent the vehicle from rolling freely.
When you park the vehicle, first apply the
parking brake firmly, then shift into the “P”
position...
Remove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft brush then vacuum it.
Wipe the fabric surface with a tightly wrung
cloth and dry the seat fabric thoroughly...
