Hi Margie! Erin here from Beaverton Toyota. I was able to find the answer on Toyota Owners website, link below. You are safe and good to go. It’s the Security Indicator and there’s a tab that has the details listed. Have a great day! https://www.toyota.com/owners/resources/dashboard-lights/prius/2007?garagePrefVehicle=0&garageModelName=Prius&garageYearValue=2007&addToVehicleList=false&remRecentVehicle=false&csrfToken=15742767993172279996696518621755
Hmmmm. Not sure. I would Google it or take it to an auto parts store. Maybe they have a code reader?
