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:
CAUTION
Do not turn the ignition switch to the
“START” position while the engine
is running.
NOTE
To turn the key from the “ACC” to
“LOCK” position, the select lever must
be in the “P” position and the key must
be pushed in and turned...
So that it can be used safely and comfortably,
the Auto Start Stop system is
designed to constantly monitor the vehicle
conditions as well as the environment
inside and outside the vehicle in addition
to driver operations, and to provide various
warnings to the driver via the warning light
and/or indicator light illuminating or flashing
and a buzzer sounding...
