I had this light come on in my 207 Coupe a few years back. It happened after I had performed and oil/filter change. During that oil change, I attempted to pour in 8.5 quarts of oil since the Owners & Service Manuals said the proper oil fill was 8 liters (8.4535 quarts).All seemed good; oil level on dipstick was all the way to the full mark, maybe slightly above. Anyway, a few weeks after, I was driving in the 'twisties' of the NC/TN mountains with other Crossfire Owners and the 'HIGH LEVEL' oil warning light kept coming on telling me there was too much oil in the system. The forces experienced during all those 'twisties' sloshed the oil around enough to trigger that warning. After I got home, I sucked out about a 1/2 quart and everything was good after. From that point on, every time I do an oil change, I only add 8 quarts of Mobil 1 (which is what quite a few of us do that live in CONUS). Never had any more issues with the 'low level' oil light coming on and if I check the dipstick after an oil change, oil level is right at or ever so slightly below the FULL mark.

Here's the page from the 2007 Owners Manual that covers the Oil Level Indicator Light:
