It will warn you that way if the car is parked uphill and tipping a bit to the left, maybe the reading sensor is installed somewhat to the right of the oil tank! got that warning a few times whenever the car was parked that way. After driving for a bit and being in somehow levelled terrain, shutdown for a minute or so! It will read nominal again and no warning displays!

Heard or read anywhere that it's most accurate if you do an oil level reading after the engine has been running and let it cool off for about an hour or so. Warm/cold fluid phisic dynamics i guess. Not pretty sure, but i think i got that advice from my 159's owners manual!
