tC Specs on Fuel Reserve?

Just picked up my 5-speed Flint Mica tC last week...this car is so smooth! I looked though the owner's guide yesterday and noticed they don't specifiy how much fuel is left when the "low fuel" light comes on .... anybody know? Thanks!

Usually, it's 2-4 gallons when the light comes on.

2 gallons, 40-60 miles
