the computer only knows, level so if the level is wrong
its will just do the math (compare) and set the low fuel lamp.
i guess you lost the operators guide, it tells you when that happens get car serviced
if you have tools scan it.
Am I to guess, car drives perfectly and all other accessories on car are ok. as that is first, first;.
if yes, the the tank fuel sensor or wires to it are bad
but we scan it first after checking fuses.
no photo of your warning lamps. so no accurate answers ever.
your opr. guide page 145 covers this. (instruments)
page 157 error 22 , "circle/ bar key" is the IMMOBILIZER.
if that lamp glows the car will never start and drive (runs 2 seconds only as the guide told you)
you NEVER SAID that....??????DOES NOT DRIVE.
here i will read page 14 to you, with IMMO lamp glowing
"Afterwards,
if the bulb remains on, this indicates a malfunction in the
electronics. If the bulb begins to flash immediately after
the ignition switch is turned on, this indicates that an
invalid key is being used to start the vehicle. Both of
these conditions will result in the engine being shut
down after 2 seconds of running. Keep in mind that a key
which has not been programmed is also considered an
invalid key even if it is cut to fit the ignition for that
vehicle.
If the SKIS indicator light comes on during normal
vehicle operation (it has been running for longer than 10
seconds) a fault has been detected in the electronics and
the vehicle
should be serviced as soon as possible."
if you lost your book
here it is, last chance is this year,

check fuses.

then scan it.
