Back in the late 80's a coworker got a fancy new car that talked to him. One morning on the way to work his car sputtered and died in the middle of a long bridge. As his car coasted to a stop, the voice came on telling him "fuel level low." I am glad that Toyota is conservative and has a reserve.Perhaps Toyota should link the low fuel light to the fuel injection pressure sensor. Low fuel pressure = empty tank. That way drivers will know when tank is actually empty. Makes sense, doesn't it?
