Hey, guys. I'm a new driver and recently got a Toyota Prius 2005 hybrid as a present from my parents and I have a semi-urgemt question to ask because I don't really know what I'm doing yet.... Sooo on the dashboard I have a fuel indicator. It is a horizontal line that has the letter R on the left, 1/2 written in the middle and 1/1 written on the far right. I was wondering if 1/2 and 1/1 are both indicators of the amount of gasoline or whether 1/2 meant the level of gas and 1/1 the electricity....I just wanna know if I have to refuel.... I know that I'm asking a reallyyyy stupid question....soryyy for that...
