Shift Up light is an indicator to change gears to a higher ratio (e.g. go to 4th from 3rd) to improve mpg. It is a result of SAAB efforts to maximize mpg for the EPA CAFE rating. Typically it shows at about 2000 rpm and too often puts you too low in engine rev's (so you push the accelerator and waste more gas).
